DETAILED DESCRIPTION

[0063] The vehicle-mounted refrigerator 100 according to the first aspect of the present application is described below with reference to FIGS. 1-26.

[0064] As shown in FIGS. 1-26, the vehicle-mounted refrigerator 100 according to the first aspect of the present application includes an inner box body 5, an outer box body 6, a heat exchange module 2, and an auxiliary heat exchange module 3.

[0065] Specifically, the outer box body 6 is arranged at the outer periphery of the inner box body 5, and the outer box body 6 and the inner box body 5 together define a containing cavity 7. The heat exchange module 2 is arranged in the containing cavity 7. The auxiliary heat exchange module 3 is arranged in the containing cavity 7, and the auxiliary heat exchange module 3 is arranged at the heat exchange module 2, and the auxiliary heat exchange module 3 is used for heat exchange with the heat exchange module 2.

[0066] For example, in the example of FIGS. 1-6, the containing cavity 7 defined by the inner box body 5 and the outer box body 6 together provides installation space for the heat exchange module 2 and the auxiliary heat exchange module 3, so as to improve the integration of the vehicle-mounted refrigerator 100, increase the structural integrity of the vehicle-mounted refrigerator 100, and facilitate the improvement of the structural strength of the vehicle-mounted refrigerator 100, thereby prolonging the service life of the vehicle-mounted refrigerator 100. The containing cavity 7 is also provided with a heat preservation layer 1, and the heat preservation layer 1 is arranged in a staggered manner with the heat exchange module 2 and the auxiliary heat exchange module 3, so as to avoid interference of the heat preservation layer 1 with the heat exchange module 2 and the auxiliary heat exchange module 3, and at the same time increase the heat preservation performance of the vehicle-mounted refrigerator 100.

[0067] The auxiliary heat exchange module 3 is adjacent to the heat exchange module 2, so that the auxiliary heat exchange module 3 and the heat exchange module 2 exchange heat, thereby reducing or increasing the temperature in the inner box 5 through heat exchange between the heat exchange module 2 and the inner box 5, that is, the vehicle-mounted refrigerator 100 is in a refrigerator cooling mode or a refrigerator heating mode. Thus, it is beneficial to avoid the problems of insufficient heating or cooling capacity and low efficiency caused by poor heating or cooling of the heat exchange module 2, thereby improving the use stability of the vehicle-mounted refrigerator 100. In addition, the auxiliary heat exchange module 3 and the heat exchange module 2 exchange heat, which is beneficial to realize the gradual temperature change of the vehicle-mounted refrigerator 100, thereby improving the operation stability of the vehicle-mounted refrigerator 100.

[0068] In actual use, when the heat of the auxiliary heat exchange module 3 is higher than the heat of the heat exchange module 2, the auxiliary heat exchange module 3 exchanges heat to the heat exchange module 2 to meet the heating demand of the vehicle-mounted refrigerator 100; when the heat of the auxiliary heat exchange module 3 is lower than the heat of the heat exchange module 2, the heat exchange module 2 exchanges heat to the auxiliary heat exchange module 3 to meet the cooling demand of the vehicle-mounted refrigerator 100. That is, the vehicle-mounted refrigerator 100 meets the heating and cooling demands of the vehicle-mounted refrigerator 100 through heat exchange between the auxiliary heat exchange module 3 and the heat exchange module 2, thereby enriching the functionality of the vehicle-mounted refrigerator 100, improving the comfort of use of the user, and thereby increasing the market competitiveness of the vehicle-mounted refrigerator 100.

[0069] According to the vehicle-mounted refrigerator 100 of the embodiments of the present application, the auxiliary heat exchange module 3 and the heat exchange module 2 exchange heat, thereby meeting the heating and cooling demands of the vehicle-mounted refrigerator 100, thereby enriching the functionality of the vehicle-mounted refrigerator 100, improving the comfort of use of the user, and thereby increasing the market competitiveness of the vehicle-mounted refrigerator 100, and at the same time, the auxiliary heat exchange module 3 is beneficial to improve the efficiency of the heat exchange module 2 for heating and cooling the vehicle-mounted refrigerator 100.

[0070] According to some embodiments of the present application, with reference to FIGS. 1 and 2, the auxiliary heat exchange module 3 is arranged on the outer box 6. Thus, the installation stability of the auxiliary heat exchange module 3 is increased, the distance between the auxiliary heat exchange module 3 and the inner box 5 is increased, thereby further improving the temperature change stability of the vehicle-mounted refrigerator 100, avoiding the influence of fast temperature change on the food in the vehicle-mounted refrigerator 100, improving the usability of the vehicle-mounted refrigerator 100, and at the same time, being beneficial to prolong the service life of the vehicle-mounted refrigerator 100.

[0071] In addition, referring to FIG. 1, the heat exchange module 2 is arranged at one side of the accommodating cavity 7 adjacent to the inner box 5, and the auxiliary heat exchange module 3 is arranged at one side of the heat exchange module 2 away from the center of the inner box 5. In this way, the auxiliary heat exchange module 3 and the heat exchange module 2 are arranged in sequence in a direction away from the center of the inner box 5, thereby improving the heat exchange efficiency of the auxiliary heat exchange module 3 and the heat exchange module 2, reducing the distance between the heat exchange module 2 and the inner box 5, improving the efficiency of the heat exchange between the heat exchange module 2 and the inner box 5 to reduce or increase the temperature in the inner box 5, and increasing the distance between the auxiliary heat exchange module 3 and the inner box 5, thereby improving the temperature change stability of the vehicle-mounted refrigerator 100.

[0072] According to some embodiments of the present application, referring to FIG. 2, the heat exchange module 2 includes a first heat exchange end 22 and a second heat exchange end 23 arranged oppositely. The first heat exchange end 22 is adjacent to the inner box 5, and the second heat exchange end 23 is located between the first heat exchange end 22 and the auxiliary heat exchange module 3, and the auxiliary heat exchange module 3 is used for heat exchange with the second heat exchange end 23. That is, in a direction away from the center of the inner box 5, the first heat exchange end 22, the second heat exchange end 23, and the auxiliary heat exchange module 3 are arranged in sequence. The auxiliary heat exchange module 3 exchanges heat with the second heat exchange end 23, the first heat exchange end 22 exchanges heat with the inner box 5, and the second heat exchange end 23 exchanges heat with the first heat exchange end 22, thereby reducing or increasing the temperature in the inner box 5, that is, achieving refrigeration or heating of the vehicle-mounted refrigerator 100.

[0073] When one of the first heat exchange end 22 and the second heat exchange end 23 is a cold end, the other one of the first heat exchange end 22 and the second heat exchange end 23 is a hot end, so that the vehicle-mounted refrigerator 100 can be switched between a refrigerator heating mode and a refrigerator refrigeration mode. When the first heat exchange end 22 is a cold end, the second heat exchange end 23 is a hot end, the temperature of the auxiliary heat exchange module 3 is relatively low, the auxiliary heat exchange module 3 exchanges heat with the second heat exchange end 23 to reduce the temperature of the second heat exchange end 23, the first heat exchange end 22 exchanges heat with the inner box 5 to increase the temperature, the temperature of the second heat exchange end 23 is lower than that of the first heat exchange end 22, the heat exchange module 2 operates to transfer the heat of the first heat exchange end 22 to the second heat exchange end 23, thereby making the vehicle-mounted refrigerator 100 in the refrigerator refrigeration mode. When the first heat exchange end 22 is a hot end, the second heat exchange end 23 is a cold end, the temperature of the auxiliary heat exchange module 3 is relatively high, the auxiliary heat exchange module 3 exchanges heat with the second heat exchange end 23 to increase the temperature of the second heat exchange end 23, the heat exchange module 2 operates to transfer the heat of the second heat exchange end 23 to the first heat exchange end 22, and the first heat exchange end 22 exchanges heat with the inner box 5, thereby making the vehicle-mounted refrigerator 100 in the refrigerator heating mode.

