[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0033] Reference below Figure 1-Figure 8 A cooling assembly 100 according to an embodiment of the present invention is described, a thermal management system including the cooling assembly 100 is provided, and a vehicle including the thermal management system is further provided.

[0034] Combination Figure 1-Figure 5As shown, the cooling assembly 100 includes: a shell 10, an electrical device 20 and a fan assembly 30. The electrical device 20 is arranged inside the shell 10, and the fan assembly 30 is also arranged inside the shell 10. The fan assembly 30 can drive air to flow toward the electrical device 20 to exchange heat with the electrical device 20 to achieve heat dissipation or heating of the electrical device 20.

[0035] like Figure 1 and Figure 2 As shown, an air inlet 11 and an air outlet 12 are provided on opposite sides of the housing 10. Specifically, the air inlet 11 and the air outlet 12 are arranged opposite to each other on the housing 10, so that air can flow into the housing 10 from the air inlet 11 and then flow out from the air outlet 12. The air can flow through the surface of the electrical component 20 in the housing 10, and the air exchanges heat with the electrical component 20 to achieve the purpose of heat dissipation or heating of the electrical component 20.

[0036] The air inlet 11 is selectively connected to the air conditioning system, the outside world and the heating circuit, and the air outlet 12 is connected to the outside world.

[0037] The air inlet 11 can be connected to the air conditioning system, and a heat exchange outlet is provided at the passenger compartment. The heat exchange airflow of the air conditioning system flows from the heat exchange outlet to the passenger compartment to cool or heat. Also, the heat exchange outlet of the passenger compartment is connected to the air inlet 11, and the heat exchange airflow of the air conditioning system can be divided into two parts, one part flows from the heat exchange outlet to the passenger compartment to cool or heat the passenger compartment; the other part of the airflow flows from the heat exchange outlet to the air inlet 11, and the heat exchange airflow can flow into the housing 10, and the heat exchange airflow exchanges heat with the electrical device 20, thereby achieving heat dissipation or heating of the electrical device 20.

[0038] Furthermore, the heat exchange outlet is provided with a heater core and an electric heater. The heat exchange airflow flowing out of the air conditioning system exchanges heat at the heater core and the electric heater, further increasing the temperature of the heat exchange airflow. This part of the heat exchange airflow can flow to the air inlet 11 to heat the electrical device 20. When the temperature is relatively low and the electrical device 20 needs to be heated, the air conditioner is heated and the heater core and the electric heater are turned on. After the heat exchange airflow flowing out of the air conditioning system passes through the heater core and the electric heater for heat exchange, it flows to the air inlet 11 and exchanges heat with the electrical device 20 in the housing 10 to heat the electrical device 20.

[0039] The air inlet 11 can also be connected to the outside world, and the outside air can enter the shell 10 from the air inlet 11. After the outside air flows into the shell 10, it flows through the outer surface of the electrical component 20, taking away the heat of the electrical component 20, thereby achieving heat dissipation for the electrical component 20.

[0040] The cooling assembly 100 further includes: an electrical device 20, the electrical device 20 is connected to the housing 10, a gap is provided between the outer wall of the electrical device 20 and the inner wall of the housing 10, and a heat exchange channel 13 is formed between the air inlet 11, the gap and the air outlet 12. Specifically, the electrical device 20 is connected to the housing 10 so that the electrical device is installed inside the housing 10. A gap is provided between the outer wall of the electrical device 20 and the inner wall of the housing 10, and a heat exchange channel 13 is formed between the air inlet 11, the gap and the air outlet 12. The airflow enters the heat exchange channel 13, flows through the outer surface of the electrical device 20, and can exchange heat with the electrical device 20 to dissipate heat or heat the electrical device 20.

[0041] The cooling assembly 100 further includes: a fan assembly 30, which is disposed on the inner wall of the housing 10. Driven by the fan assembly 30, air exchanges heat with the electrical device 20 in the heat exchange channel 13. Specifically, the fan assembly 30 includes: a motor and a fan 31. The motor drives the fan 31 to rotate, so as to drive the airflow entering the housing 10 to flow toward the electrical device 20, thereby increasing the flow rate of the airflow flowing through the outer surface of the electrical device 20, so as to improve the heat dissipation efficiency or heating efficiency of the electrical device 20.

