[0023] Example 1 like Figures 1 to 3 As shown, the present invention provides a thermal management system, including a flow channel plate assembly 100, a kettle assembly 200, a water pump assembly, a cooler 300, and a heat exchanger 400. The flow channel plate assembly 100 has a low-temperature cooling flow channel, a high-temperature cooling flow channel and a battery cooling flow channel; The kettle assembly 200 is connected to the heat exchanger 400 through a high-temperature cooling channel, and the kettle assembly 200 is connected to the cooler 300 through a low-temperature cooling channel and a battery cooling channel. The water pump set is located in the high-temperature cooling channel and the battery cooling channel, and the water pump set is used to provide power for the circulation of the high-temperature cooling channel and the battery cooling channel.

[0024] In this embodiment, the thermal management system includes a flow channel plate assembly 100, a kettle assembly 200, a water pump assembly, a cooler 300, and a heat exchanger 400. The flow channel plate assembly 100 forms a low-temperature cooling flow channel, a high-temperature cooling flow channel, and a battery cooling flow channel. The kettle assembly 200 is connected to the heat exchanger 400 through the high-temperature cooling flow channel. The kettle assembly 200 is also connected to the cooler 300 through the low-temperature cooling flow channel and the battery cooling flow channel. This reduces the number of pipes used to connect the various components, thereby reducing production costs. Furthermore, since the various components are interconnected through the flow channel plate assembly 100, the space utilization of the engine compartment is effectively improved. The integration of the flow channel plate assembly 100 also makes it easier to troubleshoot in case of a fault, improving troubleshooting efficiency.

[0025] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the kettle set 200 includes a low-temperature kettle and a high-temperature kettle; The low-temperature vessel includes a first exhaust port 201 and a low-temperature liquid outlet 202. Both the first exhaust port 201 and the low-temperature liquid outlet 202 are connected to the low-temperature cooling system to form a low-temperature cooling circulation loop. The high-temperature vessel includes a second exhaust port 203 and a first high-temperature liquid outlet 101 in the high-temperature cooling channel. Both the second exhaust port 203 and the first high-temperature liquid outlet 101 are connected to the high-temperature cooling system to form a high-temperature cooling circulation loop.

[0026] In this embodiment, the low-temperature cooler is connected to the low-temperature cooling system through the first vent 201 and the low-temperature liquid outlet 202 to form a low-temperature cooling circulation loop. The high-temperature cooler is connected to the high-temperature cooling system through the second vent 203 and the first high-temperature liquid outlet 101 to form a high-temperature cooling circulation loop. The first vent 201 is connected to the water-cooled intercooler, and the low-temperature liquid outlet 202 is connected to the low-temperature water pump located outside the thermal management system to replenish the low-temperature cooling system with low-temperature coolant. The second vent 203 is connected to the engine's vent and the high-temperature radiator's vent, respectively. The first high-temperature liquid outlet 101 is connected to the engine's water inlet to replenish the engine with high-temperature coolant. This enables the thermal management system provided in this embodiment to circulate with the vehicle's low-temperature and high-temperature cooling systems.

[0027] Since the low-temperature tank is used to hold low-temperature coolant and the high-temperature tank is used to hold high-temperature coolant, the first vent 201 and the second vent 203 can discharge the gas generated by the evaporation of coolant in the low-temperature tank and the high-temperature tank from the tank body while the coolant is flowing, thereby preventing the water pump unit from sucking in gas and causing cavitation and idling. At the same time, the first vent 201 and the second vent 203 can also realize the circulation of coolant.

[0028] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the kettle set 200 also includes a battery-operated kettle; The battery cooling channel is provided with a battery outlet 102 and a battery return port 204. Both the battery outlet 102 and the battery return port 204 are connected to the battery cooling system to form a battery cooling circulation loop.

[0029] In this embodiment, the battery reservoir is used to hold battery coolant. The battery reservoir and battery cooling channels are connected to the battery cooling system through the battery outlet 102 and the battery return port 204 to form a battery cooling circulation loop. The battery outlet 102 is connected to the inlet of the battery cooling system to replenish the battery cooling system with battery coolant. The battery return port 204 is connected to the outlet of the battery cooling system to circulate the battery coolant back to the battery reservoir after reuse. This enables the thermal management system provided in this embodiment to achieve circulation between the battery cooling system and the vehicle's battery cooling system.

