[0033] The utility model provides a kind of double-row heat exchanger 100, two manifold pipes of its side are connected by adapter seat 30, and the structure of adapter seat 30 is optimized to greatly reduce the occupied volume of adapter seat 30.
[0034] Please see Figures 1-2 , double-row heat exchanger 100 includes first heat exchange component 10, second heat exchange component 20 and adapter seat 30, first heat exchange component 10 includes first heat exchange structure 11 and at least one first manifold pipe 12, first manifold pipe 12 is connected to the first side of first heat exchange structure 11, and is arranged along its axial extension;Second heat exchange component 20 includes second heat exchange structure 21 and at least one second manifold pipe 22, second manifold pipe 22 is connected to the first side of second heat exchange structure 21, and is arranged along its axial extension, and the first side of first heat exchange structure 11 and the first side of second heat exchange structure 21 are the same side;Adapter seat 30 includes first adapter part 31 and second adapter part 32, first adapter part 31 is provided with first interface 311 on it, which is communicated with first manifold pipe 12, second adapter part 32 is provided with second interface 321 on it, which is communicated with second manifold pipe 22, first interface 311 and second interface 321 are communicated, first manifold pipe 12 and second manifold pipe 22 are axially parallel, and first interface 311 and second interface 321 are located at the same end along the axial direction of first manifold pipe 12 and second manifold pipe 22.
[0035] Thus, first heat exchange structure 11 in first heat exchange component 10 can carry out first heat exchange, second heat exchange structure 21 in second heat exchange component 20 can carry out second heat exchange, and the heat exchange efficiency of double-row heat exchanger 100 is improved by twice heat exchange.The first adapter part 31 of adapter seat 30 is communicated with first manifold pipe 12, and the second adapter part 32 is communicated with second manifold pipe 22, so that the medium in first manifold pipe 12 can pass through first adapter part 31 and second adapter part 32 from first interface 311 to second interface 321 and enter second manifold pipe 22.The first interface 311 and the second interface 321 on the adapter seat 30 are located at the same end along the axial direction of the first manifold pipe 12 and the second manifold pipe 22, so that the extension path is short, the occupied space is small, the processing technology is simple, the overall size of the double-row heat exchanger 100 is reduced, and the structure is compact.Because the first adapter part 31 and the second adapter part 32 are integrally formed, the adapter seat 30 does not need to be bent multiple times like the pipeline in the prior art to realize communication with the first manifold pipe 12 and the second manifold pipe 22, so the structure is more stable and is not easy to deform and break during processing and assembly.
[0036] It should be explained that the same end along the axial direction of the first manifold pipe 12 and the second manifold pipe 22 means that the first manifold pipe 12 has two ends in the length direction, and the second manifold pipe 22 also has two ends in the length direction, and the same end means that the two ends of the first manifold pipe 12 and the second manifold pipe 22 are close to each other.
[0037] Furthermore, the first interface 311 and the second interface 321 are respectively located at the same axial length position of the first manifold 12 and the second manifold 22. That is, the connection position of the first adapter portion 31 and the first manifold 12, and the connection position of the second adapter portion 32 and the second manifold 22 are at the same axial position, for example, both are located 10 mm or 20 mm from the end of the first manifold 12 and the second manifold 22 toward the other end. In this way, the processing of the adapter 30 is more convenient. On the basis of the parallel connection of the first manifold 12 and the second manifold 22, the connection of the first adapter portion 31 and the second adapter portion 32 at the same position can further shorten the occupied area of the adapter 30. Preferably, the extended length direction of the adapter 30 is perpendicular to both the first manifold 12 and the second manifold 22.
[0038] It can be understood that in other embodiments, the first interface 311 and the second interface 321 can also be opened at the same end on the first collecting pipe 12 and the second collecting pipe 22, but not at the same length position, but there is a deviation in the axial direction of the first collecting pipe 12 and the second collecting pipe 22, and the adapter 30 extends obliquely from the first interface 311 to the second interface 321, that is, in this embodiment, the extended length direction of the adapter 30 is set at an angle to the first collecting pipe 12 and the second collecting pipe 22.
[0039] The adapter 30 also includes a connecting portion 33, one side of which is connected to the first adapter portion 31 and the other side of which is connected to the second adapter portion 32. The first adapter portion 31, the second adapter portion 32, and the connecting portion 33 are integrally formed. As the three components are integrally formed, they do not need to be processed separately. This one-piece molding process makes processing more convenient and cost-effective. It also solves problems that can easily arise during the welding process, such as loose welds and poorly matched dimensions of the components due to tolerance issues.
