[0066] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0067] The following is for reference. Figures 1-12 A thermal management system 1000 according to an embodiment of the present invention is described. The thermal management system 1000 can be applied to a vehicle, but this application is not limited thereto. The thermal management system 1000 can be applied to other equipment that requires the thermal management system 1000. This application uses the application of the thermal management system 1000 to a vehicle as an example for description.

[0068] like Figure 1 As shown, according to an embodiment of the present invention, the thermal management system 1000 includes a first heat exchanger 6, a compressor 1, a first air conditioning heat exchanger 17, a first drive pump 16, and a heat exchange flow path.

[0069] The first heat exchanger 6 has a first heat exchange channel and a second heat exchange channel that exchange heat with each other. The second heat exchanger 4 has a third heat exchange channel and a fourth heat exchange channel that exchange heat with each other. The compressor 1 has a compressor inlet 1a and a compressor outlet 1b. The compressor inlet 1a is selectively connected to either the first heat exchange interface 6a or the second heat exchange interface 6b of the first heat exchange channel. The compressor outlet 1b is selectively connected to either the first heat exchange interface 6a or the third heat exchange interface 4a of the third heat exchange channel. The first air conditioning heat exchanger 17 has a first interface 17a and a second interface 17b that are connected. The first interface 17a is connected to the pump outlet of the first drive pump 16, and the second interface 17b is connected to the fifth heat exchange interface 6c of the second heat exchange channel.

[0070] The heat exchange flow path includes a second air conditioning heat exchanger 20, a radiator 13, and a second drive pump 14. The second air conditioning heat exchanger 20 has a third port 20a and a fourth port 20b that are connected. The third port 20a is selectively connected to the sixth heat exchange port 4b of the fourth heat exchange flow path or the pump outlet of the first drive pump 16. The pump inlet of the first drive pump 16 is connected to the fourth heat exchange port 6d. The fourth port 20b is selectively connected to the fifth heat exchange port 6c or the seventh heat exchange port 4d of the fourth heat exchange flow path. The radiator 13 has a radiator inlet 13a and a radiator outlet 13b. The radiator inlet 13a is selectively connected to the fourth port 20b or the sixth heat exchange port 4b, and the radiator outlet 13b is connected to the seventh heat exchange port 4d. The second drive pump 14 is used to drive the heat exchange medium to flow within the heat exchange flow path.

[0071] Specifically, such as Figure 1 As shown, both the first heat exchanger 6 and the second heat exchanger 4 can be constructed as refrigerant water heat exchangers. The refrigerant water heat exchanger has two mutually heat-exchanging but non-connected flow channels, and the heat exchange medium flowing through the two flow channels can be different. The heat exchange medium can be refrigerant and coolant, so that the heat exchange medium (refrigerant) and the heat exchange medium (coolant) can exchange heat with each other as the two heat exchange media flow through the two flow channels respectively. Furthermore, both the first heat exchanger 6 and the second heat exchanger 4 can be located outside the passenger compartment of the vehicle, which helps to prevent the heat exchange medium (refrigerant) from entering the passenger compartment.

[0072] Furthermore, such as Figure 1 As shown, compressor 1 is used to compress the heat exchange medium (refrigerant). The heat exchange medium (refrigerant) can flow into compressor 1 from compressor inlet 1a for compression. After being compressed by compressor 1, the heat exchange medium (refrigerant) is discharged from compressor outlet 1b. Compressor 1 can be located outside the passenger compartment of the vehicle, which helps to prevent the heat exchange medium (refrigerant) from entering the passenger compartment. Figure 4 As shown, when the compressor inlet 1a is connected to the first heat exchange interface 6a, the compressor 1 is connected to the first heat exchange channel of the first heat exchanger 6, thereby enabling the heat exchange medium (refrigerant) to flow into the compressor 1 from the first heat exchange channel. Figure 7 As shown, when the compressor inlet 1a is connected to the second heat exchange interface 6b, the compressor 1 is connected to the first heat exchange channel of the first heat exchanger 6, thereby realizing the effect of the heat exchange medium (refrigerant) flowing into the compressor 1 from the first heat exchange channel.

[0073] Furthermore, such as Figure 7 As shown, the compressor outlet 1b is connected to the first heat exchange interface 6a, thereby enabling the compressor 1 to transport the heat exchange medium (refrigerant) to the first heat exchange channel, so that the heat exchange medium (refrigerant) can exchange heat when flowing through the first heat exchange channel. Figure 4As shown, the compressor outlet 1b can also be connected to the third heat exchange interface 4a, thereby enabling the compressor 1 to transport the heat exchange medium (refrigerant) to the third heat exchange channel so that the heat exchange medium (refrigerant) can exchange heat when flowing through the third heat exchange channel.

[0074] Therefore, the heat exchange medium flowing through the first heat exchange channel of the first heat exchanger 6 is a refrigerant, the heat exchange medium flowing through the second heat exchange channel that cooperates with the first heat exchange channel is a coolant, the heat exchange medium flowing through the third heat exchange channel of the second heat exchanger 4 is a refrigerant, and the heat exchange medium flowing through the fourth heat exchange channel that cooperates with the third heat exchange channel is a coolant.

[0075] The first air conditioning heat exchanger 17 is used for heat exchange medium flowing through the first air conditioning heat exchanger 17 to exchange heat with air. When the heat exchange medium flows through the first air conditioning heat exchanger 17, the heat exchange medium can transfer heat to the air, achieving the effect of heat release by the heat exchange medium, thereby increasing the air temperature. Alternatively, the heat exchange medium can absorb heat from the air, achieving the effect of heat absorption by the heat exchange medium, thereby decreasing the air temperature.

[0076] The first drive pump 16 can be configured as a water pump. The first drive pump 16 is used to start the flow of heat exchange medium. The heat exchange medium flows into the first drive pump 16 from the pump inlet and flows out of the first drive pump 16 from the pump outlet under the action of the first drive pump 16.

[0077] Furthermore, such as Figure 4 As shown, the pump inlet of the first drive pump 16 is connected to the fourth heat exchange interface 6d, achieving the effect of connecting the first drive pump 16 to the second heat exchange channel, so that the heat exchange medium (coolant) can flow from the second heat exchange channel into the first drive pump 16. Furthermore, the pump outlet of the first drive pump 16 is connected to the first interface 17a, achieving the effect of connecting the first air conditioning heat exchanger 17 to the first drive pump 16, so that the first drive pump 16 can deliver the heat exchange medium (coolant) to the first air conditioning heat exchanger 17. Moreover, since the second interface 17b is connected to the fifth heat exchange interface 6c, the heat exchange medium (coolant) can be returned to the second heat exchange channel via the first drive pump 16.

[0078] The second air conditioning heat exchanger 20 is used for heat exchange between the heat exchange medium flowing through it and the air. When the heat exchange medium flows through the second air conditioning heat exchanger 20, it can transfer heat to the air, achieving a heat release effect and thus raising the air temperature. Alternatively, the heat exchange medium can absorb heat from the air, achieving a heat absorption effect and thus lowering the air temperature.

[0079] The radiator 13 is used for heat exchange between the heat exchange medium flowing through it and the air. When the heat exchange medium flows through the radiator 13, it can transfer heat to the air, achieving a heat release effect and thus raising the air temperature. Alternatively, the heat exchange medium can absorb heat from the air, achieving a heat absorption effect and thus lowering the air temperature.

[0080] The second drive pump 14 can be configured as a water pump. The second drive pump 14 is used to drive the flow of the heat exchange medium. The second drive pump 14 has a pump inlet and an outlet. The heat exchange medium flows into the second drive pump 14 from the pump inlet and flows out of the second drive pump 14 from the pump outlet under the action of the second drive pump 14. Furthermore, the second drive pump 14 is located in the heat exchange flow path so that the heat exchange flow path drives the flow of the heat exchange medium (coolant) flowing along the heat exchange flow path.

[0081] Furthermore, such as Figure 5 As shown, when the sixth heat exchange port 4b is connected to the third port 20a, the second heat exchanger 4 and the second air conditioning heat exchanger 20 are connected, so that the heat exchange medium (coolant) in the fourth heat exchange channel can flow into the second air conditioning heat exchanger 20, thereby achieving the effect of heat exchange of the heat exchange medium (coolant). Figure 4 As shown, when the pump outlet of the first drive pump 16 is connected to the third interface 20a, the first drive pump 16 is connected to the second air conditioning heat exchanger 20. Furthermore, since the pump inlet of the first drive pump 16 is connected to the fourth heat exchange interface 6d, the second air conditioning heat exchanger 20 is connected to the second heat exchange channel. This allows the heat exchange medium (coolant) in the second heat exchange channel to flow into the second air conditioning heat exchanger 20 when the pump outlet of the first drive pump 16 is connected to the third interface 20a.

[0082] Furthermore, such as Figure 4 As shown in the figure, when the fourth interface 20b is connected to the fifth heat exchange interface 6c, the second air conditioning heat exchanger 20 is connected to the second heat exchange channel, thereby enabling the heat exchange medium (coolant) to flow from the second air conditioning heat exchanger 20 into the second heat exchange channel. As shown in the figure, when the fourth interface 20b is connected to the seventh heat exchange interface 4d, the second air conditioning heat exchanger 20 is connected to the fourth heat exchange channel, thereby enabling the heat exchange medium (coolant) to flow from the second air conditioning heat exchanger 20 into the fourth heat exchange channel.

