Technical Field

The present invention relates to a tank mounting structure and a tank mounting method in which a tank is mounted on a plate.

Background

JP58-165489U discloses a tank mounting structure including: a tank forming a flow path of the heat exchanger; and a header plate that fixes an open end of the tank.

A plurality of end claw portions protrude from the tank so as to be aligned in a row. The header plate has: a peripheral edge portion extending along an open end of the can; and a locking window which is opened at the peripheral edge part and is engaged with the end claw part.

In manufacturing the heat exchanger, the peripheral edge portion is bent to engage the engagement window with the end claw portion in a state where the tank is assembled to the header plate. Thus, the end claw portion abuts against the locking window and is clamped (Japanese add められ る), whereby the tank is fixed to the header plate.

Disclosure of Invention

However, in the tank mounting structure described in JP58-165489U, in order to sufficiently secure the strength of the header plate, the header plate needs to be formed large, which leads to an increase in the size of the heat exchanger.

The invention aims to miniaturize a tank mounting structure.

According to an aspect of the present invention, there is provided a tank attachment structure for attaching an open end portion of a tank to a plate, the tank having a projection projecting from the open end portion, the plate having: an extension extending along the open end; and a hole that is opened in the extension portion and is engaged with the protrusion, the hole having, on an inner circumference thereof: a fixing edge that abuts against the projection to fix the tank to the plate; and a side edge bent from the fixing edge to be inclined at an acute angle with respect to the fixing edge.

According to the above aspect, in the extended portion, the stress generated by the reaction force received by the fixed edge from the protrusion is dispersed to the periphery of the side edge. Thus, the tank mounting structure suppresses concentration of stress on the extending portion, and can be downsized by reducing the plate thickness of the plate.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows a heat exchanger 1 having a tank mounting structure according to the present embodiment. For simplification of the description, a part of the heat exchanger 1 is omitted and shown.

The heat exchanger 1 is used as a water-cooled intercooler that cools intake air (fluid) supercharged by an engine (not shown) by coolant (medium).

The heat exchanger 1 includes: a pair of tanks 10 (flow path members) that guide intake air; and a core 30 as a heat exchanging part for circulating a cooling liquid. The core 30 is sandwiched between a pair of the cans 10. The intake air flowing through the core 2 via the tank 10 is cooled by radiating heat to the coolant flowing through the core 2.

The metal core 30 includes: a plurality of stacked tubes (not shown); a plurality of core plates 31 (flow path members) formed in a box shape that houses the tubes; and a pair of pipes 33 connected to the core plate 31. During operation of the engine, the coolant delivered from a pump (not shown) through the pipe flows into the pipe through one pipe 33 as indicated by a black arrow, flows through the pipe, and then flows out of the other pipe 33.

The resin tank 10 includes: a roof-shaped open end portion 11 that opens toward the core 30; and a cylindrical tube portion 13 that opens toward the side opposite to the core 30. A catheter (not shown) is connected to the cylinder 13. As indicated by hollow arrows, the intake air flows into the core plate 31 through one of the tanks 10, flows around the pipes, and then flows out from the other tank 10.

Fig. 2 is a front view showing a tank mounting structure. A frame-shaped plate 40 is joined to the open end of the core plate 31. The open end 11 of the can 10 is mounted to the core 30 by means of a plate 40.

The opening end portion 11 is formed in a cylindrical shape having a substantially rectangular cross-sectional shape. The open end 11 has a pair of short sides 11A and a pair of long sides 11B extending across the short sides 11A. Thereby, the open end portion 11 forms a flow path having a substantially rectangular cross section.

A groove 32 as a housing groove for housing the open end 11 is formed between the plate 40 and the core 30. The slot 32 is formed in a generally rectangular ring shape extending around the core 30. A seal member (not shown) is interposed between the groove 32 and the opening end portion 11 of the can 10. The sealing member is formed of an elastic material such as a rubber material.

The plate 40 has an L-shaped cross-sectional shape. The plate 40 is not limited to this, and may have an S-shaped cross-sectional shape. In this case, the slots 32 are not formed by the core 30 but only by the plate.

The plate 40 has an extension 42 extending along the periphery of the open end 11. A plurality of holes 50 that engage with the respective projections 15 are formed in the extension portion 42. The extending portion 42 is formed in a plate shape extending along the opening end portion 11, and the holes 50 are aligned in a row and opened. In addition, the extension portion 42 may be formed by arranging a plurality of claw-shaped portions, and the hole 50 may be opened in each claw-shaped portion.

