When a car battery discharges with a high current, a large amount of heat is generated inside the battery. During prolonged operation at high temperatures, power batteries not only pose a risk of burning electronic components, but also a safety hazard of spontaneous combustion of the vehicle.

[0003] Currently, the cooling control of power batteries is based on the air conditioning compressor, which has a complex structure and large size. It cannot match the battery temperature to the vehicle system for cooling, which can easily lead to waste of resources or poor cooling effect. Therefore, there is an urgent need for an integrated cooling unit that can be matched with the vehicle thermal management system. Utility Model Content

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, the integrated battery cooling device includes a housing 1. An electronic water pump 4 is fixedly connected to the bottom plate of the housing 1. The water inlet end of the electronic water pump 4 is connected to a water inlet pipe 2 through a first molded rubber tube 3. The water inlet pipe 2 is fixedly connected to the housing 1. The water outlet end of the electronic water pump 4 is connected to a plate heat exchanger 6 through a second molded rubber tube 5. The plate heat exchanger 6 is fixedly connected to the bottom plate of the housing 1. A controller 11 is fixedly connected to the side wall of the housing 1.

[0028] like Figure 2 As shown, the plate heat exchanger core 6-3 has a plate heat exchanger inlet 6-2, a plate heat exchanger outlet 6-1, and a refrigerant interface 6-4. The refrigerant interface 6-4 is fixedly connected to an electronic expansion valve 7, which is fixedly connected to a refrigerant pipe 10. This allows the refrigerant in the air conditioning system to enter the plate heat exchanger core 6-3 to exchange heat and cool the hot water. At the same time, the opening and closing degree of the electronic expansion valve 7 can be adjusted to match and distribute the normal refrigerant.

[0029] The refrigerant pipe 10 includes a low-pressure refrigerant pipe 10-1 and a high-pressure refrigerant pipe 10-2. The electronic expansion valve 7 has a low-pressure port and a high-pressure port. The low-pressure port of the electronic expansion valve 7 is connected to the low-pressure refrigerant pipe 10-1. The other end of the low-pressure refrigerant pipe 10-1 is fixedly connected to a low-pressure plate 10-3. A refrigerant temperature and pressure sensor 10-5 is fixedly connected to the side wall of the low-pressure refrigerant pipe 10-1, which can monitor the pressure and temperature of the refrigerant entering the unit, and thus provide feedback to the electronic expansion valve 7 for adjustment, affecting the heat exchange of the refrigerant with the water.

[0030] The high-pressure port of the electronic expansion valve 7 is connected to a refrigerant high-pressure pipe 10-2. The other end of the refrigerant high-pressure pipe 10-2 is fixedly connected to a high-pressure plate 10-4. The low-pressure plate 10-3 and the high-pressure plate 10-4 are respectively fixedly connected to the outer shell 1. The low-pressure plate 10-3 and the high-pressure plate 10-4 are connected in the refrigerant system pipeline of the whole vehicle.

[0031] The electronic expansion valve 7 and the refrigerant temperature and pressure sensor 10-5 are electrically connected to the controller 11.

[0032] The heat exchanger inlet 6-2 is connected to the third molding hose 5, and the heat exchanger outlet 6-1 is connected to the outlet pipe 9 through the third molding hose 8. The outlet pipe 9 is fixedly connected to the outer casing 1.

[0033] like Figure 3 As shown, the water inlet pipe 2 includes a water inlet connector 2-1, one end of which is fixedly connected to the water inlet aluminum pipe 2-4, and the other end of the water inlet aluminum pipe 2-4 is connected to the first molded rubber tube 3;

The water inlet connector 2-1 is connected to the vehicle battery / motor water cooling pipeline, and the water replenishment connector 2-2 is connected to the vehicle water reservoir to add coolant to the vehicle cooling system.

[0035] like Figure 4 As shown, the water outlet pipe 9 includes a water outlet connector 9-1, and a water outlet aluminum pipe 9-2 is fixedly connected to the water outlet connector 9-1. The other end of the water outlet aluminum pipe 9-2 is connected to the third molding rubber tube 8.

[0036] The water outlet connector 9-1 is fixedly connected to the outer casing 1, and the water outlet connector 9-1 is connected to the water cooling pipeline of the vehicle battery / motor.

[0037] An outlet water temperature sensor 9-3 is fixedly connected to the side wall of the outlet aluminum pipe 9-2. The outlet water temperature sensor 9-3 is electrically connected to the controller 11. The outlet water temperature sensor 9-3 is used to detect the temperature of the water leaving the unit.

[0038] An inlet water temperature sensor 2-5 is fixedly connected to the side wall of the inlet aluminum pipe 2-4. The inlet water temperature sensor 2-5 is electrically connected to the controller 11. The inlet water temperature sensor 2-5 is used to detect the temperature of the water entering the unit.

[0039] The first operating condition: When the battery / motor temperature is too high, the water cooling pipe carries away the heat from the battery / motor through water. Hot water enters the unit through the inlet connector 2-1. The inlet water temperature sensor 2-5 will detect that the water temperature is too high and send a feedback signal to the whole vehicle. The opening degree of the electronic expansion valve 7 increases, and the heat exchange performance of the plate heat exchanger 6 increases rapidly. The refrigerant flows into the unit through the refrigerant pipe 10, which quickly cools the hot water entering the plate heat exchanger 6. The cooled water enters the water cooling pipe through the outlet aluminum pipe 9-2 to cool the battery / motor again.

[0040] The second operating condition: When the battery / motor temperature is normal, water enters the unit through the water inlet connector 2-1. The inlet water temperature sensor 2-5 will monitor the temperature. If the feedback is normal, there is no need to cool down. The electronic expansion valve 7 is closed, and the refrigerant will not flow into the unit. No heat exchange is performed on the water circuit, so the energy of the whole vehicle will not be wasted.