[0083] Furthermore, such as Figure 5As shown, when the radiator inlet 13a is connected to the fourth interface 20b, the radiator 13 is connected to the second heat exchange channel, thereby enabling the heat exchange medium (coolant) to flow into the radiator 13 from the second heat exchange channel, so that the heat exchange medium (coolant) exchanges heat with the air during the flow through the radiator 13. As shown, when the radiator outlet 13b is connected to the seventh interface, the radiator 13 is connected to the fourth heat exchange channel, thereby enabling the heat exchange medium (coolant) to flow into the fourth heat exchange channel from the radiator 13.

[0084] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the compressor outlet 1b is connected to the third heat exchange interface 4a of the third heat exchange channel, the third heat exchange channel is connected to the second heat exchange interface 6b of the first heat exchange channel, and the first heat exchange interface 6a of the first heat exchange channel is connected to the compressor inlet 1a. This achieves the effect of the compressor 1, the third heat exchange channel, and the first heat exchange channel sequentially connecting to form a closed loop first flow path [passenger compartment cooling mode, passenger compartment and battery cooling mode, dehumidification mode, first mode of cooling and heat recovery, and second mode of cooling and heat recovery], so that the heat exchange medium (refrigerant) flows along the first flow path, and heat exchange occurs during the process of the heat exchange medium (refrigerant) flowing through the third heat exchange channel and the first heat exchange channel.

[0085] Furthermore, such as Figure 4 and Figure 5 As shown, the fourth heat exchange interface 6d of the second heat exchange channel is connected to the pump inlet of the first drive pump 16, the pump outlet of the first drive pump 16 is connected to the first interface 17a of the first air conditioning heat exchanger 17, and the second interface 17b of the first air conditioning heat exchanger 17 is connected to the fifth heat exchange interface 6c of the second heat exchange channel. This achieves the effect of the second heat exchange channel, the first drive pump 16, and the first air conditioning heat exchanger 17 being sequentially connected to form a closed loop second flow path, so that the heat exchange medium (coolant) flows along the second flow path and heat exchange occurs during the process of the heat exchange medium (coolant) flowing through the second heat exchange channel and the first air conditioning heat exchanger 17.

[0086] Furthermore, such as Figure 4 As shown, the pump outlet of the first drive pump 16 is also connected to the third interface 20a of the second air conditioning heat exchanger 20, and the fourth interface 20b of the second air conditioning heat exchanger 20 is connected to the fifth heat exchange interface 6c of the second heat exchange channel. This achieves the effect of the second heat exchange channel, the first drive pump 16, and the second air conditioning heat exchanger 20 being connected in sequence to form a closed loop third flow path, so that the heat exchange medium (coolant) flows along the third flow path and heat exchange occurs during the process of the heat exchange medium (coolant) flowing through the second heat exchange channel and the second air conditioning heat exchanger 20.

[0087] In some embodiments of the present invention, such as Figure 7As shown, the compressor outlet 1b is connected to the first heat exchange interface 6a of the first heat exchange channel, the second heat exchange interface 6b of the first heat exchange channel is connected to the third heat exchange channel, and the third heat exchange interface 4a of the third heat exchange channel is connected to the compressor outlet 1b inlet. This achieves the effect of the compressor 1, the first heat exchange channel, and the third heat exchange channel being connected in sequence to form a closed loop fourth flow path, so that the heat exchange medium (refrigerant) flows along the fourth flow path and the heat exchange medium (refrigerant) undergoes heat exchange as it flows through the second heat exchange channel and the first air conditioning heat exchanger 17.

[0088] In some embodiments of the present invention, such as Figure 6 As shown, the sixth heat exchange port 4b of the fourth heat exchange channel is connected to the radiator inlet 13a, and the radiator outlet 13b is connected to the seventh heat exchange port 4d of the fourth heat exchange channel, so that the fourth heat exchange channel and the radiator 13 are connected to form a closed loop fifth flow path in the heat exchange flow path, so that the heat exchange medium (coolant) flows along the fifth flow path and heat exchange occurs during the process of the heat exchange medium (coolant) flowing through the fourth heat exchange channel and the radiator 13.

[0089] In some embodiments of the present invention, such as Figure 5 As shown, the sixth heat exchange port 4b of the fourth heat exchange channel is connected to the third port 20a of the second air conditioning heat exchanger 20, the fourth port 20b of the second air conditioning heat exchanger 20 is connected to the radiator inlet 13a, and the radiator outlet 13b is connected to the seventh heat exchange port 4d of the fourth heat exchange channel. This allows the fourth heat exchange channel, the second air conditioning heat exchanger 20, and the radiator 13 to be sequentially connected to form a closed loop sixth flow path, so that the heat exchange medium (coolant) flows along the sixth flow path and heat exchange occurs as the heat exchange medium (coolant) flows through the fourth heat exchange channel, the second air conditioning heat exchanger 20, and the radiator 13.

[0090] In some embodiments of the present invention, such as Figure 4 As shown, after the heat exchange medium (refrigerant) is compressed by compressor 1, it is in a high-temperature and high-pressure state, so that the high-temperature and high-pressure heat exchange medium (refrigerant) flows out of compressor 1 from compressor outlet 1b. Further, as... Figure 4 As shown, during the flow of the heat exchange medium (refrigerant) along the first flow path, when the heat exchange medium (refrigerant) flows through the third heat exchange channel of the second heat exchanger 4, the heat exchange medium (refrigerant) in the third heat exchange channel exchanges heat with the heat exchange medium (coolant) in the fourth heat exchange channel of the second heat exchanger 4, so that the heat exchange medium (refrigerant) in the third heat exchange channel transfers heat to the heat exchange medium (coolant) in the fourth heat exchange channel. The heat exchange medium (refrigerant) in the third heat exchange channel is in an exothermic state, and the heat exchange medium (coolant) in the fourth heat exchange channel is in an endothermic state, thereby reducing the temperature of the heat exchange medium (refrigerant) in the third heat exchange channel and increasing the temperature of the heat exchange medium (coolant) in the fourth heat exchange channel.

[0091] The heat exchange medium (refrigerant) that has been cooled by heat exchange in the third heat exchange channel of the second heat exchanger 4 flows into the first heat exchange channel of the first heat exchanger 6 along the first flow path. The heat exchange medium (refrigerant) in the first heat exchange channel exchanges heat with the heat exchange medium (coolant) in the second heat exchange channel of the first heat exchanger 6, so that the heat exchange medium (refrigerant) in the first heat exchange channel absorbs the heat of the heat exchange medium (coolant) in the second heat exchange channel. The heat exchange medium (refrigerant) in the first heat exchange channel is in an endothermic state, and the heat exchange medium (refrigerant) in the second heat exchange channel is in an exothermic state, thereby raising the temperature of the heat exchange medium (refrigerant) in the first heat exchange channel and lowering the temperature of the heat exchange medium (coolant) in the second heat exchange channel.

[0092] Therefore, during the flow of the heat exchange medium (refrigerant) along the first flow path, the heat exchange medium (refrigerant) releases heat in the third heat exchange channel and absorbs heat in the first heat exchange channel.

[0093] In some embodiments of the present invention, such as Figure 7 As shown, during the flow of the heat exchange medium (refrigerant) along the fourth flow path, when the heat exchange medium (refrigerant) flows through the first heat exchange channel of the first heat exchanger 6, the heat exchange medium (refrigerant) in the first heat exchange channel exchanges heat with the heat exchange medium (coolant) in the second heat exchange channel of the first heat exchanger 6, so that the heat exchange medium (refrigerant) in the first heat exchange channel transfers heat to the heat exchange medium (coolant) in the second heat exchange channel. The heat exchange medium (refrigerant) in the first heat exchange channel is in an exothermic state, and the heat exchange medium (coolant) in the second heat exchange channel is in an endothermic state, thereby reducing the temperature of the heat exchange medium (refrigerant) in the first heat exchange channel and increasing the temperature of the heat exchange medium (coolant) in the second heat exchange channel.

[0094] When the heat exchange medium (refrigerant) that has been cooled by heat exchange in the first heat exchange channel flows into the third heat exchange channel of the second heat exchanger 4 along the fourth flow path, the heat exchange medium (refrigerant) in the third heat exchange channel exchanges heat with the heat exchange medium (coolant) in the fourth heat exchange channel of the second heat exchanger 4. This allows the heat exchange medium (refrigerant) in the third heat exchange channel to absorb heat from the heat exchange medium (coolant) in the fourth heat exchange channel. The heat exchange medium (refrigerant) in the third heat exchange channel is in an endothermic state, while the heat exchange medium (coolant) in the fourth heat exchange channel is in an exothermic state. This raises the temperature of the heat exchange medium (refrigerant) in the third heat exchange channel and lowers the temperature of the heat exchange medium (coolant) in the fourth heat exchange channel.

[0095] Therefore, during the flow of the heat exchange medium (refrigerant) along the fourth flow path, the heat exchange medium (refrigerant) releases heat in the first heat exchange channel and absorbs heat in the third heat exchange channel.

