[0041] Reference below Figures 1 - 13 A thermal management system 100 for a vehicle according to an embodiment of the present invention is described.

[0042] like Figure 1 As shown, a thermal management system 100 for a vehicle according to an embodiment of the present invention includes: a motor heat exchange circuit 1 , a power battery heat exchange circuit 2 and an adjustable radiator 3 .

[0043] That is to say, the thermal management system 100 of the vehicle of the present invention is provided with a motor heat exchange circuit 1, a power battery heat exchange circuit 2 and an adjustable radiator 3 at the same time. Figure 1 As shown, the motor heat exchange circuit 1 is connected in series with motor elements, electronic control elements and charging and distribution elements, so that the motor heat exchange circuit 1 is suitable for dissipating the heat of the motor elements, electronic control elements and charging and distribution elements, and exporting the heat generated by the equipment elements in the circuit during operation. The power battery heat exchange circuit 2 is connected in series with a power battery, and the power battery heat exchange circuit 2 is suitable for dissipating the heat of the power battery and exporting the heat generated by the power battery during operation.

[0044] Among them, the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 can be selectively connected. That is to say, according to actual usage requirements, the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 can be controlled to be connected or not connected, so that the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 can be operated separately or mixed, which is convenient for selecting different working modes for different temperature environments, and when the two circuits are connected, the heat exchange medium can be shared, which is conducive to reducing the number of other components and reducing layout costs.

[0045] like Figure 1 As shown, the adjustable radiator 3 includes a first side heat exchange channel 31 connected in series to the motor heat exchange loop 1 and a second side heat exchange channel 32 connected in series to the power battery heat exchange loop 2. That is to say, the adjustable radiator 3 is installed between the motor heat exchange loop 1 and the power battery heat exchange loop 2. The motor heat exchange loop 1 is connected to the first side heat exchange channel 31, so that when the heat exchange medium in the motor heat exchange loop 1 flows to the first side heat exchange channel 31, heat is exchanged through the adjustable radiator 3. The power battery heat exchange loop 2 is connected to the second side heat exchange channel 32, so that when the heat exchange medium in the power battery heat exchange loop 2 flows to the second side heat exchange channel 32, heat is exchanged through the adjustable radiator 3. Therefore, it is convenient for the adjustable radiator 3 to dissipate heat for the motor heat exchange loop 1, and also for the power battery heat exchange loop 2, which is beneficial to reduce the number of other components, and does not need to set a separate heat dissipation structure in each heat exchange loop, thereby reducing the difficulty of design and layout and reducing installation costs.

[0046] The thermal management system 100 of the vehicle according to the present invention is provided with an adjustable radiator 3. Compared with the existing technologies (most of which use the air conditioning system for refrigeration to cool the power battery, or need to newly develop a complete set of heat dissipation circulation system to cool the power battery), it can reduce the number of multi-way valves under low-temperature working conditions, reduce costs and layout difficulties. Especially under the normal temperature working conditions of the environment of 10°C to 30°C, natural wind cooling is adopted for the power battery pack, without the need for secondary heat exchange by air conditioning refrigeration, and there is no need to design an additional heat dissipation circuit, which greatly reduces the energy consumption level during normal driving.

[0047] Among them, the adjustable radiator 3 selectively connects the motor heat exchange circuit 1 and the power battery heat exchange circuit 2. When the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 are connected through the adjustable radiator 3, the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 form a complete circulation circuit, and the heat in the motor heat exchange circuit 1 can be transferred to the power battery heat exchange circuit 2 to be used for heating the power battery, so that the thermal management system 100 of the vehicle has a mode of heating the power battery by the motor. In this mode, the power battery heat exchange circuit 2 absorbs the waste heat temperature of the motor heat exchange circuit 1 to provide heat absorption for the battery, so that the waste heat of the motor heat exchange circuit 1 can be fully recovered and utilized, which is beneficial to reducing energy consumption.

