Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a thermal management system and a vehicle. Background Technology

[0002] The vehicle's thermal management system includes an air conditioning refrigerant circulation system and a coolant circulation system. The air conditioning refrigerant circulation system is used to regulate the temperature inside the vehicle's passenger compartment and the temperature of the vehicle's battery. The coolant circulation system is used to regulate the temperature of the vehicle's battery. The air conditioning refrigerant circulation system includes a compressor, condenser, evaporator, expansion valve, etc., while the coolant circulation system includes a PTC heater, water pump, radiator, etc. In summer, the PTC heater is turned off, and the coolant circulation system only circulates, thereby cooling the vehicle's battery. In winter, the PTC heater is turned on, thereby warming the vehicle's battery.

[0003] In the prior art, the compressor and PTC heater are respectively located in different positions on the vehicle. When the compressor and PTC heater are running, the temperature of the compressor controller in the compressor housing and the heating element controller in the PTC heater housing will rise, usually to about 100°C.

[0004] In the prior art, the compressor controller achieves cooling by exchanging heat between the compressor housing and the external ambient air, and the heating element controller achieves cooling by exchanging heat between the PTC heater housing and the external ambient air. This results in low heat dissipation efficiency for the compressor controller and the heating element controller, which can easily cause damage to the compressor controller and the heating element controller, and consequently cause the air conditioning refrigerant circulation system and the coolant circulation system to fail. Summary of the Invention

[0005] This application provides a thermal management system and a vehicle to solve the technical problem of low heat dissipation efficiency of the compressor controller and heating element controller in existing thermal management systems.

[0006] A first aspect of this application provides a thermal management system, including:

[0007] An air conditioning refrigerant circulation system includes a compressor, the compressor including a compressor housing and a compressor controller, the compressor housing including an inlet section and an installation section that are interconnected, the inlet section being used to contain refrigerant entering the compressor housing, and the installation section being used to install a refrigerant compression assembly;

[0008] A coolant circulation system includes a liquid heater, the liquid heater including a heater housing and a heating element controller, the heater housing containing coolant and a heating element for heating the coolant;

[0009] The controller housing contains both the compressor controller and the heating element controller. One end of the controller housing is connected to the air inlet section to allow heat exchange between the controller housing and the refrigerant within the air inlet section, thereby cooling the compressor controller and the heating element controller within the controller housing. The other end of the controller housing is connected to the heater housing to allow heat exchange between the controller housing and the heater housing, thereby cooling the compressor controller and the heating element controller within the controller housing.

[0010] In one possible implementation, the intake end section has a first opening at one end facing the controller housing, and the side wall of the controller housing facing the intake end section covers the first opening.

[0011] In one possible implementation, the controller housing has a second opening at one end facing the heater housing, and the side wall of the heater housing facing the controller housing covers the second opening.

[0012] In one possible implementation, a first heat-conducting layer is provided between the side of the compressor controller near the intake section and the controller housing, and / or between the side of the heating element controller near the intake section and the controller housing.

[0013] In one possible implementation, a second heat-conducting layer is provided between the side of the compressor controller near the heater housing and the controller housing, and / or between the side of the heating element controller near the heater housing and the controller housing.

[0014] In one possible implementation, the compressor housing further includes an outlet section disposed at one end of the mounting section opposite to the inlet section and communicating with the mounting section, the outlet section being used to contain the refrigerant compressed by the refrigerant compression assembly.

[0015] In one possible implementation, the air conditioning refrigerant circulation system further includes an expansion valve, a first heat exchanger, and a second heat exchanger. The outlet section is connected to one end of the first heat exchanger, the other end of the first heat exchanger is connected to one end of the second heat exchanger, and the other end of the second heat exchanger is connected to the inlet section through the expansion valve.