[0096] In some embodiments of the present invention, such as Figure 4As shown, when the heat exchange medium (refrigerant) flows along the first flow path and the heat exchange medium (coolant) flows along the second flow path, since the heat exchange medium (refrigerant) in the second heat exchange channel of the first heat exchanger 6 is in an exothermic state, the temperature of the heat exchange medium (coolant) in the second heat exchange channel is relatively low. During the flow of the heat exchange medium (coolant) along the second flow path, the heat exchange medium (coolant) in the second heat exchange channel is transported to the first air conditioning heat exchanger 17 by the first drive pump 16. When the heat exchange medium (coolant) flows through the first air conditioning heat exchanger 17, the heat exchange medium (coolant) in the first air conditioning heat exchanger 17 can exchange heat with the air. The heat exchange medium (coolant) in the first air conditioning heat exchanger 17 can be in an absorbing state, and the heat exchange medium (coolant) in the first air conditioning heat exchanger 17 can absorb heat from the air, thereby increasing the temperature of the heat exchange medium (coolant) in the first air conditioning heat exchanger 17 and decreasing the temperature of the air exchanging heat with the first air conditioning heat exchanger 17. Furthermore, the heat exchange medium (coolant) that has been heated by the first air conditioning heat exchanger 17 flows into the second heat exchange channel along the second flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the fourth flow path.

[0097] In some embodiments of the present invention, such as Figure 4 As shown, when the heat exchange medium (refrigerant) flows along the first flow path and the heat exchange medium (coolant) flows along the third flow path, since the heat exchange medium (refrigerant) in the second heat exchange channel of the first heat exchanger 6 is in an exothermic state, the temperature of the heat exchange medium (coolant) in the second heat exchange channel is relatively low. During the flow of the heat exchange medium (coolant) along the third flow path, the heat exchange medium (coolant) in the second heat exchange channel is transported to the second air conditioning heat exchanger 20 by the first drive pump 16. When the heat exchange medium (coolant) flows through the second air conditioning heat exchanger 20, the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 can exchange heat with the air. The heat exchange medium (coolant) in the second air conditioning heat exchanger 20 can be in an absorbing state, absorbing heat from the air, thereby increasing the temperature of the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 and decreasing the temperature of the air exchanging heat with the second air conditioning heat exchanger 20. Furthermore, the heat exchange medium (coolant) that has been heated by the second air conditioning heat exchanger 20 flows into the second heat exchange channel along the third flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the third flow path.

[0098] In some embodiments of the present invention, such as Figure 4As shown, the heat exchange medium (refrigerant) flows along the first flow path, and the heat exchange medium (coolant) flows along the fifth flow path. Since the heat exchange medium (coolant) in the fourth heat exchange channel of the second heat exchanger 4 is in an endothermic state, its temperature is relatively high. During the flow of the heat exchange medium (coolant) along the fifth flow path, under the driving action of the second drive pump 14, the heat exchange medium (coolant) in the fourth heat exchange channel is transported to the radiator 13. When the heat exchange medium (coolant) flows through the radiator 13, it can exchange heat with the air. When the temperature of the heat exchange medium (coolant) in the radiator 13 is higher than the air temperature, it transfers heat to the air, and is in an exothermic state. When the temperature of the heat exchange medium (coolant) in the radiator 13 is lower than the air temperature, it absorbs heat from the air, and is in an endothermic state.

[0099] The heat exchange medium (coolant) inside the radiator 13 transfers heat to the air, thereby reducing the temperature of the heat exchange medium (coolant) inside the radiator 13. Furthermore, the heat exchange medium (coolant) cooled by heat exchange in the radiator 13 flows into the fourth heat exchange channel along the fifth flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the fifth flow path.

[0100] In some embodiments of the present invention, such as Figure 6 As shown, the heat exchange medium (refrigerant) flows along the first flow path, and the heat exchange medium (coolant) flows along the sixth flow path. Since the heat exchange medium (coolant) in the fourth heat exchange channel of the second heat exchanger 4 is in an endothermic state, its temperature is relatively high. During the flow of the heat exchange medium (coolant) along the sixth flow path, under the driving action of the second drive pump 14, the heat exchange medium (coolant) in the fourth heat exchange channel is transported to the second air conditioning heat exchanger 20. When the heat exchange medium (coolant) flows through the second air conditioning heat exchanger 20, it can exchange heat with the air. Alternatively, it can be in an exothermic state, transferring heat to the air, thereby reducing the temperature of the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 and increasing the temperature of the air exchanging heat with the second air conditioning heat exchanger 20.

[0101] Furthermore, the heat exchange medium (coolant) that has been cooled by heat exchange in radiator 13 flows into radiator 13 along the sixth flow path. When the heat exchange medium (coolant) flows through radiator 13, it exchanges heat with the air. When the temperature of the heat exchange medium (coolant) in radiator 13 is higher than the air temperature, the heat exchange medium (coolant) in radiator 13 transfers heat to the air, and the heat exchange medium (coolant) in radiator 13 is in an exothermic state. When the temperature of the heat exchange medium (coolant) in radiator 13 is lower than the air temperature, the heat exchange medium (coolant) in radiator 13 absorbs heat from the air, and the heat exchange medium (coolant) in radiator 13 is in an absorbing state.

[0102] Furthermore, the heat exchange medium (coolant) cooled by the radiator 13 flows into the fourth heat exchange channel along the sixth flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the sixth flow path.

[0103] In some embodiments of the present invention, such as Figure 7 As shown, when the heat exchange medium (refrigerant) flows along the fourth flow path and the heat exchange medium (coolant) flows along the second flow path, the heat exchange medium (coolant) in the second heat exchange channel of the first heat exchanger 6 is in an endothermic state, and its temperature is relatively high. During the flow of the heat exchange medium (coolant) along the second flow path, it is transported to the first air conditioning heat exchanger 17 by the first drive pump 16. When the heat exchange medium (coolant) flows through the first air conditioning heat exchanger 17, it can exchange heat with the air. Alternatively, it can be in an exothermic state, transferring heat to the air, thereby lowering the temperature of the heat exchange medium (coolant) in the first air conditioning heat exchanger 17 and raising the temperature of the air exchanging heat with the first air conditioning heat exchanger 17. Furthermore, the heat exchange medium (coolant) that has been cooled by the first air conditioning heat exchanger 17 flows into the second heat exchange channel along the second flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the second flow path.

[0104] In some embodiments of the present invention, such as Figure 7As shown, when the heat exchange medium (refrigerant) flows along the fourth flow path and the heat exchange medium (coolant) flows along the third flow path, the heat exchange medium (coolant) in the second heat exchange channel of the first heat exchanger 6 is in an endothermic state, and its temperature is relatively high. During the flow of the heat exchange medium (coolant) along the second flow path, it is transported to the second air conditioning heat exchanger 20 by the first drive pump 16. When the heat exchange medium (coolant) flows through the second air conditioning heat exchanger 20, it can exchange heat with the air. Alternatively, it can be in an exothermic state, allowing it to transfer heat to the air, thereby reducing the temperature of the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 and increasing the temperature of the air exchanging heat with the second air conditioning heat exchanger 20. Furthermore, the heat exchange medium (coolant) that has been cooled by the second air conditioning heat exchanger 20 flows into the second heat exchange channel along the third flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the third flow path.

[0105] In some embodiments of the present invention, such as Figure 7 As shown, the heat exchange medium (refrigerant) flows along the fourth flow path, and the heat exchange medium (coolant) flows along the fifth flow path. Since the heat exchange medium (coolant) in the fourth heat exchange channel of the second heat exchanger 4 is in an exothermic state, the temperature of the heat exchange medium (coolant) in the fourth heat exchange channel is relatively low. During the flow of the heat exchange medium (coolant) along the fifth flow path, the lower-temperature heat exchange medium (coolant) is delivered to the radiator 13 by the second drive pump 14. When the heat exchange medium (coolant) flows through the radiator 13, the heat exchange medium (coolant) in the radiator 13 can exchange heat with the air. When the temperature of the heat exchange medium (coolant) in the radiator 13 is higher than the air temperature, the heat exchange medium (coolant) in the radiator 13 transfers heat to the air, and the heat exchange medium (coolant) in the radiator 13 is in an exothermic state. When the temperature of the heat exchange medium (coolant) in the radiator 13 is lower than the air temperature, the heat exchange medium (coolant) in the radiator 13 absorbs heat from the air, and the heat exchange medium (coolant) in the radiator 13 is in an endothermic state.

[0106] Furthermore, the heat exchange medium (coolant) cooled by the radiator 13 flows into the fourth heat exchange channel along the fifth flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the fifth flow path.

[0107] In some embodiments of the present invention, such as Figure 8As shown, when the heat exchange medium (refrigerant) flows along the fourth flow path and the heat exchange medium (coolant) flows along the sixth flow path, the heat exchange medium (coolant) in the fourth heat exchange channel of the second heat exchanger 4 is in an exothermic state, and its temperature is relatively low. During the flow of the heat exchange medium (coolant) along the sixth flow path, it is transported to the second air conditioning heat exchanger 20 by the second drive pump 14. When the heat exchange medium (coolant) flows through the second air conditioning heat exchanger 20, it exchanges heat with the air. Since the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 is in an exothermic state, it transfers heat to the air, thereby lowering the temperature of the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 and raising the temperature of the air exchanging heat with the second air conditioning heat exchanger 20.

