[0046] In the description of the present application, "a plurality of" means two or more, and "several" means one or more.

[0047] A heat management system 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0048] As shown in the drawings, the heat management system 1 according to an embodiment of the present application includes an air conditioning module 100 and a battery heat exchange module 300. Figures 1-10

[0049] The air conditioning module 100 includes a compressor 110, an indoor heat exchanger 150, an outdoor heat exchanger 140, and a regenerator 200 connected to form a refrigerant circuit, the regenerator 200 being configured to exchange heat with refrigerant flowing to an inlet of the compressor 100 to recover heat, and the battery heat exchange module 300 includes an intermediate heat exchanger 330 having a first heat exchange passage 331 and a second heat exchange passage 332 that exchange heat with each other, the first heat exchange passage 331 being connected to the refrigerant circuit of the air conditioning module 100, and a battery heat exchanger 310 connected to the second heat exchange passage 332 to form a battery heat exchange circuit 340.

[0050] It should be noted that, in Figures 2-10 , the solid line is the flow path of the refrigerant in the air conditioning module 100 and the flow path of the coolant in the battery heat exchange module 300.

[0051] The heat management system 1 according to an embodiment of the present application, by including the air conditioning module 100 having the compressor 110, the indoor heat exchanger 150, the outdoor heat exchanger 140, and the regenerator 200 connected to form the refrigerant circuit, the regenerator 200 being configured to exchange heat with refrigerant flowing to the inlet of the compressor 100 to recover heat.

[0052] In this way, when the air conditioning module 100 is used for indoor heating, the high-temperature and high-pressure refrigerant flowing out of the compressor 110 can flow through the indoor heat exchanger 150 and the outdoor heat exchanger 140 in sequence, the refrigerant can first flow through the indoor heat exchanger 150 and release heat to the indoor through the indoor heat exchanger 150 to increase the indoor temperature, and then the refrigerant can flow back to the compressor 110 after absorbing heat from the outdoor through the outdoor heat exchanger 140; when the air conditioning module 100 is used for indoor cooling, the high-temperature and high-pressure refrigerant flowing out of the compressor 110 can flow through the outdoor heat exchanger 140 and the indoor heat exchanger 150 in sequence, the refrigerant can first flow through the outdoor heat exchanger 140 and release heat to the outdoor through the outdoor heat exchanger 140 to reduce the temperature of the refrigerant, and then the refrigerant can flow through the indoor heat exchanger 150 and absorb heat from the indoor through the indoor heat exchanger 150 to flow back to the compressor to reduce the indoor temperature. ​

[0053] And, by setting the regenerator 200 in the air conditioning module 100, the first end of one passage of the regenerator 200 can be communicated with the vehicle interior heat exchanger 150 or the vehicle exterior heat exchanger 140, and the second end of the passage can be communicated with the vehicle interior heat exchanger 150 or the vehicle exterior heat exchanger 140, while the first end of another passage of the regenerator 200 can be communicated with the vehicle interior heat exchanger 150 or the vehicle exterior heat exchanger 140, and the second end of the passage can be communicated with the inlet 112 of the compressor 110.

[0054] Thus, the refrigerant in one passage of the regenerator 200 can transfer heat to the refrigerant in another passage, thereby increasing the temperature of the refrigerant in the other passage, so that the temperature of the refrigerant returning to the compressor 110 through the regenerator 200 can be increased, and high-temperature and high-pressure refrigerant can be formed after being pressurized by the compressor 110. Moreover, by exchanging heat between the refrigerants in the two passages of the regenerator 200, the heat of the refrigerant in the refrigerant circuit does not need to be released to the outside through the vehicle exterior heat exchanger 140, and the heat of the refrigerant in the refrigerant circuit can be recovered after being exchanged with the refrigerant flowing through the regenerator 200, thereby increasing the energy recovery rate of the thermal management system 1, reducing the energy loss of the thermal management system 1, and improving the energy utilization rate.

[0055] In addition, the battery heat exchange module 300 includes an intermediate heat exchanger 330 and a battery heat exchanger 310 adapted to exchange heat with the battery, the intermediate heat exchanger 330 has a first heat exchange passage 331 and a second heat exchange passage 332 that exchange heat with each other, the first heat exchange passage 331 is connected to the refrigerant circuit of the air conditioning module 100, and the second heat exchange passage 332 is connected with the battery heat exchanger 310 to form a battery heat exchange circuit 340. The battery heat exchange module 300 can also be provided with a water pump 320, which can drive the cooling liquid in the battery heat exchange module 300 to flow, thereby improving the heat exchange efficiency of the battery heat exchange module 300.

[0056] In this way, the refrigerant of the air conditioning module 100 can flow through the first heat exchange passage 331, and the cooling liquid in the battery heat exchange circuit 340 can flow through the second heat exchange passage 332, so that the refrigerant of the air conditioning module 100 and the cooling liquid in the battery heat exchange circuit 340 can exchange heat through the intermediate heat exchanger 330.

[0057] Thus, the battery heat exchange module 300 can first exchange heat with the air conditioning module 100 through the intermediate heat exchanger 330, so that the air conditioning module 100 can absorb the heat of the cooling liquid in the battery heat exchange module 300 through the intermediate heat exchanger 330, thereby reducing the temperature of the cooling liquid in the battery heat exchange module 300, and the cooling liquid in the battery heat exchange module 300 can exchange heat with the battery through the battery heat exchanger 310, thereby absorbing the heat of the battery to cool the battery, avoid the battery temperature being too high, and improve the electrical safety of the battery, further improve the control of the battery temperature, and indirectly cool the battery by the air conditioning module 100, so that the temperature of the battery slowly decreases, improve the protection of the battery, and thus improve the effective driving range of the vehicle.