[0042] After the airflow flows into the shell 10, the fan assembly 30 accelerates the flow of the airflow on the outer surface of the electrical device 20. The airflow flows through all parts of the electrical device 20 and exchanges heat with the airflow, effectively compensating for the local heat exchange blind area problem caused by the structure of the shell 10, and realizing synchronous heat dissipation or heating of various parts of the electrical device 20.

[0043] Thus, air can flow from the air conditioning system and the outside to the housing 10 to dissipate heat or heat the electrical components 20. Under the premise of consuming as little energy as possible, the heat dissipation and heating requirements of the electrical components 20 are met; the heat exchange efficiency of the electrical components 20 is improved, the dependence of air cooling on the ambient temperature is greatly reduced, the application range of the product is broadened, and the product competitiveness is improved.

In other words, the outer surface of the body is wrapped with the protective shell 21, and the protective shell 21 can protect the body from external corrosion. The protective shell 21 is connected to the inner wall of the housing 10 to fix the electrical device 20 in the housing 10 and maintain the structural stability of the electrical device 20.

[0045] The first direction and the second direction are arranged perpendicularly, and the second direction is the extending direction of the air inlet 11 and the air outlet 12 .

[0046] The first direction may be a height direction of the electrical device 20 , and the second direction may be a length direction of the electrical device 20 .

[0047] The third direction may be a width direction of the electrical device 20 .

[0048] The outer wall of the protective shell 21 is provided with a plurality of heat exchange teeth 22 arranged at intervals, and a heat exchange groove 23 is formed between any two adjacent heat exchange teeth 22. Specifically, the protective shell 21 includes: a plurality of outer walls, at least one of which is provided with a plurality of heat exchange teeth 22, such as Figure 2-Figure 8 As shown, a plurality of heat exchanging teeth 22 extend along a first direction, wherein a plurality of heat exchanging teeth 22 are arranged at intervals along a second direction, and another plurality of heat exchanging teeth 22 are arranged at intervals along a third direction.

[0049] In some embodiments, the two outer walls of the protective shell 21 that are arranged opposite to the air inlet 11 and the air outlet 12 are provided with a plurality of heat exchange teeth 22, and any one of the outer walls is provided with a plurality of heat exchange teeth 22, and the plurality of heat exchange teeth 22 are arranged at intervals. The plurality of heat exchange teeth 22 extend in the height direction and are arranged in the width direction. A heat exchange groove 23 is formed between any two adjacent heat exchange teeth 22, and the heat exchange groove 23 is recessed toward the inside of the electrical device 20, thereby increasing the contact area between the electrical device 20 and the airflow, so as to improve the heat dissipation efficiency or heating efficiency of the electrical device 20.

[0050] In some embodiments, two oppositely disposed outer walls of the protective shell 21 in the third direction are provided with a plurality of heat exchange teeth 22. A plurality of heat exchange teeth 22 are provided on any one of the outer walls, and the plurality of heat exchange teeth 22 are arranged at intervals. The plurality of heat exchange teeth 22 extend along the height direction on the outer wall, and the plurality of heat exchange teeth 22 are arranged along the length direction. A heat exchange groove 23 is formed between any two adjacent heat exchange teeth 22, and the heat exchange groove 23 is recessed toward the inside of the electrical device 20, thereby increasing the contact area between the electrical device 20 and the airflow, so as to improve the heat dissipation efficiency or heating efficiency of the electrical device 20.

[0051] In some other embodiments, the heat exchange teeth may extend along the third direction and be arranged along the first direction. Specifically, the two outer walls of the protective shell 21 that are arranged opposite to the air inlet 11 and the air outlet 12 are provided with a plurality of heat exchange teeth 22, and any one of the outer walls is provided with a plurality of heat exchange teeth 22, and the plurality of heat exchange teeth 22 are arranged at intervals. The plurality of heat exchange teeth 22 may extend along the width direction and be arranged at intervals along the height direction. A heat exchange groove 23 is formed between any two adjacent heat exchange teeth 22, and the heat exchange groove 23 is recessed toward the interior of the electrical device 20, thereby increasing the contact area between the electrical device 20 and the airflow, so as to improve the heat dissipation efficiency or heating efficiency of the electrical device 20.