[0030] Of course, the heat exchanger group 200 in the thermal management system provided in this embodiment includes a low-temperature heat exchanger, a high-temperature heat exchanger, and a battery heat exchanger. The number of heat exchanger groups 200 can be increased according to the actual situation, including but not limited to three. At the same time, a maximum liquid level line and a minimum liquid level line are set in an easily observable position on the outside of the heat exchanger body. A liquid level sensor is also set accordingly. The liquid level sensor detects the liquid level of the coolant in the heat exchanger body to prevent it from falling below the minimum liquid level line or rising above the maximum liquid level line. Otherwise, an alarm will be triggered and a prompt will be displayed on the vehicle's instrument panel to avoid the inability to perform low-temperature cooling, high-temperature cooling, or battery cooling due to insufficient liquid.

[0031] Preferably, the low-temperature kettle, high-temperature kettle, and battery kettle are set up independently and are not connected to each other. The opening pressure of each kettle lid can be controlled independently, and the low-temperature cooling system, high-temperature cooling system, and battery cooling system can be accurately controlled according to the signal.

[0032] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the water pump set includes a first water pump 500 and a second water pump 501; The first water pump 500 is located in the battery cooling channel and is used to provide power for the battery cooling circulation loop. The second water pump 501 is located in the high-temperature cooling channel and is used to provide power for the high-temperature cooling circulation loop. The high-temperature cooling channel is also provided with a second high-temperature liquid outlet 103, which is connected to the high-pressure electric heater.

[0033] In this embodiment, the first water pump 500 provides power to the battery cooling circulation loop, and the second water pump 501 provides power to the high-temperature cooling circulation loop. Correspondingly, in addition to the thermal management system provided in this embodiment, a low-temperature water pump is also provided. That is, the low-temperature water pump is located outside the flow channel plate assembly 100. The low-temperature water pump provides power to the low-temperature cooling circulation loop, thereby enabling the thermal management system to connect with the low-temperature cooling system, the high-temperature cooling system, and the battery cooling system, so as to facilitate the circulation of coolant.

[0034] The high-temperature coolant can enter the high-pressure electric heater through the second high-temperature outlet 103 under the action of the second water pump 501, so that the high-pressure electric heater can operate quickly.

[0035] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the heat exchanger 400 is provided with a high-temperature liquid inlet 104, which is connected to the engine and is used to allow the high-temperature coolant flowing out of the engine to flow into the heat exchanger 400.

[0036] In this embodiment, the high-temperature inlet 104 is directly located in the heat exchanger 400. Of course, the high-temperature inlet 104 can also be located in the flow channel plate assembly 100 and connected to the heat exchanger 400 through the corresponding flow channel. The high-temperature inlet 104 is also connected to the engine, so that the high-temperature coolant flowing out of the engine can flow into the heat exchanger 400 for heat exchange. After heat exchange, it circulates through the high-temperature cooling flow channel and the high-temperature cooling system, which enables the high-temperature cooling system to utilize the waste heat generated by the engine to improve overall performance.

[0037] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the high-temperature cooling channel is also equipped with an air conditioning unit interface 105, and the cooler 300 is equipped with a refrigerant inlet 301 and a refrigerant outlet 302. The air conditioning unit interface 105 is connected to the air conditioning unit, and the air conditioning unit is connected to the high-temperature cooling system; The air conditioning pipeline is equipped with a first interface and a second interface. The refrigerant inlet 301 is connected to the first interface, and the refrigerant outlet 302 is connected to the second interface, forming an air conditioning cold air cooling circulation loop.

[0038] In this embodiment, the air conditioning box interface 105, which is provided through a high-temperature cooling channel, is connected to the air conditioning box, thereby enabling the high-temperature coolant in the thermal management system provided in this embodiment to flow into the air conditioning box, so that the air conditioning box can generate heat and blow out warm air. Of course, the air conditioning box is also connected to the high-temperature cooling system of the whole vehicle, so that the coolant after the air conditioning box is used continues to circulate in the high-temperature cooling system.