[0016] In one possible implementation, the coolant circulation system further includes a water pump and a radiator. The heater housing is provided with an inlet and an outlet. One end of the water pump is connected to the outlet, and the other end of the water pump is connected to one end of the radiator. The other end of the radiator is connected to the inlet.

[0017] In one possible implementation, the heater housing includes an inlet terminal housing and an outlet terminal housing that are interconnected, with the inlet located on the inlet terminal housing and the outlet located on the outlet terminal housing, and the controller housing connected to the inlet terminal housing.

[0018] In one possible implementation, both the first thermally conductive layer and the second thermally conductive layer are thermally conductive silicone grease layers.

[0019] In one possible implementation, a vehicle controller and a temperature sensor are also included, wherein the compressor, the water pump, and the temperature sensor are electrically connected to the vehicle controller, and the temperature sensor is used to detect the temperature inside the controller housing;

[0020] When the temperature inside the controller housing is lower than a preset temperature, the vehicle controller controls the compressor or the water pump to start, so as to circulate the refrigerant in the air conditioning refrigerant circulation system or the coolant in the coolant circulation system, in order to cool down the compressor controller and the heating element controller inside the controller housing.

[0021] When the temperature inside the controller housing is greater than or equal to the preset temperature, the vehicle controller controls the compressor and the water pump to start simultaneously, so as to circulate the refrigerant in the air conditioning refrigerant circulation system and the coolant in the coolant circulation system, thereby cooling the compressor controller and the heating element controller inside the controller housing.

[0022] A second aspect of this application provides a vehicle, including:

[0023] Vehicle body;

[0024] It also includes the thermal management system described in any one of the above, wherein the thermal management system is disposed on the vehicle body.

[0025] This application provides a thermal management system and a vehicle. The thermal management system houses both the compressor controller and the heating element controller within a controller housing, with one end of the controller housing connected to the intake section. Because the temperature of the refrigerant entering the compressor housing is typically between a few degrees and ten degrees Celsius during summer cooling and close to ambient temperature during winter heating, the temperature of the refrigerant entering the compressor housing is much lower than the operating temperatures of the compressor controller and heating element controller. This allows the refrigerant in the intake section to exchange heat with the compressor controller and heating element controller within the controller housing, simultaneously cooling both components. Since the refrigerant circulates in the air conditioning refrigerant circulation system, the refrigerant in the intake section continuously cools the compressor controller and heating element controller within the controller housing. The other end of the controller housing is connected to the heater housing because... The temperature of the heater housing typically does not exceed 60 degrees Celsius, meaning it is lower than the operating temperatures of the compressor controller and heating element controller. This allows the coolant in the heater housing to exchange heat with the compressor controller and heating element controller in the controller housing, simultaneously cooling both components. Furthermore, because the coolant circulates within the coolant circulation system, it continuously cools the compressor controller and heating element controller. This continuous cooling of the compressor controller and heating element controller through the refrigerant in the intake section and / or the coolant in the heater housing improves their heat dissipation efficiency, thereby extending their lifespan and ensuring the continuous and stable operation of the air conditioning refrigerant circulation system and coolant circulation system.

[0052] The vehicle's thermal management system includes an air conditioning refrigerant circulation system and a coolant circulation system. The air conditioning refrigerant circulation system is used to regulate the temperature inside the vehicle's passenger compartment and the temperature of the vehicle's battery. The coolant circulation system is used to regulate the temperature of the vehicle's battery. The air conditioning refrigerant circulation system includes a compressor, condenser, evaporator, expansion valve, etc., while the coolant circulation system includes a PTC heater, water pump, radiator, etc. In summer, the PTC heater is turned off, and the coolant circulation system only circulates, thereby cooling the vehicle's battery. In winter, the PTC heater is turned on, thereby warming the vehicle's battery.

[0053] In the prior art, the compressor and PTC heater are respectively located in different positions on the vehicle. When the compressor and PTC heater are running, the temperature of the compressor controller in the compressor housing and the heating element controller in the PTC heater housing will rise, usually to about 100°C.