[0058] Alternatively, the air conditioning module 100 can release heat to the battery heat exchange module 300 through the intermediate heat exchanger 330, thereby increasing the temperature of the cooling liquid in the battery heat exchange module 300, and the cooling liquid in the battery heat exchange module 300 can exchange heat with the battery through the battery heat exchanger 310, thereby releasing heat to the battery to heat the battery, thereby indirectly heating the battery by the air conditioning module 100, so that the temperature of the battery slowly rises, which is beneficial to protect the battery.

[0059] Thus, the heat management system 1 according to the embodiment of the present application not only enables the air conditioning module 100 and the battery heat exchange module 300 to exchange heat, but also has the advantages of high energy utilization rate and high heating efficiency.

[0060] In some specific embodiments of the present application, the heat management system 1 has at least an air conditioning refrigeration state, and the refrigerant at the inlet 112 of the flow compressor 110 in the regenerator 200 is exchanged to recover heat when the heat management system 1 is in the air conditioning refrigeration state. In this way, when the heat management system 1 is in the air conditioning refrigeration state, the refrigerant will flow through the regenerator 200 to further increase the temperature of the refrigerant before flowing back to the compressor 110, so that the liquid droplets carried in the return gas flowing to the compressor 110 are gasified, preventing the compressor 110 from producing liquid hammer, and ensuring that the heat in the refrigerant circuit can be effectively recovered when the heat management system 1 is in the air conditioning refrigeration state, which is beneficial to improve the energy recovery rate and reduce the energy loss of the heat management system 1.

[0061] Further, the heat management system 1 has at least a switchable air conditioning cooling state and an air conditioning heating state. In the air conditioning cooling state and the air conditioning heating state, the refrigerant flowing to the inlet 112 of the compressor 110 in the regenerator 200 is exchanged to recover heat. In this way, no matter whether the heat management system 1 is in the air conditioning cooling state or the air conditioning heating state, the refrigerant will flow through the regenerator 200 to further increase the temperature of the refrigerant before flowing back to the compressor 110, so that the liquid droplets entrained in the back gas flowing to the compressor 110 are gasified to prevent the compressor 110 from being subjected to liquid strike. Moreover, no matter whether the heat management system 1 is in the air conditioning cooling state or the air conditioning heating state, the refrigerant in the two passages of the regenerator 200 will be exchanged, that is, the heat of the refrigerant in the refrigerant circuit will be transferred to the refrigerant flowing through the regenerator 200, so that the heat in the refrigerant circuit can be effectively recovered when the heat management system 1 is in the air conditioning cooling state and the air conditioning heating state, which is beneficial to improve the energy recovery rate and reduce the energy loss of the heat management system 1.

[0062] Further, as long as the compressor 110 is running, the refrigerant flowing to the inlet 112 of the compressor 110 in the regenerator 200 is exchanged to recover heat. That is, no matter what state the heat management system 1 is in, as long as the compressor 110 is running, the regenerator 200 will heat the refrigerant flowing therethrough, further improving the energy recovery rate of the heat management system 1, more effectively reducing the energy loss of the heat management system 1, and gasifying the liquid droplets entrained in the back gas to avoid the problem of liquid strike of the compressor 110, so that the gas entering the compressor 110 becomes superheated steam, reducing harmful overheating.

[0063] According to some embodiments of the present application, the vehicle heat exchanger 150 includes a first vehicle heat exchanger 120 and a second vehicle heat exchanger 130, the first end of the first vehicle heat exchanger 120 is in communication with the outlet 111 of the compressor 110, the first end of the second vehicle heat exchanger 130 and the first end of the vehicle heat exchanger 140 are both in communication with the second end of the first vehicle heat exchanger 120, and the regenerator 200 has a first passage 210 and a second passage 220 that exchange heat with each other. In some embodiments of the present application and subsequent embodiments, the first passage 210 of the regenerator is taken as a high-pressure passage 210, and the second passage 220 is taken as a low-pressure passage 220. The first end of the high-pressure passage 210 is optionally in communication with the second end of the second vehicle heat exchanger 130 and the second end of the vehicle heat exchanger 140, the second end of the high-pressure passage 210 is optionally in communication with the first end of the second vehicle heat exchanger 130 and the first end of the vehicle heat exchanger 140, the first end of the low-pressure passage 220 is optionally in communication with the second end of the second vehicle heat exchanger 130 and the second end of the vehicle heat exchanger 140, and the second end of the low-pressure passage 220 is in communication with the inlet 112 of the compressor 110.

[0064] The gas-liquid separator 700 can separate the gas and liquid of the refrigerant to make the refrigerant returning to the compressor 110 all be gaseous refrigerant, so as to ensure the stable suction of the compressor 110. In addition, the refrigerant in the air conditioning module 100 of the heat management system 1 can be carbon dioxide (CO2), and the cooling liquid in the battery heat exchange module 300 can be water.

[0065] The first end of the first vehicle heat exchanger 120 is communicated with the outlet 111 of the compressor 110, and the first end of the second vehicle heat exchanger 130 and the first end of the vehicle heat exchanger 140 are both communicated with the second end of the first vehicle heat exchanger 120.