[0039] The cooler 300 is provided with a refrigerant inlet 301 and a refrigerant outlet 302. The refrigerant inlet 301 is connected to the first interface, and the refrigerant outlet 302 is connected to the second interface, thereby forming an air conditioning cold air cooling loop so that the car's air conditioning can blow out cold air. The refrigerant enters the cooler 300 through the refrigerant inlet 301 and exchanges heat with the low-temperature coolant flowing in the cooler 300. Then, it returns to the air conditioning pipe through the refrigerant outlet 302, so that the air conditioning can blow out cold air. The specific heat exchange and cooling process of the refrigerant is existing technology, so it will not be described in detail.

[0040] Among them, the first exhaust port 201, the low temperature liquid outlet 202, the second exhaust port 203, the first high temperature liquid outlet 101, the battery liquid outlet 102, the battery liquid return port 204, the second high temperature liquid outlet 103, the high temperature liquid inlet 104, and the air conditioning box interface 105 all adopt VDA quick connectors to facilitate production and pipeline assembly. The VDA quick connector is an existing technology and is a quick connector that conforms to the German automotive industry standard (VDA), so it will not be described in detail.

[0041] The refrigerant inlet 301 and refrigerant outlet 302 are designed with reference to automotive air conditioning pipe fittings and connectors. Preferably, the inner diameter of the refrigerant inlet 301 is 10.15±0.2mm and the inner diameter of the refrigerant outlet 302 is 15.5±0.2mm.

[0042] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the flow channel plate assembly 100 is also provided with a four-way valve 600. The four-way valve 600 has a first interface, a second interface, a third interface and a fourth interface. The first interface is connected to the air conditioning box interface 105, the second interface is connected to the second exhaust port 203, the third interface is connected to the second water pump 501, and the fourth interface is connected to the heat exchanger 400. When the four-way valve 600 is in the first working state, the first port and the fourth port are connected, and the second port and the third port are disconnected. When the four-way valve 600 is in the second working state, the first and second ports are connected, and the third and fourth ports are disconnected. When the four-way valve 600 is in the third working state, the first port is connected to the second port and the fourth port respectively, and the third port is disconnected. When the four-way valve 600 is in the fourth working state, the third and fourth ports are connected, while the first and second ports are disconnected. When the four-way valve 600 is in the fifth working state, the second and third ports are connected, and the first and fourth ports are disconnected. When the four-way valve 600 is in the sixth working state, the second port is connected to the third port and the fourth port respectively, and the first port is disconnected. When the four-way valve 600 is in the seventh working state, the second port and the third port are connected, and the first port and the fourth port are connected. When the four-way valve 600 is in its eighth working state, the first and second ports are connected, and the third and fourth ports are connected.