[0108] Furthermore, the heat exchange medium (coolant) that has been cooled by heat exchange in radiator 13 flows into radiator 13 along the sixth flow path. When the heat exchange medium (coolant) flows through radiator 13, it exchanges heat with the air. The heat exchange medium (coolant) in radiator 13 is in an exothermic state, transferring heat to the air. When the temperature of the heat exchange medium (coolant) in radiator 13 is higher than the air temperature, it transfers heat to the air, remaining in an exothermic state. When the temperature of the heat exchange medium (coolant) in radiator 13 is lower than the air temperature, it absorbs heat from the air, becoming an endothermic state.

[0109] Furthermore, the heat exchange medium (coolant) cooled by the radiator 13 flows into the fourth heat exchange channel along the sixth flow path, thereby achieving the effect of circulating the heat exchange medium (coolant) along the sixth flow path.

[0110] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the thermal management system 1000 may further include a temperature control device 500, which includes a duct body 50, a first duct wall 51, and a second duct wall 52. The duct body 50 defines a ventilation space 53. The first duct wall 51 and the second duct wall 52 are disposed within the ventilation space 53, such that the first duct wall 51 defines a first duct 501 and a second duct 502 within the ventilation space 53, and the second duct wall 52 defines a third duct 503 and a fourth duct 504 within the ventilation space 53.

[0111] Furthermore, such as Figure 2 and Figure 3As shown, the temperature control device 500 may have a rotatable rotary damper 54, one end of which is rotatably connected to the first air duct wall 51, and the other end of which is selectively connected to the second air duct wall 52 or the air duct body 50. Figure 2 As shown, when the other end of the rotary damper 54 is connected to the second duct wall 52, that is, when the rotary damper 54 is opened to point A, as shown... Figure 3 As shown, when the other end of the rotating damper 54 is connected to the air duct body 50, that is, when the rotating damper 54 is opened to point A, it should be noted that in the following description, when the rotating damper 54 is opened to point A, it is the temperature control air duct A mode, and when the rotating damper 54 is opened to point B, it is the temperature control air duct B mode.

[0112] Furthermore, such as Figure 2 As shown, in temperature-controlled air duct mode A, the first air duct 501 and the third air duct 503 are connected, the second air duct 502 and the fourth air duct 504 are connected, the first air duct 501 and the third air duct 503 are connected to form the first flow channel 505, the second air duct 502 and the fourth air duct 504 are connected to form the second flow channel 506, and the first flow channel 505 and the second flow channel 506 are not connected. Figure 3 As shown, in temperature-controlled air duct mode B, the rotating damper 54 blocks the second air duct 502, and the first air duct 501, the third air duct 503 and the fourth air duct 504 are interconnected.

[0113] Furthermore, such as Figure 2 and Figure 3 As shown, the temperature control device 500 may also include a first fan 55 and a second fan 56. Both the first fan 55 and the second fan 56 can rotate in both directions, thereby changing the direction of airflow. The first fan 55 is disposed in the first air duct 501, and the second fan 56 is disposed in the second air duct 502. When the first fan 55 and the second fan 56 are working, both can drive airflow in the ventilation space 53. For example, when the first fan 55 rotates in reverse, it drives air from outside the temperature control device 500 into the ventilation space 53 through the first air duct 501.

[0114] Furthermore, both the first air duct 501 and the second air duct 502 are normally open, and both the first air duct 501 and the second air duct 502 are connected to the vehicle passenger compartment, so that the air in the vehicle passenger compartment can flow into the ventilation space 53 along the first air duct 501 and the second air duct 502 respectively, or the air in the ventilation space 53 can flow into the vehicle passenger compartment along the first air duct 501 and the second air duct 502 respectively.

[0115] Furthermore, such as Figure 2 and Figure 3As shown, the temperature control device 500 may also have a first mode damper 57 and a second mode damper 58. The first mode damper 57 is located in the third air duct 503 and can be selectively opened or closed, achieving the effect of selectively connecting the third air duct 503 with the outside of the temperature control device 500. The second mode damper 58 is located in the fourth air duct 504 and can be selectively opened or closed, achieving the effect of selectively connecting the second mode damper 58 with the outside of the temperature control device 500. It should be noted that both the first mode damper 57 and the second mode damper 58 have three connection modes, including: internal circulation mode, external circulation mode, and closed mode.

[0116] In the internal circulation mode, the first mode damper 57 and the second mode damper 58 are in the open state. The first mode damper 57 and the second mode damper 58 are suitable for communicating with the interior of the vehicle passenger compartment, so as to achieve the effect of communicating the ventilation space 53 with the vehicle passenger compartment, so that the air in the vehicle passenger compartment can flow into the ventilation space 53 along the third air duct 503 and the fourth air duct 504 respectively, or the air in the ventilation space 53 can flow into the vehicle passenger compartment along the third air duct 503 and the fourth air duct 504 respectively.

[0117] In external circulation mode, the first mode damper 57 and the second mode damper 58 are in the open state. The first mode damper 57 and the second mode damper 58 are suitable for communicating with the environment, so that the ventilation space 53 is connected with the environment. This allows air in the environment to flow into the ventilation space 53 through the first mode damper 57 and the second mode damper 58, or air in the ventilation space 53 to flow into the environment through the first mode damper 57 and the second mode damper 58.

[0118] In the closed mode, the first mode damper 57 and the second mode damper 58 are closed, and air in the vehicle passenger compartment and the environment cannot flow into the ventilation space 53 from the first mode damper 57 and the second mode damper 58, or air in the ventilation space 53 cannot flow into the vehicle passenger compartment and the environment from the first mode damper 57 and the second mode damper 58.

[0119] Furthermore, such as Figure 2 and Figure 3 As shown, the first air conditioning heat exchanger 17 is disposed in the fourth air duct 504 so that the air flowing through the fourth air duct 504 comes into contact with the first air conditioning heat exchanger 17, thereby achieving the effect of heat exchange between the first air conditioning heat exchanger 17 and the air. The second air conditioning heat exchanger 20 is disposed in the first air duct 501, and the second air conditioning heat exchanger 20 is disposed close to the first fan 55 so that when the first fan 55 drives the air to flow through the second air conditioning heat exchanger 20, the second air conditioning heat exchanger 20 achieves the effect of heat exchange between the second air conditioning heat exchanger 20 and the air.

[0120] Please combine Figure 1 and Figure 2 as well as Figure 3 As shown, according to the thermal management system 1000 of this application, by selectively connecting multiple devices in the thermal management system 1000 and cooperating with the first air conditioning heat exchanger 17, the second air conditioning heat exchanger 20 and the temperature control device 500, the thermal management system 1000 can have multiple working modes, including: passenger cabin cooling mode, dehumidification mode, cooling heat recovery first mode, passenger cabin heating mode, and heating heat recovery first mode.

[0121] Crew cabin cooling mode: such as Figure 4 As shown, when the thermal management system 1000 is in the occupant cabin cooling mode, the heat exchange medium (refrigerant) flows along the first flow path, and the heat exchange medium (coolant) flows along the second flow path, the third flow path and the fifth flow path, thereby reducing the air temperature that exchanges heat with the first air conditioning heat exchanger 17 and reducing the air temperature that exchanges heat with the second air conditioning heat exchanger 20.

[0122] Furthermore, such as Figure 2 As shown, the temperature control device 500 is in temperature control air duct A mode. The first mode damper 57 and the second mode damper 58 are both in the open state. The first mode damper 57 and the second mode damper 58 can be in internal circulation mode or external circulation mode. The first fan 55 and the second fan 56 are both working. When the first mode damper 57 and the second mode damper 58 are in internal circulation mode, the first fan 55 and the second fan 56 can rotate forward and reverse. When the first mode damper 57 and the second mode damper 58 are in external circulation mode, the first fan 55 and the second fan 56 rotate forward, so that air flows from the first mode damper 57 and the second mode damper 58 into the first flow channel 505 and the second flow channel 506 respectively, and flows into the vehicle passenger compartment along the first flow channel 505 and the second flow channel 506.

[0123] Furthermore, as the air flows along the first flow channel 505, it exchanges heat with the second air conditioning heat exchanger 20, thereby reducing the air temperature inside the first flow channel 505. As the air flows along the second flow channel 506, it exchanges heat with the first air conditioning heat exchanger 17, thereby reducing the air temperature inside the second flow channel 506. This allows the cooled air to flow into the vehicle passenger compartment from the first air duct 501 and the second air duct 502, thereby achieving the effect of cooling the passenger compartment.

[0124] Dehumidification mode: such as Figure 5 As shown, when the thermal management system 1000 is in dehumidification mode, the heat exchange medium (refrigerant) flows along the first flow path, and the heat exchange medium (coolant) flows along the second and sixth flow paths, thereby reducing the air temperature that exchanges heat with the first air conditioning heat exchanger 17 and increasing the air temperature that exchanges heat with the second air conditioning heat exchanger 20.