[0066] That is, the high-temperature and high-pressure refrigerant flowing out of the compressor 110 can first flow through the first vehicle heat exchanger 120, and then the refrigerant flowing out of the first vehicle heat exchanger 120 can flow to the second vehicle heat exchanger 130 or the vehicle heat exchanger 140. When the air conditioning module 100 is used for cooling the vehicle, the refrigerant can flow to the vehicle heat exchanger 140 through the first vehicle heat exchanger 120, and then the refrigerant can be cooled by the vehicle heat exchanger 140 and then absorb the heat in the vehicle through the second vehicle heat exchanger 130 to cool the vehicle. When the air conditioning module 100 is used for heating the vehicle, the refrigerant can first flow through the first vehicle heat exchanger 120, and then the refrigerant can be heated by the first vehicle heat exchanger 120 and then heated by the second vehicle heat exchanger 130 to further release the heat of the refrigerant, so that the heat exchange between the refrigerant and the air in the vehicle is more sufficient. In addition, the first vehicle heat exchanger 120 and the second vehicle heat exchanger 130 can be used for heating the vehicle at the same time, so that the heating effect of the air conditioning module 100 is better, and the heating efficiency is higher.

[0067] In addition, the regenerator 200 has the high-pressure channel 210 and the low-pressure channel 220 which exchange heat with each other. The first end of the high-pressure channel 210 is selectively communicated with the second end of the second vehicle heat exchanger 130 and the second end of the vehicle heat exchanger 140, the second end of the high-pressure channel 210 is selectively communicated with the first end of the second vehicle heat exchanger 130 and the first end of the vehicle heat exchanger 140, the first end of the low-pressure channel 220 is selectively communicated with the second end of the second vehicle heat exchanger 130 and the second end of the vehicle heat exchanger 140, and the second end of the low-pressure channel 220 is communicated with the inlet 112 of the compressor 110.

[0068] Thus, the refrigerant in the high-pressure passage 210 can transfer heat to the refrigerant in the low-pressure passage 220, thereby increasing the temperature of the refrigerant in the low-pressure passage 220, so that the temperature of the refrigerant returning to the compressor 110 through the low-pressure passage 220 is high, and the refrigerant can be formed into high-temperature and high-pressure refrigerant after being pressurized by the compressor 110. Moreover, by exchanging heat between the refrigerant in the high-pressure passage 210 and the refrigerant in the low-pressure passage 220, the heat of the refrigerant in the high-pressure passage 210 does not need to be released to the outside through the vehicle external heat exchanger 140, and the heat of the refrigerant in the high-pressure passage 210 can be recovered after being exchanged with the refrigerant in the low-pressure passage 220, thereby improving the energy recovery rate of the thermal management system 1 and reducing the energy loss of the thermal management system 1, and the energy utilization rate is higher.

[0069] Moreover, when the air conditioning module 100 is for vehicle interior refrigeration, the refrigerant can flow through the first vehicle interior heat exchanger 120, the vehicle external heat exchanger 140, the high-pressure passage 210 of the regenerator 200, the second vehicle interior heat exchanger 130, and the low-pressure passage 220 of the regenerator 200 in sequence and return to the compressor 110, and the coolant in the high-pressure passage 210 of the regenerator 200 can transfer heat to the refrigerant in the low-pressure passage 220 of the regenerator 200. When the air conditioning module 100 is for vehicle interior heating, the refrigerant can flow through the first vehicle interior heat exchanger 120, the high-pressure passage 210 of the regenerator 200, the vehicle external heat exchanger 140, and the low-pressure passage 220 of the regenerator 200 in sequence and return to the compressor 110, and the coolant in the high-pressure passage 210 of the regenerator 200 can transfer heat to the refrigerant in the low-pressure passage 220 of the regenerator 200.

[0070] That is, no matter whether the thermal management system 1 is in the air conditioning refrigeration state or the air conditioning heating state, the refrigerant will flow through the regenerator 200, and the refrigerant in the high-pressure passage 210 and the refrigerant in the low-pressure passage 220 of the regenerator 200 will exchange heat, thereby ensuring that the heat in the refrigerant circuit can be effectively recovered when the thermal management system 1 is in the air conditioning refrigeration state and the air conditioning heating state, further improving the energy recovery rate to reduce the energy loss of the thermal management system 1.

[0071] In some embodiments of the present application, as shown in Figure 1 The thermal management system 1 further includes a first on-off valve 400, a second on-off valve 410, a third on-off valve 420, a fourth on-off valve 430, a fifth on-off valve 440, and a sixth on-off valve 450.

[0072] The first on-off valve 400 is connected between the second end of the first vehicle heat exchanger 120 and the first end of the second vehicle heat exchanger 130, the second on-off valve 410 is connected between the second end of the first vehicle heat exchanger 120 and the first end of the vehicle external heat exchanger 140, the third on-off valve 420 is connected between the second end of the vehicle external heat exchanger 140 and the first end of the high-pressure passage 210, the fourth on-off valve 430 is connected between the second end of the vehicle external heat exchanger 140 and the first end of the low-pressure passage 220, the fifth on-off valve 440 is connected between the second end of the second vehicle heat exchanger 130 and the first end of the high-pressure passage 210, and the sixth on-off valve 450 is connected between the second end of the second vehicle heat exchanger 130 and the first end of the low-pressure passage 220.

[0073] Thus, by adjusting the opening and closing of the first on-off valve 400 and the second on-off valve 410, the flow direction of the refrigerant flowing through the first vehicle heat exchanger 120 can be controlled to flow to the second vehicle heat exchanger 130 or to the vehicle external heat exchanger 140, so that the refrigerant can be controlled to release heat to the vehicle interior through the second vehicle heat exchanger 130 or to release heat to the vehicle exterior through the vehicle external heat exchanger 140.