[0054] In the prior art, the compressor controller achieves cooling by exchanging heat between the compressor housing and the external ambient air, and the heating element controller achieves cooling by exchanging heat between the PTC heater housing and the external ambient air. This results in low heat dissipation efficiency of the compressor controller and the heating element controller, which can easily cause damage to the compressor controller and the heating element controller, and consequently cause failure of the air conditioning refrigerant circulation system and the coolant circulation system.

[0055] To address the technical problem of low heat dissipation efficiency of compressor controllers and heating element controllers in existing thermal management systems, this application proposes a thermal management system and a vehicle. The thermal management system includes an air conditioning refrigerant circulation system, a coolant circulation system, and a controller housing. The air conditioning refrigerant circulation system includes a compressor, which comprises a compressor housing and a compressor controller. The compressor housing includes an inlet section and an mounting section that are interconnected. The inlet section contains refrigerant entering the compressor housing, and the mounting section contains a refrigerant compression assembly. The coolant circulation system includes a liquid heater, which comprises a heater housing and a heating element controller. The heater housing contains coolant and a heating element for heating the coolant. Both the compressor controller and the heating element controller are housed within the controller housing. One end of the controller housing is connected to the inlet section to allow heat exchange between the controller housing and the refrigerant within the inlet section, thereby cooling the compressor controller and heating element controller within the controller housing. The other end of the controller housing is connected to the heater housing to allow heat exchange between the controller housing and the heater housing, thereby cooling the compressor controller and heating element controller within the controller housing.

[0056] In the thermal management system of this application, both the compressor controller and the heating element controller are housed within the controller housing, with one end of the controller housing connected to the intake section. Since the temperature of the refrigerant entering the compressor housing is typically between a few degrees and ten degrees Celsius during summer cooling and close to ambient temperature during winter heating, the temperature of the refrigerant entering the compressor housing is much lower than the operating temperatures of the compressor controller and heating element controller. This allows the refrigerant in the intake section to exchange heat with the compressor controller and heating element controller within the controller housing, thus simultaneously cooling both the compressor controller and heating element controller. Because the refrigerant circulates within the air conditioning refrigerant circulation system, the refrigerant in the intake section continuously cools the compressor controller and heating element controller within the controller housing.

[0057] Furthermore, the other end of the controller housing is connected to the heater housing. Since the temperature of the heater housing typically does not exceed 60 degrees Celsius, meaning it is lower than the operating temperatures of the compressor controller and heating element controller, the coolant inside the heater housing can exchange heat with the compressor controller and heating element controller inside the controller housing. This achieves simultaneous cooling of the compressor controller and heating element controller within the controller housing. Because the coolant circulates in the coolant circulation system, the coolant inside the heater housing can continuously cool the compressor controller and heating element controller within the controller housing. Through the continuous cooling of the compressor controller and heating element controller within the controller housing by the refrigerant in the intake section and / or the coolant inside the heater housing, the heat dissipation efficiency of the compressor controller and heating element controller within the controller housing is improved, thereby extending the service life of the compressor controller and heating element controller and ensuring the continuous and stable operation of the air conditioning refrigerant circulation system and coolant circulation system.

[0058] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0060] In the embodiments of this application, reference is made to Figures 1 to 3As shown, an embodiment of this application provides a thermal management system, including an air conditioning refrigerant circulation system 100, a coolant circulation system 200, and a controller housing 300.

[0061] The air conditioning refrigerant circulation system 100 includes a compressor 110, which includes a compressor housing 111 and a compressor controller 112. The compressor housing 111 includes an inlet section 1111 and an installation section 1112 that are interconnected. The inlet section 1111 is used to contain refrigerant entering into the compressor housing 111, and the installation section 1112 is used to install a refrigerant compression assembly 113.