[0125] Furthermore, such as Figure 3 As shown, the temperature control device 500 is in temperature control air duct mode B. The first mode damper 57 is in the closed state, and the second mode damper 58 can be in internal circulation mode or external circulation mode. The first fan 55 rotates forward, and the second fan 56 is closed. Driven by the first fan 55, air flows from the second mode damper 58 into the ventilation space 53 along the fourth air duct 504. The air exchanges heat with the first air conditioning heat exchanger 17 and the second air conditioning heat exchanger 20 in sequence. When the air exchanges heat with the first air conditioning heat exchanger 17, the water vapor in the air is cooled and liquefied, thereby reducing the moisture content in the air and achieving the effect of dehumidification. After dehumidification, the air flows to the second air conditioning heat exchanger 20 for heat exchange, thereby raising the temperature of the dehumidified air to a suitable temperature. This achieves the effect of delivering dehumidified and appropriately priced air to the vehicle passenger compartment, improving the user experience.

[0126] First mode of refrigeration and heat recovery: such as Figure 6 As shown, when the thermal management system 1000 is in the first mode of heat recovery, the heat exchange medium (refrigerant) flows along the first flow path, and the heat exchange medium (coolant) flows along the second and sixth flow paths, thereby reducing the air temperature that exchanges heat with the first air conditioning heat exchanger 17 and increasing the air temperature that exchanges heat with the second air conditioning heat exchanger 20.

[0127] Furthermore, such as Figure 2 As shown, the temperature control device 500 is in temperature control air duct A mode, the first mode damper 57 is in external circulation mode, the second mode damper 58 can be in internal circulation mode or external circulation mode, and the first fan 55 operates in reverse, and the second fan 56 can rotate forward or in reverse. When the second mode damper 58 is in internal circulation mode, the second fan 56 can rotate forward and in reverse. When the second mode damper 58 is in external circulation mode, the second fan 56 rotates forward, so that the air flowing into the ventilation space 53 can flow into the vehicle passenger compartment.

[0128] Furthermore, such as Figure 2 As shown, the second mode damper 58 is in internal circulation mode, and when the second fan 56 is rotating forward, under the driving action of the second fan 56, the air in the vehicle passenger compartment can flow from the second air duct 502 into the second flow channel 506. During the process of the air flowing through the second flow channel 506, the air exchanges heat with the first air conditioning heat exchanger 17, so that the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 absorbs the heat of the air, thereby reducing the temperature of the air exchanging heat with the first air conditioning heat exchanger 17. Furthermore, under the driving action of the second fan 56, the air flows out of the ventilation space 53 from the fourth air duct 504 and flows into the vehicle passenger compartment, thereby achieving the effect of cooling the passenger compartment.

[0129] Furthermore, when the thermal management system 1000 is in the first mode of heat recovery, the air temperature inside the vehicle's passenger compartment is relatively low. Driven by the first fan 55, the air inside the passenger compartment flows from the first air duct 501 into the first flow channel 505. During the flow of the air through the first flow channel 505, the air exchanges heat with the second air conditioning heat exchanger 20, thereby recovering and utilizing the cooling capacity inside the passenger compartment. This allows the air to absorb heat from the heat exchange medium (coolant) inside the second air conditioning heat exchanger 20, thereby reducing the temperature of the heat exchange medium (coolant) inside the second air conditioning heat exchanger 20. This helps to reduce heat loss, save energy, and facilitates the flow of the heat exchange medium (coolant) along the sixth flow path for heat exchange, improving the cooling effect of the thermal management system 1000. Furthermore, driven by the first fan 55, the air that has undergone heat exchange in the second air conditioning heat exchanger 20 flows out of the ventilation space 53 through the first mode damper 57, thus achieving the effect of exhausting air outside the vehicle.

[0130] Crew cabin heating modes: such as Figure 7 As shown, when the thermal management system 1000 is in the passenger compartment heating mode, the heat exchange medium (refrigerant) flows along the fourth flow path, and the heat exchange medium (coolant) flows along the second, third and fifth flow paths, thereby increasing the temperature of the air exchanging heat with the first air conditioning heat exchanger 17 and the air exchanging heat with the second air conditioning heat exchanger 20.

[0131] Furthermore, such as Figure 2 As shown, the temperature control device 500 is in temperature control air duct A mode. The first mode damper 57 and the second mode damper 58 are both in the open state. The first mode damper 57 and the second mode damper 58 can be in internal circulation mode or external circulation mode. The first fan 55 and the second fan 56 are both working. When the first mode damper 57 and the second mode damper 58 are in internal circulation mode, the first fan 55 and the second fan 56 can rotate forward and reverse. When the first mode damper 57 and the second mode damper 58 are in external circulation mode, the first fan 55 and the second fan 56 rotate forward, so that air flows from the first mode damper 57 and the second mode damper 58 into the first flow channel 505 and the second flow channel 506 respectively, and flows into the vehicle passenger compartment along the first flow channel 505 and the second flow channel 506.

[0132] Furthermore, as the air flows along the first flow channel 505, it exchanges heat with the second air conditioning heat exchanger 20, thereby raising the air temperature inside the first flow channel 505. As the air flows along the second flow channel 506, it exchanges heat with the first air conditioning heat exchanger 17, thereby raising the air temperature inside the second flow channel 506. This allows the heated air to flow into the vehicle passenger compartment from the first air duct 501 and the second air duct 502, thereby achieving the effect of heating the passenger compartment.

[0133] Heating and heat recovery first mode: such as Figure 8 As shown, when the thermal management system 1000 is in the first mode of heat recovery, the heat exchange medium (refrigerant) flows along the fourth path, and the heat exchange medium (coolant) flows along the second and sixth paths, thereby increasing the temperature of the air exchanging heat with the first air conditioning heat exchanger 17 and the air exchanging heat with the second air conditioning heat exchanger 20.

[0134] Furthermore, such as Figure 2 As shown, the temperature control device 500 is in temperature control air duct A mode, the first mode damper 57 is in external circulation mode, the second mode damper 58 can be in internal circulation mode or external circulation mode, and the first fan 55 operates in reverse, and the second fan 56 can rotate forward or in reverse. When the second mode damper 58 is in internal circulation mode, the second fan 56 can rotate forward and in reverse. When the second mode damper 58 is in external circulation mode, the second fan 56 rotates forward, so that the air flowing into the ventilation space 53 can flow into the vehicle passenger compartment.

[0135] Furthermore, such as Figure 2 As shown, the second mode damper 58 is in internal circulation mode, and when the second fan 56 is rotating forward, under the driving action of the second fan 56, the air in the vehicle passenger compartment can flow from the second air duct 502 into the second flow channel 506. During the process of the air flowing through the second flow channel 506, the air exchanges heat with the first air conditioning heat exchanger 17, so that the air absorbs the heat of the heat exchange medium (coolant) in the second air conditioning heat exchanger 20, thereby raising the temperature of the air exchanging heat with the first air conditioning heat exchanger 17. Furthermore, under the driving action of the second fan 56, the air flows out of the ventilation space 53 from the fourth air duct 504 and flows into the vehicle passenger compartment, thereby achieving the effect of heating the passenger compartment.

[0136] Furthermore, when the thermal management system 1000 is in the first heating and heat recovery mode, the air temperature inside the vehicle's passenger compartment is relatively high. Driven by the first fan 55, the air inside the passenger compartment flows from the first air duct 501 into the first flow channel 505. During the flow of the air through the first flow channel 505, the air exchanges heat with the second air conditioning heat exchanger 20, thereby recovering and utilizing the heat inside the passenger compartment. This allows the heat exchange medium (coolant) in the second air conditioning heat exchanger 20 to absorb the heat from the air, thereby increasing the temperature of the heat exchange medium (coolant) in the second air conditioning heat exchanger 20. This helps to reduce heat loss, save energy, and facilitates the flow of the heat exchange medium (coolant) along the sixth flow path for heat exchange, improving the heating effect of the thermal management system 1000. Furthermore, driven by the first fan 55, the air that has been heated by the second air conditioning heat exchanger 20 flows out of the ventilation space 53 through the first mode damper 57, thus achieving the effect of exhausting air outside the vehicle.

[0137] In summary, the thermal management system 1000 according to this application has multiple operating modes and can be applied to various working environments, thereby improving the user experience. Furthermore, by applying the heat from the heat exchange medium (coolant) flowing through the first air conditioning heat exchanger 6 and the heat exchange medium (coolant) flowing through the second heat exchanger 4 to the vehicle passenger compartment, the system achieves the effect of cooling or heating the passenger compartment, thus preventing the heat from the heat exchange medium (refrigerant) from affecting the passenger compartment, thereby improving the safety of the thermal management system 1000.

[0138] It should be noted that the heat exchange medium (refrigerant) can be R290 refrigerant. The heat exchange medium (refrigerant) is flammable, and excessive addition of the heat exchange medium (refrigerant) or its entry into the vehicle's passenger compartment can pose a risk to the safety of users. Therefore, according to the thermal management system 1000 of this application, the compressor 1, the first heat exchanger 6, and the second heat exchanger 4 are all located outside the vehicle's passenger compartment. The first heat exchanger 6 and the second heat exchanger 4 achieve heat exchange between the heat exchange medium (refrigerant) and the heat exchange medium (coolant). The heat exchange medium (coolant) exchanges heat with the first air conditioning heat exchanger 17 and the second air conditioning heat exchanger 20, ensuring that the heat from the heat exchange medium (coolant) acts on the vehicle's passenger compartment, preventing the heat from the heat exchange medium (refrigerant) from acting on the passenger compartment, thereby improving the safety of the thermal management system 1000.