[0043] In this embodiment, the thermal management system can achieve eight different operating states in the vehicle environment by controlling the opening and closing of the four-way valve 600. In the first operating state, the first and fourth ports of the four-way valve 600 are connected, while the second and third ports are disconnected. In the high-temperature cooling system, high-temperature coolant flows out from the high-temperature expansion tank, passes through the engine, and flows into the thermal management system. It then enters the heat exchanger 400 through the high-temperature inlet 104 for heat exchange. Simultaneously, in the battery cooling channel, battery coolant flows out from the battery reservoir, passes through the first water pump 500 and the cooler 300 in sequence, and then enters the heat exchanger 400 to exchange heat with the high-temperature coolant. After heat exchange, the hot coolant passes through... The battery cooling system flows through the battery to raise its temperature. In the second operating state, the first and second ports of the four-way valve 600 are connected, while the third and fourth ports are disconnected. In the high-temperature cooling system, high-temperature coolant flows out from the high-temperature expansion tank, passes through the engine, and then flows into the thermal management system. The high-temperature coolant flows through the air conditioning unit interface 105 in the high-temperature cooling channel, heating the air and generating warm air, which is then blown out. After heating, the air returns to the engine through the high-temperature cooling system. In the third operating state, the first and second ports of the four-way valve 600 are connected to the fourth port, the third port is disconnected, and the first port is connected to both the second and fourth ports. After the hot coolant flows out of the engine, it flows into the thermal management system. One path leads to the heat exchanger 400 through the high-temperature inlet 104, where it exchanges heat with the low-temperature coolant in the battery cooling channel to heat the battery. The other path leads to the air conditioning unit through the air conditioning unit interface 105 in the high-temperature cooling channel to heat the air, providing warm air. This allows the engine to heat the battery while providing warm air. In the fourth operating state, the third and fourth interfaces of the four-way valve 600 are connected, while the first and second interfaces are disconnected. After the high-temperature coolant flows out of the thermal management system, it flows through the high-temperature cooling system, passes through the high-pressure electric heater, and then through the high-temperature... The liquid flows into the heat exchanger 400 through the inlet 104, where it exchanges heat with the low-temperature coolant in the battery cooling channel. This heats the battery through the battery cooling system, raising its temperature. The coolant then flows back to the battery reservoir through the battery cooling system, thus achieving PCT (high-voltage electric heater) heating of the battery. In the fifth working state, the second and third ports of the four-way valve 600 are connected, while the first and fourth ports are disconnected. The high-temperature coolant flows out of the thermal management system, passes through the high-temperature cooling system and the high-voltage electric heater, and then flows into the air conditioning unit to heat the air, enabling the air conditioning unit to provide warm air. The coolant then flows back to the thermal management system through the high-temperature cooling system, achieving PCT heating of warm air.In the sixth operating state, the second, third, and fourth ports of the four-way valve 600 are opened, the first port is disconnected, and the second port is connected to the third and fourth ports respectively. High-temperature coolant flows out of the thermal management system and through the high-temperature cooling system to the high-pressure electric heater. One path leads back to the thermal management system through the high-temperature inlet 104, where it exchanges heat with the low-temperature battery coolant in the heat exchanger 400, and then flows through the battery cooling channel and battery cooling system to heat the battery. Another path leads into the air conditioning unit through the air conditioning unit interface 105 to heat the air, and then back to the thermal management system through the high-temperature cooling system to heat the air, thus achieving simultaneous heating of the battery and the PCT heating the heater. In the seventh operating state, the first, second, third, and fourth ports of the four-way valve 600 are all opened, with the second and third ports connected and the first and fourth ports connected. The high-temperature coolant flowing from the engine carries the engine's heat... The heat generated by waste heat flows into the thermal management system through the high-temperature inlet 104, enters the heat exchanger 400 to exchange heat with the low-temperature battery coolant, and simultaneously, a portion of the high-temperature coolant enters the high-pressure electric heater through the second high-temperature outlet 103 to continuously provide the heat required for battery heating, thus achieving the purpose of heating the battery using engine waste heat. In the eighth working state, the first, second, third, and fourth ports of the four-way valve 600 are all opened, connecting the first and second ports and the third and fourth ports. The high-temperature coolant flowing out of the high-temperature expansion tank flows through the engine, and one path flows through the air conditioning unit, the first port, and the second port before returning to the engine to form a circulation loop. The other path flows through the high-temperature inlet 104 into the thermal management system, passes through the heat exchanger 400, the third port, the fourth port, and the second water pump 501, and then flows out of the thermal management system. After passing through the high-pressure electric heater, it merges with the first path to form a replenishment circulation for the high-temperature cooling system.

[0044] According to one embodiment of the present invention, the flow channel plate assembly 100 includes a front flow channel plate, a middle flow channel plate, and a rear flow channel plate; The front flow channel plate, middle flow channel plate, and rear flow channel plate are arranged at intervals; The low-temperature cooling channel is located on the front flow channel plate, the high-temperature cooling channel is located on the middle flow channel plate, and the battery cooling channel is located on the rear flow channel plate.

[0045] In this embodiment, the front flow channel plate, the middle flow channel plate, and the rear flow channel plate are independent flow channels and are fixed together by molten hot welding. The front flow channel plate is connected to the low temperature tank, that is, the front flow channel plate forms a low temperature cooling flow channel; the middle flow channel plate is connected to the high temperature tank, that is, the middle flow channel plate forms a high temperature cooling flow channel; and the rear flow channel plate is connected to the battery tank, that is, the rear flow channel plate forms a battery cooling flow channel.