[0048] Among them, the heat dissipation area of the adjustable radiator 3 in the first-side heat exchange flow channel 31 and the second-side heat exchange flow channel 32 is adjustable. In this way, when the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 are dissipated heat through the adjustable radiator 3, the cooling effect of the adjustable radiator 3 can be flexibly adjusted. In this way, when the two heat exchange circuits have different heat dissipation requirements, the cooling effect of the adjustable radiator 3 at the first-side heat exchange flow channel 31 and the second-side heat exchange flow channel 32 can be flexibly adjusted by adjusting the heat dissipation area on both sides of the adjustable radiator 3, so as to well match the cooling requirements in the two heat exchange circuits. Therefore, through the adjustable radiator 3, the cooling requirements in different working modes can be met, which is beneficial to enriching the working modes of the thermal management system and expanding the application range of the thermal management system.

[0049] The thermal management system 100 of the vehicle according to the embodiment of the present invention can select different working modes according to different temperature environments, which is convenient for realizing the full utilization of the vehicle energy, reducing the energy consumption level, and adopting the adjustable radiator 3, without the need to set a separate radiator for each heat exchange circuit, reducing the design and layout difficulty, thereby reducing the production cost and expanding the application range of the thermal management system 100 of the vehicle.

[0050] In some embodiments, the adjustable radiator 3 includes a main body part and two connecting water chambers 33. It can be understood that, as Figure 2As shown, there are two connecting water chambers 33, and the two connecting water chambers 33 have the same size and structure. The upper end surfaces of the two connecting water chambers 33 are flush with the upper end surface of the main body part, and the lower end surfaces of the two connecting water chambers 33 are flush with the lower end surface of the main body part, which is easy to design and install. The main body part is provided with a plurality of micro heat exchange channels, and there is a heat exchange medium in the micro heat exchange channels, which is convenient for improving the heat dissipation efficiency of the adjustable radiator 3. Moreover, the sizes of the plurality of micro heat exchange channels are the same, which can adjust the heat dissipation areas of the two parts, and is convenient for the adjustable radiator 3 to dissipate heat evenly, and can reduce the design and layout difficulty of the micro heat exchange channels.

[0051] The two connecting water chambers 33 are respectively installed at both ends of the main body part and are connected through the micro heat exchange channels. That is to say, a plurality of micro heat exchange channels are all connected to the two connecting water chambers 33, and the connecting water chambers 33 are provided with a first pipe interface 31a and a second pipe interface 32a, as Figure 2 shown. The first pipe interface 31a and the second pipe interface 32a are respectively located on the first side and the second side of the main body part. The first pipe interface 31a can be set to two, and the two first pipe interfaces 31a can be connected through a part of the micro heat exchange channels of the main body part. The second pipe interface 32a can also be set to two, and the two second pipe interfaces 32a can be connected through another part of the micro heat exchange channels of the main body part. Moreover, each connecting water chamber 33 is provided with a first pipe interface 31a and a second pipe interface 32a, which is convenient for forming two heat exchange flow paths, so as to dissipate heat from the motor heat exchange circuit 1 and the power battery heat exchange circuit 2.

[0052] As Figure 2 shown, the two first pipe interfaces 31a of the two connecting water chambers 33 form two ports of the first side heat exchange flow path 31, and the two second pipe interfaces 32a of the two connecting water chambers 33 form two ports of the second side heat exchange flow path 32. That is to say, the plurality of micro heat exchange channels between the two first pipe interfaces 31a jointly form the first side heat exchange flow path 31, and the plurality of micro heat exchange channels between the two second pipe interfaces 32a jointly form the second side heat exchange flow path 32. Among them, the first side heat exchange flow path 31 can be connected to the motor heat exchange circuit 1, and the second side heat exchange flow path 32 can be connected to the power battery heat exchange circuit 2. That is to say, the first side heat exchange flow path 31 can be used to dissipate heat from the motor heat exchange circuit 1, and the second side heat exchange flow path 32 can be used to dissipate heat from the power battery heat exchange circuit 2. Thus, the adjustable radiator 3 can dissipate heat from the two circuits separately at the same time, and can provide the way of natural air cooling for the power battery under normal working conditions, which is beneficial to reducing energy consumption, and is convenient for reducing the number of radiators and the heat dissipation cost of the circuit.

[0053] As Figure 2As shown, two connecting water chambers 33 are respectively arranged at the left and right ends of the adjustable radiator 3. The first side heat exchange flow channels 31 and the second side heat exchange flow channels 32 are located between the two connecting water chambers 33, and the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32 can be selectively communicated through the two connecting water chambers 33, which is beneficial to adjusting the heat dissipation area in the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32 through the connecting water chambers, so as to flexibly adjust the cooling effect of the adjustable radiator 3 at the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32, and facilitate better matching of the cooling requirements in the motor heat exchange loop 1 and the power battery heat exchange loop 2.