[0074] Optionally, when the vehicle-mounted refrigerator 100 is in the refrigerator cooling mode, the vehicle-mounted refrigerator 100 circulates the air by the air circulation module to force convection heat exchange, the air circulation module absorbs and removes the heat in the vehicle-mounted refrigerator 100, which is conducive to completing the entire refrigeration cycle. Thus, the vehicle-mounted refrigerator 100 can meet the functional requirements of refrigeration or freezing, and can also avoid dissipating the heat in the vehicle-mounted refrigerator 100 into the vehicle.

[0075] Optionally, the heat exchange module 2 includes a semiconductor refrigeration sheet or a refrigerator heat exchanger. The semiconductor refrigeration sheet is a refrigeration device that generates negative thermal resistance and has no moving parts, and has high reliability. The semiconductor refrigeration sheet can switch the cold end and the hot end. When the first heat exchange end 22 is the hot end and is in contact with the inner box 5 to release heat, the auxiliary heat exchange module 3 is not started in the case where there is no heat of the motor and the like available. The semiconductor refrigeration sheet can use its own heat to heat the inside of the inner box 5. When there is heat of the motor and the like available, the auxiliary heat exchange module 3 can be started, the second heat exchange end 23 of the semiconductor refrigeration sheet is in contact with the auxiliary heat exchange module 3 to absorb heat, and then the heat is transferred to the first heat exchange end 22 to exchange heat with the inner box 5, so that the heat of the semiconductor refrigeration sheet itself and the heat of the motor and the like are used to heat the inside of the inner box 5, and the vehicle-mounted refrigerator 100 is in the refrigerator heating mode. When the vehicle-mounted refrigerator 100 is in the refrigerator cooling mode, the first heat exchange end 22 is the cold end, and the semiconductor refrigeration sheet can use its own refrigeration to exchange heat with the inner box 5.

[0076] The condenser and the evaporator in the refrigerator heat exchanger are used for heat exchange, so that the refrigerator heat exchanger can realize refrigeration and heating of the vehicle-mounted refrigerator 100. Thus, the vehicle-mounted refrigerator 100 can meet the user's demand for freezing or refrigeration of food, and can also meet the heating demand of passengers in the vehicle for food and beverages in cold weather, thereby improving the user's experience and the market competitiveness of the vehicle-mounted refrigerator 100.

[0077] According to some embodiments of the present application, the auxiliary heat exchange module 3 includes a liquid cooling fin. The liquid cooling fin has the advantages of stable temperature rise and temperature drop. Using the liquid cooling fin as the auxiliary heat exchange module 3 makes the heat exchange between the auxiliary heat exchange module 3 and the heat exchange module 2 more stable, thereby improving the temperature change stability of the vehicle-mounted refrigerator 100, prolonging the service life of the vehicle-mounted refrigerator 100, and improving the user experience of the vehicle-mounted refrigerator 100.

[0078] Referring to FIGS. 3-26, the thermal management system 200 according to the second aspect of the present application includes the motor heat exchange circuit 10 and the vehicle-mounted refrigerator 100. The vehicle-mounted refrigerator 100 is the vehicle-mounted refrigerator 100 according to the first aspect of the present application described above, and the auxiliary heat exchange module 3 of the vehicle-mounted refrigerator 100 is connected to the motor heat exchange circuit 10.

[0079] According to the heat management system 200 provided in the embodiment of the present application, by using the vehicle-mounted refrigerator 100, heat exchange between the auxiliary heat exchange module 3 and the motor heat exchange circuit 10 is facilitated, so that the heat in the motor heat exchange circuit 10 is effectively utilized to reduce energy consumption and improve the heat exchange efficiency of the heat management system 200.

[0080] Further, the heat management system 200 further comprises the motor first heat exchanger 101 and the heat exchange device 105. The motor first heat exchanger 101 and the heat exchange device 105 are connected to form the motor heat exchange circuit 10. Thus, the auxiliary heat exchange module 3 exchanges heat with the motor first heat exchanger 101 and the heat exchange device 105 in the motor heat exchange circuit 10. The motor first heat exchanger 101 can be integrated on the motor to realize temperature rise and heat dissipation of the motor and improve the stability of the motor operation. The motor first heat exchanger 101 can be located between the auxiliary heat exchange module 3 and the heat exchange device 105.

[0081] Still further, the heat exchange device 105 comprises the plate heat exchanger 102 and the motor second heat exchanger 103, and at least one of the plate heat exchanger 102 and the motor second heat exchanger 103 is connected with the motor first heat exchanger 101 to form the motor heat exchange circuit 10. Thus, the selection of heat exchange with the auxiliary heat exchange module 3 in the motor heat exchange circuit 10 is enriched, so as to improve the temperature change efficiency of the auxiliary heat exchange module 3 and improve the refrigeration and heating efficiency of the vehicle-mounted refrigerator 100. The plate heat exchanger 102 can be arranged between the motor second heat exchanger 103 and the motor first heat exchanger 101.

[0082] Further, referring to FIGS. 3-26, the motor heat exchange circuit 10 is provided with a four-way valve 104. The four-way valve 104 comprises a first interface 1041, a second interface 1042, a third interface 1043 and a fourth interface 1044. The first interface 1041 is connected with a first end of a first heat exchange channel 1021 of the plate heat exchanger 102, the second interface 1042 and a second end of the first heat exchange channel 1021 are both connected with one end of the motor first heat exchanger 101, the third interface 1043 is connected with one end of the motor second heat exchanger 103, the other end of the motor second heat exchanger 103 is connected with one end of the auxiliary heat exchange module 3, the other end of the auxiliary heat exchange module 3 is connected with the other end of the motor first heat exchanger 101, and the fourth interface 1044 is connected with the other end of the motor second heat exchanger 103.

[0083] Therefore, the first heat exchange end 22 of the first heat exchange channel 1021 of the plate heat exchanger 102, the second heat exchange end 23 of the first heat exchange channel 1021, one end of the motor first heat exchanger 101, and the other end of the motor second heat exchanger 103 are connected in an on-off manner, so that the heat management system 200 can select different flow paths through the four-way valve 104, increase the diversity of the selection mode of the heat management system 200, and further improve the user experience.

[0084] Further, referring to FIGS. 3-6, the four-way valve 104 includes a first working mode, a second working mode, a third working mode, and a fourth working mode.

