[0087] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 18 The thermal management system 100 according to the embodiment of the present invention is described. The thermal management system 100 includes: an air conditioning module 10 , a refrigerator module 20 , and a heat exchange module 30 .

[0088] Specifically, if Figure 1 and Figure 2 As shown, the air-conditioning module 10 includes a compressor 11, an in-vehicle heat exchanger and an out-vehicle heat exchanger connected to form a refrigerant circuit; the refrigerator module 20 includes a heating unit and a refrigeration unit, and the heating unit and the refrigeration unit are respectively connected to the refrigerant circuit; the heat exchange module 30 is arranged between the heating unit and the refrigeration unit, and the heating unit and the refrigeration unit can exchange heat through the heat exchange module 30.

[0089] In the present application, the heat exchange module 30 is arranged between the refrigerator module 20 and the air conditioning module 10 to realize the heat exchange between the refrigerator and the air conditioning, and the cooling or heating of the refrigerator module 20 and the cooling or heating of the air conditioning module 10 can work independently. When it is necessary to heat the interior of the vehicle or the refrigerator module 20, the thermal management system 100 controls the refrigerant flowing through to meet the requirements of raising the interior temperature of the vehicle in cold weather and heating the food and beverages in the heating unit, so as to meet the requirements of lowering the interior temperature of the vehicle in hot weather and refrigerating the food and beverages in the refrigeration unit.

[0090] According to the thermal management system 100 of the embodiment of the present invention, a heat exchange unit is set between the refrigeration unit and the heating unit so that while the refrigeration unit and the heating unit can work independently to achieve heat exchange, the heat exchange module 30 can assist the work of the refrigeration unit and the heating unit to achieve regulation of the temperature in the refrigerator, increase the utilization of the heat generated in the thermal management system 100, and enable the heating unit and the refrigeration unit to work at the same time to achieve the functions of preparing hot drinks and refrigerating and preserving food, reduce the reduction in cooling capacity and cooling efficiency in the thermal management system 100 due to pressure loss, so that the refrigerator module 20 and the air-conditioning module 10 can maintain a high-efficiency mode when working at the same time.

[0091] In some embodiments, Figure 1 As shown, the heating unit includes a heating box 211, the cooling unit includes a cooling box 221, and the heat exchange module 30 is arranged between the heating box 211 and the cooling box 221. Both sides of the heat exchange module 30 in the thickness direction are in contact with the corresponding side walls of the heating box 211 and the cooling box 221 to achieve heat exchange between the cooling box 221 and the heating box 211, thereby changing the temperature in the cooling box 221 and the heating box 211.

[0092] Furthermore, a heating chamber is defined in the heating box 211, and a cooling chamber is defined in the cooling box 221; the heat exchange module 30 includes a hot end 32 and a cold end 33, the hot end 32 is arranged outside the side wall of the heating chamber, and the cold end 33 is arranged outside the side wall of the cooling chamber, and heat is exchanged between the hot end 32 and the cold end 33. When the heat exchange module 30 is working, the cold end 33 absorbs heat from the cooling box 221 and transfers it to the hot end 32 and then to the heating box 211. The heat exchange module 30 can also reversely supply power to cool the cooling box 221.

[0093] In addition, the heating unit includes a heating heat exchanger 212, which is disposed outside the side wall of the heating cavity; the cooling unit includes a cooling heat exchanger 222, which is disposed outside the side wall of the cooling cavity.

[0094] For example, taking the cooling of the air-conditioning module 10 as an example, when the refrigeration box 221 and the air-conditioning module 10 are turned on the cooling mode at the same time, the refrigerant enters the evaporator 122 and the refrigeration heat exchanger 222 in the vehicle after throttling. Since the outlets of the two heat exchangers merge and enter the suction port of the compressor 11 together, the pressures of the two are the same. According to the refrigeration principle, the evaporation temperature of the refrigerant flowing through the refrigeration box 221 and the refrigeration heat exchanger 222 is also the same as the evaporation temperature of the refrigerant in the evaporator 122 in the vehicle. Based on the requirement of air conditioning use, the evaporation temperature is about 0-5°C. The medium-temperature refrigerant of about 0-5°C flows into the refrigeration of the refrigeration box 221. Heat exchanger 222, since the target temperature of refrigeration box 221 is 0-10°C, refrigeration heat exchanger 222 can provide a part of the cooling capacity to help cool down the items in refrigeration box 221; at the same time, a heat exchange module 30 is arranged between refrigeration box 221 and heating box 211, the cold end 33 of heat exchange module 30 is in contact with refrigeration box 221, and the hot end 32 is in contact with heating box 211, the heat exchange module 30 is powered on, the cold end 33 absorbs heat from refrigeration box 221 and is transferred to the hot end 32 and then to heating box 211, the refrigeration heat exchanger 222 and the heat exchange module 30 work synchronously to absorb and take away the heat in refrigeration box 221, and complete the whole refrigeration cycle. In this way, when refrigeration box 221 does not need refrigeration heat exchanger 222 to provide too low a temperature, it can also meet the functional requirements of refrigeration in refrigeration box 221 (the temperature in refrigerator module 20 is about 5°C at this time).