Next, the shapes of the projection 15 and the hole 50 will be described with reference to fig. 3.

The protrusion 15 is formed as a convex portion having a substantially rectangular shape in cross section. The projection 15 has a front end 16, a rear end 17, a pair of side ends 18, 19, a top end 20, and 4 corners 21-24. The 4 corners 21-24 are bent at right angles.

The front end 16 and the rear end 17 are formed in planar shapes extending parallel to each other. The pair of side ends 18, 19 are formed in planar shapes extending parallel to each other.

On the other hand, the inner periphery (inner surface) of the hole 50 is formed in a substantially trapezoidal shape. The inner periphery of the hole 50 has: a fixed side 51 (long side) abutting against the projection 15; an opposite side 52 (short side) which is opposite to the fixed side 51; a pair of side edges 53, 54 extending between the fixed edge 51 and the opposite edge 52; and 4 corners 55-58.

The fixed side 51, the opposite side 52, and the side edges 53, 54 extend linearly (planar) along a trapezoid T shown by a two-dot chain line in the figure. Further, the present invention is not limited to this, and the fixed edge 51, the opposite edge 52, and the side edges 53 and 54 may extend in a curved line. The side edges 53, 54 are inclined at an acute angle less than a right angle with respect to the fixed edge 51.

The 4 corners 55-58 are curved in an arc shape. The corners 55 to 58 may be curved linearly along a trapezoid T shown by a two-dot chain line in the figure.

A conical recess 63 is formed between the side edge 53 and the side end 18 of the projection 15. In the direction in which the fixed side 51 extends (in fig. 3, the left-right direction), the opening width L of the void 63 gradually becomes smaller as it goes away from the fixed side 51. Similarly, a tapered gap 64 is formed between the side 54 and the side 19 of the projection 15. A gap 62 is formed between the opposite edge 52 and the rear end 17 of the projection 15.

Fig. 4 is a front view of the heat exchanger 1 showing a chucking process for fixing the tank 10 to the plate 40 when the heat exchanger 1 is manufactured. In the chucking step, in a state where the can 10 is assembled to the plate 40, the base end portion of each extending portion 42 is bent from the seat portion 41 (see fig. 2) as indicated by an arrow in the drawing. As a result, as shown in fig. 1, the extending portions 42 come to positions along the opening end portion 11 of the can 10, and the fixing edges 51 of the holes 50 engage with the front ends 16 of the projections 15 and are fastened. Thus, the tank 10 is fixed to the plate 40. As described above, the heat exchanger 1 is manufactured.

Next, the operation of the heat exchanger 1 will be described.

During operation of the heat exchanger 1, the end surface of the tank 10 at the opening end 11 receives the elastic restoring force of the seal member, and the inner surface of the tank 10 receives the pressure of the intake air. The can 10 is supported so as not to be separated from the plate 40 by the protrusion 15 engaged with the hole 50. At this time, the tip 16 of the protrusion 15 engaged with the fixed edge 51 of the hole 50 applies a tensile load to the extension portion 42. Stress is generated in the extended portion 42 due to the reaction force received by the fixing edge 51 from the front end 16 of the projection 15. In the extended portion 42, the side edges 53, 54 are deformed so as to widen the angle inclined with respect to the fixed edge 51, and the stress is dispersed to the periphery of the side edges 53, 54.

Fig. 5A is a diagram showing distribution of stress generated in the extending portion 42 in a tank mounting structure in which the side edge 53 of the hole 50 is not inclined with respect to the fixed edge 51 but is orthogonal to the fixed edge 51 as a comparative example. In the extending portion 42, the stress increases in the order of the regions S1, S2, S3, S4, and S5 around the side 53, and the stress concentrates on the regions S4 and S5 located in the vicinity of the corner 57.

Fig. 5B is a diagram showing the distribution of stress generated in the extension portion 42 of the present invention. In the extending portion 42, the stress increases in the order of the regions S1, S2, and S3 around the side 53, and the stress is suppressed from concentrating on the region S3 located in the vicinity of the corner 57.

Next, the effects of the present embodiment will be described.

The tank mounting structure of the heat exchanger 1 includes a tank 10 and a plate 40 to which the tank 10 is mounted. The tank 10 has: an open end 11 fixed to the plate 40; and a protrusion 15 protruding from the periphery of the open end portion 11. The plate 40 has: an extension 42 extending along the periphery of the open end 11; and a hole 50 opened in the extension 42 and engaged with the projection 15. The can 10 is attached to the plate 40 by engaging the hole 50 with the protrusion 15. The inner periphery of the hole 50 has: a fixing edge 51 which abuts on the projection 15 to fix the tank 10 to the plate 40; and side edges 53, 54 bent from the fixed edge 51 to be inclined at an acute angle with respect to the fixed edge 51.