[0085] As shown in FIG. 3, when the four-way valve 104 is in the first working mode, the second interface 1042 and the third interface 1043 are connected, and the motor second heat exchanger 103 and the motor first heat exchanger 101 are connected to form the motor heat exchange circuit 10. That is, the first interface 1041 and the fourth interface 1044 are closed, so that only the motor first heat exchanger 101 and the motor second heat exchanger 103 in the motor heat exchange circuit 10 are connected to the auxiliary heat exchange module 3. In use, after the refrigerant is cooled in the motor second heat exchanger 103, the low-temperature refrigerant absorbs heat from the auxiliary heat exchange module 3 and the motor first heat exchanger 101 to increase the temperature of the auxiliary heat exchange module 3 and the motor, and the auxiliary heat exchange module 3 exchanges heat with the heat exchange module 2 to reduce the temperature in the vehicle refrigerator 100, so that the vehicle refrigerator 100 is in a refrigerator cooling mode, and the use stability of the motor is increased. Therefore, the first working mode is suitable for a high-temperature heat dissipation circuit, so that the vehicle refrigerator 100 is in a refrigerator cooling mode and the motor is in a motor heat dissipation state.

[0086] As shown in FIG. 4, when the four-way valve 104 is in the second working mode, the first interface 1041 and the third interface 1043 are connected, and the motor second heat exchanger 103, the plate heat exchanger 102, and the motor first heat exchanger 101 are connected to form the motor heat exchange circuit 10. That is, the second interface 1042 and the fourth interface 1044 are closed, so that the plate heat exchanger 102, the motor second heat exchanger 103, and the motor first heat exchanger 101 in the motor heat exchange circuit 10 are connected to the auxiliary heat exchange module 3. In use, after the refrigerant absorbs heat in the auxiliary heat exchange module 3 and / or the motor first heat exchanger 101, part of the refrigerant enters the plate heat exchanger 102 to provide part of the heat to the entire heat management system 200, and part of the refrigerant enters the motor second heat exchanger 103 to release part of the heat to the external environment through the motor second heat exchanger 103. Therefore, the second working mode is suitable for a case where the temperature of the heat management system 200 is between -10℃ and 10℃, the vehicle refrigerator 100 is in a refrigerator cooling mode, and the motor is in a motor heat dissipation state.

[0087] As shown in FIG. 5, when the four-way valve 104 is in the third working mode, the first interface 1041 and the fourth interface 1044 are open, and the plate heat exchanger 102 and the motor first heat exchanger 101 are connected to form the motor heat exchange circuit 10. That is, the second interface 1042 and the third interface 1043 are closed, so that only the plate heat exchanger 102 and the motor first heat exchanger 101 in the motor heat exchange circuit 10 are connected to the auxiliary heat exchange module 3. In use, after the refrigerant absorbs the heat of the motor first heat exchanger 101, the temperature of the refrigerant is increased, part of the refrigerant enters the plate heat exchanger 102 to provide part of the heat to the entire thermal management system 200, and part of the refrigerant enters the auxiliary heat exchange module 3 to assist the vehicle-mounted refrigerator 100 to heat, so as to fully utilize the heat of the motor and the plate heat exchanger 102, thereby improving the heating efficiency of the vehicle-mounted refrigerator 100. Therefore, the third working mode is suitable for the temperature of the thermal management system 200 being below -10°C, the vehicle-mounted refrigerator 100 being in the refrigerator heating mode, and the motor being in the motor heat dissipation state.

[0088] As shown in FIG. 6, when the four-way valve 104 is in the fourth working mode, the first interface 1041 is connected to the third interface 1043 and the fourth interface 1044, and the motor second heat exchanger 103, the plate heat exchanger 102 and the motor first heat exchanger 101 are connected to form the motor heat exchange circuit 10. That is, only the second interface 1042 is closed, so that the motor second heat exchanger 103, the plate heat exchanger 102 and the motor first heat exchanger 101 in the motor heat exchange circuit 10 are connected to the auxiliary heat exchange module 3. In use, after the refrigerant absorbs heat in the auxiliary heat exchange module 3 and / or the motor first heat exchanger 101, part of the refrigerant enters the plate heat exchanger 102 to provide part of the heat to the entire thermal management system 200, and part of the refrigerant enters the motor second heat exchanger 103 to release part of the heat to the external environment through the motor second heat exchanger 103. Therefore, the fourth working mode is suitable for the high-temperature heat dissipation circuit, and the combination of the vehicle-mounted refrigerator 100 being in the refrigerator cooling mode and the motor being in the motor heat dissipation state.

[0089] According to some embodiments of the present application, referring to FIGS. 7-26, the thermal management system 200 further comprises an air conditioner module 20, a first on-off valve 30, a first throttling valve 70 and a fourth on-off valve 60. The air conditioner module 20 comprises a compressor 201, a first vehicle interior heat exchanger 202 and a vehicle exterior heat exchanger 203 connected to form a first refrigerant circuit. The air conditioner module 20 can perform refrigeration or heating on the air conditioner side in the vehicle. The compressor 201 inhales low-temperature and low-pressure refrigerant from an inlet, and after the refrigerant is compressed by the operation of the compressor 201, high-temperature and high-pressure refrigerant is discharged from an outlet.

[0090] The first in-vehicle heat exchanger 202 can condense and cool the high-temperature and high-pressure refrigerant discharged by the compressor 201 (the heat released by the refrigerant in the first in-vehicle heat exchanger 202 is taken away by the air outside the first in-vehicle heat exchanger 202), and the air outside the first in-vehicle heat exchanger 202 is heated. When the first in-vehicle heat exchanger 202 is not working, it can only serve as a flow path for the refrigerant. The external heat exchanger 203 can function as a condenser or an evaporator according to the cooling or heating needs of the thermal management system 200.

[0091] The plate heat exchanger 102 is connected in parallel with the external heat exchanger 203, the third end of the second heat exchange channel 1022 of the plate heat exchanger 102 is connected to the first end of the first in-vehicle heat exchanger 202, and the fourth end of the second heat exchange channel 1022 is connected to the inlet of the compressor 201. Thus, it is beneficial for the combined operation of the air conditioning module 20 and the vehicle-mounted refrigerator 100 to enrich the use selectivity of the thermal management system 200.

[0092] The first on-off valve 30 is connected between the first end of the external heat exchanger 203 and the first in-vehicle heat exchanger 202, and the first end of the external heat exchanger 203 is connected to the third end of the second heat exchange channel 1022. The first throttle valve 70 is connected in parallel with the first on-off valve 30. The fourth on-off valve 60 is connected between the second end of the external heat exchanger 203 and the inlet of the compressor 201, and the second end of the external heat exchanger 203 is connected to the fourth end of the second heat exchange channel 1022.

[0093] The first on-off valve 30 can open or close the end of the external heat exchanger 203 connected to the third end of the second heat exchange channel 1022 and the first in-vehicle heat exchanger 202. The fourth on-off valve 60 can open or close the end of the external heat exchanger 203 connected to the fourth end of the second heat exchange channel 1022 and the compressor 201. The first throttle valve 70 can throttle and cool the high-temperature and high-pressure refrigerant from the compressor 201. Thus, by selectively opening and closing the first on-off valve 30, the first throttle valve 70 and the fourth on-off valve 60, it is beneficial to enrich the selectivity of the thermal management system 200.

[0094] Referring to FIGS. 9 and 18, when the air conditioning module 20 is in a heating mode, the vehicle-mounted refrigerator 100 is in a refrigerator heating mode, wherein the four-way valve 104 is in the second working mode, the fourth on-off valve 60 is open, the first on-off valve 30 is closed, the first throttle valve 70 is open to throttle, and the first in-vehicle heat exchanger 202 functions as a condenser.

