[0091] And, the water-cooled condenser 102 is used to transfer the heat of the high-temperature and high-pressure refrigerant discharged by the compressor to the cooling liquid, the high-pressure liquid accumulator dryer 103 is used to dry and filter the refrigerant, and is also used to store and supply the liquid refrigerant in the system, the first intermediate heat exchanger 104 and the second intermediate heat exchanger 203 described below are used for secondary heat exchange between the high-temperature refrigerant side and the low-temperature refrigerant side to improve the heat exchange efficiency of the system. The first electronic expansion valve 105 and the second electronic expansion valve 204 described below are used to throttle the high-temperature and high-pressure refrigerant into low-temperature and low-pressure refrigerant wet steam.

[0092] In addition, as an exemplary structure, the specific arrangement of the flow-through channels in the first valve plate 101 can be seen in Figure 3 The refrigerant outlet of the water-cooled condenser 102 is connected to the inlet of the high-pressure liquid accumulator dryer 103 through the flow-through channel 1a, the outlet of the high-pressure liquid accumulator dryer 103 is connected to the refrigerant inlet of one of the heat exchange sides in the first intermediate heat exchanger 104 through the flow-through channel 1b, the refrigerant outlet of the heat exchange side is connected to the flow-through channel 1e, and the first refrigerant outlet 108 can be connected to the inlet of the compressor.

[0093] The first electronic expansion valve 105 is arranged at the flow-through channel 1d, one end of the flow-through channel 1d is connected to the first refrigerant inlet 107, which is generally connected to the refrigerant outlet of the external water-cooled condenser.

Further, as a preferred embodiment, the second refrigerant side module 2 of the present embodiment further comprises a second intermediate heat exchanger 203 integrated on the second valve plate 201.

[0098] The second intermediate heat exchanger 203 is in communication with the flow passage in the second valve plate 201, and is specifically located upstream of the high-pressure side of the second electronic expansion valve 204 and downstream of the double-fluid heat exchanger 202.

[0099] More specifically, the second valve plate 201 can be formed by casting, and the double-fluid heat exchanger 202, the second intermediate heat exchanger 203 and the second electronic expansion valve 204 can be products commonly used in existing vehicle thermal management systems. The double-fluid heat exchanger 202 is used to absorb heat from the cooling liquid through low-temperature and low-pressure refrigerant wet steam, and mainly cools the power battery pack in the vehicle. The double-fluid heat exchanger 202 and the second intermediate heat exchanger 203 can be bolted to the second valve plate 201, and the second electronic expansion valve 204 can be screwed to the second valve plate 201.

Simultaneously, a fourth refrigerant outlet 2012 is also provided on the second valve plate 201. This fourth refrigerant outlet 2012 is connected in parallel with the second refrigerant-side module connection port 2010 on the flow channel 2a. The second refrigerant-side module connection port 2010, as described above, is used to connect to the first refrigerant-side module connection port 109 in the second refrigerant-side module 1, while the fourth refrigerant outlet 2012 is used to connect to the refrigerant inlet of an external water-cooled condenser.

[0103] A portion of the refrigerant entering circulation channel 2b can enter the external evaporator through the second refrigerant outlet 208, and the refrigerant flowing out of the evaporator can return to the second valve plate 201 through the second refrigerant inlet 209 and enter circulation channel 2e. Another portion of the refrigerant entering circulation channel 2b enters the refrigerant inlet of the dual-fluid heat exchanger 202 after passing through the second electronic expansion valve 204 at circulation channel 2c. The refrigerant outlet of the dual-fluid heat exchanger 202 is connected to circulation channel 2d. Circulation channels 2d and 2e are connected in parallel to the refrigerant inlet on the other heat exchange side of the second intermediate heat exchanger 203, and the refrigerant outlet on this heat exchange side is connected to the third refrigerant outlet 2011 via circulation channel 2f. The third refrigerant outlet 2011 is connected to the compressor inlet.

[0104] It should be noted that, based on the arrangement of the flow channels within the second valve plate 201, the first refrigerant temperature sensor 205 is located at flow channel 2d to detect the refrigerant outlet temperature of the two-fluid heat exchanger 202. The second refrigerant temperature sensor 206 and the refrigerant pressure sensor 207 are located at flow channel 2f to detect the refrigerant temperature and pressure at the outlet of the second intermediate heat exchanger 203, and the refrigerant being detected is the refrigerant after secondary heat exchange in the second intermediate heat exchanger 203.

[0105] Still Figure 5 As shown, in this embodiment, the coolant inlet and outlet 2013 of the dual-fluid heat exchanger 202 are used for coolant to enter and exit the dual-fluid heat exchanger 202, so as to realize the heat exchange between coolant and refrigerant inside the dual-fluid heat exchanger 202. Besides being used to connect the two refrigerant-side modules, when a first refrigerant-side module 1 or a second refrigerant-side module 2 is separately provided, the aforementioned first refrigerant-side module connection port 109 or second refrigerant-side module connection port 2010 can also be used to connect other vehicle thermal management modules.

[0106] In the embodiment, based on the above introduction of the coolant side module, as an exemplary implementation form, as shown in Figure 7 and Figure 8 the first coolant side module 3 should at least include a first coolant plate 301, and a first coolant pump 302 and a first control valve assembly 303 arranged on the first coolant plate 301.

[0107] The first coolant plate 301 is internally provided with a flow channel for the flow of coolant, and the surface of the first coolant plate 301 is provided with a plurality of coolant inlets and outlets in communication with the internal flow channel, and the first coolant pump 302 and the first control valve assembly 303 are connected in the flow channel inside the first coolant plate 301. Furthermore, as a preferred implementation form, the first coolant side module 3 of the embodiment further includes a first expansion tank 304, which is also in communication with the flow channel inside the first coolant plate 301.

[0108] More specifically, similar to the first valve plate 101 and the second valve plate 201, the first coolant plate 301 can also be prepared by casting, and of course, in addition to casting, the first coolant plate 301 can also be prepared by machining and welding.
