[0115] In some embodiments, the liquid reservoir 21 is provided with a gas-liquid separation unit connected in series between the condenser 22 and the evaporator 23.

[0116] Optionally, the at least one heat exchanger further comprises a subcooler 24 connected in series between the condenser 22 and the evaporator 23, wherein the subcooler 24 is arranged between the condenser 22 and the liquid reservoir 21, or the subcooler 24 is arranged between the evaporator 23 and the liquid reservoir 21. The arrangement of the subcooler 24 can further increase the subcooling degree of the condensed saturated liquid and the cooling liquid, reduce the flash gas generated during throttling of the refrigerant, and thus help to increase the evaporation capacity of the evaporator 23 and improve the heat exchange efficiency.

[0117] As Figures 1 to 2 , the subcooler 24 is located between the liquid reservoir 21 and the condenser 22, at this time, the subcooler 24 is provided with a through hole for connecting the condensing outlet of the condenser 22 and the condensing inlet of the liquid reservoir 21, which serves as a channel connecting the condenser 22 and the liquid reservoir 21, ensuring that the refrigerant flowing out of the condenser 22 can pass through the subcooler 24 (without heat exchange), enter the liquid reservoir 21 and realize the separation of liquid refrigerant and gaseous refrigerant in the liquid reservoir 21, and the liquid reservoir 21 is also provided with a bottom corner hole for connecting the subcooling inlet of the subcooler 24, ensuring that the liquid refrigerant flows through the bottom corner hole, the subcooling inlet and enters the subcooler 24 for secondary heat exchange, and flows out of the subcooler 24 through the subcooling outlet on the subcooler 24, which is connected to the throttling inlet of the throttling device such as an expansion valve. Of course, in other embodiments, the subcooler 24 is located between the liquid reservoir 21 and the evaporator 23.

[0118] In some embodiments, the heat exchange and liquid storage assembly 20 further comprises a third valve 33, which is connected in series between the condenser 22 and the evaporator 23, and is configured to control the flow of the refrigerant from the condenser 22 to the evaporator 23. The third valve 33 is arranged at the inlet of the evaporator 23, which on one hand, controls the flow of the refrigerant into the evaporator 23, ensures that the refrigerant flowing out of the evaporator 23 is in gaseous state, reduces the content of liquid refrigerant, and thus reduces the possibility of liquid knock of the refrigerant into the compressor 10, avoids insufficient refrigeration caused by too small refrigerant flow, ensures the refrigeration capacity of the evaporator 23, and improves the heat exchange efficiency. On the other hand, the low-temperature and high-pressure liquid refrigerant can be throttled through the throttling hole of the third valve 33 to become low-temperature and low-pressure mist liquid refrigerant, which meets the evaporation condition of the liquid refrigerant, and thus improves the evaporation and heat absorption efficiency.

[0119] In order to further improve the integration degree of the heat exchange and liquid storage assembly 20, in an embodiment, the third valve 33 is integrated in the liquid storage tank 21. It can be understood that, in combination with Figures 1 to 4 , the liquid storage tank 21 is integrated with a throttling flow channel, which is arranged independently of the built-in flow channel of the liquid storage tank 21 and does not communicate with each other. The throttling flow channel is provided with a throttling inlet which is connected to the subcooling outlet of the subcooler 24, and a throttling outlet which is connected to the inlet of the evaporator 23. In this way, the pressure and flow of the refrigerant flowing from the condenser 22 to the evaporator 23 can be adjusted, and at the same time, the integration degree of the liquid storage tank 21 and the third valve 33 can be improved, the external pipeline can be reduced, and thus the integration degree of the heat exchange and liquid storage assembly 20 can be improved, and the space occupation of the heat exchange and liquid storage assembly 20 can be reduced.

[0120] The refrigerant flow path is configured to allow the refrigerant flowing into the third inlet to sequentially exchange heat with the condenser 22, the liquid storage tank 21, the subcooler 24, and the evaporator 23, and is further configured to allow the refrigerant after heat exchange to sequentially flow back to the third outlet through the liquid storage tank 21, the subcooler 24, and the condenser 22.

[0121] The heat exchanger can be a plate heat exchanger, which is configured to stack a plurality of plates, and the gap between adjacent two plates forms a first inter-plate flow channel and a second inter-plate flow channel which do not communicate with each other. The first inter-plate flow channel is configured as a refrigerant flow path for the refrigerant to flow, and is connected to the exhaust port 1204 of the compressor 10 through the corner hole on the plate. The second inter-plate flow channel is configured as a coolant flow path for the coolant to flow, and is connected to the corresponding functional system. The refrigerant and the coolant exchange heat through the plates.