[0095] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, it flows to the first vehicle interior heat exchanger 202 (with air passing through), and low-temperature air is heated to high-temperature air by the first vehicle interior heat exchanger 202 to provide heating to the vehicle interior. The refrigerant is cooled to medium-temperature and high-pressure refrigerant by the first vehicle interior heat exchanger 202 and flows to the motor heat exchange circuit 10. The motor waste heat is all used as the heat absorption heat source of the plate heat exchanger 102. When the heat still cannot meet the use demand of the plate heat exchanger 102, the motor is blocked to increase the heat generation power of the motor to meet the heat demand of the motor heat exchange circuit 10. The refrigerant exchanges heat with the auxiliary heat exchange module 3 to complete the heating of the vehicle-mounted refrigerator 100. The refrigerant is connected to the gas-liquid separator through the fourth on-off valve 60, and the gas-liquid separator separates the refrigerant and the refrigeration oil. At the same time, the gas-liquid separator acts as an intermediate storage of the refrigerant (gas) to ensure the stable suction of the compressor 201, and finally the refrigerant returns to the compressor 201, thereby forming a cycle.

[0096] Referring to FIGS. 10 and 20, when the air conditioning module 20 is in the heating mode, the vehicle-mounted refrigerator 100 is in the refrigerator heating mode, and the four-way valve 104 is in the third working mode.

The refrigerant is cooled to medium-temperature and high-pressure refrigerant by the first vehicle interior heat exchanger 202 and flows to the motor heat exchange circuit 10. The motor waste heat is all used as the heat absorption heat source of the plate heat exchanger 102. When the heat still cannot meet the use demand of the plate heat exchanger 102, the motor is blocked to increase the heat generation power of the motor to meet the heat demand of the motor heat exchange circuit 10. The refrigerant exchanges heat with the auxiliary heat exchange module 3 to complete the heating of the vehicle-mounted refrigerator 100. The refrigerant is connected to the gas-liquid separator through the fourth on-off valve 60, and the gas-liquid separator separates the refrigerant and the refrigeration oil. At the same time, the gas-liquid separator acts as an intermediate storage of the refrigerant (gas) to ensure the stable suction of the compressor 201, and finally the refrigerant returns to the compressor 201, thereby forming a cycle.

[0098] Referring to FIGS. 11 and 19, when the air conditioning module 20 is in the heating mode, the vehicle-mounted refrigerator 100 is in the refrigerator heating mode, and the four-way valve 104 is in the fourth working mode (the heat dissipation of the motor and the heat absorption of the plate heat exchanger 102 are unbalanced, and the heat dissipation of the motor and the heat absorption of the plate heat exchanger 102 need to be precisely adjusted). At this time, the fourth on-off valve 60 is opened, the first on-off valve 30 is closed, the first throttling valve 70 is opened to throttle, and the first vehicle interior heat exchanger 202 acts as a condenser.

[0099] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, it flows to the first indoor heat exchanger 202 (with air passing through), and low-temperature air is heated to high-temperature air by the first indoor heat exchanger 202 to provide heating to the vehicle interior. The refrigerant is cooled to medium-temperature and high-pressure refrigerant by the first indoor heat exchanger 202 and flows to the motor heat exchange circuit 10, and part of the heat of the motor is used for waste heat recovery, and another part of the heat of the motor is released to the environment through the motor second heat exchanger 103. After the refrigerant exchanges heat with the auxiliary heat exchange module 3, heating of the vehicle refrigerator 100 is completed. The refrigerant is connected to the gas-liquid separator through the fourth on-off valve 60, and the gas-liquid separator separates the refrigerant and the refrigeration oil, and at the same time, the gas-liquid separator acts as an intermediate storage for the refrigerant (gas), ensuring stable suction of the compressor 201, and finally the refrigerant returns to the compressor 201, thereby forming a cycle.

[0100] Further, with reference to FIGS. 7-26, the air conditioning module 20 further comprises a second indoor heat exchanger 204, a second on-off valve 40, and a second throttling valve 80. One end of the second indoor heat exchanger 204 is connected to the second end of the outdoor heat exchanger 203 and the fourth end of the second heat exchange channel 1022, and the other end of the second indoor heat exchanger 204 is connected to the inlet of the compressor 201. The second on-off valve 40 connects the first end of the first indoor heat exchanger 202 and the outdoor heat exchanger 203. One end of the second throttling valve 80 is connected to the outdoor heat exchanger 203 and the fourth end of the second heat exchange channel 1022, and the other end of the second throttling valve 80 is connected to one end of the second indoor heat exchanger 204.

[0101] The second indoor heat exchanger 204 and the fourth on-off valve 60 can be used to connect the outdoor heat exchanger 203 and the fourth end of the second heat exchange channel 1022 to the inlet of the compressor 201, enriching the selectivity of the thermal management system 200. The second indoor heat exchanger 204 is suitable for functioning as an evaporator to cool high-temperature air to low-temperature air for refrigeration in the vehicle interior, and at this time, the refrigerant at the other end of the second indoor heat exchanger 204 is in a low-temperature and low-pressure state. The second on-off valve 40 can connect or disconnect the first indoor heat exchanger 202 and the outdoor heat exchanger 203. The second throttling valve 80 can throttle and cool the passing refrigerant to change the refrigerant into low-temperature and low-pressure wet steam or supercooled liquid.

[0102] With reference to FIGS. 8 and 15, when the air conditioning module 20 is in a refrigeration mode, the vehicle refrigerator 100 can be additionally in a refrigerator heating mode, wherein the four-way valve 104 is in a first working mode, the first on-off valve 30 and the second on-off valve 40 are connected, the fourth on-off valve 60 and the first throttling valve 70 are closed, and at the same time, the second throttling valve 80 is opened to throttle and cool.

[0103] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, the compressor 201 is connected to the first indoor heat exchanger 202 (no air circulation), and the first indoor heat exchanger 202 only serves as a flow channel. At this time, the other end of the first indoor heat exchanger 202 is still high-temperature and high-pressure refrigerant (gas). The other end of the first indoor heat exchanger 202 is connected to the outdoor heat exchanger 203 through the second on-off valve 40, and the refrigerant exchanges heat with the environment through the outdoor heat exchanger 203, so that the outlet of the outdoor heat exchanger 203 is medium-temperature and high-pressure refrigerant (which can be liquid or gas, determined by the environment temperature).

[0104] The outdoor heat exchanger 203 is connected to the second throttling valve 80, and the refrigerant is throttled and cooled to low-temperature and low-pressure wet steam or supercooled liquid through the second throttling valve 80. The outlet of the second throttling valve 80 is connected to the second indoor heat exchanger 204, and at this time, high-temperature air passes through the second indoor heat exchanger 204, and the second indoor heat exchanger 204 functions as an evaporator. The high-temperature air is cooled to low-temperature air to provide cooling for the vehicle interior, and the refrigerant at the other end of the second indoor heat exchanger 204 is low-temperature and low-pressure refrigerant.

[0105] The other end of the second indoor heat exchanger 204 is connected to a gas-liquid separator, which separates the refrigerant and the refrigeration oil, and at the same time, the gas-liquid separator serves as an intermediate storage for the refrigerant (gas) to ensure stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thereby forming a cycle.