[0052] like Figure 3-Figure 6As shown, a plurality of heat exchange teeth 22 are each provided with a plurality of through-flow holes 24, the plurality of through-flow holes 24 extend along the second direction and are arranged at intervals along the first direction, and the through-flow holes 24 connect two adjacent heat exchange grooves 23. Specifically, a plurality of heat exchange teeth 22 are provided on two oppositely arranged side walls along the width direction of the protective shell 21, and a plurality of through-flow holes 24 are provided on any heat exchange tooth 22, and the plurality of through-flow holes 24 are arranged at intervals on the heat exchange tooth 22, the extension direction of the through-flow holes 24 is the length direction, and the plurality of through-flow holes 24 are arranged at intervals along the height direction. The through-flow holes 24 connect two adjacent heat exchange grooves 23 of the heat exchange tooth 22, and the airflow in the heat exchange groove 23 can flow through the through-flow holes 24, and the through-flow holes 24 can increase the contact area between the airflow in the heat exchange channel 13 and the outer surface of the electrical device 20, so as to improve the heat exchange efficiency between the electrical device 20 and the airflow, thereby improving the heat dissipation or heating efficiency of the electrical device 20.

[0053] Combination Figure 8 As shown, in some embodiments, the apertures of the through-flow holes 24 on at least two adjacent heat exchange teeth 22 are inconsistent. That is, by making the apertures of the through-flow holes 24 on at least two adjacent heat exchange teeth 22 inconsistent, the airflow is horizontal wind when it flows into the housing 10; by setting the apertures of the through-flow holes 24 to be inconsistent, the horizontal wind can be converted into a turbulent state, thereby improving the heat exchange efficiency between the airflow and the electrical device 20.

[0054] In some embodiments, along the second direction, the apertures of the through-flow holes 24 on the plurality of heat exchange teeth 22 gradually increase. Specifically, the apertures of the through-flow holes 24 on the same heat exchange tooth 22 may be the same, and along the length direction of the electrical device 20, the apertures of the through-flow holes 24 on the plurality of heat exchange teeth 22 gradually increase.

[0055] The number of through-flow holes 24 on the plurality of heat exchange teeth 22 gradually decreases along the length direction of the electrical device 20. Specifically, if the aperture of the through-flow holes 24 on one of the heat exchange teeth 22 is larger than the aperture of the through-flow holes 24 on another heat exchange tooth 22, the number of through-flow holes 24 on one of the heat exchange teeth 22 is smaller than the number of through-flow holes 24 on another heat exchange tooth 22. By setting the apertures of the through-flow holes 24 on the plurality of heat exchange teeth 22 to be inconsistent and the number of through-flow holes 24 on the plurality of heat exchange teeth 22 to be inconsistent, the advection wind can be converted into a turbulent state, thereby improving the heat exchange efficiency between the airflow and the electrical device 20.

[0056] according to Figure 2-Figure 5As shown, the fan assembly 30 includes: a plurality of fans 31, and the plurality of fans 31 are respectively arranged on two inner walls of the housing 10 in the first direction. That is to say, the plurality of fans 31 are arranged relatively along the first direction, and the electrical device 20 is sandwiched between the plurality of fans 31 on the opposite surfaces, that is, the plurality of fans 31 are arranged relatively to a plurality of outer walls of the electrical device 20. After the airflow enters the housing 10, that is, after the airflow enters the heat exchange channel 13, the plurality of fans 31 drive the airflow to flow toward the electrical device 20, so that the airflow is in full contact with the outer surface of the electrical device 20, so that the airflow and the electrical device 20 are fully exchanged with heat, thereby improving the heat exchange efficiency between the electrical device 20 and the airflow.

