[0072] A twenty-fifth flow channel is arranged on the cooling liquid flow channel plate, one end of the twenty-fifth flow channel is in communication with the expansion water bottle outlet, and the other end is in communication with the second electronic water pump inlet.

[0073] Through mode switching of the nine-way valve 12, the first three-way proportional valve, and the second three-way valve 11, through four mode switching of the multi-way water valve, the system mode in the secondary circuit R290 system is switched, so that functions such as electric drive cooling, electric drive waste heat recovery, battery 21 cooling, battery 21 heating, passenger compartment cooling, passenger compartment heating, and passenger compartment initial heating are realized.

[0074] In the embodiment of the application, the battery 21 cooling and the passenger cabin refrigeration function are realized by the water-cooled evaporator 6. Since the battery 21 cooling and the passenger cabin refrigeration require different temperatures, generally, the battery 21 cooling is about 17-25 degrees, and the passenger cabin requires a temperature of about 0-10 degrees, and the realization of the control of the different temperatures of the two generally requires the use of two water-cooled evaporators 6 or two water pumps; however, this will cause the integrated module to be too large in size, which is difficult to arrange for a vehicle. Therefore, the system architecture used in the embodiment of the application is optimized, and the product design realizes the mixed water design, the principle of which is that the water-cooled evaporator 6 preferentially ensures the temperature of the component requiring a low temperature (generally, the cold air core 16 of the passenger cabin), and then is connected to the battery inlet E in bypass through the battery outlet F (the heated cooling liquid of the battery outlet F is mixed with the water of the battery inlet E which is low in temperature, so as to realize the control of the temperature of the battery inlet E), so as to realize the mixed water function of the battery 21 with a reduced number of components and a compact structure.

[0075] With reference to Figure 2 The cooling liquid flow channel plate further integrates a one-way valve 13, and the inlet and outlet of the one-way valve are connected to the thirteenth flow channel.

[0076] The heated cooling liquid of the battery outlet F returns to the battery inlet E through the thirteenth flow channel on the cooling liquid flow channel plate as a bypass, and the second three-way valve 11 adjusts the flow rate here, so as to realize the different temperature and flow rate requirements of the battery 21 and the passenger cabin, and only one water-cooled evaporator 6 is used.

[0077] With reference to Figure 2 The twenty-first flow channel and the twenty-fourth flow channel are connected to the high-temperature area of the expansion water tank 14, and the twenty-fifth flow channel is connected to the low-temperature area of the expansion water tank 14.

[0078] The twenty-first flow channel and the twenty-fourth flow channel form an exhaust air circuit of the high-temperature area of the expansion water tank 14, and the gas-liquid mixed anti-freezing liquid entering the expansion water tank 14 in bypass through the twenty-first flow channel is separated into gas and liquid due to gravity in the expansion water tank 14, and the flow rate of the bypass into the expansion water tank 14 can be adjusted through the twenty-fourth flow channel (about 30%±10% of the flow rate of the exhaust air circuit).

[0079] The twenty-fifth flow channel is only used for water replenishment to the cooling liquid circuit requiring refrigeration, so as to prevent the heat loss of the high-temperature and low-temperature cooling liquid inside the expansion water tank 14.

[0080] The cooling liquid side integrated assembly further comprises a first temperature sensor T1, a second temperature sensor T2, a third temperature sensor T3, a fourth temperature sensor T4, a fifth temperature sensor T5 and a sixth temperature sensor T6 integrated on the cooling liquid flow channel plate, the first temperature sensor T1 is connected to the eleventh flow channel, the second temperature sensor T2 is connected to the twelfth flow channel, the third temperature sensor T3 is connected to the eighth flow channel, the fourth temperature sensor T4 is connected to the ninth flow channel, the fifth temperature sensor T5 is connected to the fourteenth flow channel, and the sixth temperature sensor T6 is connected to the nineteenth flow channel.

[0081] It should be noted that each of the embodiments in the present specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be mutually referred to.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the present application.
