In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

An air outlet pipe assembly 100 for a reservoir 1000 according to an embodiment of the first aspect of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 6, the outlet pipe assembly 100 includes two outlet pipes 1, and the two outlet pipes 1 are spaced apart from each other, so that the two outlet pipes 1 are spaced apart from each other and do not directly contact each other, and the spaced distance between the two outlet pipes 1 is greater than 0. Wherein, the central axis of the air outlet pipe 1 can extend along a straight line or a curve; the cross-sectional shape of the outlet pipe 1 may be circular, polygonal, or the like.

As shown in fig. 1 to 6, the outlet pipe assembly 100 further includes a connecting pipe 2, the connecting pipe 2 is disposed between the two outlet pipes 1, and both ends of the connecting pipe 2 are connected to the pipe walls 11 of the two outlet pipes 1, respectively. For example, the two ends of the length of the connecting pipe 2 are respectively a first end and a second end, the outlet pipe 1 has a pipe wall 11, the pipe wall 11 can be formed into an annular structure, the pipe wall 11 defines an outlet passage 10 of the outlet pipe 1, the first end of the connecting pipe 2 is connected with the pipe wall 11 of one of the two outlet pipes 1, and the second end of the connecting pipe 2 is connected with the pipe wall 11 of the other of the two outlet pipes 1. Wherein the central axis of the connecting tube 2 may extend along a straight line or a curved line; the cross-sectional shape of the connection pipe 2 may be circular, polygonal, or the like.

Have connection opening 110 on outlet duct 1's the pipe wall 11, connection opening 110 can run through outlet duct 1's pipe wall 11 in order to communicate with outlet duct 1's outlet channel 10, the length both ends of connecting pipe 2 have tip mouth of pipe 20 respectively, connection opening 110 is used for the tip mouth of pipe 20 butt joint with connecting pipe 2, then the connection opening 110 of one of them outlet duct 1 docks with the tip mouth of pipe 20 of the length one end of connecting pipe 2, another connection opening 110 of outlet duct 1 docks with the tip mouth of pipe 20 of the length other end of connecting pipe 2, make two outlet channel 1's outlet channel 10 pass through connecting pipe 2 intercommunication. From this, when outlet duct subassembly 100 is applied to reservoir 1000, outlet duct subassembly 100 can be established in the casing 200 of reservoir 1000, and outlet duct subassembly 100 can be located between the breathing pipe subassembly 400 and the blast pipe 601 of reservoir 1000, because the outlet channel 10 of two outlet ducts 1 passes through connecting pipe 2 intercommunication, then gaseous state refrigerant in the reservoir 1000 can be discharged through two outlet ducts 1, the cross-sectional area that the refrigerant flows has been increased, the velocity of flow of refrigerant in outlet duct 1 has been reduced, thereby the resistance of refrigerant in outlet duct 1 has been reduced, the on-way resistance loss of refrigerant in outlet duct 1 has been reduced.

Wherein, the connecting opening 110 and the end pipe orifice 20 of the corresponding side are not welded fully, so that the connecting opening 110 of one of the air outlet pipes 1 and the end pipe orifice 20 of one of the connecting pipes 2 are not welded fully, and the connecting opening 110 of the other air outlet pipe 1 and the other end pipe orifice 20 of the connecting pipe 2 are not welded fully, thereby ensuring the connection reliability of the air outlet pipe 1 and the connecting pipe 2, and facilitating the welding between the air outlet pipe 1 and the connecting pipe 2; for among some technologies, adopt welder to carry out full circle full weld with connection opening 110 and tip mouth of pipe 20, welder needs sufficient operating space in welding process, interval between two outlet duct 1 needs to satisfy welder operating space's demand promptly, lead to the overall structure size of outlet duct subassembly 100 great, occupation space is great, this application can be under the prerequisite that does not increase outlet duct subassembly 100 occupation space, be favorable to realizing that the welding of outlet duct 1 and connecting pipe 2 links to each other, be convenient for the processing of outlet duct subassembly 100, and the reinforcing maneuverability.

It is understood that "full weld" also known as "full weld" means that all the places of contact of two workpieces to be welded together are welded; the edge of the connecting opening 110 may be a closed ring, the edge of the end pipe orifice 20 may also be a closed ring, and the connecting opening 110 and the end pipe orifice 20 are not welded completely, and it may be understood that, when the connecting opening 110 is butted with the end pipe orifice 20, in the process of welding and connecting the connecting pipe 2 and the outlet pipe 1, the edge of the end pipe orifice 20 is not welded completely with the pipe wall 11 of the outlet pipe 1, and part of the edge of the end pipe orifice 20 is not welded with the pipe wall 11 of the outlet pipe 1, so that the length of the weld seam between the outlet pipe 1 and the end pipe orifice 20 is less than the length of the edge of the end pipe orifice.