[0062] The coolant circulation system 200 includes a liquid heater 210, which includes a heater housing 211 and a heating element controller 212. The heater housing 211 contains coolant and a heating element 213 for heating the coolant.

[0063] Specifically, the liquid heater 210 can be a PTC heater, a resistance heater, an electric heating film, etc.

[0064] Both the compressor controller 112 and the heating element controller 212 are housed within the controller housing 300. One end of the controller housing 300 is connected to the inlet section 1111 to allow heat exchange between the controller housing 300 and the refrigerant within the inlet section 1111, thereby cooling the compressor controller 112 and the heating element controller 212 within the controller housing 300. The other end of the controller housing 300 is connected to the heater housing 211 to allow heat exchange between the controller housing 300 and the heater housing 211, thereby cooling the compressor controller 112 and the heating element controller 212 within the controller housing 300.

[0065] It should be noted that the controller housing 300 forms a cavity, and both the compressor controller 112 and the heating element controller 212 are housed within the cavity. The cavity formed by the controller housing 300 can be sealed or unsealed.

[0066] In the thermal management system of this application embodiment, the air conditioning refrigerant circulation system 100 can be used to regulate the temperature inside the passenger compartment of the vehicle and to regulate the temperature of the vehicle battery, and the coolant circulation system 200 can be used to regulate the temperature of the vehicle battery. Of course, the coolant circulation system 200 can also be used to regulate the temperature inside the passenger compartment of the vehicle.

[0067] The air conditioning refrigerant circulation system 100 includes a compressor 110, which includes a compressor housing 111 and a compressor controller 112. The compressor housing 111 includes an inlet section 1111 and an installation section 1112 that are connected to each other. An inlet port is provided on the inlet section 1111. The refrigerant in the air conditioning refrigerant circulation system 100 will enter the inlet section 1111 through the inlet port, so that the inlet section 1111 contains refrigerant. The installation section 1112 is connected to the inlet section 1111. A refrigerant compression assembly 113 is installed in the installation section 1112. The refrigerant in the inlet section 1111 will flow into the refrigerant compression assembly 113 in the installation section 1112 and be compressed by the refrigerant compression assembly 113 to form a high-temperature and high-pressure refrigerant. Finally, it will flow out from the compressor housing 111 to other components in the air conditioning refrigerant circulation system 100 for circulation.

[0068] The refrigerant compression assembly 113 includes a motor assembly 1131 and a moving and stationary disc assembly 1132.

[0069] It should be noted that when the air conditioning refrigerant circulation system 100 is cooling in summer, the temperature of the refrigerant entering the compressor housing 111 is usually between a few degrees and ten degrees Celsius, that is, the temperature of the refrigerant in the intake section 1111 is between a few degrees and ten degrees Celsius. When the air conditioning refrigerant circulation system 100 is heating in winter, the temperature of the refrigerant entering the compressor housing 111 is usually close to the ambient temperature, that is, the temperature of the refrigerant in the intake section 1111 is close to the ambient temperature. Therefore, it is much lower than the temperature of the compressor controller 112 and the heating element controller 212, which are close to 100 degrees Celsius during operation. This is because one end of the controller housing 300 is connected to the intake section 1111, which allows the refrigerant in the intake section 1111 to exchange heat with the compressor controller 112 and the heating element controller 212 in the controller housing 300, so that the refrigerant can cool down the compressor controller 112 and the heating element controller 212.

[0070] The coolant circulation system 200 includes a liquid heater 210, which includes a heater housing 211 and a heating element controller 212. The heater housing 211 is provided with an inlet and an outlet. The coolant in the coolant circulation system 200 enters the heater housing 211 through the inlet and is then heated by the heating element 213 inside the heater housing 211. The heated coolant flows into other components in the coolant circulation system 200 through the outlet for circulation. In summer, the heating element 213 is not turned on, meaning the coolant in the coolant circulation system 200 only circulates within the coolant circulation system 200 and is not heated by the heating element 213. At this time, the temperature of the heater housing 211 is close to or lower than the ambient temperature. In winter, the heating element 213 will be activated. At this time, the temperature of the heater housing 211 will not exceed 60°C due to the combined effect of the heating element 213 and the winter ambient temperature.