[0074] And by adjusting the opening and closing of the third on-off valve 420 and the fourth on-off valve 430, the flow direction of the refrigerant flowing through the vehicle external heat exchanger 140 can be controlled to flow to the high-pressure passage 210 or to the low-pressure passage 220, so that when the temperature of the refrigerant flowing through the vehicle external heat exchanger 140 is still high, the refrigerant can be directed to the high-pressure passage 210 to exchange heat with the refrigerant in the low-pressure passage 220, so as to realize energy recovery and reduce the temperature of the refrigerant in the high-pressure passage 210, and when the temperature of the refrigerant flowing through the vehicle external heat exchanger 140 is already low, the refrigerant can be directly directed to the low-pressure passage 220, and after the refrigerant in the low-pressure passage 220 is heated by the refrigerant in the high-pressure passage 210, the refrigerant in the low-pressure passage 220 can become high-temperature refrigerant and return to the compressor 110.

[0075] In addition, by adjusting the opening and closing of the fifth on-off valve 440 and the sixth on-off valve 450, the flow direction of the refrigerant flowing through the second vehicle heat exchanger 130 can be controlled to flow to the high-pressure passage 210 or to the low-pressure passage 220, so that when the temperature of the refrigerant flowing through the second vehicle heat exchanger 130 is still high, the refrigerant can be directed to the high-pressure passage 210 to exchange heat with the refrigerant in the low-pressure passage 220, so as to realize energy recovery and reduce the temperature of the refrigerant in the high-pressure passage 210, and when the temperature of the refrigerant flowing through the second vehicle heat exchanger 130 is already low, the refrigerant can be directly directed to the low-pressure passage 220, and after the refrigerant in the low-pressure passage 220 is heated by the refrigerant in the high-pressure passage 210, the refrigerant in the low-pressure passage 220 can become high-temperature refrigerant and return to the compressor 110.

[0076] In some embodiments of the present application, as shown inFigure 1 As shown, the thermal management system 1 further comprises a first throttling device 500 and a second throttling device 510.

[0077] The first throttling device 500 is connected between the second end of the high-pressure passage 210 and the first end of the external heat exchanger 140, so that the high-temperature and high-pressure refrigerant can become low-temperature and low-pressure refrigerant after throttling by the first throttling device 500 after the temperature of the refrigerant passing through the high-pressure passage 210 is lowered, at which time the external heat exchanger 140 acts as an evaporator, and the refrigerant flowing through the external heat exchanger 140 can absorb heat from the outside of the vehicle through the external heat exchanger 140, thereby heating the refrigerant using the heat from the outside of the vehicle to make the refrigerant become high-temperature refrigerant again and then return to the compressor 110.

[0078] The second throttling device 510 is connected between the second end of the high-pressure passage 210 and the first end of the second internal heat exchanger 130, so that the high-temperature and high-pressure refrigerant can become low-temperature and low-pressure refrigerant after throttling by the second throttling device 510 after the temperature of the refrigerant passing through the high-pressure passage 210 is lowered, at which time the second internal heat exchanger 130 acts as an evaporator, and the refrigerant flowing through the second internal heat exchanger 130 can absorb heat from the inside of the vehicle through the second internal heat exchanger 130, thereby reducing the temperature inside the vehicle to achieve refrigeration inside the vehicle.

[0079] Further, as shown in Figure 2 and Figure 3 The thermal management system 1 has at least a switchable air conditioning refrigeration state and an air conditioning heating state, and in the air conditioning refrigeration state and the air conditioning heating state, the refrigerant in the low-pressure passage 220 of the regenerator 200 is in heat exchange with the refrigerant in the high-pressure passage 210.

[0080] Specifically, as shown in Figure 2 The thermal management system 1 is in the air conditioning refrigeration state, the first on-off valve 400, the fourth on-off valve 430 and the fifth on-off valve 440 are closed, and the second on-off valve 410, the third on-off valve 420 and the sixth on-off valve 450 are opened.

[0081] In this way, after the refrigerant flows out of the compressor 110, it can flow sequentially through the first in-vehicle heat exchanger 120, the second on / off valve 410, and the external heat exchanger 140. At this time, the first in-vehicle heat exchanger 120 acts as a pipeline, meaning that the first in-vehicle heat exchanger 120 releases almost no heat or very little heat into the vehicle, and the refrigerant can mainly release heat to the outside through the external heat exchanger 140, which acts as a condenser. Then, the refrigerant flows through the third on / off valve 420 and the first end of the high-pressure channel 210 to the high-pressure channel 210. After heat exchange between the refrigerant in the high-pressure channel 210 and the low-pressure channel 220, the temperature of the refrigerant flowing out from the second end of the high-pressure channel 210 decreases again. Next, the refrigerant passes through the second throttling element 510. After flowing, the refrigerant becomes a low-temperature, low-pressure refrigerant. At this time, the refrigerant flows through the second in-vehicle heat exchanger 130 to absorb heat from the vehicle interior. The second in-vehicle heat exchanger 130 acts as an evaporator, thereby reducing the temperature inside the vehicle and achieving cooling. Finally, the refrigerant flows from the second in-vehicle heat exchanger 130 and the sixth shut-off valve 450 into the low-pressure channel 220. After exchanging heat with the refrigerant in the high-pressure channel 210 in the low-pressure channel 220 and becoming warmer, it flows back to the compressor 110, realizing the cooling cycle of the air conditioning module 100. When the thermal management system 1 is in the air conditioning cooling state, the thermal management system 1 can blow cold air out by blowing it towards the passenger vents or towards the vents of the windows and windshield.

[0082] In addition, such as Figure 3 As shown, the thermal management system 1 is in air conditioning heating mode, with the second on / off valve 410, the third on / off valve 420 and the sixth on / off valve 450 closed, and the first on / off valve 400, the fourth on / off valve 430 and the fifth on / off valve 440 open.