[0095] In addition, the refrigerant flow path of the vehicle passenger compartment air conditioner can cool the passenger compartment according to its own evaporation temperature requirements, without artificially reducing the pressure before merging with the refrigerant circuit of the refrigeration box 221 and then entering the compressor 11, which can reduce the reduction in cooling capacity and cooling efficiency caused by pressure loss. At the same time, the heat transported from the refrigeration box 221 is effectively recovered to meet part or all of the heat demand in the heating box 211.

[0096] In some embodiments, the heating heat exchanger 212 is disposed on at least one of the multiple side walls of the heating cavity except the side wall provided with the hot end 32, and the cooling heat exchanger 222 is disposed on at least one of the multiple side walls of the cooling cavity except the side wall provided with the cold end 33. That is, the hot end 32 is disposed on one of the multiple side walls of the heating cavity, and the heating heat exchanger 212 is disposed on another side wall of the multiple side walls, and the heating heat exchanger 212 and the hot end 32 are located on different side walls. Similarly, it can be known that the positional relationship between the cooling heat exchanger 222 and the cold end 33 is set, which will not be described in detail here.

[0097] In this embodiment, the heating heat exchanger 212 is arranged on the heating cavity, and the side wall of the heating heat exchanger 212 is opposite to the side wall of the hot end 32; the cooling heat exchanger 222 is arranged on the cooling cavity, and the side wall of the cooling heat exchanger 222 is opposite to the side wall of the cold end 33. That is, when the heat exchange module 30 is arranged, the heat exchange module 30 is arranged between the refrigeration box 221 and the heating box 211, and the cold end 33 of the heat exchange module 30 contacts the refrigeration box 221, and the hot end 32 of the heat exchange module 30 contacts the heating box 211, so as to adjust the temperature in the heating box 211 and the refrigeration box 221. The heating heat exchanger 212 is arranged on the side of the heating box 211 away from the heat exchange module 30, and the cooling heat exchanger 222 is arranged on the side of the cooling box 221 away from the heat exchange module 30. The heating heat exchanger 212 and the cooling heat exchanger 222 can be arranged on the outer wall of the corresponding box by sticking, so as to facilitate heat exchange with the corresponding box.

[0098] In some embodiments, the heat exchange module 30 includes a semiconductor refrigeration chip. A semiconductor refrigeration chip is also called a thermoelectric refrigeration chip, which is a heat pump. The principle of a semiconductor refrigeration chip is mainly based on the Peltier effect. The Peltier effect states that when an electric current passes through the interface of two different conductors, heat is absorbed or released at the interface. In a semiconductor refrigeration chip, this effect is achieved by passing a direct current through a galvanic couple formed by two different types of semiconductor materials (P-type and N-type semiconductors) in series. When the current flows from the N-type semiconductor to the P-type semiconductor, one end of the galvanic couple absorbs heat to form a cold end 33; and when the current flows from the P-type semiconductor to the N-type semiconductor, the other end of the galvanic couple releases heat to form a hot end 32. The main advantage of this refrigeration technology is that it does not require moving parts, so it has high reliability and no refrigerant pollution. The semiconductor refrigeration chip has the characteristics of high precision, long life and small size.

[0099] In some embodiments, the in-vehicle heat exchanger includes: an in-vehicle evaporator 122, and the refrigeration unit includes a refrigeration heat exchanger 222, and the refrigeration heat exchanger 222 is connected in parallel with the in-vehicle evaporator 122. That is, the in-vehicle evaporator 122 and the refrigeration heat exchanger 222 can work independently to achieve heat exchange in the vehicle and heat exchange in the refrigerator.

[0100] In some embodiments, the in-vehicle heat exchanger further includes: an in-vehicle condenser 121, and the heating unit includes a heating heat exchanger 212, and the heating heat exchanger 212 is connected in parallel with the in-vehicle condenser 121. For example, the refrigerator can be heated or cooled separately, or the refrigerator and the air conditioner can be heated or cooled simultaneously.