[0071] In other words, the temperature of the heater housing 211 is much lower than that of the compressor controller 112 and the heating element controller 212, which are close to 100°C during operation. This is because the other end of the controller housing 300 is connected to the heater housing 211, allowing the coolant in the heater housing 211 to exchange heat with the compressor controller 112 and the heating element controller 212 in the controller housing 300, thus cooling the compressor controller 112 and the heating element controller 212.

[0072] In the thermal management system of this application, both the compressor controller 112 and the heating element controller 212 are housed within the controller housing 300, and one end of the controller housing 300 is connected to the intake section 1111. Because the temperature of the refrigerant entering the compressor housing 111 is typically between a few degrees and ten degrees Celsius during summer cooling and close to ambient temperature during winter heating, the temperature of the refrigerant entering the compressor housing 111 is much lower than the temperatures of the compressor controller 112 and the heating element controller 212 during operation. Therefore, the intake section 111... The refrigerant in section 1111 can exchange heat with the compressor controller 112 and heating element controller 212 inside the controller housing 300, thus simultaneously cooling the compressor controller 112 and heating element controller 212 inside the controller housing 300. This is because the refrigerant circulates in the air conditioning refrigerant circulation system 100, meaning the refrigerant in the intake section 1111 can continuously cool the compressor controller 112 and heating element controller 212 inside the controller housing 300. Furthermore, the other end of the controller housing 300 is connected to the heater housing 211, because the temperature of the heater housing 211 is... The temperature typically does not exceed 60 degrees Celsius, meaning the temperature of the heater housing 211 is lower than that of the compressor controller 112 and heating element controller 212 during operation. This allows the coolant in the heater housing 211 to exchange heat with the compressor controller 112 and heating element controller 212 within the controller housing 300, thus simultaneously cooling both components. Because the coolant circulates in the coolant circulation system 200, the coolant in the heater housing 211 continuously cools the controller housing 300. The compressor controller 112 and heating element controller 212 inside the controller housing 300 are cooled by the refrigerant in the intake section 1111 and / or the coolant in the heater housing 211. This continuously cools the compressor controller 112 and heating element controller 212 inside the controller housing 300, improving the heat dissipation efficiency of the compressor controller 112 and heating element controller 212 inside the controller housing 300, thereby increasing the service life of the compressor controller 112 and heating element controller 212 and ensuring that the air conditioning refrigerant circulation system 100 and coolant circulation system 200 can work continuously and stably.

[0073] In another embodiment, reference is made to Figure 3 and Figure 4 As shown, the intake end section 1111 has a first opening 400 at one end facing the controller housing 300, and the side wall of the controller housing 300 facing the intake end section 1111 covers the first opening 400.

[0074] In this embodiment, the end of the air intake section 1111 facing the controller housing 300 is provided with a first opening 400, that is, the end face of the air intake section 1111 facing the controller housing 300 does not have a sidewall and is in an open state. The sidewall of the controller housing 300 facing the air intake section 1111 covers the first opening 400, that is, the sidewall of the controller housing 300 facing the end of the air intake section 1111 forms the sidewall of the first opening 400. In other words, the refrigerant in the air intake section 1111 is separated from the compressor controller 112 and the heating element controller 212 in the controller housing 300 by only one sidewall, thereby improving the heat exchange efficiency between the refrigerant in the air intake section 1111 and the compressor controller 112 and the heating element controller 212, that is, improving the cooling effect on the compressor controller 112 and the heating element controller 212.

[0075] In other embodiments, refer to Figure 4 and Figure 5 As shown, the controller housing 300 has a second opening 500 at one end facing the heater housing 211, and the side wall of the heater housing 211 facing the controller housing 300 covers the second opening 500.