[0139] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include: a first control valve 2, the first control valve 2 having a first valve interface 2a, a second valve interface 2b, a third valve interface 2c and a fourth valve interface 2d, the first valve interface 2a being selectively connected to the second valve interface 2b or the third valve interface 2c, the fourth valve interface 2d being selectively connected to the second valve interface 2b or the third valve interface 2c, the first valve interface 2a being connected to a first heat exchange interface 6a, the second valve interface 2b being connected to a compressor outlet 1b, the third valve interface 2c being connected to a compressor inlet 1a, and the fourth valve interface 2d being connected to a third heat exchange interface 4a.

[0140] Furthermore, such as Figure 4 , Figure 5 ,and Figure 6As shown, when the thermal management system 1000 is in occupant cabin cooling mode, dehumidification mode, or cooling and heat recovery first mode, the first valve interface 2a is connected to the third valve interface 2c, and the second valve interface 2b is connected to the fourth valve interface 2d. This achieves the effect of sequentially connecting the compressor 1, the third heat exchange channel, and the first heat exchange channel to form a closed-loop first flow path, allowing the heat exchange medium (refrigerant) to flow along the first flow path. Heat exchange occurs as the heat exchange medium (refrigerant) flows through the third and first heat exchange channels. This facilitates the implementation of occupant cabin cooling mode, dehumidification mode, and cooling and heat recovery first mode.

[0141] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include a gas-liquid separator 3, which is connected between the third valve port 2c and the compressor inlet 1a. Furthermore, since the heat exchange medium (refrigerant) can evaporate to form a gaseous state during the heat absorption process, or it can completely evaporate from a liquid state to a liquid state, or only partially evaporate to form a gaseous state, the gas-liquid separator 3 is used to separate the gaseous and liquid heat exchange medium (refrigerant). By connecting the gas-liquid separator 3 to the third valve port 2c and the compressor inlet 1a, the gaseous heat exchange medium (refrigerant) can flow from the compressor inlet 1a into the compressor 1 for compression, while the liquid heat exchange medium (refrigerant) is stored within the gas-liquid separator 3, thereby ensuring the operational stability of the compressor 1.

[0142] Furthermore, when the liquid heat exchange medium (refrigerant) stored in the gas-liquid separator 3 is heated again, the heat exchange medium (refrigerant) can change from liquid to gas. After the heat exchange medium (refrigerant) changes from liquid to gas, it can flow from the compressor inlet 1a into the compressor 1 for compression processing.

[0143] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include an expansion valve 5, which is connected between the second heat exchange port 6b and the eighth heat exchange port 4c of the third heat exchange channel. Further, the expansion valve 5 may be configured as an electronic expansion valve, the opening of which can be infinitely adjusted to achieve the effects of opening and closing the electronic expansion valve, as well as regulating the flow rate of the electronic expansion valve. This allows the heat exchange medium (refrigerant) to selectively pass through the expansion valve 5, and also achieves the effect of throttling and pressurizing the heat exchange medium (refrigerant) when it flows through the electronic expansion valve 5.

[0144] By connecting the expansion valve 5 between the second heat exchange port 6b and the eighth heat exchange port 4c, the expansion valve 5 can throttle and pressurize the heat exchange medium (refrigerant) flowing between the two ports. Furthermore, by adjusting the opening of the expansion valve 5, the flow rate of the heat exchange medium (refrigerant) between the two ports can be adjusted, and the connection or disconnection between the two ports can be achieved.

[0145] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include: a third drive pump 9, a fourth heat exchange interface 6d adapted to be connected to the heat exchange system 8 of the battery pack, a pump outlet of the third drive pump 9 connected to a fifth heat exchange interface 6c, and a pump inlet of the third drive pump 9 adapted to be connected to the heat exchange system 8.

[0146] Furthermore, the third drive pump 9 can be configured as a water pump, used to drive the flow of the heat exchange medium (coolant). For example... Figure 1 As shown, one end of the heat exchange system 8 is connected to the fourth heat exchange interface 6d, and the other end of the heat exchange system 8 is connected to the fifth heat exchange interface 6c, achieving the effect of parallel connection between the heat exchange system 8 and the second heat exchange channel, so that the heat exchange medium (coolant) circulates between the heat exchange system 8 and the second heat exchange channel. Furthermore, one end of the heat exchange system 8 is connected to the fourth heat exchange interface 6d, and the other end of the heat exchange system 8 is connected to the inlet of the third drive pump 9, and the outlet of the third drive pump 9 is connected to the fifth heat exchange interface 6c, thus achieving the effect of placing the third drive pump 9 between the heat exchange system 8 and the second heat exchange channel, thereby achieving the effect of the third drive pump 9 driving the heat exchange medium (coolant) to circulate between the heat exchange system 8 and the second heat exchange channel, so that the heat exchange system 8 is at a suitable temperature, improving the working stability of the battery pack.

[0147] Therefore, according to the thermal management system 1000 of the present invention, the thermal management system 1000 may further include: a passenger compartment and battery cooling mode and a passenger compartment and battery heating mode.

[0148] Crew cabin and battery cooling modes: such as Figure 9 As shown, when the heat exchange system 8 is connected in parallel with the second flow path, during the flow of the heat exchange medium (coolant) along the second flow path, the heat exchange medium (coolant) in the second flow path can flow to the heat exchange system 8 for heat exchange, and after exchanging heat with the heat exchange system 8, the heat exchange medium (coolant) flows back to the second flow path, thereby achieving the effect of heat exchange between the heat exchange medium (coolant) and the heat exchange system 8, so that the heat exchange medium (coolant) absorbs the heat of the heat exchange system 8, so that the heat exchange system 8 is in a suitable temperature environment, and the working stability of the battery pack is improved.

[0149] Crew cabin and battery heating modes: such as Figure 10 As shown, when the heat exchange system 8 is connected in parallel with the third flow path, during the flow of the heat exchange medium (coolant) along the third flow path, the heat exchange medium (coolant) in the third flow path can flow to the heat exchange system 8 for heat exchange, and after the heat exchange medium (coolant) exchanges heat with the heat exchange system 8, it flows back to the third flow path, thereby achieving the effect of heat exchange between the heat exchange medium (coolant) and the heat exchange system 8, so that the heat exchange system 8 absorbs the heat of the heat exchange medium (coolant), so that the heat exchange system 8 is in a suitable temperature environment, and improves the working stability of the battery pack.

[0150] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include a proportional regulating valve 10, which has selectively connected first proportional connection port 10a, second proportional connection port 10b, and third proportional connection port 10c. The first proportional connection port 10a is adapted to communicate with the heat exchange system 8, the second proportional connection port 10b is connected to the fourth heat exchange interface 6d, and the third proportional connection port 10c is connected to the outlet of the third drive pump 9. Further, the proportional regulating valve 10 may be configured as a proportional electromagnetic regulating valve, where the opening sizes of the first proportional connection port 10a, second proportional connection port 10b, and third proportional connection port 10c can be adjusted respectively, thereby achieving adjustment of the flow rates of the heat exchange medium flowing through the first proportional connection port 10a, second proportional connection port 10b, and third proportional connection port 10c, and thus controlling the flow rate of the heat exchange medium flowing through the first proportional connection port 10a, second proportional connection port 10b, and third proportional connection port 10c.

[0151] Furthermore, such as Figure 4 and Figure 9 As shown, the first proportional connection port 10a is selectively connected to either the second proportional connection port 10b or the third proportional connection port 10c. This can be understood as the first proportional connection port 10a being connected to the second proportional connection port 10b, or the first proportional connection port 10a being connected to the third proportional connection port 10c. When the first proportional connection port 10a is connected to the second proportional connection port 10b, the heat exchange system 8 is connected to the fourth heat exchange interface 6d. When the first proportional connection port 10a is disconnected from the second proportional connection port 10b, the heat exchange system 8 is disconnected from the fourth heat exchange interface 6d. This achieves the effect of selectively connecting the heat exchange system 8 in parallel with the second flow path, or selectively connecting the heat exchange system 8 in parallel with the third flow path. This further enables the switching between the occupant cabin cooling mode and the occupant cabin and battery cooling mode, as well as the switching between the occupant cabin heating mode and the occupant cabin and battery heating mode.

[0152] Furthermore, such as Figure 9 and Figure 10As shown, when the first proportional connection port 10a is connected to the second proportional connection port 10b, the heat exchange medium (coolant) in the second heat exchange channel flows into the proportional regulating valve 10 from the second proportional connection port 10b and flows into the heat exchange system 8 from the first proportional connection port 10a, so that the heat exchange medium (coolant) exchanges heat with the heat exchange system 8. After the heat exchange medium (coolant) has completed the heat exchange, it flows into the third drive pump 9 from the inlet. Since the outlet of the third drive pump 9 is connected to both the fifth heat exchange interface 6c and the third proportional connection port 10c, the heat exchange medium (coolant) can flow into the fifth heat exchange interface 6c and the third proportional connection port 10c respectively, so as to achieve the effect of the heat exchange medium (coolant) flowing back into the second heat exchange channel and the effect of the heat exchange medium (coolant) flowing back into the heat exchange system 8.