[0106] At the same time, in the first working mode of the four-way valve 104, the refrigerant is cooled after being cooled in the motor second heat exchanger 103, and then enters the auxiliary heat exchange module 3 and / or the motor first heat exchanger 101 to absorb heat and carry away heat, thereby realizing the refrigeration of the vehicle-mounted refrigerator 100.

[0107] Referring to FIGS. 12 and 23, when the air conditioner is in a dehumidification mode, the first on-off valve 30 and the second on-off valve 40 are opened, the fourth on-off valve 60 and the first throttling valve 70 are closed, and the second throttling valve 80 is opened to function as a throttling valve.

[0108] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, the compressor 201 is connected to the first indoor heat exchanger 202 (whether to open the air circulation is determined according to the need), and the first indoor heat exchanger 202 is cooled according to the need. At this time, the other end of the first indoor heat exchanger 202 is still high-temperature and high-pressure refrigerant (gas). The other end of the first indoor heat exchanger 202 is connected to the outdoor heat exchanger 203 through the second on-off valve 40, and the refrigerant exchanges heat with the environment through the outdoor heat exchanger 203, so that the outlet of the outdoor heat exchanger 203 is medium-temperature and high-pressure refrigerant (which can be liquid or gas, determined by the environment temperature).

[0109] The vehicle-out heat exchanger 203 is connected to the second throttling valve 80, and the refrigerant is throttled and cooled by the second throttling valve 80 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the second throttling valve 80 is connected to the second vehicle-in heat exchanger 204, and at this time, high-temperature air passes through the second vehicle-in heat exchanger 204, and the second vehicle-in heat exchanger 204 functions as an evaporator, and the high-humidity air is cooled to condense water, so that the absolute humidity in the vehicle is reduced. If temperature compensation is required after the vehicle-in air passing through the second vehicle-in heat exchanger 204 is dehumidified, part of the vehicle-in air flows through the first vehicle-in heat exchanger 202 to be heated, so as to realize the control of the temperature in the vehicle while reducing the humidity in the vehicle.

[0110] The refrigerant at the other end of the second vehicle-in heat exchanger 204 is low-temperature and low-pressure refrigerant, and the other end of the second vehicle-in heat exchanger 204 is connected to a gas-liquid separator, which separates the refrigerant and the refrigeration oil, and at the same time, the gas-liquid separator functions as an intermediate storage of the refrigerant (gas), which ensures the stable suction of the compressor 201, and finally the refrigerant returns to the compressor 201, thereby forming a cycle.

[0111] Further, with reference to FIGS. 7-26, the outlet of the compressor 201 is connected to one end of the first vehicle-in heat exchanger 202, and the other end of the first vehicle-in heat exchanger 202 is selectively connected to at least one of the vehicle-out heat exchanger 203 and the plate heat exchanger 102. That is, the other end of the first vehicle-in heat exchanger 202 can be connected only to the vehicle-out heat exchanger 203, so that the refrigerant flowing out of the first vehicle-in heat exchanger 202 can flow only to the vehicle-out heat exchanger 203; or the other end of the first vehicle-in heat exchanger 202 is connected only to the plate heat exchanger 102, so that the refrigerant flowing out of the first vehicle-in heat exchanger 202 can flow only to the plate heat exchanger 102; or the other end of the first vehicle-in heat exchanger 202 is connected to both the vehicle-out heat exchanger 203 and the plate heat exchanger 102, so that the refrigerant flowing out of the first vehicle-in heat exchanger 202 can flow to both the vehicle-out heat exchanger 203 and the plate heat exchanger 102. In this way, the selectivity of the refrigerant flow is increased, and the thermal management system 200 is suitable for various use requirements of users.

[0112] At least one of the outdoor heat exchanger 203 and the plate heat exchanger 102 is selectively connected to at least one of one end of the second indoor heat exchanger 204 and the inlet of the compressor 201, and the other end of the second indoor heat exchanger 204 is connected to the inlet of the compressor 201. Thus, the refrigerant flowing out of the outdoor heat exchanger 203 and / or the plate heat exchanger 102 can pass through the second indoor heat exchanger 204 to return to the compressor 201, or the refrigerant flowing out of the outdoor heat exchanger 203 and / or the plate heat exchanger 102 can directly return to the compressor 201. Thus, during use, the thermal management system 200 can selectively connect the outdoor heat exchanger 203 and / or the plate heat exchanger 102 to the second indoor heat exchanger 204 and / or the inlet of the compressor 201 according to the current use of the vehicle, so that the thermal management system 200 is suitable for the current use of the vehicle.

[0113] According to some embodiments of the present application, referring to FIGS. 14-26, the thermal management system 200 further comprises a battery pack heat exchanger 90 and a fourth throttling valve 220. The battery pack heat exchanger 90 is connected in the first refrigerant circuit to be suitable for heat exchange with the battery pack, and the battery pack heat exchanger 90 is connected in parallel with the first indoor heat exchanger 202, and the battery pack heat exchanger 90 is selectively connected to one of the inlet and the outlet of the compressor 201. The fourth throttling valve 220 is connected between one end of the battery pack heat exchanger 90 and the inlet and the outlet of the compressor 201. That is, the refrigerant (gas) flowing out of the compressor 201 can flow to the first indoor heat exchanger 202 or to the battery pack heat exchanger 90. The fourth throttling valve 220 is arranged between the inlet and the outlet of the compressor 201 and the battery pack heat exchanger 90, and the flow of the refrigerant is accurately adjusted by electronic control to achieve efficient control of the temperature.

[0114] Optionally, the fourth throttling valve 220 can be a large-diameter electronic expansion valve. The large-diameter electronic expansion valve has faster response speed, adjustment accuracy and wider operating range, and is suitable for fine temperature control.

[0115] Further, referring to FIGS. 14-26, the thermal management system 200 further comprises a fifth on-off valve 230 and a sixth on-off valve 240. The fifth on-off valve 230 is connected between the outlet of the compressor 201 and the fourth throttling valve 220. The sixth on-off valve 240 is connected between the inlet of the compressor 201 and the fourth throttling valve 220. Thus, the fifth on-off valve 230 can open or close the flow path between the outlet of the compressor 201 and the battery pack heat exchanger 90, and the sixth on-off valve 240 can open or close the flow path between the inlet of the compressor 201 and the battery pack heat exchanger 90.

[0116] Referring to Fig. 15, when the air conditioning module 20 is in a refrigeration mode (compound increase motor heat exchange circuit 10 heat dissipation and / or refrigerator refrigeration mode), wherein the four-way valve 104 is in the first mode of operation, the fourth on-off valve 60 and the first throttle valve 70 are closed, the first on-off valve 30 and the second on-off valve 40 are opened, and the second throttle valve 80 is opened to function as a throttling cooling.

[0117] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, the compressor 201 is connected to the first vehicle interior heat exchanger 202 (without air passing through), and the first vehicle interior heat exchanger 202 only serves as a flow channel. At this time, the other end of the first vehicle interior heat exchanger 202 is still high-temperature and high-pressure refrigerant (gas).