[0076] In this embodiment, a second opening 500 is provided at one end of the controller housing 300 facing the heater housing 211. That is, the end face of the controller housing 300 facing the heater housing 211 does not have a sidewall and is in an open state. The sidewall of the heater housing 211 facing the controller housing 300 covers the first opening 400. That is, the sidewall of the heater housing 211 facing the controller housing 300 forms the sidewall of the first opening 400. In other words, the compressor controller 112 and the heating element controller 212 inside the controller housing 300 are separated from the coolant inside the heater housing 211 by only one sidewall, thereby improving the heat exchange efficiency between the coolant inside the heater housing 211 and the compressor controller 112 and the heating element controller 212, that is, improving the cooling effect on the compressor controller 112 and the heating element controller 212.

[0077] In one embodiment, a first heat-conducting layer is provided between the side of the compressor controller 112 near the air intake section 1111 and the controller housing 300, and / or between the side of the heating element controller 212 near the air intake section 1111 and the controller housing 300.

[0078] In this embodiment, by setting a first heat-conducting layer, the heat exchange efficiency between the refrigerant and the compressor controller 112 in the intake section 1111 is further improved, and / or, the heat exchange efficiency between the refrigerant and the heating element controller 212 in the intake section 1111 is improved.

[0079] In some embodiments, a second heat-conducting layer is provided between the side of the compressor controller 112 near the heater housing 211 and the controller housing 300, and / or between the side of the heating element controller 212 near the heater housing 211 and the controller housing 300.

[0080] In this embodiment, by providing a second heat-conducting layer, the heat exchange efficiency between the coolant in the heater housing 211 and the compressor controller 112 is further improved, and / or, the heat exchange efficiency between the coolant in the heater housing 211 and the heating element controller 212 is improved.

[0081] In one possible embodiment, refer to Figure 3 and Figure 4 As shown, the compressor housing 111 also includes an outlet section 1113, which is located at one end of the mounting section 1112 away from the inlet section 1111 and is connected to the mounting section 1112. The outlet section 1113 is used to contain the refrigerant compressed by the refrigerant compression assembly 113.

[0082] In this embodiment, the outlet section 1113 is located at the end of the mounting section 1112 away from the inlet section 1111, thereby avoiding the stability of the outlet section 1113 from significantly affecting the temperature of the inlet section 1111 and ensuring that the temperature of the inlet section 1111 is low. The outlet section 1113 is used to contain the refrigerant after being compressed by the refrigerant compression assembly 113. The refrigerant in the outlet section 1113 will eventually flow out of the compressor housing 111 and enter other components in the air conditioning refrigerant circulation system 100, such as the heat exchanger.

[0083] In some possible embodiments, refer to Figure 1 and Figure 2 As shown, the air conditioning refrigerant circulation system 100 also includes an expansion valve 120, a first heat exchanger 130 and a second heat exchanger 140. The outlet section 1113 is connected to one end of the first heat exchanger 130, and the other end of the first heat exchanger 130 is connected to one end of the second heat exchanger 140. The other end of the second heat exchanger 140 is connected to the inlet section 1111 through the expansion valve 120.

[0084] In this embodiment, the first heat exchanger 130 can be an evaporator or a condenser, and the second heat exchanger 140 can be a condenser or an evaporator.

[0085] When the air conditioning refrigerant circulation system 100 is working, the refrigerant entering the compressor 110 will first enter the intake section 1111, then enter the installation section 1112, be compressed by the refrigerant compression assembly 113, and flow into the outlet section 1113. The refrigerant in the outlet section 1113 will flow into the first heat exchanger 130 through the pipeline, then flow into the second heat exchanger 140, and finally the refrigerant flows into the intake section 1111 of the compressor 110 through the expansion valve 120, forming a refrigerant circulation.