According to the air outlet pipe assembly 100 for the accumulator 1000, the on-way resistance loss of the refrigerant in the air outlet pipe 1 is effectively reduced, and when the accumulator 1000 with the air outlet pipe assembly 100 is applied to a compressor, the volumetric efficiency of the compressor is improved; meanwhile, the connection reliability of the air outlet pipe 1 and the connecting pipe 2 is guaranteed, the air outlet pipe 1 and the connecting pipe 2 are connected in a welding mode on the premise that the occupied space of the air outlet pipe assembly 100 is not increased, the air outlet pipe assembly 100 is convenient to machine, and operability is improved.

It is understood that the connecting tube 2 may be one or more; for example, in the example of fig. 1 and 4, there is one connecting pipe 2, and two outlet pipes 1 are communicated by one connecting pipe 2; for another example, in the example of fig. 3 and 6, there are two connection pipes 2, each connection pipe 2 is connected between two outlet pipes 1, the two connection pipes 2 may be arranged at intervals in the axial direction of the outlet pipe 1, and the two outlet pipes 1 are communicated through the two connection pipes 2. When there are a plurality of connecting pipes 2, the intersecting lines of the connecting pipes 2 and the outlet pipe 1 may be the same or different.

In the description of the present invention, "a plurality" means two or more.

In some embodiments, the portion of the end nozzle 20 far from the center of the connection pipe 2 is welded to the connection opening 110, and the central portion of the end nozzle 20 near the connection pipe 2 is in clearance fit with the connection opening 110, so that the portion, which is required to operate and easily interferes with the outlet pipe 1, can be avoided by reasonably distributing the welding portion of the end nozzle 20 and the connection opening 110, and the portion is in clearance fit with the connection opening 110, thereby facilitating the simplification of the processing technology of the outlet pipe assembly 100 and improving the processing efficiency. Wherein the joining of portions of the end nozzle 20 with portions of the weld connecting opening 110 may form a weld joint segment 100a and the clearance-fitting of portions of the end nozzle 20 with portions of the weld connecting opening 110 may form a clearance-fitting segment 100 c.

For example, as shown in fig. 1 to 6, the end nozzle 20 may be formed in a shape of a intersecting line intersecting the outlet pipe 1 and the connecting pipe 2, and the end nozzle 20 may have a first portion and a second portion, and the first portion is relatively far away from the center of the connecting pipe 2 relative to the second portion, so that the second portion is located between the center of the connecting pipe 2 and the first portion in the axial direction of the connecting pipe 2, and an operation space required for welding the first portion and the connecting opening 110 is not easily interfered with the outlet pipe 1, thereby facilitating the operation of the welding gun, and the second portion is in clearance fit with the connecting opening 110, so that the operation space required for welding the second portion and the connecting opening 110 is prevented from being interfered with the outlet pipe 1, and the welding gun is prevented from being interfered with the outlet pipe 1 and/or the connecting.

For example, in the example of fig. 2 and 5, after the end nozzle 20 is butted against the connection opening 110 and welded, the end nozzle 20 and the connection opening 110 may have a plurality of weld joint sections 100a and a plurality of clearance fit sections 100c therebetween, and the plurality of weld joint sections 100a and the plurality of clearance fit sections 100c are alternately arranged in sequence along the circumferential direction of the end nozzle 20, that is, one clearance fit section 100c is provided between two adjacent weld joint sections 100a, and one weld joint section 100a is provided between two adjacent clearance fit sections 100 c. Thus, a first portion of the end nozzle 20 corresponds to the weld joint section 100a between the end nozzle 20 and the joint opening 110, and a second portion of the end nozzle 20 corresponds to the clearance fit section 100c between the end nozzle 20 and the joint opening 110.