[0054] In some embodiments, such as Figure 2 As shown, an adjusting component 331 is arranged in the connecting water chamber 33. The adjusting component 331 is used to separate the connecting water chamber 33 and multiple micro heat exchange channels into the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32, and the adjusting component 331 is used to adjust the heat dissipation area in the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32. That is to say, through the adjusting component 331, multiple micro heat exchange channels can be separated into two groups of micro heat exchange channels, and the two groups of micro heat exchange channels respectively form the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32, so as to facilitate heat dissipation for the motor heat exchange loop 1 and the power battery heat exchange loop 2 at the same time. At the same time, it should be noted that the total number of micro heat exchange channels in the main body part is a fixed value. That is to say, the sum of the number of micro heat exchange channels in the first side heat exchange flow channels 31 and the number of micro heat exchange channels in the second side heat exchange flow channels 32 is the total number of micro heat exchange channels. When the adjusting component 331 separates multiple micro heat exchange channels into the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32, there is a relationship of this increase and that decrease between the number of micro heat exchange channels in the first side heat exchange flow channels 31 and the number of micro heat exchange channels in the second side heat exchange flow channels 32, so as to realize the function of the adjusting component 331 to adjust the heat dissipation area in the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32, which is beneficial to flexibly adjusting the cooling effect of the adjustable radiator 3 at the first side heat exchange flow channels 31 and the second side heat exchange flow channels 32, and facilitating better matching of the cooling requirements in the motor heat exchange loop 1 and the power battery heat exchange loop 2.

[0055] When the adjustable radiator 3 is used to dissipate heat from the motor and the power battery, according to the actual heat dissipation temperature required by the motor and the power battery, the heat dissipation area of the second side heat exchange flow channels 32 is adjusted through the adjusting component 331, which is convenient for reasonably distributing the heat dissipation efficiency of the adjustable radiator 3, so as to reasonably control the heat dissipation amount of the adjustable radiator 3 for the motor and the power battery, give full play to the adjustable performance of the radiator, and is beneficial to reducing energy consumption.

[0056] In some embodiments, the adjusting component 331 includes: a sleeve 331a, a guiding structure 331b and a sliding valve block 331c.

[0057] As shown Figure 2 in the figure, the sleeve 331a is installed in the connecting water chamber 33, and the outer peripheral wall of the sleeve 331a is attached to the inner peripheral wall of the connecting water chamber 33, which is convenient for saving installation space and reducing the difficulty of design and layout. Among them, through holes are provided on the outer peripheral wall of the sleeve 331a, and the through holes are used to connect the sleeve 331a with the micro heat exchange channels.

[0058] The guiding structure 331b is installed in the sleeve 331a. The guiding structure 331b can be configured as a rail structure. The guiding structure 331b extends along the axial direction of the sleeve 331a. The sliding valve block 331c is sleeved outside the guiding structure 331b. The sliding valve block 331c is attached to the inner peripheral wall of the sleeve 331a. When the sliding valve block 331c moves axially along the guiding structure 331b, the sliding valve block 331c can separate the first-side heat exchange flow channel 31 and the second-side heat exchange flow channel 32, and the sliding valve block 331c can adjust the volumes of the chambers above and below it, so as to adjust the heat exchange areas of the first-side heat exchange flow channel 31 and the second-side heat exchange flow channel 32 to meet the different heat dissipation requirements of the two circuits.

[0059] It should be noted that the position of the sliding valve block 331c is controlled by the temperature signals of the motor heat exchange circuit 1 and the power battery heat exchange circuit 2. According to the temperature signals of the motor heat exchange circuit 1 and the power battery heat exchange circuit 2, the sliding valve block 331c moves along the axial direction of the guiding structure 331b, so as to realize the adjustment of the heat dissipation areas of the first-side heat exchange flow channel 31 and the second-side heat exchange flow channel 32, and thus reasonably distribute the heat dissipation efficiency of the adjustable radiator 3 in the two circuits.