[0057] The fan assembly 30 includes: a plurality of fans 31, and the plurality of fans 31 are respectively arranged on two inner walls of the housing 10 in the third direction. That is, the plurality of fans 31 are arranged relatively along the third direction, and the electrical device 20 is sandwiched between the plurality of fans 31 on the opposite surfaces, that is, the plurality of fans 31 are arranged relatively to a plurality of outer walls of the electrical device 20. After the airflow enters the housing 10, that is, after the airflow enters the heat exchange channel 13, the plurality of fans 31 drive the airflow to flow toward the electrical device 20, so that the airflow is in full contact with the outer surface of the electrical device 20, so that the airflow and the electrical device 20 are fully exchanged with heat, thereby improving the heat exchange efficiency between the electrical device 20 and the airflow.

[0058] After the airflow flows into the shell 10, multiple fans 31 in various directions promote the flow of airflow on the outer surface of the electrical device 20. Airflow flows through various parts of the electrical device 20 and exchanges heat with the airflow, effectively compensating for the local heat exchange blind area problem caused by the structure of the shell 10, and realizing synchronous heat dissipation or heating of various parts of the electrical device 20.

[0059] According to some embodiments of the present invention, the cooling assembly 100 further includes: a plurality of fixing members, one end of each of which is respectively connected to the plurality of outer walls of the electrical device 20, and the other end of each of which is respectively connected to the plurality of inner walls of the housing 10. Specifically, the outer wall of the electrical device 20 is connected to one end of the fixing member, and the other end of the fixing member is connected to the inner wall of the housing 10. There may be a plurality of fixing members, and the plurality of fixing members are connected between the inner wall of the housing 10 and the outer wall of the electrical device 20 to fix the electrical device 20 in the housing 10, so as to facilitate airflow to enter the housing 10 for heat exchange with the electrical device 20, thereby achieving heat dissipation or heating of the electrical device 20.

[0060] The thermal management system according to the second embodiment of the utility model includes: an air conditioning system; a cooling component 100, an air inlet 11 selectively connected to the air conditioning system and the outside, and an air outlet 12 connected to the outside.

[0061] The thermal management system further includes: a motor controller. The electrical device 20 may be an electrical component in the motor controller that needs to be cooled or heated.

[0062] The thermal management system also includes: a control valve, which includes: a first valve port, a second valve port and a third valve port, the first valve port is connected to the air conditioning system, the second valve port is connected to the outside, and the third valve port is connected to the air inlet 11.

[0063] When the control valve is connected to the second valve port and the third valve port, the outside is connected to the air inlet 11, and the air outlet 12 is connected to the outside. The outside air is introduced into the housing 10 to dissipate heat for the electrical device 20.

[0064] When the control valve is connected to the first valve port and the third valve port, the air conditioning system is connected to the air inlet 11, and the air outlet 12 is connected to the outside. The heat exchange airflow of the air conditioning system can flow from the air inlet 11 into the housing 10, and exchange heat in the heat exchange channel 13.

[0065] The five modes of the thermal management system are described below.

[0066] First mode:

[0067] That is, the single cooling mode. In a low temperature environment, when the low temperature air outside the vehicle can meet the heat dissipation requirements of the electrical device 20, the first mode is adopted. The control valve is connected to the third valve port and the third valve port, the outside of the vehicle is connected to the air inlet 11, and the air outlet 12 is connected to the outside of the vehicle.

[0068] The thermal management system includes: an air intake pipeline, and the low-temperature air outside the vehicle is filtered and circulated in the air intake pipeline. The low-temperature clean air in the air intake pipeline is introduced into the air inlet 11, and heat is exchanged with the electrical component 20 in the heat exchange channel 13. The low-temperature air cools the electrical component 20, thereby realizing the heat dissipation function of the electrical component 20.

[0069] This mode has the lowest energy consumption for the whole vehicle, and can meet the heat dissipation performance requirements of the electrical components 20 without additional air cooling. At the same time, waste heat can be utilized, and the heated air can be introduced into the intake manifold of the engine to increase the intake temperature in a low-temperature environment, thereby improving the combustion efficiency of the fuel.

[0070] Energy transfer path: low-temperature air from the outside enters the housing 10 and exchanges heat with the electrical device 20, the electrical device 20 exchanges heat with the low-temperature air, the low-temperature air transfers the heat to the intake manifold of the engine, and is finally discharged to the outside of the vehicle through the exhaust gas.