[0101] In some embodiments, Figure 2 As shown, the first end of the in-vehicle condenser 121 and the first end of the heating heat exchanger 212 are both connected to the outlet of the compressor 11, the second end of the in-vehicle condenser 121 and the second end of the heating heat exchanger 212 are both connected to the first end of the outdoor heat exchanger, and the outdoor heat exchanger can be selectively connected to at least one of the in-vehicle condenser 121 and the heating heat exchanger 212; the first end of the in-vehicle evaporator 122 and the first end of the cooling heat exchanger 222 are both connected to the second end of the outdoor heat exchanger, the second end of the in-vehicle evaporator 122 and the second end of the cooling heat exchanger 222 are both connected to the inlet of the compressor 11, and the outdoor heat exchanger can be selectively connected to at least one of the in-vehicle evaporator 122 and the cooling heat exchanger 222.

[0102] That is, there are different refrigerant circuits in the thermal management system 100. When the air-conditioning module 10 is cooling or heating, the heat exchange module 30 is cooling or heating, the refrigerator module 20 is cooling or heating, or when at least two of the air-conditioning module 10, the heat exchange module 30 and the refrigerator module 20 are combined, the refrigerant circuit is selectively adjusted to enable the thermal management system 100 to operate in different modes.

[0103] In some embodiments, the outdoor heat exchanger includes a first outdoor heat exchanger 131 and a second outdoor heat exchanger 132, the first end of the first outdoor heat exchanger 131 and the first end of the second outdoor heat exchanger 132 are connected to the second end of the indoor condenser 121 and the second end of the heating heat exchanger 212, and one of the first outdoor heat exchanger 131 and the second outdoor heat exchanger 132 can be selectively connected to at least one of the indoor condenser 121 and the heating heat exchanger 212.

[0104] For example, in the air conditioning cooling mode, the refrigerant flows through the compressor 11 and the in-vehicle condenser 121 to the first exterior heat exchanger to cool the passenger compartment of the vehicle.

[0105] The second end of the first external heat exchanger 131 and the second end of the second external heat exchanger 132 are connected to the first end of the in-vehicle evaporator 122 and the first end of the cooling heat exchanger 222, and one of the first external heat exchanger 131 and the second external heat exchanger 132 can be selectively connected to at least one of the in-vehicle evaporator 122 and the cooling heat exchanger 222. For example, in the air conditioning cooling mode, the refrigerant flows to the in-vehicle evaporator 122 through the in-vehicle condenser 121 and the first external heat exchanger 131 and flows back to the compressor 11, and at this time, the second end of the first external heat exchanger 131 is connected to the first end of the in-vehicle evaporator 122. For another example, when the refrigeration unit is synchronously cooled in the air conditioning cooling mode, the refrigerant flows through the in-vehicle condenser 121 and the first external heat exchanger 131 and then flows to the in-vehicle evaporator 122 and the cooling heat exchanger 222 respectively, and at this time, the second end of the first external heat exchanger 131 is connected to the first end of the cooling heat exchanger 222 and the first end of the in-vehicle evaporator 122.

[0106] In some embodiments, Figure 2 As shown, the thermal management system 100 further includes: a first on-off valve 41 and a second on-off valve 42. The first on-off valve 41 is connected between the second end of the in-vehicle condenser 121 and the first end of the first external heat exchanger 131 and the first end of the second external heat exchanger 132, that is, after the refrigerant flows out of the in-vehicle condenser 121, it can selectively flow to the first external heat exchanger 131 or the second external heat exchanger 132 according to demand. The second on-off valve 42 is connected between the first on-off valve 41 and the first end of the first external heat exchanger 131. The second on-off valve 42 can control the operation of the first external heat exchanger 131. When the second on-off valve 42 is turned on, the first external heat exchanger 131 works, and when the second on-off valve 42 is turned off, the first external heat exchanger 131 does not work.

[0107] Furthermore, the thermal management system 100 further includes: a first throttle valve 55, the first throttle valve 55 being connected between the second end of the first external heat exchanger 131 and the second end of the second external heat exchanger 132 and the first end of the internal evaporator 122. The first throttle valve 55 is used to control the operation of the internal evaporator 122 and to adjust the flow of the refrigerant flowing through the internal evaporator 122 to achieve control of the heat exchange amount.

[0108] In some embodiments, Figure 2 As shown, the thermal management system 100 has at least an air conditioning and cooling mode.