[0118] The other end of the first vehicle interior heat exchanger 202 is connected to the vehicle exterior heat exchanger 203 through the second on-off valve 40, and the refrigerant exchanges heat with the environment through the vehicle exterior heat exchanger 203. The refrigerant is cooled by heat dissipation, and the outlet of the vehicle exterior heat exchanger 203 is medium-temperature and high-pressure refrigerant (which can be liquid or gas, determined by the environment temperature).

[0119] The vehicle exterior heat exchanger 203 is connected to the second throttle valve 80, and the refrigerant is throttled and cooled by the second throttle valve 80 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the second throttle valve 80 is connected to the second vehicle interior heat exchanger 204, and at this time, high-temperature air passes through the second vehicle interior heat exchanger 204, which functions as an evaporator. The high-temperature air is cooled to low-temperature air to provide cooling to the vehicle interior, and the other end of the second vehicle interior heat exchanger 204 is low-temperature and low-pressure refrigerant.

[0120] The other end of the second vehicle interior heat exchanger 204 is connected to the gas-liquid separator, which separates the refrigerant and the refrigeration oil. At the same time, the gas-liquid separator acts as an intermediate storage for the refrigerant (gas), ensuring stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thus forming a cycle.

[0121] When the four-way valve 104 is in the first mode of operation, the vehicle-mounted refrigerator 100 operates independently. The refrigerant is cooled after being cooled in the motor second heat exchanger 103, and then enters the auxiliary heat exchange module 3 and / or the motor first heat exchanger 101 to absorb heat and carry away heat, thereby achieving refrigeration for the vehicle-mounted refrigerator 100.

[0122] In addition, referring to FIGS. 7-26, the thermal management system 200 further comprises a third on-off valve 50, one end of the third on-off valve 50 being connected to the third end of the second heat exchange channel 1022, and the other end of the third on-off valve 50 being connected to the battery pack heat exchanger 90, the first end of the first in-vehicle heat exchanger 202, and the second end of the out-of-vehicle heat exchanger 203. Thus, the third on-off valve 50 is adapted to open or close the third end of the second heat exchange channel 1022 to the battery pack heat exchanger 90, the first in-vehicle heat exchanger 202, and the out-of-vehicle heat exchanger 203. By controlling the third on-off valve 50, it is beneficial to independently operate the on-board refrigerator 100, or to combine the on-board refrigerator 100 with the air conditioning module 20 and / or the battery pack heat exchanger 90.

[0123] Further, referring to FIGS. 14-26, the thermal management system 200 further comprises a third throttling valve 210, a first one-way valve 250, and a second one-way valve 260. The third throttling valve 210 is connected between the third end of the second heat exchange channel 1022 and the battery pack heat exchanger 90. The first one-way valve 250 is connected between the third on-off valve 50 and the third throttling valve 210, and the first one-way valve 250 only allows the refrigerant flowing out of the battery pack heat exchanger 90 to pass through. The second one-way valve 260 is connected between the end of the out-of-vehicle heat exchanger 203 away from the second on-off valve 40 and the third throttling valve 210, and the second one-way valve 260 only allows the refrigerant to flow to the battery pack heat exchanger 90.

[0124] The third throttling valve 210 can throttle and cool the refrigerant. The first one-way valve 250 can open or close the flow path between the third on-off valve 50 and the third throttling valve 210, and the sixth on-off valve 240 can open or close the flow path between the other end of the out-of-vehicle heat exchanger 203 and the third throttling valve 210. The first one-way valve 250 and the second one-way valve 260 only allow the refrigerant to flow in a specific direction, while preventing the refrigerant from flowing in the opposite direction, thereby ensuring that the flow direction of the refrigerant is suitable for the use mode of the battery pack heat exchanger 90 (see FIGS. 17, 21, and 22).

[0125] Referring to FIG. 16, when the air conditioning module 20 is in a refrigeration mode, the battery pack heat exchanger 90 is in a battery pack cooling mode, and the four-way valve 104 is in a first working mode, the fourth on-off valve 60, the fifth on-off valve 230, and the first throttling valve 70 are closed, the first on-off valve 30, the second on-off valve 40, and the sixth on-off valve 240 are opened, and the second throttling valve 80, the third throttling valve 210, and the fourth throttling valve 220 are opened for throttling.

[0126] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, the compressor 201 is connected to the first in-vehicle heat exchanger 202 (without air passing through), and the first in-vehicle heat exchanger 202 only serves as a flow channel. At this time, the other end of the first in-vehicle heat exchanger 202 is still high-temperature and high-pressure refrigerant (gas).

[0127] The other end of the first in-car heat exchanger 202 is connected to the out-car heat exchanger 203 through the second on-off valve 40, and the refrigerant exchanges heat with the environment through the out-car heat exchanger 203, and the refrigerant is cooled by heat release, and the outlet of the out-car heat exchanger 203 is a medium-temperature high-pressure refrigerant (which can be a liquid or a gas, determined by the ambient temperature).

[0128] After passing through the out-car heat exchanger 203, the refrigerant forms two branches:

[0129] Branch one: the out-car heat exchanger 203 is connected to the second throttling valve 80, and the refrigerant is throttled and cooled by the second throttling valve 80 to become a low-temperature low-pressure wet vapor or supercooled liquid; the outlet of the second throttling valve 80 is connected to the second in-car heat exchanger 204, at this time, high-temperature air passes through the second in-car heat exchanger 204, and the second in-car heat exchanger 204 functions as an evaporator, and the high-temperature air is cooled to low-temperature air to provide cooling for the car, and the refrigerant at the other end of the second in-car heat exchanger 204 is a low-temperature low-pressure refrigerant.

[0130] Branch two: the refrigerant is throttled and cooled by the third throttling valve 210 to become a low-temperature low-pressure wet vapor or supercooled liquid; the outlet of the third throttling valve 210 is connected to the battery pack heat exchanger 90, at this time, the battery pack heat exchanger 90 functions as an evaporator, and the high-temperature refrigerant is cooled to low-temperature refrigerant to provide cooling for the battery pack, and the refrigerant at the outlet of the battery pack heat exchanger 90 is a low-temperature low-pressure refrigerant.

[0131] The refrigerant at the other end of the second in-car heat exchanger 204 and the refrigerant at the outlet of the battery pack heat exchanger 90 are combined and flow to the gas-liquid separator, which separates the refrigerant from the refrigeration oil, and at the same time, the gas-liquid separator functions as an intermediate storage for the refrigerant (gas) to ensure stable suction of the compressor 201, and finally the refrigerant returns to the compressor 201, thereby forming a cycle.

[0132] When the four-way valve 104 adopts the first working mode, the vehicle-mounted refrigerator 100 operates independently.

[0133] Referring to FIG. 17, when the battery pack heat exchanger 90 is in the battery pack cooling mode and the four-way valve 104 is in the first working mode, the fourth on-off valve 60, the first throttling valve 70, the first one-way valve 250, and the fifth on-off valve 230 are closed, the first on-off valve 30, the second on-off valve 40, the second one-way valve 260, and the sixth on-off valve 240 are opened, and the second throttling valve 80, the third throttling valve 210, and the fourth throttling valve 220 are opened.

