Specifically, when the number of the external connection ends of the double pipe heat exchanger 11 is plural, the number of the supporting members 12 is also plural, and one supporting member 12 is correspondingly provided between one external connection end and the base plate 20. For example, when the spigot of the double pipe heat exchanger 11 is two, the number of the support members 12 is also two, one support member 12 is connected between one spigot and the base plate 20, and the other support member 12 is connected between the other spigot and the base plate 20.

Conceivably, the refrigerant inlet end, the refrigerant outlet end, the water inlet end and the water outlet end of the double-pipe heat exchanger 11 need to be correspondingly arranged according to an actual pipeline, that is, when the distances between the two external connection ends and the chassis 20 are different, the structures of the corresponding supporting members 12 can be adaptively adjusted, for example, the heights of the two supporting members 12 are different, so as to meet the connection requirements of the external connection ends at different positions.

Further, as shown in fig. 2, 3 and 4, the support member 12 includes a first connection member 121 and a second connection member 122, and the first connection member 121 is provided on the double pipe heat exchanger 11.

When the external terminals of the double-pipe heat exchanger 11 are the water inlet terminal and the water outlet terminal, the number of the supporting members 12 is two, and correspondingly, the number of the first connecting members 121 and the number of the second connecting members 122 are also two, one first connecting member 121 is disposed at the water inlet terminal, and the other first connecting member 121 is disposed at the water outlet terminal.

Further, the second connector 122 is detachably connected to the base plate 20, and the second connector 122 and the first connector 121 are detachably connected, so that the difficulty of assembling the support 12 between the double pipe heat exchanger 11 and the base plate 20 is reduced, and a plurality of assembling possibilities are provided. For example, during the assembly process of the supporting member 12, the first connecting member 121 may be connected to the external terminal of the double pipe heat exchanger 11, the second connecting member 122 may be connected to the base plate 20, and finally the first connecting member 121 and the second connecting member 122 may be assembled. Alternatively, after the first connector 121 is connected to the double pipe heat exchanger 11, the second connector 122 is connected to the first connector 121, and then the second connector 122 is assembled to the base pan 20.

Further, as shown in fig. 2, the first connector 121 is welded to the double pipe heat exchanger 11.

In this embodiment, the first connecting member 121 is a metal member, and the first connecting member 121 can be welded to the external terminal of the double-pipe heat exchanger 11, so that the connection manner is simple and the reliability is high. Meanwhile, the structure of the double-pipe heat exchanger 11 does not need to be changed, that is, the double-pipe heat exchanger 11 can adopt the original design/standard component and the like, and does not need to be changed in order to realize the matching with the first connecting piece 121, so that the production cost of the product is reduced.

In this embodiment, the support 12 further includes a first connection hole 123, the first connection hole 123 is disposed on the second connection member 122, specifically, the first connection hole 123 is disposed on the top of the second connection member 122, a screw hole is disposed on the first connection member 121 corresponding to the first connection hole 123, the first connection hole 123 extends vertically, that is, the first connection hole 123 has a certain length in the up-down direction, specifically, the first connection hole 123 includes an upper opening hole and a lower opening hole which are communicated with each other, and a first fastener passes through the first connection hole 123 and the screw hole, so that the detachable connection between the first connection member 121 and the second connection member 122 can be realized.

Because the double-pipe heat exchanger 11 may have machining deviation during machining, that is, the position of the external connection end of the double-pipe heat exchanger 11 is not unique, and different operators may have deviation during machining. For example, the outer terminal is slightly higher and lower than the standard height. In this case, the first fastening member may be selectively inserted into the upper opening or the lower opening according to the actual height of the outer connection end, that is, the first connection hole 123 may provide an installation margin in the vertical direction, may allow an installation deviation in the vertical direction, may allow the flexible assembly of the support member 12, and may reduce the installation difficulty of the support member 12 between the double pipe heat exchanger 11 and the base plate 20.

Further, as shown in fig. 3 and 4, the supporting member 12 further includes a second connecting hole 124, the second connecting hole 124 is opened on the second connecting member 122, and the second connecting hole 124 extends in a horizontal direction.

Similarly, since the double pipe heat exchanger 11 may be manufactured with a deviation, that is, the external connection end of the double pipe heat exchanger 11 is not uniquely located, different operators may have a deviation during the manufacturing process. For example, the outer ends are slightly to the left, slightly to the right, slightly to the front, and slightly to the back of the standard position. In this case, the second fastening member can be selectively inserted into the left opening, the right opening, the front opening, and the rear opening, depending on the actual position of the outer joint end. That is, the second connection hole 124 can provide an installation margin in the horizontal direction, can tolerate an installation deviation in the horizontal direction, enables the support member 12 to achieve flexible assembly, and reduces the installation difficulty of the support member 12 between the double pipe heat exchanger 11 and the base plate 20.