[0060] Of course, the sleeve 331a may not be provided separately, that is, the adjusting assembly 331 includes the guiding structure 331b and the sliding valve block 331c. The guiding structure 331b can be directly installed in the connecting water chamber 33, and the sliding valve block 331c is sleeved on the guiding structure 331b, so that the sliding valve block 331c can be attached to the inner peripheral wall of the connecting water chamber 33, thereby separating the connecting water chamber into upper and lower parts. Thus, the sleeve 331a can be flexibly selected and set according to actual needs to ensure the stable sliding process of the sliding valve block 331c when the sleeve 331a is set, and to reduce the setting cost of the adjusting assembly 331 when the sleeve 331a is not set.

[0061] In some embodiments, the sliding valve blocks 331c corresponding to the adjusting components 331 in the two connecting water chambers 33 are arranged to be synchronously linked. That is to say, when the adjusting components 331 adjust the heat dissipation areas of the first-side heat exchange flow channels 31 and the second-side heat exchange flow channels 32, the two sliding valve blocks 331c move simultaneously along the axial direction of the guiding structure 331b, facilitating the adjustment of the heat dissipation areas of the first-side heat exchange flow channels 31 and the second-side heat exchange flow channels 32.

[0062] In the present invention, as Figure 2 shown, the first ends of the first-side heat exchange flow channels 31 and the first ends of the second-side heat exchange flow channels 32 are both located on the connecting water chamber 33 at the left end of the adjustable radiator 3, and the second ends of the first-side heat exchange flow channels 31 and the second ends of the second-side heat exchange flow channels 32 are both located on the connecting water chamber 33 at the right end of the adjustable radiator 3. Thus, the adjusting components 331 in the two connecting water chambers 33 can simultaneously adjust the heat dissipation areas of the two parts of the adjustable radiator 3, and the sliding valve blocks 331c in the two connecting water chambers 33 can move synchronously to improve the efficiency of heat dissipation ratio adjustment, reduce energy consumption, and improve the economy of the product.

[0063] It should be noted that, as Figure 3 and Figure 4 shown, Figure 3 the direction of the arrow in

[0064] is the windward direction of the vehicle 1000. That is to say, the external wind can blow towards the adjustable radiator 3 along the arrow direction, facilitating the heat dissipation of the motor heat exchange circuit 1 and the power battery heat exchange circuit 2, and making full use of the external wind received by the vehicle 1000 can further reduce energy consumption and improve the economy of the vehicle's thermal management system 100. At the same time, a fan 9 is also provided outside the adjustable radiator 3, and the air volume provided by the fan 9 can be used to further dissipate heat from the circuits in the vehicle's thermal management system 100. That is to say, cooling by using the windward wind of the vehicle 1000 or the air volume provided by the fan 9 can greatly reduce the energy loss required for the power battery to dissipate heat and require secondary heat exchange by air conditioning refrigeration during the heat dissipation process, facilitating the full use of the air volume of the oncoming wind and the heat dissipation capacity of the adjustable radiator 3, thereby reducing energy consumption. Figure 3As shown in the figure, the vehicle's thermal management system 100 further includes: a secondary water tank assembly 5. The secondary water tank assembly 5 can be used to store coolant. The secondary water tank assembly 5 is integrated with a first control valve 51. The first control valve 51 can control the coolant in the secondary water tank assembly 5 to dissipate heat from the motor heat exchange circuit 1 or the power battery heat exchange circuit 2. The first control valve 51 includes a first interface 511, a second interface 512, and a third interface 513. The first interface 511 and the second interface 512 are connected in series in the motor heat exchange circuit 1, facilitating the first control valve 51 to control the coolant in the secondary water tank assembly 5 to dissipate heat from the motor heat exchange circuit 1. The third interface 513 is connected to the power battery heat exchange circuit 2, facilitating the first control valve 51 to control the coolant in the secondary water tank assembly 5 to dissipate heat from the power battery heat exchange circuit 2. Any two of the first interface 511, the second interface 512, and the third interface 513 can be selectively connected. That is to say, the first control valve 51 can control different interfaces to be connected according to specific usage requirements, thereby controlling the vehicle's thermal management system 100 to execute different working modes to facilitate adaptation to different environmental conditions.

[0065] It should be noted that when the first control valve 51 controls the first interface 511 and the third interface 513 to be connected, the coolant does not flow through the adjustable radiator 3, enabling each circulation circuit to quickly warm up. When the first control valve 51 controls the second interface 512 and the third interface 513 to be connected, the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 are independently separated, and the two circuits are cooled separately to facilitate energy consumption reduction. Moreover, through the first control valve 51, the vehicle's thermal management system 100 can have different working modes, thereby reducing energy consumption.