[0083] In this way, the refrigerant can flow through the first vehicle interior heat exchanger 120, the first on-off valve 400 and the second vehicle interior heat exchanger 130 in sequence after flowing out of the compressor 110, at this time, the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130 both act as condensers, the refrigerant is sequentially heat-absorbed by the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130, thereby the temperature in the vehicle can be increased, the heating in the vehicle is realized, then the refrigerant flows out of the second vehicle interior heat exchanger 130 and sequentially flows through the fifth on-off valve 440, the high-pressure channel 210, the first throttling component 500 and the vehicle exterior heat exchanger 140, after the refrigerant exchanges heat with the refrigerant in the low-pressure channel 220 through the high-pressure channel 210, the temperature of the refrigerant is lowered again, and the refrigerant becomes low-temperature and low-pressure refrigerant after throttling through the first throttling component 500, finally, the refrigerant flows back to the compressor 110 through the vehicle exterior heat exchanger 140, the fourth on-off valve 430 and the low-pressure channel 220, the refrigerant can absorb the heat outside the vehicle through the vehicle exterior heat exchanger 140, the vehicle exterior heat exchanger 140 acts as an evaporator, and the heat in the high-pressure channel 210 is absorbed through the low-pressure channel 220, so that the refrigerant exchanges heat with the refrigerant in the high-pressure channel 210 in the low-pressure channel 220 to be heated and then flows back to the compressor 110, realizing the heating cycle of the air conditioning module 100, wherein, when the thermal management system 1 is in the air conditioning heating state, the thermal management system 1 can perform hot air blowing through the air outlet blowing to the passenger or the air outlet blowing to the vehicle window and windshield.

[0084] In some embodiments of the present application, the thermal management system 1 has at least one of an air conditioning heating defogging state and a dehumidifying state, in the air conditioning heating defogging state and the dehumidifying state, the refrigerant in the low-pressure channel 220 of the heat regenerator 200 exchanges heat with the refrigerant in the high-pressure channel 210.

[0085] When the thermal management system 1 is in the air conditioning heating defogging state, the second on-off valve 410, the third on-off valve 420 and the sixth on-off valve 450 are closed, and the first on-off valve 400, the fourth on-off valve 430 and the fifth on-off valve 440 are opened, the air conditioning module 100 can also defog the vehicle, it can be understood that at this time, the refrigerant flowing through the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130 can be sequentially heat-absorbed, the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130 act as condensers, the low-temperature air in the vehicle can be heated to high-temperature air through the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130, thereby the high-temperature air can be used for defogging in the vehicle, wherein, when the thermal management system 1 is in the defogging state, the thermal management system 1 can perform hot air blowing through the air outlet blowing to the vehicle window and windshield, thereby the high-temperature air can be used for defogging the glass.

[0086] When the heat management system 1 is in the dehumidification state, the first on-off valve 400, the fourth on-off valve 430 and the fifth on-off valve 440 are closed, and the second on-off valve 410, the third on-off valve 420 and the sixth on-off valve 450 are opened, the air conditioning module 100 can also dehumidify the vehicle interior, and it can be understood that at this time the second vehicle interior heat exchanger 130 can act as an evaporator, and the high-humidity air in the vehicle interior can be cooled after passing through the second vehicle interior heat exchanger 130 to condense water, thereby reducing the moisture content of the air, and the air is mixed with other air in the vehicle interior, thereby reducing the humidity of the air in the vehicle interior, wherein when the heat management system 1 is in the dehumidification state, the heat management system 1 can also dehumidify by blowing air to the air outlet of the passenger or to the air outlet of the vehicle window and windshield.

[0087] In some embodiments of the present application, as shown in Figure 1 The heat management system 1 further comprises a seventh on-off valve 460 and an eighth on-off valve 470.

[0088] The seventh on-off valve 460 is connected between the outlet 111 of the compressor 110 and the first end of the intermediate heat exchanger 330, the sixth on-off valve 450 is connected between the second end of the intermediate heat exchanger 330 and the first end of the low-pressure channel 220, and the fifth on-off valve 440 is connected between the second end of the intermediate heat exchanger 330 and the first end of the high-pressure channel 210.

[0089] In this way, when the heat management system 1 heats the battery, the refrigerant can flow through the seventh on-off valve 460, the intermediate heat exchanger 330, the fifth on-off valve 440 and the high-pressure channel 210 in turn, and then flow back to the compressor 110 through the fourth on-off valve 430 and the low-pressure channel 220 after absorbing the heat outside the vehicle through the vehicle exterior heat exchanger 140, to realize the heating cycle of the battery; and when the heat management system 1 cools the battery, the refrigerant can be heated after flowing through the sixth on-off valve 450 and the low-pressure channel 220 after being cooled by the vehicle exterior heat exchanger 140, and then flowing back to the compressor 110 to realize the cooling cycle of the battery.

[0090] And the eighth on-off valve 470 is connected between the second end of the high-pressure channel 210 and the first end of the intermediate heat exchanger 330, so that when the refrigerant flows out from the second end of the high-pressure channel 210, the refrigerant can be controlled not to flow to the intermediate heat exchanger 330 by closing the eighth on-off valve 470, so that the refrigerant can flow through the vehicle exterior heat exchanger 140 to absorb the heat outside the vehicle, to realize the normal working cycle of the heat management system 1.

[0091] In some embodiments of the present application, as shown in Figure 1 The heat management system 1 further comprises a third throttling device 520.

[0092] The third throttling member 520 is arranged between the second end of the high-pressure passage 210 and the first end of the intermediate heat exchanger 330 and between the outlet 111 of the compressor 110 and the first end of the intermediate heat exchanger 330. Thus, the refrigerant cooled in the high-pressure passage 210 can be throttled and cooled again by the third throttling member 520, so that the refrigerant can become low-temperature and low-pressure refrigerant, and then the low-temperature and low-pressure refrigerant can be used to cool the battery.