[0122] Specifically, as Figure 1 and Figure 4For example, the first inlet and the first outlet on the condenser 22 are connected by a first cooling liquid flow path and are used to connect the corresponding functional system, and then the cooling liquid in the first cooling liquid flow path is heat-exchanged with the refrigerant in the refrigerant flow path of the condenser 22; the second inlet and the second outlet on the evaporator 23 are connected by a second cooling liquid flow path and are used to connect the corresponding functional system, and then the cooling liquid in the second cooling liquid flow path is heat-exchanged with the refrigerant in the refrigerant flow path of the evaporator 23.

[0123] In the ordinary refrigeration and heating process, because the heat exchange liquid storage assembly 20 is connected to the compressor 10 through the condenser 22, the third inlet of the condenser 22 is directly connected to the exhaust port 1204 of the compressor 10, so that the refrigerant directly enters the condenser 22 through the third inlet (exhaust port 1204), realizes liquefaction, releases heat to the cooling liquid, completes heat exchange, and in order to avoid refrigerant leakage, a first sealing ring 73 is arranged between the third inlet and the exhaust port 1204.

[0124] In order to ensure that the refrigerant that has completed heat absorption flows back to the compressor 10 to participate in the cycle again, the liquid storage tank 21 is provided with a through hole that communicates with the evaporator 23 and the condenser 22. The through hole is connected to the partial refrigerant flow path formed by the superimposed angle holes on the evaporator 23 and the partial refrigerant flow path formed by the superimposed angle holes on the condenser 22, so that the refrigerant that has completed heat absorption passes through the evaporator 23, the liquid storage tank 21, the subcooler 24, and the condenser 22 in sequence, and enters the compressor 10 through the suction port 1203, cooperates with the refrigerant flow path in the compressor 10, and completes a cycle.

[0125] In order to ensure the reliability of heat exchange in the heat exchange liquid storage assembly 20, in an embodiment, a first heat insulation pad is arranged outside the evaporator 23, specifically between the evaporator 23 and the liquid storage tank 21. When the refrigerant vaporizes in the evaporator 23, it can avoid absorbing heat in the liquid storage tank 21 to a certain extent. When the first heat insulation pad completely wraps the evaporator 23, it can avoid absorbing heat on the side of the evaporator 23 to a certain extent, such as heat in the liquid storage tank 21 and heat in the external environment, and can also reduce the heat dissipation of the refrigerant that has completed heat absorption, thereby reducing the influence on the rear-end cycle.

[0126] In an embodiment, a second heat insulation pad is arranged on the outer periphery of the heat exchange liquid storage assembly 20, which wraps the evaporator 23, the liquid storage tank 21, the subcooler 24, and the condenser 22, thereby improving the heat insulation effect of the heat exchange liquid storage assembly 20.

[0127] In addition, since the heat exchange liquid storage assembly 20 is connected with the compressor 10 through the condenser 22, the condenser 22 is directly connected with the refrigerant outlet of the compressor 10 and the suction port 1203 of the compressor 10, so that the refrigerant directly enters the compressor 10 through the refrigerant outlet (suction port 1203), and in order to avoid refrigerant leakage, a second sealing ring 73 is arranged between the refrigerant outlet and the suction port 1203.

[0128] Optionally, the upper portion of the liquid storage device 21 is provided with an oil detection pipe 66, the oil detection pipe 66 is in communication with the inlet of the third valve 33, and the state of the refrigerant can be detected by connecting the oil detection pipe 66 with an external test equipment. The oil in the liquid storage device 21 can be conveniently detected. Optionally, the liquid storage device 21 is provided with a third sensor 63, the third sensor 63 is configured to detect the outlet refrigerant temperature and / or pressure of the evaporator 23, further, the liquid storage device 21 is provided with a fourth sensor 64, the fourth sensor 64 is configured to detect the inlet refrigerant temperature and / or pressure of the third valve 33. Further, the liquid storage device 21 is provided with a fifth sensor 65, the fifth sensor 65 is configured to detect the outlet refrigerant temperature and / or pressure of the third valve 33.

[0129] In some embodiments, the water-cooled flow path includes a first flow path 201 and a second flow path 202, the first flow path 201 is arranged in the condenser 22, and the second flow path 202 is arranged in the evaporator 23.

[0133] The exhaust gas distribution member 12 is provided with a first valve 31, a second valve 32, a first sensor 61, a transparent window 122, and the like.

[0134] The liquid reservoir 21 is provided with a third sensor 63, a fourth sensor 64, a fifth sensor 65, a third valve 33, a first observation window 211, a second observation window 212, an oil detection pipe 66, and the like.

[0135] The heat management device 100 includes a refrigerant circuit and a coolant circuit, and the coolant circuit and the refrigerant circuit are each closed-loop circulated and heat-exchanged through a heat exchanger (including an evaporator 23, a condenser 22, and a subcooler 24), thereby realizing effective temperature control of the vehicle battery, the electric drive, and the passenger compartment. The condenser 22, the subcooler 24, the liquid reservoir 21 (integrating a desiccant and a filter screen inside), and the evaporator 23 are stacked in the axial direction of the compressor 10 in the direction away from the compressor 10.