According to the above configuration, in the extended portion 42, the stress is dispersed to the periphery of the side edges 53, 54 due to the reaction force received by the fixed edge 51 from the front end 16 of the protrusion 15. Thus, the tank mounting structure of the heat exchanger 1 suppresses concentration of stress on the extension portion 42, and can be reduced in size by reducing the plate thickness of the plate 40.

Further, the inner periphery of the hole 50 has a pair of side edges 53, 54 extending on both sides of the protrusion 15. The interval W in the direction in which the fixed edge 51 extends between the pair of side edges 53, 54 becomes smaller as it goes away from the fixed edge 51.

According to the above configuration, the fixed edge 51 is deformed so as to expand the distance W between the pair of side edges 53 and 54 by the reaction force received from the tip 16 of the protrusion 15, and the stress generated in the extending portion 42 is dispersed over a wide range.

Here, fig. 6A shows a tank mounting structure having a substantially rectangular hole 70 as a comparative example. In this case, a space L2 provided between the corner 77 and the corner 78 is provided between the adjacent holes 70. If the interval L2 becomes short, stress tends to concentrate near the corner 77 and the corner 78.

In contrast, the inner periphery of the hole 50 of the tank mounting structure of the present invention has a substantially trapezoidal shape having the opposite side 52 extending so as to be bent from the pair of side edges 53 and 54 to be opposite to the fixed side 51.

According to the above configuration, as shown in fig. 6B, in the substantially trapezoidal holes 50, the interval L1 provided between the corner 57 and the corner 58 is sufficiently ensured between the adjacent holes 50, and the stress generated in the extension portion 42 is dispersed in a wide range.

Gaps 63 and 64 are formed between the fixing edge 51 and the side edges 53 and 54 and the protrusion 15. The gaps 63 and 64 are tapered such that the opening width in the direction in which the fixed edge 51 extends becomes smaller as the distance from the fixed edge 51 increases.

According to the above configuration, since the corners 55 and 56 of the hole 70 are distant from the projection 15, the stress is dispersed in a wide range by deforming the portions of the fixed side 51 facing the gaps 63 and 64, the corners 55 and 56, and the portions in the vicinity of the side edges 53 and 54.

Further, the plate 40 has a seat 41 extending by bending from the extending portion 42. The seat 41 engages with the core 30 of the heat exchanger 1. A groove 32 for accommodating the open end 11 is formed between the extension portion 42 and the seat portion 41 and the core 30.

According to the above structure, the plate 40 has an L-shaped cross section. Therefore, the heat exchanger 1 can be miniaturized by suppressing the size of the plate 40 protruding from the core 30.

A chamfered portion (not shown) extending in a curved shape in which the front end 16, the rear end 17, and the side ends 18 and 19 are curved toward the front end 20 may be formed at the front end of the projection 15. Thus, in the clamping step in which the extending portions 42 are bent, the holes 50 are smoothly engaged with the chamfered portions of the protrusions 15 in sliding contact.

Next, a modification of the projection 15 shown in fig. 7A, 7B, and 7C will be described.

A pair of corners 23, 24 of the projection 15 shown in fig. 7A connected to the rear end 17 are curved in a substantially circular arc shape. The rear end 17 is formed in a curved surface shape curved to the tip 20. In this case, in the chucking step in which each of the extending portions 42 is bent, the hole 50 is smoothly engaged with the substantially arc-shaped corners 23 and 24 of the protrusion 15 and the curved portion of the rear end 17 by sliding contact.

The projection 15 shown in fig. 7B is formed as a convex portion having a substantially trapezoidal cross section. The pair of side ends 18, 19 are formed in a planar shape extending obliquely to each other. In this case, in the clamping step in which the extending portions 42 are bent, the substantially trapezoidal holes 50 are smoothly engaged with the side ends 18, 19 of the protrusions 15 in sliding contact.

The projection 15 shown in fig. 7C is formed as a convex portion having a substantially semicircular shape in cross section. The projection 15 has a front end 16 formed in a planar shape and a rear end 17 formed in a curved surface in a substantially semicircular arc shape. In this case, in the clamping step in which the extending portions 42 are bent, the holes 50 are smoothly engaged with the approximately semicircular arc-shaped rear ends 17 of the projections 15 in sliding contact.