[0093] Further, as shown in Figure 4 and Figure 5 , the thermal management system 1 has at least one of a battery heating state and a battery cooling state, and in the battery heating state and the battery cooling state, the refrigerant in the low-pressure passage 220 of the heat exchanger 200 is in heat exchange with the refrigerant in the high-pressure passage 210.

[0094] Specifically, as shown in Figure 4 , the thermal management system 1 is in the battery heating state, the first on-off valve 400, the second on-off valve 410, the third on-off valve 420, the sixth on-off valve 450, and the eighth on-off valve 470 are closed, and the fourth on-off valve 430, the fifth on-off valve 440, and the seventh on-off valve 460 are opened.

[0095] Thus, the refrigerant flows out of the outlet 111 of the compressor 110 and then flows through the seventh on-off valve 460 and the intermediate heat exchanger 330 in sequence, and then exchanges heat with the battery through the intermediate heat exchanger 330 to increase the temperature of the battery. The intermediate heat exchanger 330 acts as a condenser, and then the refrigerant flows to the high-pressure passage 210 through the fifth on-off valve 440, is cooled in the high-pressure passage 210, and then flows to the vehicle external heat exchanger 140 through the first throttling member 500. The refrigerant absorbs heat through the vehicle external heat exchanger 140, and then flows to the low-pressure passage 220 through the fourth on-off valve 430. The vehicle external heat exchanger 140 acts as an evaporator, and finally the refrigerant is heated in the low-pressure passage 220 to become high-temperature refrigerant and then flows back to the compressor 110, realizing the battery heating cycle.

[0096] In addition, as shown in Figure 5 , the thermal management system 1 is in the battery cooling state, the first on-off valve 400, the fourth on-off valve 430, the fifth on-off valve 440, and the seventh on-off valve 460 are closed, and the second on-off valve 410, the third on-off valve 420, the sixth on-off valve 450, and the eighth on-off valve 470 are opened.

[0097] In this way, the refrigerant flows out of the outlet 111 of the compressor 110 and then flows through the first indoor heat exchanger 120, the second on-off valve 410, the outdoor heat exchanger 140, the third on-off valve 420 and the high-pressure passage 210 in sequence, at this time, the first indoor heat exchanger 120 acts as a pipeline, that is, the first indoor heat exchanger 120 almost does not release heat to the indoor or releases less heat to the indoor, the refrigerant mainly releases heat to the outdoor through the outdoor heat exchanger 140, the outdoor heat exchanger 140 acts as a condenser, and then the refrigerant exchanges heat with the refrigerant in the high-pressure passage 210 and the low-pressure passage 220 to be cooled, and then the refrigerant flows through the eighth on-off valve 470, the third throttling device 520 and the intermediate heat exchanger 330 in sequence from the second end of the high-pressure passage 210, the refrigerant throttled by the third throttling device 520 becomes low-temperature and low-pressure refrigerant, and then the refrigerant can exchange heat with the battery through the intermediate heat exchanger 330 to reduce the temperature of the battery, the intermediate heat exchanger 330 acts as an evaporator, and finally, the refrigerant flows to the low-pressure passage 220 through the sixth on-off valve 450, exchanges heat with the refrigerant in the high-pressure passage 210 in the low-pressure passage 220 to be warmed, and then flows back to the compressor 110, so as to realize the cooling cycle of the battery.

[0098] In some embodiments of the present application, as shown in Figures 6-9 The heat management system 1 has at least one of an air-heat-electricity-cooling state, a first air-cooling-electricity-heating state, an air-heat-electricity-heating state and an air-cooling-electricity-cooling state. It should be noted that the air-heat-electricity-cooling state of the heat management system 1 means that the heat management system 1 is heating in the vehicle and the battery is cooling, the air-cooling-electricity-heating state means that the heat management system 1 is cooling in the vehicle and the battery is heating, the air-heat-electricity-heating state means that the heat management system 1 is heating in the vehicle and the battery is heating, and the air-cooling-electricity-cooling state means that the heat management system 1 is cooling in the vehicle and the battery is cooling. In the air-heat-electricity-cooling state, the first air-cooling-electricity-heating state, the air-heat-electricity-heating state and the air-cooling-electricity-cooling state, the refrigerant in the low-pressure passage 220 of the regenerator 200 exchanges heat with the refrigerant in the high-pressure passage 210.

[0099] As shown in Figure 6 The heat management system 1 is in the air-heat-electricity-cooling state, the first on-off valve 400, the fourth on-off valve 430, the fifth on-off valve 440 and the seventh on-off valve 460 are closed, and the second on-off valve 410, the third on-off valve 420, the sixth on-off valve 450 and the eighth on-off valve 470 are opened.

[0100] In this way, after the refrigerant flows out of the outlet 111 of the compressor 110, it can release heat into the vehicle through the first in-vehicle heat exchanger 120, thereby increasing the temperature inside the vehicle and achieving in-vehicle heating. The first in-vehicle heat exchanger 120 acts as a condenser. Then, the refrigerant flows out of the first in-vehicle heat exchanger 120 and flows sequentially through the second on-off valve 410, the external heat exchanger 140, the third on-off valve 420, the high-pressure channel 210, the eighth on-off valve 470, the third throttling element 520, and the intermediate heat exchanger 330. At this time, the external heat exchanger 140 acts as a condenser, and the refrigerant releases heat through the external heat exchanger 140. When the refrigerant passes through the high-pressure channel 210, it exchanges heat with the refrigerant in the low-pressure channel 220 to cool down. Then, after being throttled by the third throttling device 520, it becomes a low-temperature, low-pressure refrigerant. It can then exchange heat with the battery through the intermediate heat exchanger 330 to absorb the battery's heat and lower the battery temperature. The intermediate heat exchanger 330 acts as an evaporator. Finally, the refrigerant flows through the sixth shut-off valve 450 and the low-pressure channel 220. After exchanging heat with the refrigerant in the high-pressure channel 210 through the low-pressure channel 220, it becomes a high-temperature refrigerant and flows back to the compressor 110, realizing the air-thermal-electric cooling cycle for thermal management.