[0086] In another possible embodiment, refer to Figure 1 and Figure 2 As shown, the coolant circulation system 200 also includes a water pump 220 and a radiator 230. The heater housing 211 is provided with an inlet 2111 and an outlet 2112. One end of the water pump 220 is connected to the outlet 2112, and the other end of the water pump 220 is connected to one end of the radiator 230. The other end of the radiator 230 is connected to the inlet 2111.

[0087] In this embodiment, when the coolant circulation system 200 is working, the coolant entering the heater housing 211 from the inlet 2111 is heated by the heating element 213 and flows out from the outlet 2112. The coolant flowing out from the outlet 2112 is connected to the water pump 220 through a pipeline. The water pump 220 is then connected to the radiator 230 through a pipeline. The radiator 230 cools the coolant and then it enters the heater housing 211 through the inlet 2111, forming a coolant circulation.

[0088] In one embodiment, the heater housing 211 includes an inlet terminal housing and an outlet terminal housing that are interconnected. The inlet 2111 is disposed on the inlet terminal housing, the outlet 2112 is disposed on the outlet terminal housing, and the controller housing 300 is connected to the inlet terminal housing.

[0089] In this embodiment, the controller housing 300 is connected to the water inlet terminal housing because the temperature of the water inlet 2111 of the heater housing 211 is lower than the temperature of the water outlet 2112. The water inlet 2111 is located on the water inlet terminal housing, and the water outlet 2112 is located on the water outlet terminal housing. This ensures that the compressor controller 112 and the heating element controller 212 inside the controller housing 300 exchange heat with the coolant that is not heated by the heating element 213, thereby further improving the cooling effect on the compressor controller 112 and the heating element controller 212.

[0090] Furthermore, refer to Figure 5As shown, the heater housing 211 includes an upper sub-housing 2113 and a lower sub-housing 2114 that are interconnected. The upper sub-housing 2113 and the lower sub-housing 2114 are connected to form a cavity, and the heating element 213 is disposed in the cavity.

[0091] In another embodiment, both the first thermally conductive layer and the second thermally conductive layer are thermally conductive silicone grease layers.

[0092] The first and second thermal conductive layers can be made of thermally conductive pads, thermally conductive phase change materials, thermally conductive films, thermally conductive gels, thermally conductive foams, etc. In this embodiment, both the first and second thermal conductive layers are thermally conductive silicone grease layers to improve the thermal conduction between the compressor controller 112 and the heating element controller 212 and the controller housing 300.

[0093] In some embodiments, reference is made to Figure 9 As shown, it also includes a vehicle controller 800 and a temperature sensor 900. The compressor 110, water pump 220 and temperature sensor 900 are electrically connected to the vehicle controller 800 respectively. The temperature sensor 900 is used to detect the temperature inside the controller housing 300.

[0094] When the temperature inside the controller housing 300 is lower than the preset temperature, the vehicle controller 800 controls the compressor 110 or the water pump 220 to start, so that the refrigerant in the air conditioning refrigerant circulation system 100 or the coolant in the coolant circulation system 200 circulates, so as to cool down the compressor controller 112 and the heating element controller 212 inside the controller housing 300.

[0095] When the temperature inside the controller housing 300 of the vehicle controller 800 is greater than or equal to the preset temperature, the compressor 110 and the water pump 220 are turned on simultaneously to circulate the refrigerant in the air conditioning refrigerant circulation system 100 and the coolant in the coolant circulation system 200, so as to cool down the compressor controller 112 and the heating element controller 212 inside the controller housing 300.

[0096] In this embodiment, the preset temperature can be set to 80°C. That is, when the temperature of the vehicle controller 800 inside the controller housing 300 is less than 80°C, that is, when the temperature of the compressor controller 112 and the heating element controller 212 is less than 80°C, only the compressor 110 can be turned on to circulate the refrigerant in the air conditioning refrigerant circulation system 100, or only the water pump 220 can be turned on to circulate the coolant in the coolant circulation system 200. This can save the vehicle's energy while ensuring that the temperature of the compressor controller 112 and the heating element controller 212 is kept within a safe range.