[0136] The condenser 22, the subcooler 24, the liquid reservoir 21 (integrating a desiccant and a filter screen inside), and the evaporator 23 are integrated as a whole through welding or bolt fixing, and adjacent heat exchangers or the liquid reservoir 21 realize the flow of refrigerant through internal flow channels.

[0137] The compressor 10 and the heat exchange and liquid storage assembly 20 are connected as a whole through a sealing ring 73 and a bolt, the refrigerant flows and phase changes between the two to realize heating and cooling of the externally flowing coolant, and different sub-components of the compressor 10 are connected through the sealing ring 73 and the bolt. The coolant enters and exits through the inlet and outlet of the evaporator 23 and the condenser 22, realizing heat exchange between the coolant and the refrigerant.

[0138] A continuous refrigerant flow channel is formed on the side of the heat exchange and liquid storage assembly 20 through welding or bolt connection. The welded flow channel inlet is connected with the exhaust gas distribution member 12 through a sealing ring 73 and a bolt. A continuous refrigerant flow channel is formed on the side of the heat exchange and liquid storage assembly 20 through welding or bolt connection. The welded flow channel outlet is connected with the suction flow channel 1042 of the compressor 10 through a sealing ring 73 and a bolt.

[0139] In combination with the foregoing, the heat management device 100 of the utility model has a first working mode and a second working mode.

[0140] In the first working mode: the high pressure refrigerant compressed by compressor 10 flows out through the first valve 31 (fully open state) and the discharge distribution 12, then enters the condenser 22 through the sealing ring 73. The refrigerant releases heat to the cooling liquid (which can be antifreeze) in the condenser 22. The refrigerant flows out of the condenser 22, then enters the liquid receiver 21 through the internal hole of the subcooler 24, where the separation of liquid refrigerant and gaseous refrigerant is achieved. The liquid refrigerant flows into the subcooler 24 through the outlet of the liquid receiver 21. In the subcooler 24, the refrigerant and the cooling liquid achieve secondary heat exchange, further increasing the subcooling degree of the refrigerant. The refrigerant flows out of the subcooler 24 from the outlet of the subcooler 24, enters the third valve 33 integrated on the liquid receiver 21, and achieves the flow regulation and throttling process of the refrigerant in the third valve 33. The refrigerant flowing out of the third valve 33 enters the evaporator 23 through the refrigerant flow channel integrated on the liquid receiver 21. In the evaporator 23, the refrigerant expands and absorbs the heat of the cooling liquid. The refrigerant that has completed heat absorption flows out of the water-cooled evaporator 23 from the side and enters the refrigerant flow channel of the heat exchanger and the liquid receiver 21. The refrigerant enters the suction flow channel 1042 of the compressor 10 through the sealing ring 73, and finally the refrigerant is sucked into the low-pressure cavity of the compressor 10. The low-pressure refrigerant is pressurized by the high-pressure cavity of the compressor 10, then flows out of the discharge distribution 12 to complete a cycle. In this mode, the second valve 32 remains closed. The cooling liquid exchanges heat with the evaporator 23 and the condenser 22. If the cooling liquid in the evaporator 23 is connected to the heat exchanger in the passenger compartment, the refrigeration or defogging function is achieved. If the cooling liquid in the condenser 22 is connected to the heat exchanger in the passenger compartment, the heating or defrosting function is achieved.

[0141] In the second working mode, when the ordinary refrigerant cycle cannot meet the heating demand of the system, part of the refrigerant flows out of the discharge distribution 12 through the first valve 31 (partially open state), then flows into the condenser 22 through the sealing ring 73. The refrigerant entering the condenser 22 still flows through the condenser 22, the liquid receiver 21, the subcooler 24, the third valve 33, the evaporator 23, and finally is sucked into the compressor 10 through the suction flow channel 1042. At the same time, another part of the refrigerant also enters the suction flow channel 1042 of the compressor 10 through the first valve 31 (partially open state) and the second valve 32 (partially open state). The two streams of refrigerant are mixed in the suction flow channel 1042 of the compressor 10. After mixing, the refrigerant is pressurized by the compressor 10, then flows out of the discharge distribution 12 to complete the heating cycle. The return flow channels of the first valve 31 and the second valve 32 increase the total flow of the refrigerant flowing through the compressor 10, increase the output power of the compressor 10, and improve the heating capacity of the system. By adjusting the opening degree of the first valve 31, the exhaust pressure of the compressor 10 can be adjusted, and the effect of increasing the output power of the compressor 10 to achieve rapid heating can be achieved.