Next, a modification of the projection 15 and the hole 50 shown in fig. 8A, 8B, and 8C will be described.

The projection 15 shown in fig. 8A is formed as a convex portion having a substantially semicircular shape in cross section. The projection 15 has a front end 16 formed in a planar shape and a rear end 17 formed in a curved surface in a substantially semicircular arc shape. On the other hand, the hole 50 has a substantially semicircular inner periphery, like the protrusion 15. The inner periphery of the hole 50 has a fixed edge 51 abutting against the projection 15 and a pair of side edges 53, 54 extending in an arc shape from both ends of the fixed edge 51. In this case, in the chucking step in which the extending portions 42 are bent, the side edges 53 and 54 of the hole 50 are smoothly engaged with the substantially arc-shaped outer peripheries of the protrusions 15 in sliding contact.

The projection 15 shown in fig. 8B is formed as a convex portion having a substantially triangular shape in cross section. The projection 15 has a front end 16 formed in a planar shape and a pair of side ends 18, 19 inclined in a substantially triangular shape. Like the hole shown in fig. 3, the hole 50 has a substantially trapezoidal inner periphery. In this case, in the clamping step in which the extending portions 42 are bent, the side edges 53 and 54 of the hole 50 are smoothly engaged with the side edges 18 and 19 of the protrusion 15 having a substantially triangular shape in a sliding contact manner.

The projection 15 shown in fig. 8C is formed as a convex portion having a substantially triangular shape in cross section. The projection 15 has a front end 16 formed in a planar shape and a pair of side ends 18, 19 inclined in a substantially triangular shape. The hole 50 has a substantially triangular inner periphery, as with the protrusion 15. The inner periphery of the hole 50 has a fixed side 51 abutting against the projection 15 and a pair of side edges 53 and 54 inclined from both ends of the fixed side 51 in a substantially triangular shape. In this case, in the clamping step in which the extending portions 42 are bent, the side edges 53 and 54 of the hole 50 having the substantially triangular shape slide on the side edges 18 and 19 of the protrusion 15 having the substantially triangular shape, and are smoothly engaged with each other.

Next, the mounting of the tank 10 to the plate 40 will be described in detail with reference to fig. 9 to 13.

As shown in fig. 9, a seal member 36 is interposed between the open end 11 of the can 10 and the plate 40. The sealing member 36 is formed of an elastic material such as a rubber material.

The plate 40 includes a frame 45 in a frame shape into which the open end 11 is fitted, and an extension 42 extending from the frame 45 along the periphery of the open end 11.

The frame 45 has an L-shaped cross-sectional shape and is formed in a substantially rectangular frame shape extending around the core 30. The inner peripheral end of the frame portion 45 is joined to the core plate 31. A groove 32 as an annular receiving groove for receiving the open end 11 is formed between the frame portion 45 and the core plate 31 (core 30).

The open end 11 of the can 10 has an open end 25 extending opposite to the frame 45 of the plate 40, and a concave portion 29 and a convex portion 28 extending in a line on the side opposite to the open end 25.

The open end 25 extends in a substantially rectangular ring shape extending around the core 30, and abuts against the frame 45 of the plate 40. A seal groove 26 for accommodating a seal member 36 is opened at the opening end 25.

The protrusion 28 protrudes from the open end 25 at a constant distance (height), and extends substantially parallel to the open end 25.

The protrusion 28 extends around the flow passage wall 12 at a constant interval from the flow passage wall 12. The concave portion 29 is formed between the convex portion 28 and the flow path wall portion 12. The recess 29 is recessed on the opposite side of the open end 25 with respect to the open end 11, and opens in a direction away from the open end 25 (in fig. 9, the upper direction). The recess 29 is a groove-like depression around the flow path wall 12 and extends substantially parallel to the open end 25.

A plurality of projections 15 project in a row at the opening end 11 of the can 10. On the other hand, a plurality of holes 50 that engage with the respective projections 15 are formed in the extending portion 42 of the plate 40. The opening end 11 of the can 10 is fixed to the plate 40 by the engagement of the holes 50 with the projections 15.

The extending portion 42 is formed in a flat plate shape extending along the opening end portion 11. In addition, the extension portion 42 may be formed by arranging a plurality of claw-shaped portions, and the hole 50 may be opened in each claw-shaped portion. The extending portion 42 may not have the hole 50, and a claw-shaped portion may be bent along the opening end portion 11.