[0134] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, the compressor 201 is connected to the first vehicle interior heat exchanger 202 (without wind passing through), and the first vehicle interior heat exchanger 202 only serves as a flow channel. At this time, the other end of the first vehicle interior heat exchanger 202 is still high-temperature and high-pressure refrigerant (gas). The other end of the first vehicle interior heat exchanger 202 is connected to the vehicle exterior heat exchanger 203 through the second on-off valve 40, and the refrigerant exchanges heat with the environment through the vehicle exterior heat exchanger 203. The refrigerant is cooled by heat release, and the outlet of the vehicle exterior heat exchanger 203 is medium-temperature and high-pressure refrigerant (which can be liquid or gas, determined by the environment temperature).

[0135] The refrigerant is throttled and cooled by the third throttling valve 210, and becomes low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the third throttling valve 210 is connected to the battery pack heat exchanger 90, which functions as an evaporator at this time. The high-temperature refrigerant from the battery pack heat exchanger 90 is cooled to low-temperature refrigerant by the battery pack heat exchanger 90, which provides cooling to the battery pack. The refrigerant at the outlet of the battery pack heat exchanger 90 is low-temperature and low-pressure refrigerant.

[0136] The refrigerant at the outlet of the battery pack heat exchanger 90 flows to the gas-liquid separator, which separates the refrigerant and the refrigeration oil. At the same time, the gas-liquid separator serves as an intermediate storage for the refrigerant (gas), ensuring stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thus forming a cycle.

[0137] When the four-way valve 104 adopts the first working mode, the vehicle-mounted refrigerator 100 operates independently.

[0138] Referring to FIG. 21, when the air conditioning module 20 is in heating mode and the battery pack heat exchanger 90 is in battery pack heating mode, and the four-way valve 104 is in the third working mode, the third on-off valve 50, the fifth on-off valve 230, the fourth on-off valve 60, and the first one-way valve 250 are opened, and the first on-off valve 30, the second on-off valve 40, the second one-way valve 260, and the sixth on-off valve 240 are closed. At the same time, the first throttling valve 70, the third throttling valve 210, and the fourth throttling valve 220 are all opened to function as throttling and cooling.

[0139] The compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, which is divided into two branches:

[0140] First branch: The compressor 201 is connected to the first vehicle interior heat exchanger 202 (with wind passing through), and the low-temperature air is heated to high-temperature air by the first vehicle interior heat exchanger 202 to provide heating to the vehicle interior. The refrigerant is cooled to medium-temperature and high-pressure refrigerant by the first vehicle interior heat exchanger 202. The other end of the first vehicle interior heat exchanger 202 is connected to the first throttling valve 70, and the refrigerant is throttled and cooled by the first throttling valve 70 to become low-temperature and low-pressure wet steam or supercooled liquid.

[0141] The second branch: the compressor 201 enters the battery pack heat exchanger 90 through the fifth on-off valve 230 and the fourth throttle valve 220. The low-temperature battery pack is heated by the battery pack heat exchanger 90, and the temperature of the low-temperature battery pack is raised. The refrigerant is cooled to medium-temperature high-pressure refrigerant by the battery pack heat exchanger 90. The outlet of the battery pack heat exchanger 90 is connected to the third throttle valve 210, and the refrigerant is throttled and cooled by the third throttle valve 210 to become low-temperature low-pressure wet steam or supercooled liquid. The outlet of the third throttle valve 210 and the outlet of the first throttle valve 70 are combined, and the refrigerant flows to the plate heat exchanger 102 through the third on-off valve 50. At this time, the plate heat exchanger 102 is an evaporator, and the refrigerant is heated by the ambient air or the motor waste heat to complete the process of absorbing heat from the environment, thereby realizing the heating of the vehicle-mounted refrigerator. The refrigerant at the outlet of the plate heat exchanger 102 is low-temperature low-pressure refrigerant. The outlet of the plate heat exchanger 102 is connected to the gas-liquid separator through the fourth on-off valve 60. The gas-liquid separator separates the refrigerant and the refrigeration oil, and at the same time, the gas-liquid separator acts as a refrigerant (gas) intermediate storage device to ensure stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thereby forming a cycle.

[0142] Since the inlet temperature of the battery pack heat exchanger 90 exceeds a certain range, the local temperature of the battery pack is easy to exceed its working temperature range, so the required temperature of the first vehicle heat exchanger 202 needs to continue to rise (for example, the target temperature is 95°C), and when the inlet temperature of the battery pack heat exchanger 90 reaches the upper limit (for example, the upper limit temperature is 65°C), the valve opening of the fourth throttle valve 220 is reduced to reduce the inlet temperature of the battery pack heat exchanger 90. The fourth throttle valve 220 realizes control of different heating temperatures when it is opened.

[0143] Referring to FIG. 22, when the air conditioning module 20 is not running, the battery pack heat exchanger 90 is in the battery pack heating mode, and the four-way valve 104 is in the third working mode, the third on-off valve 50, the fourth on-off valve 60, the fifth on-off valve 230 and the first one-way valve 250 are opened, the first on-off valve 30, the second on-off valve 40, the second one-way valve 260 and the sixth on-off valve 240 are closed, and at the same time, the first throttle valve 70 and the second throttle valve 80 are closed, and the third throttle valve 210 and the fourth throttle valve 220 are opened to have a throttling and cooling effect.

[0144] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, it enters the battery pack heat exchanger 90 through the fifth on-off valve 230 and the fourth throttling valve 220. The low-temperature battery is heated by the battery pack heat exchanger 90, and the temperature of the refrigerant is cooled to a medium-temperature and high-pressure fluid by the battery pack heat exchanger 90. The outlet of the battery pack heat exchanger 90 is connected to the third throttling valve 210, and the refrigerant is throttled and cooled by the third throttling valve 210 to become a low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant flows to the plate heat exchanger 102 through the third on-off valve 50, at which time the plate heat exchanger 102 is an evaporator, and the refrigerant is heated by the ambient air or motor waste heat to complete the process of absorbing heat from the environment, thereby realizing heating of the vehicle-mounted refrigerator 100. The refrigerant at the outlet of the plate heat exchanger 102 is a low-temperature and low-pressure fluid. The outlet of the plate heat exchanger 102 is connected to the gas-liquid separator through the fourth on-off valve 60, and the gas-liquid separator separates the refrigerant and the refrigeration oil, and serves as an intermediate storage for the refrigerant (gas) to ensure stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thereby forming a cycle.

[0145] Referring to FIGS. 13 and 24, when the air conditioning module 20 is in the air conditioning defrosting mode, the fourth on-off valve 104 is in the second working mode, the fifth on-off valve 230, the sixth on-off valve 240, the second on-off valve 40, the first one-way valve 250, the second one-way valve 260, and the first on-off valve 30 are closed, the third on-off valve 50 and the fourth on-off valve 60 are opened, the fourth throttling valve 220 and the third throttling valve 210 are closed, and the first throttling valve 70 is opened for throttling.

[0146] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, it is connected to the first vehicle interior heat exchanger 202 (with air passing through), and the low-temperature air is heated to high-temperature air by the first vehicle interior heat exchanger 202 and blown to the glass to remove the fog, and the refrigerant is cooled to a medium-temperature and high-pressure fluid by the first vehicle interior heat exchanger 202.