[0101] like Figure 7 As shown, the thermal management system 1 is in the first air-cooled and electric-heated state, with the first on-off valve 400, the second on-off valve 410, the third on-off valve 420, the fourth on-off valve 430 and the eighth on-off valve 470 closed, and the fifth on-off valve 440, the sixth on-off valve 450 and the seventh on-off valve 460 open.

[0102] In this way, after the refrigerant flows out of the compressor 110 outlet 111, it can flow through the seventh shut-off valve 460 to the intermediate heat exchanger 330, and then release heat to the battery through the intermediate heat exchanger 330 to raise the battery temperature. The intermediate heat exchanger 330 acts as a condenser to heat the battery. Then, after the refrigerant flows out of the intermediate heat exchanger 330, it flows sequentially through the fifth shut-off valve 440, the high-pressure channel 210, and the second throttling element 510 to the second in-vehicle heat exchanger 130. When the refrigerant flows through the high-pressure channel 210, it will react with the refrigerant inside the low-pressure channel 220. The refrigerant is cooled by heat exchange, and then becomes a low-temperature, low-pressure refrigerant after being throttled by the second throttling device 510. It can then absorb heat from the vehicle interior through the second in-vehicle heat exchanger 130 to cool the interior. The second in-vehicle heat exchanger 130 acts as an evaporator. Finally, the refrigerant flows out from the second in-vehicle heat exchanger 130, passes through the sixth shut-off valve 450 and the low-pressure channel 220 in sequence, and then flows back to the compressor 110 after heat exchange and temperature increase between the refrigerant in the low-pressure channel 220 and the high-pressure channel 210, thus realizing the first air-cooled electrothermal cycle of the thermal management system 1.

[0103] like Figure 8As shown, the thermal management system 1 is in the air cooling and heating state, the second on-off valve 410, the third on-off valve 420, the sixth on-off valve 450 and the eighth on-off valve 470 are closed, and the first on-off valve 400, the fourth on-off valve 430, the fifth on-off valve 440 and the seventh on-off valve 460 are opened.

[0104] In this way, part of the refrigerant flowing out of the compressor 110 flows to the intermediate heat exchanger 330 through the seventh on-off valve 460, and then the heat can be transferred to the battery through the intermediate heat exchanger 330 to heat the battery, and the intermediate heat exchanger 330 acts as a condenser, and the other part of the refrigerant flows through the first vehicle interior heat exchanger 120, the first on-off valve 400 and the second vehicle interior heat exchanger 130 in turn, and then the heat can be released to the vehicle interior through the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130 in turn, and the first vehicle interior heat exchanger 120 and the second vehicle interior heat exchanger 130 both act as condensers, thereby increasing the temperature of the vehicle interior and achieving heating for the vehicle interior.

[0105] Then, part of the refrigerant flowing out of the intermediate heat exchanger 330 is combined with another part of the refrigerant flowing out of the second vehicle interior heat exchanger 130, and then flows through the fifth on-off valve 440, the high-pressure passage 210, the first throttling device 500 and the vehicle exterior heat exchanger 140. The refrigerant flowing through the vehicle exterior heat exchanger 140 absorbs heat from the outside of the vehicle to increase the temperature of the refrigerant, and the vehicle exterior heat exchanger 140 acts as an evaporator. Finally, the refrigerant flows to the low-pressure passage 220 after passing through the fourth on-off valve 430, and the refrigerant in the low-pressure passage 220 exchanges heat with the refrigerant in the high-pressure passage 210 to become high-temperature refrigerant, and then flows back to the compressor 110, thereby realizing the air cooling and heating cycle of the thermal management system 1.

[0106] As shown, Figure 9 the thermal management system 1 is in the air cooling and heating state, the second on-off valve 410, the third on-off valve 420, the sixth on-off valve 450 and the eighth on-off valve 470 are closed, and the first on-off valve 400, the fourth on-off valve 430, the fifth on-off valve 440 and the seventh on-off valve 460 are opened.