In some embodiments, as shown in fig. 1-6, the weld connection includes at least one continuous weld 100f extending along the circumference of the end nozzle 20, the length of the continuous weld 100f is L, the diameter of the outlet tube 1 is D1, and the diameter of the connecting tube 2 is D2, wherein 0.2 ≦ D2/D1 ≦ 1, to facilitate welding the connecting opening 110 of the outlet tube 1 with the end nozzle 20 of the connecting tube 2. When the orthographic projection of the continuous welding seam 100f extends along a straight line, as shown in fig. 1-3, the length L of the continuous welding seam 100f satisfies that L is more than or equal to 2mm and less than or equal to 0.6D2 (namely 0.6 time of D2), namely the length L of the continuous welding seam 100f is selected from 2mm to 0.6D2 (including end points); when the orthographic projection of the continuous weld joint 100f extends along a curve, as shown in fig. 4-6, the length L of the continuous weld joint 100f satisfies that L is greater than or equal to 5mm and less than or equal to D2, that is, the length L of the continuous weld joint 100f is selected between 5mm and D2 (including end points).

It is understood that the length L of the continuous weld bead 100f refers to the curvilinear length of the continuous weld bead in the circumferential direction of the end nozzle 20. The diameter D1 of the outlet pipe 1 can be understood as the outer diameter of the outlet pipe 1, and the diameter D2 of the connecting pipe 2 can be understood as the outer diameter of the connecting pipe 2. The orthographic projection of the continuous weld 100f may refer to an orthographic projection on the longitudinal sections of the outlet duct 1 and the connecting duct 2.

In some embodiments, the clearance of the clearance fit is less than or equal to 0.1mm, and the fit clearance between the second portion and the connection opening 110 is less than or equal to 0.1mm, so that the communication reliability between the air outlet pipe 1 and the connection pipe 2 is ensured, the normal operation of the liquid reservoir 1000 is ensured, and the influence on the normal operation of the liquid reservoir 1000 due to the overlarge fit clearance between the end pipe orifice 20 and the connection opening 110 is avoided. Wherein, the clearance of clearance fit can be 0.02mm, or 0.05mm, or 0.09mm, etc.

In some embodiments, the weld connection comprises at least one continuous weld 100f extending along the circumference of the end nozzle 20, the length of the continuous weld 100f is L, the diameter of the outlet pipe 1 is D1, and the diameter of the connecting pipe 2 is D2, wherein D2/D1 is 0.2 ≦ D1 ≦ 1, so as to facilitate the welding of the connecting opening 110 of the outlet pipe 1 and the end nozzle 20 of the connecting pipe 2; when the orthographic projection of the continuous welding line 100f extends along a straight line, L is more than or equal to 2mm and less than or equal to 0.6D2, and when the orthographic projection of the continuous welding line 100f extends along a curve, L is more than or equal to 5mm and less than or equal to D2. And the clearance of clearance fit is less than or equal to 0.1 mm. From this, connecting pipe 2 and 1 welding of outlet duct are firm, and the intercommunication between connecting pipe 2 and the outlet duct 1 is reliable, has guaranteed reservoir 1000 normal operating.

Optionally, the weld connection comprises at least one continuous weld 100f extending in the circumferential direction of the end nozzle 20, i.e. the weld connection comprises one continuous weld 100f or a plurality of continuous welds 100f, the continuous weld 100f extending in the circumferential direction of the end nozzle 20. When the weld joint includes a plurality of continuous welds 100f, at least two adjacent continuous welds 100f with orthogonal projections extending along a straight line may be continuously disposed to form a weld joint section 100a with an orthogonal projection being a zigzag (as shown in fig. 2), of course, any two adjacent continuous welds 100f with an orthogonal projection extending along a straight line in the plurality of continuous welds 100f may also be discontinuously disposed, that is, discontinuously disposed (this example is not shown in the figure), and at this time, each continuous weld 100f with an orthogonal projection extending along a straight line may form a weld joint section 100a with an orthogonal projection extending along a straight line; when the weld joint includes a plurality of continuous welds 100f, the continuous welds 100f having an orthographic projection extending along a curve may constitute a weld joint section 100a having an orthographic projection extending along a curve (as shown in fig. 5).

The length L of each continuous weld seam 100f is between 2mm and 10mm inclusive, and the width of each continuous weld seam 100f is between 0.5mm and 2mm inclusive.

Alternatively, in the example of fig. 1 to 6, two outlet pipes 1 are arranged in parallel, the central axes of the two outlet pipes 1 may define a first predetermined plane 101 (for example, the paper surface on which the structure of fig. 1 is located), a connecting pipe 2 is connected between the two outlet pipes 1, and the central axis of the connecting pipe 2 is also located in the first predetermined plane 101, so that the first predetermined plane 101 may be understood as the longitudinal section of the outlet pipe 1 and the longitudinal section of the connecting pipe 2.