[0147] The other end of the first vehicle interior heat exchanger 202 is connected to the first throttling valve 70, and the refrigerant is throttled and cooled by the first throttling valve 70 to become a low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the first throttling valve 70 is connected to the plate heat exchanger 102 through the third on-off valve 50, at which time the plate heat exchanger 102 is an evaporator, and the refrigerant is heated by the ambient air or motor waste heat to complete the process of absorbing heat from the environment, thereby realizing heating of the vehicle-mounted refrigerator 100. The refrigerant at the outlet of the plate heat exchanger 102 is a low-temperature and low-pressure fluid. The outlet of the plate heat exchanger 102 is connected to the gas-liquid separator through the fourth on-off valve 60, and the gas-liquid separator separates the refrigerant and the refrigeration oil, and serves as an intermediate storage for the refrigerant (gas) to ensure stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thereby forming a cycle.

[0148] The vehicle-mounted refrigerator 100 comprises a semiconductor refrigerating sheet, the semiconductor refrigerating sheet exchanges heat with the auxiliary heat exchange module 3, and the semiconductor refrigerating sheet is powered to realize refrigeration or heating of the vehicle-mounted refrigerator 100. Thus, the semiconductor refrigerating sheet can be directly powered to realize normal use of the vehicle-mounted refrigerator 100, so that the vehicle-mounted refrigerator 100 can be independently operated.

[0149] According to some embodiments of the present application, referring to FIG. 25 and FIG. 26, the vehicle-mounted refrigerator 100 comprises a refrigerator heat exchange system 4, which comprises a refrigerator compressor 41, a first refrigerator heat exchanger 42, and a second refrigerator heat exchanger 44 connected to form a second refrigerant circuit. The second refrigerator heat exchanger 44 is adapted to exchange heat with the auxiliary heat exchange module 3. In this way, the vehicle-mounted refrigerator 100 can make full use of the refrigerator compressor 41, the first refrigerator heat exchanger 42, and the second refrigerator heat exchanger 44 in the second refrigerant circuit to independently operate for refrigeration or heating, so as to ensure that the vehicle-mounted refrigerator 100 can continuously and stably operate when the vehicle stops running, and ensure that the vehicle-mounted refrigerator 100 can store food at a constant temperature.

[0150] Further, referring to FIG. 25 and FIG. 26, the thermal management system 200 further comprises a refrigerator throttling device 43, one end of the refrigerator throttling device 43 is connected with the second refrigerator heat exchanger 44, and the other end of the refrigerator throttling device 43 is connected with the refrigerator compressor 41. The refrigerator throttling device 43 can throttle and cool the refrigerant in the second refrigerant circuit, so as to throttle and cool the refrigerant (gas) flowing out of the refrigerator compressor 41, and the cooled refrigerant is separated from refrigeration oil in the gas-liquid separator in the second refrigerant circuit, while the gas-liquid separator serves as an intermediate storage of the refrigerant (gas), ensuring stable suction of the refrigerator compressor 41, and finally the refrigerant returns to the refrigerator compressor 41.

[0151] Referring to FIG. 26, when the air conditioning module 20 is in a refrigeration mode and simultaneously refrigerates the refrigerator, and the four-way valve 104 is in a first working mode, the first on-off valve 30 and the second on-off valve 40 are opened, the fourth on-off valve 60 and the first throttling valve 70 are closed, and the second throttling valve 80 and the refrigerator throttling device 43 are opened to throttle and cool.

[0152] After the compressor 201 discharges high-temperature and high-pressure refrigerant (gas) after compression, the compressor 201 is connected with the first vehicle interior heat exchanger 202 (without air passing through), and the first vehicle interior heat exchanger 202 only serves as a flow channel. At this time, the other end of the first vehicle interior heat exchanger 202 is still high-temperature and high-pressure refrigerant (gas). The other end of the first vehicle interior heat exchanger 202 is connected with the vehicle exterior heat exchanger 203 through the second on-off valve 40, the refrigerant exchanges heat with the environment through the vehicle exterior heat exchanger 203, the refrigerant releases heat, and the outlet of the vehicle exterior heat exchanger 203 is medium-temperature and high-pressure refrigerant (which can be liquid or gas, determined by the environment temperature).

[0153] The vehicle exterior heat exchanger 203 is connected with the second throttling valve 80. The refrigerant is throttled and cooled by the second throttling valve 80, and becomes low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the second throttling valve 80 is connected with the second vehicle interior heat exchanger 204. At this time, high-temperature air passes through the second vehicle interior heat exchanger 204. The second vehicle interior heat exchanger 204 functions as an evaporator. The high-temperature air is cooled to low-temperature air and is provided to the vehicle interior to perform refrigeration. The refrigerant at the other end of the second vehicle interior heat exchanger 204 is low-temperature and low-pressure refrigerant. The other end of the second vehicle interior heat exchanger 204 is connected with a gas-liquid separator. The gas-liquid separator separates the refrigerant and the refrigeration oil. Meanwhile, the gas-liquid separator functions as an intermediate storage device of the refrigerant (gas), and ensures stable suction of the compressor 201. Finally, the refrigerant returns to the compressor 201, thereby forming a cycle.

[0154] After the refrigerator compressor 41 discharges high-temperature and high-pressure refrigerant (gas), the refrigerant is connected with the second refrigerator heat exchanger 44. The refrigerant exchanges heat with the auxiliary heat exchange module 3 through the second refrigerator heat exchanger 44. The refrigerant releases heat. The outlet of the second refrigerator heat exchanger 44 is medium-temperature and high-pressure refrigerant (which can be liquid or gas, determined by the ambient temperature). The second refrigerator heat exchanger 44 is connected with a refrigerator throttling device 43. The refrigerant is throttled and cooled by the refrigerator throttling device 43, and becomes low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the refrigerator throttling device 43 is connected with the first refrigerator heat exchanger 42. At this time, high-temperature air passes through the first refrigerator heat exchanger 42. The first refrigerator heat exchanger 42 functions as an evaporator. The high-temperature air is cooled to low-temperature air and is provided to the vehicle-mounted refrigerator 100 to perform refrigeration. The refrigerant at the outlet of the first refrigerator heat exchanger 42 is low-temperature and low-pressure refrigerant. The outlet of the first refrigerator heat exchanger 42 is connected with a gas-liquid separator. The gas-liquid separator separates the refrigerant and the refrigeration oil. Meanwhile, the gas-liquid separator functions as an intermediate storage device of the refrigerant (gas), and ensures stable suction of the refrigerator compressor 41. Finally, the refrigerant returns to the refrigerator compressor 41, thereby forming a cycle.

[0155] The four-way valve 104 is in the first working mode. The refrigerant is cooled and cooled by the motor heat exchanger 103, and then enters the auxiliary heat exchange module 3 and / or the motor 101 to absorb heat and carry away heat, thereby achieving refrigeration of the vehicle-mounted refrigerator 100.

[0156] Therefore, the auxiliary heat exchange module 3 and the second refrigerator heat exchanger 44 are arranged together, and the auxiliary heat exchange module 3 is used to carry away the waste heat discharged by the refrigerator heat exchange system 4. Since the auxiliary heat exchange module 3 borrows the vehicle exterior heat exchanger 203 and / or the motor heat exchanger 103 to dissipate heat, the heat dissipation is sufficient, which is conducive to increasing the refrigeration efficiency of the vehicle-mounted refrigerator 100, and overcoming the problems of insufficient refrigeration capacity and low efficiency caused by insufficient heat dissipation of the refrigerator heat exchange system 4.
