Referring to fig. 1 to 6 together, fig. 1 is a schematic flow chart of a first embodiment of a method for manufacturing a heat conduction device of the present invention, fig. 2 is a schematic view of a plate manufactured in a plate manufacturing step of the first embodiment of the method for manufacturing a heat conduction device of the present invention, fig. 3 is a top view of fig. 2, fig. 4 is a schematic view of a plate during a positioning step of the first embodiment of the method for manufacturing a heat conduction device of the present invention, fig. 5 is a schematic view of a plate manufactured after the positioning step of the first embodiment of the method for manufacturing a heat conduction device of the present invention, and fig. 6 is a schematic view of a heat conduction device manufactured in the first embodiment of the method for manufacturing a heat conduction device of the present invention.

The manufacturing method of the heat conduction device comprises the following steps:

a plate producing step S11: manufacturing a plate 1, wherein the plate 1 is provided with a plurality of flow channels 101, the flow channels 101 are not mutually communicated, the flow channels 101 are respectively arranged by penetrating through the plate along an axis C which is mutually parallel, and the flow channels 101 form a first opening 102 and a second opening 103 at two ends of the plate 1;

a positioning step S12: except for the first opening 102 and the second opening 103 adjacent to two opposite long sides of the plate 1, the first opening 102 of each flow channel 101 and the second opening 103 of the adjacent flow channel 101 abut against each other, so that the flow channels 101 are communicated with each other;

a connection step S13: fixing two ends of the plate 1 which are abutted against each other, so that a plurality of runners 101 are connected with each other to form a spiral runner 106; the first opening 102 and the second opening 103 adjacent to the two opposite long sides 1A of the plate 1 are respectively defined as an inlet 102A and an outlet 103A, the inlet 102A is used for providing a heat transfer fluid to flow into the spiral channel 106, and the outlet 103A is used for providing a heat transfer fluid to flow out of the spiral channel 106.

As shown in fig. 1 and fig. 2, in the plate manufacturing step S1 of the present embodiment, each of the flow channels 101 penetrates through the plate along the axis C parallel to one of the long sides 1A of the plate 1, and the flow channels 101 are formed in the plate 1 side by side. The manner of forming the plurality of flow channels 101 in the plate member 1 is not limited herein.

In the present embodiment, each flow channel 101 is substantially rectangular, and the first opening 102 and the second opening 103 are both rectangular, but the shape of each flow channel 101 is not limited thereto, and in a special application, the flow channel 101 may also be cylindrical, and each of the first opening 102 and the second opening 103 may be correspondingly circular.

It should be noted that in the plate manufacturing step S1, the sizes of the formed flow channels 101 are all the same, that is, the length, the width, and the height of each flow channel 101 are all the same, and the shapes of each first opening 102 and each second opening 103 are also all the same.

As shown in fig. 2 to 4, in the positioning step S2, the plate 1 manufactured in the plate manufacturing step S11 may be bent by an inclination rolling method, and the inclination in the inclination rolling method may be determined according to the width of each flow channel 101, the interval distance between two adjacent flow channels 101, and the like, and preferably, the inclination may be 10 degrees. That is, in the positioning step S12, both ends of the plate member 1 may be bent in a direction to approach each other using the relevant mechanical device, and one of the ends of the plate member 1 may be slightly twisted with respect to the other end, thereby abutting one and the other ends of the plate member 1 in a mutually displaced manner.

In practical applications, in the plate manufacturing step S11, the thickness T of the side wall 11 between the flow channels 101 may be not greater than 15 mm, so that the first openings 102 and the second openings 103 can be relatively easily abutted against each other in the positioning step S2.

As shown in fig. 5 and 6, in the connection step S14, the two ends of the plate 1 may be connected and fixed to each other by welding, but not limited thereto, and in practical applications, the two ends of the plate 1 may be connected to each other by selecting a corresponding manner according to the actual material of the plate 1. It should be noted that, as shown in fig. 2 to 5, in the specific implementation of the positioning step S12, the plate 1 shown in fig. 2 may be bent to the state shown in fig. 4 by using a relevant tool, a relevant device, and the like, and the two ends of the plate 1 may be stably abutted against each other by using a relevant fixing mechanism such as a relevant clamp, so as to facilitate a relevant person or a relevant mechanical device to perform a welding operation on the two ends of the plate 1 abutted against each other (i.e., the connecting step S14).

As shown in fig. 4 to 6, the heat conducting device 100 manufactured by the method of manufacturing a heat conducting device of the present invention has a receiving channel 107 in the middle, the receiving channel 107 can be used to be sleeved outside a device that needs heat dissipation or heating, for example, the heat conducting device 100 can be sleeved outside a motor, when the motor is running, the cooling fluid L flows into the spiral flow channel 106 from the inlet 102A of the heat conducting device 100, so that the cooling fluid flows along the spiral flow channel 106 from one end of the heat conducting device 100 to the other end of the heat conducting device 100, and finally leaves the heat conducting device 100 from the outlet 103A, so as to take away the heat energy generated by the running of the motor. As shown in fig. 6, that is, after entering the heat conducting device 100 from the inlet 102A, the cooling fluid L moves along a spiral path P shown in the figure from one end of the heat conducting device 100 to the other end, and flows out from the outlet 103A of the heat conducting device 100.

In a specific implementation, a pipeline joint may be fixedly disposed at each of the inlet 102A and the outlet 103A, and a pipeline used for transporting the heat transfer fluid may be conveniently communicated with the spiral flow channel 106 through the pipeline joint.

As shown in fig. 8, in the sealing step S4, a sealing member 2 may be fixed to a first opening (i.e., the inlet 102A) and a second opening (i.e., the outlet 103A) adjacent to two opposite long sides 1A of the plate 1. The sealing member 2 may be made of the same material as the plate member 1, and the sealing member 2 may be fixed to the plate member 1 by welding, for example. In different embodiments, the first opening and the second opening may not be sealed by the sealing member 2, for example, the periphery of the first opening and the periphery of the second opening adjacent to the two opposite long sides 1A of the plate member 1 may be respectively melted, and then the first opening and the second opening are sealed by the related tool.

As shown in fig. 8, in the perforation step S15, the first perforation 104 may be adjacent to a first opening (i.e., the inflow opening 102A) and the second perforation 105 may be adjacent to a second opening (i.e., the outflow opening 103A), but the arrangement positions and the arrangement numbers of the first perforation 104 and the second perforation 105 are not limited to those shown in the figure, and they may be varied according to the needs.

It should be noted that, in practical applications, a pipe joint 3 may be respectively installed in the first through hole 104 and the second through hole 105, the pipe joint 3 is used for connecting with an external pipe, and a pipe for transporting a heat transfer fluid may be communicated with the spiral flow channel in the heat transfer device 100 through the pipe joint 3.