[0097] When the temperature of the vehicle controller 800 inside the controller housing 300 is greater than or equal to 80°C, that is, when the temperature of the compressor controller 112 and the heating element controller 212 is greater than or equal to 80°C, the compressor 110 and the water pump 220 are turned on simultaneously. This causes the refrigerant in the air conditioning refrigerant circulation system 100 to circulate and the coolant in the coolant circulation system 200 to circulate. By exchanging heat between the refrigerant and the coolant on the compressor controller 112 and the heating element controller 212, the cooling efficiency of the compressor controller 112 and the heating element controller 212 is improved, ensuring that the compressor controller 112 and the heating element controller 212 can be cooled down to a safe range quickly.

[0098] It should be noted that the preset temperature is set according to the specific tolerance temperature of the compressor controller 112 and the heating element controller 212, and no specific numerical limit is made in this embodiment.

[0099] Furthermore, refer to Figure 7 As shown, the controller housing 300 also includes a high-voltage connector 600 and a low-voltage connector 700. The high-voltage connector 600 is electrically connected to the compressor controller 112 and the heating element controller 212, respectively. The low-voltage connector 700 is electrically connected to the compressor controller 112 and the heating element controller 212, respectively. The vehicle battery transmits electrical energy to the compressor controller 112 and the heating element controller 212 through the high-voltage connector 600. The vehicle controller sends and receives signals to and from the compressor controller 112 and the heating element controller 212 through the low-voltage connector 700.

[0100] A second aspect of this application provides a vehicle, including a vehicle body and a thermal management system.

[0101] The thermal management system is installed on the vehicle body.

[0102] The vehicle in this embodiment is equipped with the thermal management system of this embodiment. The thermal management system houses both the compressor controller 112 and the heating element controller 212 within the controller housing 300, and connects one end of the controller housing 300 to the intake section 1111. Because the temperature of the refrigerant entering the compressor housing 111 is typically between a few degrees and ten degrees Celsius during summer cooling and close to the ambient temperature during winter heating, the temperature of the refrigerant entering the compressor housing 111 is much lower than the temperature of the compressor controller 112 and the heating element controller 212 during operation. Therefore, the refrigerant in the intake section 1111 can exchange heat with the compressor controller 112 and the heating element controller 212 within the controller housing 300, thereby simultaneously cooling the compressor controller 112 and the heating element controller 212 within the controller housing 300. Since the refrigerant circulates in the air conditioning refrigerant circulation system 100, the refrigerant in the intake section 1111 can continuously cool the compressor controller 112 and the heating element controller 212 within the controller housing 300.

[0103] Furthermore, the other end of the controller housing 300 is connected to the heater housing 211. Since the temperature of the heater housing 211 typically does not exceed 60 degrees Celsius, meaning its temperature is lower than that of the compressor controller 112 and heating element controller 212 during operation, the coolant inside the heater housing 211 can exchange heat with the compressor controller 112 and heating element controller 212 inside the controller housing 300. This achieves simultaneous cooling of the compressor controller 112 and heating element controller 212 within the controller housing 300, as the coolant circulates in the coolant circulation system 200. The coolant inside 11 can continuously cool the compressor controller 112 and heating element controller 212 inside the controller housing 300. The continuous cooling of the compressor controller 112 and heating element controller 212 inside the controller housing 300 by the refrigerant in the intake section 1111 and / or the coolant in the heater housing 211 improves the heat dissipation efficiency of the compressor controller 112 and heating element controller 212 inside the controller housing 300, thereby increasing the service life of the compressor controller 112 and heating element controller 212 and ensuring that the air conditioning refrigerant circulation system 100 and the coolant circulation system 200 can work continuously and stably.