[0109] The compressor 11 discharges high-temperature and high-pressure gas after compression. The compressor 11 is connected to the in-vehicle condenser 121. At this time, the in-vehicle condenser 121 only flows through as a flow channel. The high-temperature and high-pressure gas is connected to the first external heat exchanger 131 through the outlet of the in-vehicle condenser 121 through the second on-off valve 42. The refrigerant exchanges heat with the environment through the first external heat exchanger 131, and the refrigerant releases heat. The outlet of the first external heat exchanger 131 is a medium-temperature and high-pressure fluid. The in-vehicle evaporator 122 is connected to the first throttle valve 55. The refrigerant is throttled and cooled through the first throttle valve 55, and becomes low-temperature and low-pressure wet steam or supercooled liquid; the outlet of the first throttle valve 55 is connected to the in-vehicle evaporator 122. At this time, high-temperature air passes through the in-vehicle evaporator 122. The in-vehicle evaporator 122 acts as an evaporator. The high-temperature air is cooled to low-temperature air and provided to the vehicle for refrigeration. The refrigerant at the outlet of the in-vehicle evaporator 122 is a low-temperature and low-pressure fluid. The outlet of the in-vehicle evaporator 122 is connected to the gas-liquid separator 90, which separates the refrigerant and the refrigeration oil and serves as an intermediate storage of the refrigerant gas to ensure stable air suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0110] In some embodiments, Figure 5 As shown, the thermal management system 100 also includes: a third on-off valve 43, a fourth on-off valve 44, and a second throttle valve 51. The third on-off valve 43 is connected between the first on-off valve 41 and the first end of the second external heat exchanger 132; the fourth on-off valve 44 is connected between the second end of the first external heat exchanger 131 and the second end of the second external heat exchanger 132 and the inlet of the compressor 11, and one of the first external heat exchanger 131 and the second external heat exchanger 132 can be selectively connected to the in-vehicle evaporator 122, the refrigeration heat exchanger 222 and at least one of the branches where the fourth on-off valve 44 is located; the second throttle valve 51 is connected between the second end of the in-vehicle condenser 121 and the first end of the first external heat exchanger 131, and the second throttle valve 51 is connected in parallel with the first on-off valve 41.

[0111] In some embodiments, Figure 5 As shown, the thermal management system 100 has at least an air conditioning heating mode.

[0112] In the air conditioning heating mode, the compressor 11 discharges high-temperature and high-pressure gas after compression. The compressor 11 is connected to the in-vehicle condenser 121. The low-temperature air is heated to high-temperature air through the in-vehicle condenser 121 and provided to the vehicle for heating. The refrigerant is cooled to medium-temperature and high-pressure fluid through the in-vehicle condenser 121. The outlet of the in-vehicle condenser 121 is connected to the second throttle valve 51. The refrigerant is throttled and cooled by the second throttle valve 51 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the second throttle valve 51 is connected to the second The external heat exchanger 132 is connected. At this time, the second external heat exchanger 132 is an evaporator. The refrigerant is heated by the ambient air or the waste heat of the motor cooling module 80 to complete the heat absorption process from the environment. The refrigerant at the outlet of the second external heat exchanger 132 is a low-temperature and low-pressure fluid; the outlet of the second external heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0113] In some embodiments, the thermal management system 100 further includes: a third throttle valve 54 connected between the second end of the first external heat exchanger 131 and the second end of the second external heat exchanger 132 and the first end of the refrigeration heat exchanger 222 .

[0114] In some embodiments, Figure 3 As shown, the thermal management system 100 has at least an air-conditioning and refrigeration unit synchronous cooling mode; when the thermal management system 100 is in the air-conditioning and refrigeration unit synchronous cooling mode, the heat exchange module 30 is turned on, the first on-off valve 41, the second on-off valve 42, the third throttle valve 54 and the first throttle valve 55 are turned on, the second throttle valve 51, the third on-off valve 43 and the fourth on-off valve 44 are turned off, the first external heat exchanger 131 acts as a condenser, and the refrigeration heat exchanger 222 and the internal evaporator 122 act as evaporators.

[0115] That is, when the air conditioning of the thermal management system 100 is cooling and the refrigeration unit is cooling at the same time, the compressor 11 discharges high-temperature and high-pressure gas after compression, and is connected to the in-vehicle condenser 121. At this time, the in-vehicle condenser 121 only serves as a flow channel, and the outlet of the in-vehicle condenser 121 is still high-temperature and high-pressure gas; the outlet of the in-vehicle condenser 121 is connected to the first outdoor heat exchanger 131 through the second on-off valve 42, and the refrigerant exchanges heat with the environment through the first outdoor heat exchanger 131, and the refrigerant releases heat, and the outlet of the first outdoor heat exchanger 131 is a medium-temperature and high-pressure fluid; the refrigerant forms two branches after passing through the first outdoor heat exchanger 131.

[0116] Among them, the two branches include a first branch and a second branch. In the first branch, the first external heat exchanger 131 is connected to the first throttle valve 55, and the refrigerant is throttled and cooled through the first throttle valve 55 to become low-temperature and low-pressure wet steam or supercooled liquid; the outlet of the first throttle valve 55 is connected to the in-vehicle evaporator 122. At this time, high-temperature air passes through the in-vehicle evaporator 122, and the in-vehicle evaporator 122 acts as an evaporator. The high-temperature air is cooled to low-temperature air and provided to the vehicle for refrigeration. The refrigerant at the outlet of the in-vehicle evaporator 122 is a low-temperature and low-pressure fluid.