[0066] As Figure 3 shown in the figure, the secondary water tank assembly 5 is further integrated with a three-way joint 52. The three-way joint 52 includes a first opening 521, a second opening 522, and a third opening 523. The first opening 521 is connected to the third interface 513, that is, the three-way joint 52 is connected to the motor heat exchange circuit 1 through the third interface 513. The second opening 522 and the third opening 523 are connected in series in the power battery heat exchange circuit 2. The first opening 521, the second opening 522, and the third opening 523 are interconnected, facilitating the connection between the motor heat exchange circuit 1 and the power battery heat exchange circuit 2, thereby reducing energy consumption.

[0067] Among them, the secondary water tank assembly 5 can replenish the heat exchange medium into the motor heat exchange circuit 1 through the first control valve 51, and can replenish the heat exchange medium into the power battery heat exchange circuit 2 through the three-way joint 52, thereby ensuring that there is sufficient heat exchange medium in the thermal management system for heat transfer.

[0068] As Figure 1 shown in the figure, in some embodiments, the vehicle's thermal management system 100 further includes: an electric heating circuit 4.

[0069] The electric heating circuit 4 is used to heat the motor heat exchange circuit 1 and / or the power battery heat exchange circuit 2. That is to say, according to the specific usage environment, the electric heating circuit 4 can select different working modes. Among them, the electric heating circuit 4 can heat the motor heat exchange circuit 1 alone, or the electric heating circuit 4 can heat the power battery heat exchange circuit 2 alone. Or, the electric heating circuit 4 can heat the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 at the same time. Through one electric heating circuit 4, multiple working modes can be realized, which is beneficial to reducing the number of other components, reducing the difficulty of design and layout, and reducing the installation cost. It should be noted that the electric heating circuit 4 can be constructed to generate heat by a PTC electric heater, so as to facilitate heating the motor heat exchange circuit 1 and / or the power battery heat exchange circuit 2.

[0070] As Figures 6 - 8 shown, in some embodiments, the vehicle's thermal management system 100 further includes: a four-way valve 6. The four-way valve 6 includes a first inlet 61, a second inlet 62, a first outlet 63, and a second outlet 64. The first inlet 61 and the second outlet 64 are both connected to the power battery heat exchange circuit 2, and the first outlet 63 and the second inlet 62 are both connected to the electric heating circuit 4, so as to facilitate the electric heating circuit 4 to heat the power battery circuit.

[0071] In some embodiments, as Figures 9 - 12 shown, the vehicle's thermal management system 100 further includes: a power battery heat exchanger 7 and an air-conditioning refrigeration circuit 8. The first-side cooling flow channel 71 of the power battery heat exchanger 7 is connected to the power battery heat exchange circuit 2, and the second-side cooling flow channel 72 of the power battery heat exchanger 7 is connected to the air-conditioning refrigeration circuit 8, and the first-side cooling flow channel 71 and the second-side cooling flow channel 72 are attached and connected. That is to say, the heat of the power battery heat exchange circuit 2 is absorbed through the first-side cooling flow channel 71, and then the heat is transferred to the second-side cooling flow channel 72 through the first-side cooling flow channel 71. At this time, the heat in the second-side cooling flow channel 72 is taken away by using the cooling medium in the air-conditioning refrigeration circuit 8, so that the power battery heat exchanger 7 dissipates heat from the power battery heat exchange circuit 2. Through such a setting method, it is easy to reduce the difficulty of design and layout, reduce the installation cost, and is beneficial to reducing energy consumption.