[0107] Thus, the refrigerant flows out of the compressor 110 and then flows through the first vehicle interior heat exchanger 120, the second on-off valve 410, the vehicle exterior heat exchanger 140, the third on-off valve 420 and the high-pressure passage 210 in sequence, at this time, the first vehicle interior heat exchanger 120 acts as a pipeline, that is, the first vehicle interior heat exchanger 120 almost does not release heat to the vehicle interior or releases less heat to the vehicle interior, the refrigerant mainly flows through the vehicle exterior heat exchanger 140 and then releases heat to the vehicle exterior, the vehicle exterior heat exchanger 140 acts as a condenser, and then the refrigerant exchanges heat with the refrigerant in the high-pressure passage 210 and the low-pressure passage 220 and flows out of the second end of the high-pressure passage 210, part of the refrigerant flowing out of the second end of the high-pressure passage 210 flows to the second vehicle interior heat exchanger 130 through the second throttling component 510, the refrigerant throttled by the second throttling component 510 forms low-temperature and low-pressure refrigerant, and absorbs heat in the vehicle interior through the second vehicle interior heat exchanger 130, thereby achieving cooling of the vehicle interior, the second vehicle interior heat exchanger 130 acts as an evaporator, and the other part of the refrigerant flowing out of the second end of the high-pressure passage 210 flows to the intermediate heat exchanger 330 through the eighth on-off valve 470 and the third throttling component 520, the refrigerant throttled by the third throttling component 520 forms low-temperature and low-pressure refrigerant, and absorbs heat of the battery through the intermediate heat exchanger 330, thereby achieving cooling of the battery, the intermediate heat exchanger 330 acts as an evaporator, next, the refrigerant flowing out of the first vehicle interior heat exchanger 120 and the refrigerant flowing out of the intermediate heat exchanger 330 are combined and flow to the low-pressure passage 220 through the sixth on-off valve 450, the refrigerant exchanges heat with the refrigerant in the high-pressure passage 210 in the low-pressure passage 220 to form high-temperature refrigerant, and finally flows back to the compressor 110, thereby realizing the air-cooling and electric-cooling cycle of the thermal management system 1.

[0108] In some embodiments of the present application, as shown in FIG. 6, the thermal management system 1 further has at least a second air-cooling and electric-heating state, in the second air-cooling and electric-heating state, the refrigerant in the low-pressure passage 220 of the regenerator 200 exchanges heat with the refrigerant in the high-pressure passage 210. Figure 10

[0109] When the thermal management system 1 is in the second air-cooling and electric-heating state, the first on-off valve 400, the fourth on-off valve 430 and the eighth on-off valve 470 are closed, and the second on-off valve 410, the third on-off valve 420, the fifth on-off valve 440, the sixth on-off valve 450 and the seventh on-off valve 460 are opened.

[0110] ​In this way, part of the refrigerant flowing out of the outlet 111 of the compressor 110 can flow to the intermediate heat exchanger 330 through the seventh on-off valve 460, and then can be heat-absorbed by the intermediate heat exchanger 330 to increase the temperature of the battery, so as to realize the heating of the battery. The intermediate heat exchanger 330 acts as a condenser. Then, the refrigerant flowing out of the intermediate heat exchanger 330 flows to the fifth on-off valve 440, and another part of the refrigerant flowing out of the outlet 111 of the compressor 110 flows through the first vehicle interior heat exchanger 120, the second on-off valve 410, the vehicle exterior heat exchanger 140 and the third on-off valve 420 in sequence. At this time, the first vehicle interior heat exchanger 120 acts as a pipeline, that is, the first vehicle interior heat exchanger 120 hardly or slightly releases heat to the vehicle interior. The vehicle exterior heat exchanger 140 acts as a condenser, and the refrigerant releases heat to the outside through the vehicle exterior heat exchanger 140. Then, the refrigerant flows to the third on-off valve 420. Part of the refrigerant flowing out of the fifth on-off valve 440 is combined with another part of the refrigerant flowing out of the third on-off valve 420, and then flows to the high-pressure channel 210 together, and then flows to the second vehicle interior heat exchanger 130 through the second throttling component 510. The refrigerant exchanges heat with the refrigerant in the low-pressure channel 220 when flowing through the high-pressure channel 210, and then throttles through the second throttling component 510 to become low-temperature and low-pressure refrigerant. Thus, the refrigerant can absorb heat in the vehicle interior through the second vehicle interior heat exchanger 130 to realize cooling and temperature reduction of the vehicle interior. The second vehicle interior heat exchanger 130 acts as an evaporator. Finally, the refrigerant flowing out of the second vehicle interior heat exchanger 130 flows through the sixth on-off valve 450 and the low-pressure channel 220 in sequence, and then flows back to the compressor 110 after exchanging heat with the refrigerant in the high-pressure channel 210 to increase the temperature, so as to realize the second air-cooled electric heating cycle of the thermal management system 1.

[0111] It can be understood that the difference between the second air-cooled electric heating state and the first air-cooled electric heating state is that the vehicle exterior heat exchanger 140 in the second air-cooled electric heating state also participates in the refrigeration cycle of the vehicle interior. Another part of the refrigerant releases heat to the outside through the vehicle exterior heat exchanger 140, and then is used for refrigeration of the vehicle interior. That is, the intermediate heat exchanger 330 and the vehicle exterior heat exchanger 140 are simultaneously used for refrigeration of the vehicle interior, and the refrigeration effect of the vehicle interior is further improved.

[0112] In some specific embodiments of the present application, as shown in Figure 1 The thermal management system 1 further comprises a fan 600.

[0113] The fan 600 is arranged on the side of the second vehicle interior heat exchanger 130 away from the first vehicle interior heat exchanger 120. The fan 600 guides the airflow to flow through the second vehicle interior heat exchanger 130 and the first vehicle interior heat exchanger 120 in sequence.

[0114] It can be understood that when the first vehicle heat exchanger 120 and the second vehicle heat exchanger 130 heat the vehicle at the same time, the air temperature heated by the first vehicle heat exchanger 120 is higher than the air temperature heated by the second vehicle heat exchanger 130, because the refrigerant first flows through the first vehicle heat exchanger 120 to release part of the heat and then flows to the second vehicle heat exchanger 130 to continue to release heat. By arranging the fan 600 on the side of the second vehicle heat exchanger 130 away from the first vehicle heat exchanger 120, the airflow flows through the second vehicle heat exchanger 130 and the first vehicle heat exchanger 120 in turn. In this way, the airflow heated by the second vehicle heat exchanger 130 can be heated by the first vehicle heat exchanger 120 again, and the temperature of the airflow can gradually increase, so that the heating effect is better and the user experience is better.
