[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Compared with the traditional solution of separating the compressor and the integrated module, the water cooling, chiller and compressor are integrated, and the liquid storage, refrigerant channel, various valves and sensors are integrated with the compressor, which reduces the number of parts and reduces the assembly workload, thereby reducing the cost of the whole machine; 2. Compared with the traditional cooling integrated module solution, the present invention integrates the air conditioning circuit and the coolant circuit, greatly reducing the number of water pipes and the difficulty of layout, thereby reducing the cost of the entire machine; 3.

[0016] See also Figure 1-10 The present invention provides a technical solution: a novel integrated structure of a thermal management system, including a cooling integrated module 300, wherein the cooling integrated module 300 includes a water jacket 200, wherein a compressor integrated module 100 is arranged in the water jacket 200, and wherein the cooling integrated module 300 also includes a water pump module, a sensor module and / or a valve module, wherein the water pump module, the sensor module and / or the valve module are connected via a cooling channel 301.

The chiller 101, the compressor 102, the water-cooled condenser 103 and the expansion valve 104 are connected in sequence. The compressor integrated module 100 adopts the reverse Carnot cycle principle. The compressor 102 compresses the low-temperature and low-pressure refrigerant from the chiller 101 into a high-temperature and high-pressure refrigerant that enters the water-cooled condenser 103 for cooling. The cooled medium-temperature and high-pressure refrigerant is expanded and then depressurized. In this process, the chiller 101 has a cooling and heat absorbing effect on the coolant, and the water-cooled condenser 103 has a heating and heating effect on the coolant.

[0018] In a specific embodiment of the present invention, the water pump module includes a first water pump 311 and / or a second water pump 312, the sensor module includes a first sensor 331, a second sensor 332 and / or a third sensor 333, and the valve module includes a first water valve 321, a second water valve 322 and / or a third water valve 323.

[0019] In a specific embodiment of the present invention, the water pump module further includes at least one backup water pump 313 , and the valve module further includes at least one backup water valve 324 and / or a one-way valve 341 .

[0020] In a specific embodiment of the present invention, a cooling flow channel plate is provided on the water jacket 200, and a plurality of device installation interfaces 201 for installing a water pump module, a sensor module or a valve module are provided on the cooling flow channel plate. The cooling flow channel plate can utilize the compressor bracket body or the compressor integrated fixed flow channel plate as the flow channel plate base to integrate the water valve or water pump or kettle or sensor, etc.

[0021] In a specific embodiment of the present invention, an external interface 202 is provided at the end of the cooling channel 301 , and the external interface 202 is connected to the external circuit 400 .

[0022] In a specific embodiment of the present invention, the external circuit 400 includes a passenger compartment refrigeration circuit 401 , a battery circuit 402 , a motor circuit 403 , a warm air circuit 404 and / or at least one backup circuit 405 .

[0025] In a specific embodiment of the present invention, a water bottle 351 is installed on one of the device mounting interfaces 201, which can be used for liquid storage in the coolant circuit, and the water bottle 351 can be connected to the cooling channel plate or the water jacket 200 for exhaust or liquid replenishment.

[0026] In the present invention, the thermal management integrated module 500 is integrated on the water jacket 200, and the first water pump 311 can pump the low-temperature coolant cooled in the chiller 101 to the passenger compartment refrigeration circuit 401 or the battery circuit 402 or the motor circuit 403 through the first water valve 321 and the second water valve 322, and detect the circuit water temperature through the second sensor 332. The system is replenished with water using a kettle 351 in the circuit to prevent the air inside from affecting the heat exchange performance of the cooling system; The second water pump 312 can send the high-temperature coolant heated in the water-cooled condenser 103 to the battery circuit 402 or the motor circuit 403 through the warm air circuit 404 and the second water valve 322, and then return to the second water pump 312 through the third water valve 323. The circuit temperature can be detected by the first sensor 331.

The coolant of chiller 101 passes through the first water valve 321, bypasses the passenger compartment cooling circuit 401, and then flows to the second water valve 322, the battery circuit 402 and the third water valve 323. It flows to the first water pump 311 through the second sensor 332 and then flows back to chiller 101. At the same time, the coolant of the water-cooled condenser 103 passes through the warm air circuit 404, the second water valve 322, the motor circuit 403, the third water valve 323 and the second water pump 312, and then passes through the first sensor 331 to detect the temperature and then returns to the water-cooled condenser 103. like Fig.10 As shown, the third thermal management circuit can be used for battery heating or passenger compartment heating. The coolant of chiller 101 passes through the first water valve 321, bypasses the passenger compartment refrigeration circuit 401, and then flows to the second water valve 322, the motor circuit 403 and the third water valve 323. It flows to the first water pump 311 through the second sensor 332 and then flows back to chiller 101. At the same time, the coolant of the water-cooled condenser 103 passes through the warm air circuit 404, the second water valve 322, the battery circuit 402, the third water valve 323 and the second water pump 312, and then passes through the first sensor 331 to detect the temperature and then returns to the water-cooled condenser 103.