Next, a method of attaching the tank 10 to the plate 40 will be described.

As shown in fig. 10A to 12, when the heat exchanger 1 is manufactured, a step of attaching the tank 10 to the plate 40 is performed. In this step, a pair of jigs 150 arranged to sandwich the plate 40 and the can 10 is used.

The pair of jigs 150 are supported by guide rails (not shown) so as to move linearly, and are driven by a driving mechanism (not shown). Thereby, the pair of jigs 150 move along the frame 45 of the plate 40 and the open end 11 of the can 10 in synchronization with each other as shown by arrows in fig. 10A to 10C.

Fig. 13 is a perspective view showing the jig 150. The jig 150 is formed in a rail shape having a C-shaped cross-sectional shape. The jig 150 has: a support portion 151 that supports the frame portion 45 of the plate 40; an engaging portion 152 that engages with the recess 29 of the tank 10; a ramp-shaped pressing portion 153 that brings the can 10 close to the plate 40; and a bending portion 154 that bends the plate 40. The engaging portion 152 protrudes in a hook shape from a portion connected to the pressing portion 153 toward the supporting portion 151. The bent portion 154 protrudes in a tapered shape toward the plate 40 from a portion connected to the supporting portion 151 and the pressing portion 153.

The jig 150 has: a compression portion 155 in which the distance between the support portion 151 and the pressing portion 153 is gradually reduced in the range of the dimension D; and a clamping portion 156 which makes the protruding amount of the bending portion 154 gradually larger in the range of the dimension E.

Next, a process of attaching the tank 10 to the plate 40 will be described with reference to fig. 10A, 10B, and 10C.

First, as shown in fig. 10A, the can 10 is assembled to the plate 40, and the compression portion 155 of the jig 150 is fitted to the plate 40 and the can 10. Thereby, the one end side of the seal member 36 is compressed to a predetermined amount.

At this time, as shown in fig. 11, the support portion 151 of the jig 150 supports the back surface (lower surface) of the frame portion 45 of the plate 40, and the pressing portion 153 of the jig 150 abuts against the convex portion 28 of the can 10. Thereby, as shown by the solid arrows in fig. 11, the convex portion 28 of the can 10 approaches the frame portion 45 of the plate 40, and the sealing member 36 is compressed.

Next, as shown in fig. 10B, the jig 150 moves to the middle in a state of being fitted to the plate 40 and the can 10. Thereby, the open end 11 of the can 10 extends substantially parallel to the frame 45 of the plate 40, and the sealing member 36 is compressed to a predetermined amount.

Next, as shown in fig. 10C, the jig 150 is moved in a state of being fitted with the plate 40 and the can 10. Thus, the jig 150 passes, and the sealing member 36 is compressed by a predetermined amount over the entire region, and the extending portion 42 of the plate 40 is continuously bent.

At this time, since the bent portion 154 of the jig 150 is in sliding contact with the outer surface of the extended portion 42 of the plate 40, the extended portion 42 is bent so as to follow the open end portion 11 of the can 10 as shown by the arrow of the broken line in fig. 11. As a result, as shown in fig. 12, the hole 50 of the plate 40 engages with the protrusion 15 of the can 10, and the open end 11 of the can 10 is fastened to the plate 40.

As described above, the can 10 is attached to the plate 40. Thus, the heat exchanger 1 is manufactured.

Next, the effects of the present embodiment will be described.

The tank mounting structure includes a plate 40 to which the tank 10 is mounted. The plate 40 has: a frame 45 to which the open end 11 of the tank 10 is fitted; and an extension portion 42 that fastens and fixes the open end portion 11 between the extension portion and the frame portion 45. The open end 11 of the can 10 has: an open end 25 extending opposite the frame portion 45 of the plate 40; and a recess 29 recessed on the side opposite the open end 25. The recess 29 has a shape that engages with the jig 150 that performs positioning between the frame 45 and the open end 11 together with the frame 45.

In the can mounting method, the jig 150 that engages with the frame 45 of the plate 40 and the recess 29 of the can 10 to align the frame 45 and the open end 11 is used to perform clamping and fixing by the extending portion 42 of the plate 40.

According to the above configuration, the jig 150 engages with the frame 45 of the plate 40 and the recess 29 of the can 10, and the frame 45 and the open end 11 are aligned. This allows the open end 11 of the tank 10 to be accurately assembled to the plate 40, thereby improving the accuracy of the mounting position of the tank 10.