[0117] In the second branch, the first off-board heat exchanger 131 is connected to the third throttle valve 54, and the refrigerant is throttled and cooled by the third throttle valve 54 to become low-temperature and low-pressure wet steam or supercooled liquid; the outlet of the third throttle valve 54 is connected to the refrigeration heat exchanger 222 of the refrigeration box 221, and the refrigeration heat exchanger 222 acts as an evaporator to take away part of the heat in the refrigeration box 221; at the same time, the semiconductor refrigeration plate is turned on to dissipate the heat to the heating box 211 on the other side, so as to provide the refrigeration box 221 with refrigeration in a synchronous and complementary manner using the refrigeration system and the semiconductor refrigeration plate, and the refrigerant at the outlet of the refrigeration heat exchanger 222 of the refrigeration box 221 is a low-temperature and low-pressure fluid; the outlet of the air-conditioning evaporator and the outlet of the refrigeration heat exchanger 222 of the refrigeration box 221 are connected to the gas-liquid separator 90 after merging, and the gas-liquid separator 90 separates the refrigerant and the refrigeration oil and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11, and finally the refrigerant returns to the electric compressor 11 to form a cycle.

[0118] In some embodiments, the thermal management system 100 also includes: a fourth throttle valve 52 and a fifth throttle valve 53, the fourth throttle valve 52 is connected between the outlet of the compressor 11 and the first end of the heating heat exchanger 212; the fifth throttle valve 53 is connected between the second end of the heating heat exchanger 212 and the second on-off valve 42.

[0119] In some embodiments, Figure 6 As shown, the thermal management system 100 has at least a synchronous heating mode of the air conditioning and heating unit; when the thermal management system 100 is in the synchronous heating mode of the air conditioning and heating unit, the heat exchange module 30 is turned on, the second throttle valve 51, the third on-off valve 43, the fourth on-off valve 44, the fourth throttle valve 52 and the fifth throttle valve 53 are turned on, the first on-off valve 41, the third throttle valve 54 and the first throttle valve 55 are turned off, the in-vehicle condenser 121 and the heating heat exchanger 212 act as condensers, and the second outdoor heat exchanger 132 acts as an evaporator.

[0120] That is, when the thermal management system 100 is in the synchronous heating state of the air conditioning and heating units, the compressor 11 discharges high-temperature and high-pressure gas after compression and flows into two branches, and the two branches include a third branch and a fourth branch. In the third branch, the outlet of the compressor 11 is connected to the in-vehicle condenser 121, and the low-temperature air is heated to high-temperature air through the in-vehicle condenser 121 and provided to the interior of the vehicle for heating, and the refrigerant is cooled to a medium-temperature and high-pressure fluid through the in-vehicle condenser 121; the outlet of the in-vehicle condenser 121 is connected to the second throttle valve 51, and the refrigerant is throttled and cooled through the second throttle valve 51 to become low-temperature and low-pressure wet steam or supercooled liquid.

[0121] In the fourth branch, the outlet of the compressor 11 is connected to the heating heat exchanger 212, and the refrigerant enters the heating heat exchanger 212 through the fourth throttle valve 52. The outlet of the fourth throttle valve 52 is connected to the heating heat exchanger 212 of the heating box 211. At this time, the heating heat exchanger 212 acts as a condenser, thereby providing heating to the heating box 211. When the heating capacity of the heat pump system of the air conditioner is insufficient and heat supplement is required, the semiconductor refrigeration plate can be turned on simultaneously to supplement the heat in the heating box 211 and transport the cold to the refrigeration box 221. The refrigerant at the outlet of the heating heat exchanger 212 is a medium-temperature and high-pressure fluid; the outlet of the heating heat exchanger 212 is connected to the fifth throttle valve 53, and the refrigerant passes through the fifth throttle valve 53. The flow is cooled and becomes low-temperature and low-pressure wet steam or supercooled liquid; the outlets of the second throttle valve 51 and the fifth throttle valve 53 are merged and connected to the second external heat exchanger 132 through the third on-off valve 43. At this time, the second external heat exchanger 132 is an evaporator, and the refrigerant is heated by the ambient air or the waste heat of the motor cooling module 80 to complete the heat absorption process from the environment. The refrigerant at the outlet of the second external heat exchanger 132 is a low-temperature and low-pressure fluid; the outlet of the second external heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil, and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0122] When the inlet temperature of the heating heat exchanger 212 exceeds a certain range, the local temperature in the heating box 211 is likely to exceed its operating temperature range. Therefore, when the required temperature of the in-vehicle condenser 121 needs to continue to rise (for example, the target temperature is 95°C), and the inlet temperature of the heating heat exchanger 212 reaches the upper limit (for example, the upper limit temperature is 65°C), the valve opening of the fourth throttle valve 52 can be reduced to reduce the inlet temperature of the heating heat exchanger 212. The fourth throttle valve 52 can realize the control of different heating temperatures in the dual-opening mode of air conditioning heating and heating unit heating.