[0040] The structure of the adapter 30 can be adapted to different working conditions and changed accordingly to produce various embodiments with different structures, which are described one by one here:
[0041] Example 1

As a result, due to the gap between the first header 12 and the second header 22, the presence of the connecting portion 33 allows the first adapter portion 31 and the second adapter portion 32 to correspond more accurately, thereby facilitating the connection between the first adapter portion 31 and the second adapter portion 32 and the first header 12 and the second header 22.
[0043] In the embodiment, the first adapter 31 and the second adapter 32 are arranged in parallel, the connecting part 33 is arranged perpendicularly to the first adapter 31, and the connecting part 33 is also arranged perpendicularly to the second adapter 32, so that the structure of the connecting part is more regular.
[0044] Preferably, referring to Figure 4 , the wall thickness X1 of the first adapter 31 and the second adapter 32 is set to 4mm≥X1≥2mm, so that the first adapter 31 and the second adapter 32 can save materials while meeting the strength. The distance between the axis of the first interface 311 and the axis of the second interface 321 is X2, and X2 is set to 60mm≥X2≥16mm, so that the positions of the first interface 311 and the second interface 321 can be more suitable for the positions of the first manifold 12 and the second manifold 22.
[0045] The first adapter 31 and the second adapter 32 are arranged flush with the end of the first manifold 12 and the second manifold 22, and the distance between the axis of the connecting part 33 and the end of the first adapter 31 and the second adapter 32 is set to X3, 35mm≥X3≥25mm. In this way, the distance between the connecting part 33 and the first manifold 12 and the second manifold 22 is appropriate, which can prevent the adapter 30 from occupying too much space, and also enable the first adapter 31 and the second adapter 32 to smoothly flow the medium.
[0046] Preferably, the first adapter 31 is connected to the outer side wall of the first manifold 12, and the end of the first adapter 31 close to the first manifold 12 is arranged in a circular arc shape, and the arc is adapted to the outer side wall of the first manifold 12. The second adapter 32 is connected to the outer side wall of the second manifold 22, and the end of the second adapter 32 close to the second manifold 22 is arranged in a circular arc shape, and the arc is adapted to the outer side wall of the second manifold 22. In this way, the adapter 30 can be more closely adapted to the first manifold 12 and the second manifold 22, avoiding leakage of the medium.
[0047] Preferably, the first adapter 31 and the second adapter 32 are arranged with the same arc, and the radius of the circle formed by the arc is X4, and X4 is set to 45mm≥X4≥12mm, so that it is adapted to the diameter of most manifolds.
[0048] Embodiment two
[0049] Please refer to Figure 5In the first direction along which the openings of the first interface 311 and the second interface 321 are oriented, the thickness of the connecting portion 33 in the first direction is greater than the thickness of the first adapter portion 31 and the second adapter portion 32 in the first direction. In this way, the connecting portion 33 can provide higher connection strength to the first adapter portion 31 and the second adapter portion 32, so that the structural strength of the adapter 30 is higher.
[0050] In the present embodiment, the first adapter portion 31 and the second adapter portion 32 are both attached to the connecting portion 33 and integrally formed, and no gap is provided between the first adapter portion 31 and the connecting portion 33 and between the second adapter portion 32 and the connecting portion 33, so as to further improve the structural strength. In the direction from the first adapter portion 31 to the connecting portion 33, the connection between the first adapter portion 31 and the connecting portion 33 is transitioned through a smooth arc surface, and in the direction from the second adapter portion 32 to the connecting portion 33, the connection between the second adapter portion 32 and the connecting portion 33 is also transitioned through a smooth arc surface, so as to further provide the load that the connecting portion can bear.
[0051] The connecting portion 33 is protrudingly arranged close to the first manifold 12 and the second manifold 22, and is located in the recess formed by the outer side wall of the first manifold 12 and the outer side wall of the second manifold 22, so as to reduce the space occupied thereby.
[0052] Embodiment Three

In this way, since the body segment 331 is arranged vertically with the first adapter 31 and the second adapter 32, the flow of the medium originally needs to be turned by 90° to flow from the first adapter 31 to the connecting portion 33, and the flow of the medium also needs to be turned by 90° to flow from the connecting portion 33 to the second adapter 32, and the arrangement of the flow guide segment 332 can reduce the angle of the flow path that needs to be changed by the medium, so that the flow of the medium is more smooth.
[0056] In the embodiment four, the ends of the first adapter 31 and the second adapter 32 away from the connecting portion 33 are also correspondingly arranged as a circular arc structure, and are respectively connected to the outer side walls of the first header 12 and the second header 22. Of course, the adapter seat 30 in the embodiment four can also be changed to be connected to the ends of the first header 12 and the second header 22, and is not limited to the above-mentioned limitation.