[0072] It should be noted that when the ambient temperature is relatively low, as Figure 7 shown (the first state mode), the four-way valve 6 controls the first inlet 61 to be connected to the first outlet 63 and the second inlet 62 to be connected to the second outlet 64. At this time, the motor heat exchange circuit 1 and the electric heating circuit 4 jointly heat the power battery heat exchange circuit 2, as Figure 9As shown, the first control valve 51 closes the second interface 512, controls the first interface 511 and the third interface 513 to be connected, so as to facilitate the series connection of the power battery heat exchange circuit 2, the electric heating circuit 4 and the motor heat exchange circuit 1. At this time, the adjustable radiator 3 adjusts the sliding valve block 331c to be at the lowest position of the guide rail, the first side heat exchange channel 31 and the second side heat exchange channel 32 are connected, the coolant does not flow through the adjustable radiator 3, and the motor heat exchange circuit 1 and the electric heating circuit 4 are heated to a suitable temperature to obtain the best efficiency, which is beneficial for the power battery heat exchange circuit 2 to be heated together by the electric heating circuit 4 and the motor heat exchange circuit 1 at a low temperature, so that the key components such as the motor, electronic control, charging and distribution and power battery in the vehicle's thermal management system 100 can be quickly heated to reach a suitable working temperature.

[0073] Among them, Figure 8 As shown in the second state mode, when the first inlet 61 is connected to the second outlet 64 and the second inlet 62 is connected to the first outlet 63, the first control valve 51 controls the first opening 521 to be connected to the third opening 523, so that the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 are connected in series. At this time, the motor heat exchange circuit 1 heats the power battery heat exchange circuit 2 alone, and the heat generated by the motor can be directly transferred to the power battery. Figure 10 As shown, when the heat of the motor heat exchange circuit 1 is sufficient during the operation of the vehicle 1000 (determined by the body water temperature sensor signal), the adjustable radiator 3 adjusts the sliding valve block 331c to be at the lowest position of the guide rail, the first side heat exchange channel 31 and the second side heat exchange channel 32 are connected, and the coolant does not flow through the adjustable radiator 3. At this time, the electric heating circuit 4 works alone according to the needs of the occupants, and the power battery heat exchange circuit 2 is heated alone by the motor heat exchange circuit 1 to recover the waste heat of the motor heat exchange circuit 1. The recovered heat is estimated to be 2kW-5kW, which is convenient for making full use of the waste heat of the motor heat exchange circuit 1. There is no need to actively heat the power battery through a separate heating circuit, thereby reducing the active work energy required for heating the power battery, which is beneficial to reducing energy consumption.

[0074] When the ambient temperature is normal, the ambient temperature is about 10℃~30℃. Figure 11As shown, the first control valve 51 closes the third interface 513 and controls the communication between the first interface 511 and the second interface 512. The four-way valve 6 controls the communication between the first inlet 61 and the first outlet 63 and the communication between the second inlet 62 and the second outlet 64. At this time, during the operation of the vehicle 1000, the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 dissipate heat through the adjustable radiator 3. The adjustment sliding valve block 331c in the adjustable radiator 3 adjusts its position on the guiding structure 331b according to the performance requirements of the motor heat exchange circuit 1 and the power battery heat exchange circuit 2, thereby changing the heat dissipation area of the second-side heat exchange flow channel 32, facilitating the heat dissipation of the power battery heat exchange circuit 2. At the same time, by using the wind volume provided by the vehicle 1000 facing the wind or the fan 9 for cooling, the energy loss required for the power battery heat exchange circuit 2 to perform secondary heat exchange with air conditioning refrigeration during this process can be greatly reduced, and the adjustment performance of the adjustable radiator 3 and the heat dissipation capacity of the oncoming wind can be fully utilized.

[0075] When the ambient temperature is relatively high, such as Figure 12 shown, usually when the ambient temperature exceeds 30°C, the four-way valve 6 controls the conduction between the second inlet 62 and the second outlet 64. After the battery temperature rises to 33°C, the power battery heat exchanger 7 and the air conditioning refrigeration circuit 8 are turned on to facilitate the heat dissipation of the power battery heat exchange circuit 2. At the same time, the heat in the motor heat exchange circuit 1 is relatively high and the heat dissipation demand is large. The radiator adjustment sliding valve block 331c slides to the lowest position of the adjustable radiator 3, and the adjustable radiator 3 dissipates heat for the motor heat exchange circuit 1 alone. The air conditioning refrigeration circuit 8 is turned on, and the power battery heat exchange circuit 2 takes away the internal heat through the power battery heat exchanger 7, which is beneficial to controlling the power battery at the most suitable temperature condition under high-temperature environments, improving the safety of the power battery. Through this mode, it can be realized that when the ambient temperature is relatively high, both the motor heat exchange circuit 1 and the power battery heat exchange circuit 2 can achieve independent heat dissipation, improving the heat dissipation efficiency.