[0123] In some embodiments, Figure 4As shown, the thermal management system 100 has at least a refrigeration unit refrigeration mode. When the thermal management system 100 is in the refrigeration unit refrigeration mode, the heat exchange module 30 is turned on, the first on-off valve 41, the second on-off valve 42 and the third throttle valve 54 are turned on, the second throttle valve 51, the fourth throttle valve 52, the third on-off valve 43, the fourth on-off valve 44 and the first throttle valve 55 are turned off, the first external heat exchanger 131 acts as a condenser, and the refrigeration heat exchanger 222 acts as an evaporator.

[0124] When the thermal management system 100 is in the refrigeration unit refrigeration mode, the compressor 11 discharges high-temperature and high-pressure gas after compression and is connected to the in-vehicle condenser 121. At this time, the in-vehicle condenser 121 serves as a flow channel, and the outlet of the in-vehicle condenser 121 is still high-temperature and high-pressure gas; the outlet of the in-vehicle condenser 121 is connected to the first external heat exchanger 131 through the second on-off valve 42, and the refrigerant exchanges heat with the environment through the first external heat exchanger 131, and the refrigerant releases heat, and the outlet of the first external heat exchanger 131 is a medium-temperature and high-pressure fluid; the first external heat exchanger 131 is connected to the third throttle valve 54, and the refrigerant is throttled and cooled by the third throttle valve 54 to become low-temperature and low-pressure wet steam or supercooled liquid; the outlet of the third throttle valve 54 The outlet is connected to the refrigeration heat exchanger 222 of the refrigeration box 221. At this time, the refrigeration heat exchanger 222 acts as an evaporator, taking away part of the heat in the refrigeration box 221; at the same time, the semiconductor refrigeration plate is turned on to dissipate the heat to the heating box 211 on the other side, so that the refrigeration system and the semiconductor refrigeration plate are synchronously and complementary to provide it to the refrigeration box 221 for refrigeration. The refrigerant at the outlet of the refrigeration heat exchanger 222 of the refrigeration box 221 is a low-temperature and low-pressure fluid; the refrigeration heat exchanger 222 of the refrigeration box 221 is connected to the gas-liquid separator 90, the gas-liquid separator 90 separates the refrigerant and the refrigeration oil, and acts as an intermediate storage of the refrigerant gas, to ensure the stable suction of the compressor 11, and finally the refrigerant returns to the compressor 11 to form a cycle.

[0125] In some embodiments, Figure 7 As shown, the thermal management system 100 has at least a heating unit heating mode. When the thermal management system 100 is in the heating unit heating mode, the fourth throttle valve 52, the fifth throttle valve 53, the third on-off valve 43 and the fourth on-off valve 44 are turned on, the second throttle valve 51, the first on-off valve 41, the second on-off valve 42, the third throttle valve 54 and the first throttle valve 55 are turned off, the heating heat exchanger 212 acts as a condenser, and the second external heat exchanger 132 acts as an evaporator.

[0126] When the thermal management system 100 is in the heating mode of the heating unit, the compressor 11 discharges high-temperature and high-pressure gas after compression, and enters the heating heat exchanger 212 through the fourth throttle valve 52. The outlet of the fourth throttle valve 52 is connected to the heating heat exchanger 212. At this time, the heating heat exchanger 212 acts as a condenser, thereby providing heating to the heating box 211 for heating. The outlet refrigerant of the heating heat exchanger 212 is a medium-temperature and high-pressure fluid; the outlet of the heating heat exchanger 212 is connected to the fifth throttle valve 53, and the refrigerant is throttled and cooled by the fifth throttle valve 53 to become low-temperature and low-pressure wet steam or supercooled liquid; the fifth throttle valve 53 is connected to the fifth throttle valve 53. The outlet of the valve 53 is connected to the second external heat exchanger 132 through the third on-off valve 43. At this time, the second external heat exchanger 132 is an evaporator, and the refrigerant is heated by the ambient air or the waste heat of the motor cooling module 80 to complete the heat absorption process from the environment. The outlet refrigerant of the second external heat exchanger 132 is a low-temperature and low-pressure fluid; the outlet of the second external heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil, and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0127] In addition, when the temperature of the items in the heating box 211 has reached the heating target temperature, it is only necessary to maintain the temperature in the box near the target temperature, and it is no longer necessary to heat the items. At this time, the heat demand is relatively small, and it is only necessary to turn on the semiconductor refrigeration sheet and use the heat dissipation of its hot end 32 to maintain the temperature in the heating box 211. At this time, the cold energy transported from the heating box 211 is transferred to the refrigeration box 221 for cold energy recovery, which can improve the overall efficiency.