[0153] Furthermore, such as Figure 9 and Figure 10 As shown, when the first proportional connection port 10a is connected to the second proportional connection port 10b and the third proportional connection port 10c, the heat exchange medium (coolant) flowing into the proportional regulating valve 10 from the second proportional connection port 10b is mixed with the heat exchange medium (coolant) flowing into the proportional regulating valve 10 from the third proportional connection port 10c. This achieves the effect of regulating the temperature of the heat exchange medium (coolant). When the temperature of the heat exchange medium (coolant) is suitable, the heat exchange effect of the heat exchange medium (coolant) is improved, thereby making the heat exchange system 8 operate in a suitable temperature environment and improving the working stability of the battery pack.

[0154] Furthermore, since the opening sizes of the first proportional connection port 10a, the second proportional connection port 10b, and the third proportional connection port 10c can all be adjusted, the flow rate of the heat exchange medium (coolant) flowing into the proportional regulating valve 10 from the second proportional connection port 10b and the flow rate of the heat exchange medium (coolant) flowing into the proportional regulating valve 10 from the third proportional connection port 10c can be adjusted. This achieves the effect of regulating the temperature of the heat exchange medium (coolant) flowing into the heat exchange system 8 for heat exchange, making the temperature of the heat exchange medium (coolant) more suitable, further improving the heat exchange effect of the heat exchange medium (coolant), so that the heat exchange system 8 is in a suitable temperature environment, and further improving the working stability of the battery pack.

[0155] In some embodiments of the present invention, such as Figure 1As shown, the thermal management system 1000 may further include a heater 7, which has a heater 7 inlet and a heater 7 outlet. The heater 7 inlet is connected to a fourth heat exchange interface 6d, and the heater 7 outlet is connected to the pump inlet of the first drive pump 16 and a second proportional connection port 10b. Further, when the heater 7 is in operation, it is used to heat the heat exchange medium (coolant). When the heater 7 inlet is connected to the fourth heat exchange interface 6d and the heater 7 outlet is connected to the pump inlet of the first drive pump 16, the heater 7 can heat the heat exchange medium (coolant) flowing from the second heat exchange channel to the first drive pump 16, thereby achieving the effect that the first drive pump 16 delivers the heat exchange medium (coolant) at a suitable temperature to the first air conditioning heat exchanger 17 and the second air conditioning heat exchanger 20. When the heater 7 inlet is connected to the fourth heat exchange port 6d and the heater 7 outlet is connected to the second proportional connection port 10b, the heater 7 can heat the heat exchange medium (coolant) flowing from the second heat exchange channel to the proportional control valve 10, thereby achieving the effect of delivering the heat exchange medium (coolant) at a suitable temperature to the proportional control valve 10.

[0156] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include:

[0157] The second control valve 18 has a fifth valve interface 18a, a sixth valve interface 18b, a seventh valve interface 18c and an eighth valve interface 18d. The fifth valve interface 18a is selectively connected to the sixth valve interface 18b or the eighth valve interface 18d, and the seventh valve interface 18c is selectively connected to the sixth valve interface 18b or the eighth valve interface 18d.

[0158] The third control valve 19 has a ninth valve interface 19a, a tenth valve interface 19b, an eleventh valve interface 19c and a twelfth valve interface 19d, wherein the ninth valve interface 19a is selectively connected to either the tenth valve interface 19b or the twelfth valve interface 19d, and the eleventh valve interface 19c is selectively connected to the twelfth valve interface 19d.

[0159] Specifically, the fifth valve interface 18a is selectively connected to either the radiator inlet 13a or the seventh heat exchange interface 4d; the sixth valve interface 18b is connected to the sixth heat exchange interface 4b; the seventh valve interface 18c is connected to the ninth valve interface 19a; the eighth valve interface 18d is connected to the fourth interface 20b; the tenth valve interface 19b is connected to the fifth heat exchange interface 6c; the eleventh valve interface 19c is selectively connected to the pump outlet of the first drive pump 16; and the twelfth valve interface 19d is connected to the third interface 20a.

[0160] Furthermore, such as Figure 4 , Figure 7 , Figure 9 and Figure 10As shown, when the thermal management system 1000 is in passenger cabin cooling mode, passenger cabin heating mode, passenger cabin and battery cooling mode, or passenger cabin and battery heating mode, the fifth valve interface 18a of the second control valve 18 is connected to the sixth valve interface 18b, and the seventh valve interface 18c is connected to the eighth valve interface 18d. The ninth valve interface 19a of the third control valve 19 is connected to the tenth valve interface 19b, and the eleventh valve interface 19c is connected to the twelfth valve interface 19d. This achieves the effect of the second heat exchange channel, the first drive pump 16, and the second air conditioning heat exchanger 20 sequentially connecting to form a closed loop third flow path, and the effect of the fourth heat exchange channel and the radiator 13 connecting to form a closed loop fifth flow path. This is beneficial for the thermal management system 1000 to have the effects of passenger cabin cooling mode, passenger cabin and battery cooling mode, passenger cabin heating mode, and passenger cabin and battery heating mode.

[0161] Furthermore, such as Figure 5 , Figure 6 and Figure 8 As shown, when the thermal management system 1000 is in dehumidification mode, cooling heat recovery first mode, or heating heat recovery first mode, the fifth valve interface 18a of the second control valve 18 is connected to the eighth valve interface 18d, and the sixth valve interface 18b is connected to the seventh valve interface 18c. The ninth valve interface 19a of the third control valve 19 is connected to the twelfth valve interface 19d, and the tenth valve interface 19b is disconnected from the ninth valve interface 19a, the eleventh valve interface 19c, and the twelfth valve interface 19d. The eleventh valve interface 19c is disconnected from the ninth valve interface 19a and the twelfth valve interface 19d. This achieves the effect of the fourth heat exchange channel, the second air conditioning heat exchanger 20, and the radiator 13 being connected in sequence to form a closed loop sixth flow path, which is beneficial to the thermal management system 1000 having the effects of dehumidification mode, cooling heat recovery first mode, and heating heat recovery first mode.

[0162] In some embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1000 may further include: an on / off valve 21, which is connected between the eleventh valve port 19c and the pump outlet of the first drive pump 16. The on / off valve 21 can open and close to selectively connect or disconnect the eleventh valve port 19c from the first drive pump 16. Figure 4 and Figure 7 As shown, when the on / off valve 21 is open, the eleventh valve port 19c is connected to the pump outlet of the first drive pump 16, so that the heat exchange medium (coolant) flowing out of the pump outlet of the first drive pump 16 can flow into the third control valve 19, thereby facilitating the effect of forming a closed loop third flow path by sequentially connecting the second heat exchange channel, the first drive pump 16, and the second air conditioning heat exchanger 20. Figure 5 , Figure 6 and Figure 8As shown, when the on / off valve 21 is closed, the eleventh valve port 19c is disconnected from the pump outlet of the first drive pump 16, so that the heat exchange medium (coolant) flowing out of the pump outlet of the first drive pump 16 cannot flow into the third control valve 19.

[0163] In some embodiments of the present invention, such as Figure 1 As shown, the heat exchange flow path may further include: a three-way valve 12, which has a selectively connected first three-way valve port 12a, a second three-way valve port 12b, and a third three-way valve port 12c. The first three-way valve port 12a is connected to the seventh heat exchange port 4d, the second three-way valve port 12b is connected to the fifth valve port 18a, and the third three-way valve port 12c is connected to the radiator inlet 13a.

[0164] Furthermore, such as Figure 6 , Figure 8 and Figure 11 , Figure 12 As shown, the second three-way valve interface 12b is selectively connected to the first three-way valve interface 12a and the third three-way valve interface 12c. This can also be understood as the second three-way valve interface 12b being connected to the first three-way valve interface 12a, or the second three-way valve interface 12b being connected to the third three-way valve interface 12c. Further, as... Figure 6 and Figure 8 As shown, when the second three-way valve port 12b is connected to the first three-way valve port 12a, it achieves the effect of connecting the fifth valve port 18a and the seventh heat exchange port 4d. This allows the heat exchange medium (coolant) to flow from the fifth valve port 18a to the seventh heat exchange port 4d without passing through the radiator 13 for heat exchange, thus avoiding heat loss caused by the heat exchange medium (coolant) flowing through the radiator 13. Figure 11 and Figure 12 As shown, when the second three-way valve port 12b is connected to the third three-way valve port 12c, the fifth valve port 18a is connected to the radiator inlet 13a, so that the heat exchange medium (coolant) flows from the fifth valve port 18a to the radiator 13, and the heat exchange medium (coolant) flows through the radiator 13 to exchange heat with the air.

[0165] In some embodiments of the present invention, such as Figure 1 As shown, the heat exchange medium within the heat exchange path is suitable for flowing through the vehicle's motor module 11 to exchange heat with it. Further, as... Figure 1 As shown, one end of the motor module 11 is connected to the seventh heat exchange interface 4d, and the other end of the motor module 11 is connected to the radiator outlet 13b and the first three-way valve interface 12a, as shown. Figure 6 and Figure 8As shown, when the other end of the motor module 11 is connected to the radiator outlet 13b, the heat exchange medium (coolant) first exchanges heat with the air in the radiator 13 during the flow of the heat exchange path. After the heat exchange medium (coolant) completes the heat exchange, it flows from the radiator outlet 13b to the motor module 11, so that the heat exchange medium (coolant) after heat exchange can exchange heat with the motor module 11. Figure 11 and Figure 12 As shown, when the other end of the motor module 11 is connected to the first three-way valve interface 12a, the heat exchange medium (coolant) flows directly from the first three-way valve interface 12a to the motor module 11 during the process of the heat exchange medium (coolant) flowing along the heat exchange flow path, thereby avoiding the heat exchange medium (coolant) flowing through the radiator 13 to exchange heat with the air, and thus avoiding heat loss during the process of heat exchange medium (coolant) exchanging heat with the air.

