At the same time, the number of parts is reduced, and the cost is saved.

[0045] Please refer to Figure 1 The embodiment provides an automobile air conditioner heat exchange assembly, which comprises a heat exchange core 100, a refrigeration joint 200 and a heating joint 300. The heat exchange core 100 is provided with a heat exchange channel for refrigerant flow.

[0046] As described above, the working mode of the automobile air conditioner heat exchange assembly provided by the embodiment is as follows:

[0047] In the refrigeration mode, the refrigeration joint 200 is communicated with the heat exchange core 100, and the heat exchange core 100 and the heating joint 300 are disconnected at the same time, so as to avoid refrigerant leakage from the heating joint 300; similarly, in the heating mode, the heating joint 300 is communicated with the heat exchange core 100, and the heat exchange core 100 and the refrigeration joint 200 are disconnected at the same time, so as to avoid refrigerant leakage from the refrigeration joint 200.

Since the evaporator and the condenser are arranged in an integrated structure, compared with the traditional independent design of the evaporator and the condenser, the number is reduced, which is conducive to the miniaturization and lightweight design of the air conditioning system, and can reduce the part processing and manufacturing cost.

[0048] The following embodiments illustrate the detailed structure of the automobile air conditioner heat exchange assembly provided by the application.

[0049] In the embodiment, the heat exchange core 100 includes a first water chamber 110, a second water chamber 120, a first flat tube unit 130, and a second flat tube unit 140. The first water chamber 110 and the second water chamber 120 are arranged in opposite directions. The first water chamber 110 and the second water chamber 120 are arranged in parallel. The first water chamber 110 is provided with two independent first flow channels. Each of the first flow channels extends in the length direction of the first water chamber 110. That is, the two first flow channels are arranged in parallel. The second water chamber 120 is provided with a second flow channel. The first flat tube unit 130 and the second flat tube unit 140 are arranged between the first water chamber 110 and the second water chamber 120. One end of the first flat tube unit 130 and one end of the second flat tube unit 140 are connected to the two first flow channels of the first water chamber 110, respectively. The other end of the first flat tube unit 130 and the other end of the second flat tube unit 140 are connected to the second flow channel of the second water chamber 120. In this way, the two first flow channels, the tube cavities of the first flat tube unit 130, the tube cavities of the second flat tube unit 140, and the second flow channel cooperatively define a flow channel of the heat exchange core 100.

[0050] It should be understood that the first flat tube unit 130 and the second flat tube unit 140 each include a plurality of flat tubes. The plurality of flat tubes of the first flat tube unit 130 are arranged in parallel and spaced apart. The plurality of flat tubes of the second flat tube unit 140 are arranged in parallel and spaced apart. Through the cooperation of the first water chamber 110, the second water chamber 120, the first flat tube unit 130, and the second flat tube unit 140, the flow path of the refrigerant can be increased, the heat exchange area can be increased, and the heat exchange efficiency can be improved.

[0051] In the embodiment, the refrigeration joint 200 includes a refrigeration water inlet pipe 210, a refrigeration water outlet pipe 220, and a refrigeration mounting seat 230. One end of the refrigeration water inlet pipe 210 and one end of the refrigeration water outlet pipe 220 are connected to the two first flow channels, respectively.

Similarly, the heating joint 300 includes a heating water inlet pipe 310, a heating water outlet pipe 320, and a heating mounting seat 330. One end of the heating water inlet pipe 310 and one end of the heating water outlet pipe 320 are connected to the two first flow channels, respectively. The other end of the heating water inlet pipe 310 and the other end of the heating water outlet pipe 320 are mounted on the heating mounting seat 330. During assembly, the refrigeration joint 200 and the heating joint 300 are connected to the first water chamber 110. The refrigeration joint 200 and the heating joint 300 are arranged at the two ends of the first water chamber 110 in the length direction of the first water chamber 110. The positions of the refrigeration joint 200 and the heating joint 300 do not interfere with each other, which facilitates assembly. At the same time, the refrigeration joint 200 and the heating joint 300 are arranged at the two ends of the first water chamber 110. When the refrigerant flows in the first water chamber 110, the refrigerant is less likely to accumulate at the ends of the first water chamber 110. The circulation of the refrigerant is more smooth, which is beneficial to the operation of the air conditioning system.

[0052] In addition, by installing the refrigeration joint 200 and the heating joint 300 on the same side of the heat exchange core 100, the layout is facilitated, and the overall structure is more compact and small in size.

[0053] It should be understood that the refrigeration water inlet pipe 210, the refrigeration water outlet pipe 220, the heating water inlet pipe 310, and the heating water outlet pipe 320 can be connected to the first water chamber 110 by riveting, welding, or screwing, and a sealing element can be arranged between each pipe body and the first water chamber 110 to improve the sealing performance.

[0054] The flow path of the refrigerant in the refrigeration mode of the automobile air conditioner heat exchange assembly of the embodiment of the present application is described below.

[0055] The refrigerant enters the flow channel a of the two first flow channels from the refrigeration water inlet pipe 210, then enters the second flow channel from the first flat tube unit 130, and then flows into the flow channel b of the two first flow channels from the third flat tube unit, and finally flows out from the refrigeration water outlet pipe 220.

[0056] The flow path of the refrigerant in the heating mode of the automobile air conditioner heat exchange assembly of the embodiment of the present application is described below.

[0057] The refrigerant enters the flow channel a of the two first flow channels from the heating water inlet pipe 310, then enters the second flow channel from the first flat tube unit 130, and then flows into the flow channel b of the two first flow channels from the second flat tube unit 140, and finally flows out from the heating water outlet pipe 320.

[0058] The automobile air conditioner heat exchange assembly provided in the embodiment can not only realize the functions of the evaporator and the condenser, but also reduce the number of parts and the size, facilitate lightweight and small-size design, and reduce the assembly cost, by cooperation of the heat exchange core 100, the refrigeration joint 200, and the heating joint 300.