[0128] In some embodiments, Figure 8 As shown, the thermal management system 100 has at least a cooling mode of the refrigeration unit and a heating mode of the heating unit; when the thermal management system 100 is in the cooling mode of the refrigeration unit and the heating mode of the heating unit, the heat exchange module 30 is turned on, the fourth throttle valve 52, the fifth throttle valve 53, the second on-off valve 42 and the third throttle valve 54 are turned on, the second throttle valve 51, the first on-off valve 41, the third on-off valve 43, and the fourth on-off valve 44 are turned off, the heating heat exchanger 212 and the first external heat exchanger 131 act as condensers, and the cooling heat exchanger 222 acts as an evaporator.

[0129] When the thermal management system 100 is in the cooling state of the refrigeration unit and the heating state of the heating unit, the compressor 11 discharges high-temperature and high-pressure gas after compression, and enters the heating heat exchanger 212 through the fourth throttle valve 52. The outlet of the fourth throttle valve 52 is directly or indirectly connected to the heating box 211. In this embodiment, the fifth throttle valve 53 is directly connected to the heating heat exchanger. At this time, the heating heat exchanger 212 acts as a condenser, thereby providing heating to the inside of the heating box 211. The outlet refrigerant of the heating heat exchanger 212 is a medium-temperature and high-pressure fluid; the outlet of the heating heat exchanger 212 is connected to the fifth throttle valve 53, and the fifth throttle valve 53 is completely It is opened and used as a flow path. The outlet of the fifth throttle valve 53 is connected to the first external heat exchanger 131 through the second on-off valve 42. At this time, the first external heat exchanger 131 is a condenser, which completes the process of heat dissipation to the environment. The outlet of the first external heat exchanger 131 is connected to the refrigeration box 221 through the third throttle valve 54 to cool the refrigeration box 221 and the cold storage material. After that, the low-temperature and low-pressure refrigerant enters the gas-liquid separator 90. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and acts as an intermediate storage for the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0130] When the temperature of the items in the heating box 211 has reached the heating target temperature, it is only necessary to maintain the temperature in the box near the target temperature (for example, 45°C), and it is no longer necessary to heat the items; and the temperature of the items in the refrigerating box 221 has also reached the refrigerating target temperature, and it is only necessary to maintain the temperature in the box near the target temperature (for example, 5°C), and it is no longer necessary to cool the hot items. At this time, the demand for cooling capacity and heating capacity in the refrigerating box 221 and the heating box 211 is relatively small, and it is only necessary to turn on the semiconductor refrigerating sheet, and use the heat dissipation of its hot end 32 to maintain the high temperature in the heating box 211, and the heat absorption of the cold surface to maintain the low temperature in the refrigerating box 221. At this time, the cold capacity transported from the heating box 211 is transferred to the refrigerating box 221 for cold capacity recovery to improve the overall efficiency.

[0131] In some embodiments, the thermal management system 100 has at least one of an air-conditioning dehumidification mode and an air-conditioning demisting mode.

[0133] The compressor 11 discharges high-temperature and high-pressure gas after compression, and is connected to the in-vehicle condenser 121. The in-vehicle condenser 121 releases heat as needed. At this time, the outlet of the in-vehicle condenser 121 is still high-temperature and high-pressure gas; the outlet of the in-vehicle condenser 121 is connected to the first external heat exchanger 131 through the second on-off valve 42, and the refrigerant exchanges heat with the environment through the first external heat exchanger 131, and the refrigerant releases heat.

The refrigerant at the outlet of the in-vehicle evaporator 122 is a low-temperature and low-pressure fluid. The outlet of the in-vehicle evaporator 122 is connected to the gas-liquid separator 90, which separates the refrigerant and the refrigeration oil, and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11.

Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0144] In some embodiments, Fig.12 As shown, the thermal management system 100 has at least an air conditioner, a battery pack, and a refrigeration unit synchronous cooling mode.

[0150] In some embodiments, Fig.13 As shown, the thermal management system 100 has at least a battery pack and a refrigeration unit synchronous cooling mode.

[0151] When the thermal management system 100 is in the synchronous cooling mode of the battery pack and the refrigeration unit, the heat exchange module 30 is turned on, the first on-off valve 41, the second on-off valve 42, the first one-way valve 62, the sixth throttle valve 56, the seventh throttle valve 57, the fifth on-off valve 46 and the third throttle valve 54 are turned on, the fourth throttle valve 52, the second throttle valve 51, the third on-off valve 43, the fourth on-off valve 44, the fifth throttle valve 53, the sixth on-off valve 45 and the first throttle valve 55 are turned off, the first external heat exchanger 131 acts as a condenser, the battery pack heat exchanger 70 and the refrigeration heat exchanger 222 act as evaporators.