[0071] Second mode:

[0072] That is, the strong cooling mode. In this mode, the ambient temperature is relatively high, and the low-temperature clean air introduced into the air intake duct cannot meet the heat dissipation performance requirements. On the basis of introducing the low-temperature clean air into the air intake duct, the heat exchange airflow of the air conditioning system is introduced. The air inlet 11 is connected to the outside of the vehicle and the air conditioning system, and the air outlet 12 is connected to the outside.

[0073] The low-temperature air after the evaporator in the air conditioning system dissipates heat is introduced into the housing 10, and the electrical components 20 are cooled. The proportion of low-temperature air in the dual circuit is adjusted based on the heat dissipation performance requirements. The adjustment principle is: under the condition that the performance is met, as much air as possible is used to reduce the energy consumption of the compressor and increase the vehicle's cruising range; this mode has a low dependence on the environment.

[0074] Energy transfer path: the electrical device 20 transfers part of the heat to the low-temperature outside air from the intake pipe, which enters the engine to participate in combustion after heat exchange in the shell 10 and is finally discharged to the outside of the vehicle; the other part of the heat is transferred to the heat exchange airflow, which is discharged to the outside after heat exchange in the shell 10.

[0075] Third mode:

[0076] That is, the extremely fast cooling mode. In this mode, the ambient temperature is high, the heat dissipation demand of the electrical device 20 is high, and the air inlet 11 is only connected to the air conditioning system. The electrical device 20 is cooled by the heat exchange airflow (low temperature) of the air conditioning system. At this time, the cooling efficiency and performance are the highest, and the electrical device 20 can be cooled extremely fast. At this time, the compressor consumes a high power; this mode has the lowest dependence on the environment.

[0077] Energy transfer path: The heat exchange airflow enters the shell 10 and flows through the surface of the electrical device 20. The electrical device 20 transfers all the heat to the heat exchange airflow, which is discharged to the outside after heat exchange in the shell 10.

[0078] Fourth mode:

[0079] That is, the normal heating mode. In this mode, the performance of the electrical device 20 is reduced due to the low temperature, and there is a lower heating demand. The air inlet 11 can be connected to the air conditioning system, and the air outlet 12 is connected to the outside of the vehicle. The air conditioning system can absorb the waste heat of the engine, and the heat exchange airflow (warm air) of the air conditioning system is introduced into the housing 10 to heat the electrical device 20. The heat of this circuit is generated by the waste heat of the engine, and the single heat source does not consume additional energy of the entire vehicle. This mode has low dependence on the environment.

[0080] Energy transfer path: the waste heat of the engine is transferred to the heat exchange airflow, the heat exchange airflow flows into the shell 10, exchanges heat with the electrical device 20, and transfers the heat to the electrical device 20.

[0081] Fifth mode:

[0082] That is, the extreme heating mode.

[0083] In this mode, the performance of the electrical component 20 is reduced or it stops working due to low temperature, and there is a high heating demand. After the air-conditioning system absorbs the waste heat of the engine, the heat exchange airflow (warm air) of the air-conditioning system is heated by the dual heat sources of the warm air core and the electric heater. The heating rate and power are greatly improved, which can meet the rapid heating requirements of the electrical component 20.

[0084] The electric heater can be an air-heated PTC. The air-heated PTC adjusts the heating power based on the heating performance requirements, and the air-heated PTC heating consumes additional vehicle electricity. Under the condition that the performance is met, the engine waste heat is used as much as possible to reduce the energy consumption of the air-heated PTC and increase the vehicle's cruising range.

[0085] The vehicle according to the third aspect of the utility model includes: a thermal management system. By introducing the heat exchange airflow of the air conditioning system or the air outside the vehicle into the cooling component, the heat dissipation and heating requirements of the electrical device 20 are met under the premise of consuming as little energy as possible of the entire vehicle; the heat exchange efficiency of the electrical device 20 is improved, the dependence of the air cooling form on the ambient temperature is greatly reduced, the application range of the product is broadened, and the product competitiveness is improved.