[0166] In some embodiments of the present invention, such as Figure 6 As shown, when the thermal management system 1000 is in the first mode of cooling and heat recovery, the heat exchange medium (coolant) passes through the second air conditioning heat exchanger 20 along the sixth flow path, thereby reducing the temperature of the heat exchange medium (coolant). When the temperature of the heat exchange medium (coolant) flowing into the second three-way valve port 12b is higher than the ambient temperature (i.e., air temperature), the second three-way valve port 12b is connected to the third three-way valve port 12c. The heat exchange medium (coolant) flows along the sixth flow path to the radiator 13, so that the heat exchange medium (coolant) exchanges heat with the air during the process of flowing through the radiator 13. Since the temperature of the heat exchange medium (coolant) is higher than that of the air, the heat exchange medium (coolant) transfers heat to the air, thereby reducing the temperature of the heat exchange medium (coolant) and further reducing the temperature of the heat exchange medium (coolant) so that the temperature of the heat exchange medium (coolant) is lower than that of the motor module 11. When the heat exchange medium (coolant) exchanges heat with the motor module 11, the heat exchange medium (coolant) can absorb the heat of the motor module 11, thereby reducing the temperature of the motor module 11 and keeping the motor module 11 in a suitable temperature environment, thus improving the working stability of the motor module 11.

[0167] However, as Figure 6 As shown, in the first mode of refrigeration and heat recovery, when the temperature of the heat exchange medium (coolant) flowing into the second three-way valve port 12b is lower than the ambient temperature (i.e., air temperature), such as Figure 11As shown, the three-way valve 12 changes from connecting the second three-way valve port 12b and the third three-way valve port 12c to connecting the second three-way valve port 12b and the first three-way valve port 12a. This allows the thermal management system 1000 to switch from the first cooling and heat recovery mode to the second cooling and heat recovery mode, so that the heat exchange medium (coolant) flows from the first three-way valve port 12a to the motor module 11, thereby preventing the heat exchange medium (coolant) from flowing through the radiator 13 and reducing the impact of air on the temperature of the heat exchange medium (coolant). Therefore, the thermal management system 1000 can also have a second cooling and heat recovery mode, such as... Figure 11 As shown, the thermal management system 1000 is in the second mode of cooling and heat recovery, where the heat exchange medium (coolant) does not flow through the radiator 13 to exchange heat with the air.

[0168] It should be noted that when the temperature of the heat exchange medium (coolant) is lower than the ambient temperature (i.e., the air temperature), if the heat exchange medium (coolant) flows through the radiator 13 and exchanges heat with the air, the heat exchange medium (coolant) can absorb the heat from the air, thereby raising the temperature of the heat exchange medium (coolant), which will be detrimental to the heat exchange of the heat exchange medium (coolant) motor module 11.

[0169] In some embodiments of the present invention, such as Figure 8 As shown, when the thermal management system 1000 is in the first mode of heating and heat recovery, the heat exchange medium (coolant) is heated by the second air conditioning heat exchanger 20, thereby increasing the temperature of the heat exchange medium (coolant). When the temperature of the heat exchange medium (coolant) flowing into the second three-way valve port 12b is lower than the ambient temperature (i.e., air temperature), the second three-way valve port 12b connects with the third three-way valve port 12c. The heat exchange medium (coolant) flows along the sixth flow path to the radiator 13, so that the heat exchange medium (coolant) exchanges heat with the air during the process of flowing through the radiator 13. Since the temperature of the heat exchange medium (coolant) is lower than that of the air, the heat exchange medium (coolant) absorbs the heat of the air, thereby achieving the effect of raising the temperature of the heat exchange medium (coolant). Furthermore, the heat exchange medium (coolant) continues to flow along the sixth flow path to the motor module 11, so that the heat exchange medium (coolant) exchanges heat with the motor module 11. The heat exchange medium (coolant) absorbs the heat of the motor module 11, thereby achieving the effect of raising the temperature of the heat exchange medium (coolant). This facilitates the flow of the heat exchange medium (coolant) along the sixth flow path into the fourth heat exchange channel for heat exchange, thereby improving the stability of the first mode of heating heat recovery.

[0170] However, as Figure 8 As shown, under the first mode of refrigeration and heat recovery, however, as Figure 8 As shown, in the first mode of refrigeration and heat recovery, when the temperature of the heat exchange medium (coolant) flowing into the second three-way valve port 12b is higher than the ambient temperature (i.e., air temperature), such as Figure 12As shown, the three-way valve 12 changes from connecting the second three-way valve port 12b and the third three-way valve port 12c to connecting the second three-way valve port 12b and the first three-way valve port 12a. This achieves the effect of switching the thermal management system 1000 from the first heating and heat recovery mode to the second heating and heat recovery mode, allowing the heat exchange medium (coolant) to flow from the first three-way valve port 12a to the motor module 11, thereby preventing the heat exchange medium (coolant) from flowing through the radiator 13 and reducing the impact of air on the temperature of the heat exchange medium (coolant). Therefore, the thermal management system 1000 can also have a second heating and heat recovery mode, such as... Figure 12 As shown, the thermal management system 1000 is in the second mode of heat recovery, where the heat exchange medium (coolant) does not flow through the radiator 13 to exchange heat with the air.

[0171] It should be noted that when the temperature of the heat exchange medium (coolant) is higher than the ambient temperature (i.e., air temperature), if the heat exchange medium (coolant) flows through the radiator 13 and exchanges heat with the air, the heat exchange medium (coolant) can release heat to the air, thereby reducing the temperature of the heat exchange medium (coolant) so that the temperature of the heat exchange medium (coolant) is too low. This would be detrimental to the flow of the heat exchange medium (coolant) into the fourth heat exchange channel along the sixth flow path for heat exchange, thus improving the stability of the first mode of heat recovery.

[0172] Furthermore, such as Figure 7 , Figure 8 and Figure 12 As shown, when the thermal management system 1000 is in crew cabin heating mode, heating and heat recovery mode one, and heating and heat recovery mode two, in order to ensure effective heat exchange between the heat exchange medium (coolant) in the fourth heat exchange channel and the heat exchange medium (refrigerant) in the third heat exchange channel, the heat exchange medium (coolant) flowing into the fourth heat exchange channel from the seventh heat exchange interface 4d must have a certain temperature. Considering that the crew cabin heating mode, heating and heat recovery mode one, and heating and heat recovery mode two are generally used in cold weather, under cold weather conditions, the heat exchange medium (coolant) is affected by the air temperature, and the temperature of the heat exchange medium (coolant)... Since the temperature is low, it is necessary to determine whether the heat exchange medium (coolant) needs to flow through the radiator 13 for heat dissipation based on the temperature of the heat exchange medium (coolant) to avoid the heat exchange medium (coolant) transferring heat to the air and to ensure the temperature of the heat exchange medium (coolant). In cold weather conditions, the temperature of the heat exchange medium (coolant) is lower than that of the motor module 11. Even if the heat exchange medium (coolant) does not pass through the radiator 13 for heat exchange, the temperature of the heat exchange medium (coolant) is still lower than that of the motor module 11, so that the heat exchange medium (coolant) can absorb heat from the motor module 11, thereby further increasing the temperature of the heat exchange medium (coolant).

[0173] In some embodiments of the present invention, such as Figure 1As shown, the pump inlet of the second drive pump 14 is selectively connected to either the radiator outlet 13b or the first three-way valve interface 12a, and the pump outlet of the second drive pump 14 is connected to the seventh heat exchange interface 4d. Further, as... Figures 4-10 As shown, when the second three-way valve interface 12b is connected to the third three-way valve interface 12c, the pump inlet of the second drive pump 14 is connected to the radiator outlet 13b, and the pump outlet of the second drive pump 14 is connected to the seventh heat exchange interface 4d. This facilitates the realization of the effects of the crew cabin cooling mode, dehumidification mode, first cooling heat recovery mode, crew cabin heating mode, first heating heat recovery mode, crew cabin and battery cooling mode, and crew cabin and battery heating mode.

[0174] Furthermore, such as Figure 11 and 12 As shown, when the second three-way valve interface 12b is connected to the third three-way valve interface 12a, the pump inlet of the second drive pump 14 is connected to the first three-way valve interface 12a, and the pump outlet of the second drive pump 14 is connected to the seventh heat exchange interface 4d, which is beneficial to realizing the effects of the second mode of cooling heat recovery and the second mode of heating heat recovery.

[0175] In some embodiments of the present invention, as shown in the figures, the heat exchange flow path may further include a liquid replenishment device 15, which is used to replenish liquid into the heat exchange flow path. The liquid replenishment device 15 may be constructed as an expansion tank, a container for adding and replenishing the heat exchange medium (coolant), thereby achieving the effect of adding and replenishing the heat exchange medium (coolant) into the heat exchange flow path. Figure 1 As shown, this application uses the example of a liquid replenishment device 15 installed in the heat exchange flow path for illustration. The liquid replenishment device 15 is used to add and replenish the heat medium (coolant) in the heat exchange flow path.