[0046] By forming different cooling channels using different flow channels, it is possible to effectively avoid the situation where different cooling circuits share the same flow channel, thereby preventing the coolant from escaping heat within the flow channel and affecting the overall thermal management effect.

[0047] According to one embodiment of the present invention, a heat insulation layer is provided between the low-temperature kettle, the high-temperature kettle, and the battery kettle.

[0048] In this embodiment, since the low-temperature cooling channel, high-temperature cooling channel, and battery cooling channel are all formed by independent channel plates to prevent heat transfer, a heat insulation layer is provided between the different reservoir cavities to further reduce heat transfer between different coolants; that is, a heat insulation layer is provided between the low-temperature reservoir, the high-temperature reservoir, and the battery reservoir. The heat insulation layer needs to have the characteristics of high temperature resistance, flame retardancy, lightweight, and chemical stability. Therefore, the heat insulation layer can be made of materials such as aluminum foil composite heat insulation cotton, silicone foam material, or ceramic fiber paper.

[0049] When assembling the thermal management system provided in this embodiment, the low-temperature kettle is first assembled with the front flow channel plate, the high-temperature kettle with the middle flow channel plate, and the battery kettle with the rear flow channel plate. Then, the cooler 300 (the cooler 300 referred to here is the Chiller assembly, which is existing technology and will not be described in detail) is assembled into the reserved position of the flow channel plate assembly 100. Then, the first water pump 500, the four-way valve 600, the heat exchanger 400, and the second water pump 501 are respectively assembled into the flow channel plate assembly 100. The components assembled into the flow channel plate assembly 100 are internally connected through the low-temperature cooling flow channel, the high-temperature cooling flow channel, and the battery cooling flow channel formed in the flow channel plate assembly 100. Then, the wiring harness 701 is assembled, that is, the connectors of the first water pump 500, the second water pump 501, and the electronic expansion valve in the cooler 300 are inserted and fixed on the thermal management system to realize the circuit connection. Finally, the lids of the low-temperature kettle, the high-temperature kettle, and the battery kettle, as well as the shock-absorbing pads, are assembled. By integrating the flow channel plate assembly 100, the space utilization of the engine compartment is greatly improved, the number of pipes and joints is reduced, and the probability of coolant leakage is also reduced.

[0050] Preferably, the flow channel plate assembly 100 has reserved installation positions for corresponding components and has interfaces. After aligning the interfaces of the flow channel plate assembly 100 with the inlet and outlet of the corresponding components, it is fixed by bolts. The flow channel plate assembly 100 and the nut are injection molded as a whole. The embedded nut is made of steel. Each component can be disassembled individually for subsequent maintenance. The specific assembly method is existing technology and will not be described in detail here.

[0051] Example 2 The present invention provides an automobile including the above-described thermal management system.

[0052] In this embodiment, the vehicle includes the aforementioned thermal management system. By using the aforementioned thermal management system, the internal components can be integrated, reducing the piping used to connect the components, thereby reducing production costs, lowering the overall weight, and improving the lightweight effect of the vehicle. At the same time, it can also improve the space utilization rate inside the engine compartment. When the thermal management system malfunctions, it can be easily troubleshooted and the faulty component can be quickly identified.

[0053] Preferred, such as Figure 2 As shown, the thermal management system provided in this embodiment also includes a bracket, at least one of which can be provided. The specific number of brackets can be selected according to the corresponding vehicle model. Each bracket corresponds to one mounting point 700, which can be one, two, three, or more. When the number of mounting points 700 is greater than one, the mounting points 700 are distributed at intervals along the outer edge of the thermal management system, and the bracket is connected to the vehicle body through rubber pads. That is, rubber pads are fixed at the ends of the brackets, and then fixed to the vehicle body through fasteners to achieve a soft connection effect. At the same time, the rubber pads can also effectively reduce vibration and noise, significantly improving the driver's driving experience. The fixing methods of the brackets and rubber pads, and the fixing methods of the brackets and the vehicle body are existing technologies, and therefore will not be described in detail.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
