Specifically, for ease of understanding, the description is given in connection with the specific structure of the intermediate heat exchanger of the present utility model:

as shown in fig. 1 to 24, the intermediate heat exchanger includes a body 1, a pipe assembly and a pressure regulating valve, the body 1 has a first heat exchanging flow path and a second heat exchanging flow path, the refrigerant in the first heat exchanging flow path is heat-exchangeable with the refrigerant in the second heat exchanging flow path, the pipe assembly is provided on the body 1 and includes a first pipe 2, a second pipe 3, a third pipe 5 and a fourth pipe 4, the first pipe 2 and the second pipe 3 are connected at both ends of the first heat exchanging flow path, the first pipe 2 has a first interface 22 which is communicable and disconnected with a heat supply passage 202 and a second interface 21 which is communicable and disconnected with an inlet pipe of the compressor 300, the second pipe 3 has a third interface 31 which is communicable with the battery heat exchanger 10, the third pipe 5 and the fourth pipe 4 are connected at both ends of the second heat exchanging flow path, the third pipe 5 has a fourth interface 51 which is communicable with the battery heat exchanger 10, and the fourth pipe 4 has a fifth interface 41 which is communicable and disconnected with a cooling passage 102.

Thus, as shown in fig. 22 and 23, in the battery heating mode, the first port 22 is connected to the heat supply passage 202, the second port 21 is disconnected from the inlet pipe of the compressor 300, the high-temperature refrigerant discharged from the compressor 300 flows into the first heat exchange passage along the heat supply passage 202 through the first port 22, the refrigerant in the first heat exchange passage flows into the cooling passage of the battery heat exchanger 10 through the third port 31 to heat the battery, the heat-exchanged refrigerant flows into the second heat exchange passage through the fourth port 51, the refrigerant in the second heat exchange passage finally flows out to the cooling passage 102 through the fifth port 41, and the refrigerant in the cooling passage 102 can be merged with the refrigerant in the outdoor heat exchange passage 100 and flows into the air intake side of the compressor 300.

As shown in fig. 21 and 24, in the battery cooling mode, the first port 22 is disconnected from the heat supply channel 202, the second port 21 is connected to the inlet pipe of the compressor 300, the high-temperature refrigerant discharged from the compressor 300 is cooled by the indoor radiator 101 of the outdoor heat exchange channel 100 and becomes a low-temperature refrigerant, the low-temperature refrigerant flows into the second heat exchange channel along the cooling pipe through the fifth port 41, the refrigerant in the second heat exchange channel flows into the battery heat exchanger 10 through the fourth port 51 to cool the battery, the refrigerant after heat exchange flows into the first heat exchange channel through the third port 31, and the refrigerant in the first heat exchange channel flows into the inlet pipe of the compressor 300 through the second port 21.

It can be understood that, because the pipeline assembly is integrated with the body 1, the pressure regulating valve is directly arranged on the pipeline assembly, compared with the traditional thermal management system which is used for independently arranging the intermediate heat exchanger and the pressure regulating valve and connecting the intermediate heat exchanger and the pressure regulating valve through pipelines and the like, the body 1 of the intermediate heat exchanger is close to the pressure regulating valve, no connecting pipeline is required to be arranged, the system layout is simple, the problem that the flowing state of the refrigerant in the vapor-liquid two-phase state changes due to overlong flowing distance can be avoided, and the refrigerating effect is improved.