The jig 150 is not limited to the manufacturing of the heat exchanger 1, and may be used for maintenance of the heat exchanger 1.

Further, the jig 150 moves along the frame 45 of the plate 40 and the open end 11 of the can 10.

According to the above configuration, since the jig 150 moves to attach the open end 11 of the can 10 to the plate 40, the time required for attachment is shortened.

Further, the jig 150 includes: a support portion 151 that is in sliding contact with the frame portion 45 of the plate 40; and an engaging portion 152 that is in sliding contact with the recess 29 of the tank 10.

According to the above configuration, when the jig 150 moves, the reaction force of the curved extending portion 42 is supported by two portions, i.e., the supporting portion 151 and the engaging portion 152. This suppresses the plate 40 from being displaced from the jig 150 during clamping, and accurately bends the extending portion 42.

The jig 150 further includes a pressing portion 153 that comes into sliding contact with the open end 11 (the protruding portion 28) of the can 10 to bring the open end 25 of the can 10 closer to the frame 45 of the plate 40.

According to the above configuration, the jig 150 moves, and the open end 11 pressed by the pressing portion 153 is located at a predetermined position with respect to the frame portion 45. Thus, the opening end portion 11 of the can 10 is attached to the plate 40 in a state where the sealing member 36 is compressed to a predetermined amount, and therefore, the sealability of the can 10 is ensured.

The jig 150 further includes a bending portion 154 that slidably contacts the extending portion 42 of the plate 40 to bend the extending portion 42.

According to the above configuration, the jig 150 moves to bend the extension portion 42 pressed by the bending portion 154. Therefore, the fastening by the open end portion 11 of the extension portion 42 is reliably performed. In addition, the bending part 154 continuously bends the extension part 42 when the jig 150 moves, thereby shortening the time taken for the chucking and fixing.

The mechanism (not shown) for bending the extension portion 42 may be provided independently of the jig 150, without being limited to the above configuration.

However, in the conventional heat exchanger mounting process, the plate protruding from the core is placed on and supported by the jig. Therefore, in order to suppress the deviation of the plate from the jig, it is necessary to ensure a dimension (projection width) of the plate projecting from the core to some extent.

In contrast, in the present embodiment, since the jig 150 sandwiches and supports the plate 40 and the tank 10, even if the dimension (protruding width) of the plate 40 protruding from the core 30 is smaller than the conventional dimension, the plate 40 can be sufficiently prevented from being displaced from the jig 150. Therefore, the heat exchanger 1 can be miniaturized in the plate 40 and the open end 11 of the tank 10.

Further, the frame portion 45 of the plate 40 is joined to the core 30 of the heat exchanger 1.

According to the above configuration, the size of the frame portion 45 of the plate 40 of the heat exchanger 1 protruding from the core 30 is suppressed to be small, and downsizing can be achieved.

Further, the frame 45 of the plate 40 is joined to the core 30, and a groove 32 for housing the open end 11 is formed between the core 30 and the frame.

According to the above configuration, the frame 45 has an L-shaped cross-sectional shape, and the protruding dimension of the frame 45 from the core 30 is suppressed to be small. Therefore, the heat exchanger 1 can be miniaturized in the plate 40 and the open end 11 of the tank 10.

The frame portion 45 of the plate 40 is not limited to have an L-shaped cross section, and may have an S-shaped cross section. In this case, the slots 32 are not formed by the core 30 but only by the plate 40.

The embodiments of the present invention have been described above, and the above embodiments are merely some of application examples of the present invention, and the gist thereof is not intended to limit the scope of protection of the present invention to specific configurations of the above embodiments.

In the present embodiment, the tank 10 is a flow path member forming a flow path. The tank 10 is not limited to this, and may be a container provided as a container for storing gas, liquid, or the like.

In the present embodiment, the plate 40 is a single member extending in a frame shape (ring shape) along the opening end portion 11. Further, the plate 40 is not limited to this, and may be a member divided into a plurality of pieces along the opening end portion 11.

In the present embodiment, the extending portion 42 is a fastening member that is bent along the periphery of the open end portion 11. The extension portion 42 may be formed in advance along the periphery of the opening end portion 11. In this case, the extending portion 42 is elastically deformed to engage the hole 50 with the protrusion 15 of the can 10, thereby performing the chucking fixation.

The tank mounting structure of the present invention is suitable for a heat exchanger mounted on a vehicle, but is not limited thereto, and can be applied to equipment other than a heat exchanger.