[0152] That is, when the thermal management system 100 cools the battery pack, the refrigeration unit included in the refrigerator cools synchronously, and the compressor 11 discharges high-temperature and high-pressure gas after compression. The outlet of the compressor 11 is connected to the in-vehicle condenser 121. At this time, the in-vehicle condenser 121 only serves as a flow channel, and the outlet of the in-vehicle condenser 121 is still high-temperature and high-pressure gas. The outlet of the in-vehicle condenser 121 is connected to the first external heat exchanger 131 through the second on-off valve 42. The refrigerant exchanges heat with the environment through the first external heat exchanger 131, and the refrigerant releases heat. The outlet of the first external heat exchanger 131 is a medium-temperature and high-pressure fluid. After the refrigerant passes through the first external heat exchanger 131, two branches are formed.

[0153] The two branches include the tenth branch and the eleventh branch. In the tenth branch, the first off-board heat exchanger 131 is connected to the sixth throttle valve 56. The refrigerant is throttled and cooled through the sixth throttle valve 56 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the sixth throttle valve 56 is connected to the battery pack heat exchanger 70. At this time, the battery pack heat exchanger 70 acts as an evaporator.

[0154] In the eleventh branch, the first off-board heat exchanger 131 is connected to the third throttle valve 54. The refrigerant is throttled and cooled by the third throttle valve 54 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the third throttle valve 54 is connected to the refrigeration heat exchanger 222 of the refrigeration box 221. At this time, the refrigeration heat exchanger 222 acts as an evaporator to take away part of the heat in the refrigeration box 221; at the same time, the semiconductor refrigeration plate is turned on to dissipate the heat to the heating box 211 on the other side, so that the refrigeration system and the semiconductor refrigeration plate are synchronously and complementary to provide the refrigeration box 221 for refrigeration. The refrigerant at the outlet of the refrigeration heat exchanger 222 of the refrigeration box 221 is a low-temperature and low-pressure fluid; the refrigeration heat exchanger 222 of the refrigeration box 221 is connected to the gas-liquid separator 90 after merging with the outlet of the battery pack heat exchanger 70. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0155] In some embodiments, in combination Fig.14 , the thermal management system 100 has at least a battery pack cooling mode.

[0156] When the thermal management system 100 is in the battery pack cooling mode, the first on-off valve 41, the second on-off valve 42, the first one-way valve 62, the sixth throttle valve 56, the seventh throttle valve 57 and the fifth on-off valve 46 are turned on, the second throttle valve 51, the fourth throttle valve 52, the fifth throttle valve 53, the second on-off valve 42, the third on-off valve 43, the second one-way valve 61, the fourth on-off valve 44, the third throttle valve 54 and the first throttle valve 55 are turned off, the first external heat exchanger 131 acts as a condenser, and the battery pack heat exchanger 70 acts as an evaporator.

[0157] That is, when the thermal management system 100 cools the battery pack, the compressor 11 discharges high-temperature and high-pressure gas after compression, and the outlet of the compressor 11 is connected to the in-vehicle condenser 121. The in-vehicle heat exchanger only serves as a flow channel. At this time, the outlet of the in-vehicle condenser 121 is still high-temperature and high-pressure gas. The outlet of the in-vehicle condenser 121 is connected to the first external heat exchanger 131 through the second on-off valve 42. The refrigerant exchanges heat with the environment through the first external heat exchanger 131, and the refrigerant releases heat. The outlet of the first external heat exchanger 131 is a medium-temperature and high-pressure fluid. The first external heat exchanger 131 is connected to the sixth throttle valve 56 through the first one-way valve 62. The refrigerant is throttled and cooled by the sixth throttle valve 56, and becomes low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the sixth throttle valve 56 is connected to the battery pack heat exchanger 70. At this time, the battery pack heat exchanger 70 acts as an evaporator. The high-temperature fluid from the battery pack is cooled to a low-temperature fluid through the battery pack heat exchanger 70, and then provided to the battery pack for refrigeration. The refrigerant at the outlet of the battery pack heat exchanger 70 is a low-temperature and low-pressure fluid. The outlet of the battery pack heat exchanger 70 is connected to the gas-liquid separator 90, which separates the refrigerant and the refrigeration oil and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0158] In some embodiments, Fig.15 As shown, the thermal management system 100 has at least an air conditioning and battery pack synchronous heating mode.

[0159] When the thermal management system 100 is in the synchronous heating mode of the air conditioner and the battery pack, the sixth on-off valve 45, the second throttle valve 51, the third on-off valve 43, the fourth on-off valve 44, the seventh throttle valve 57, the sixth throttle valve 56 and the second one-way valve 61 are turned on, and the first on-off valve 41, the second on-off valve 42, the first one-way valve 62, the third throttle valve 54, the first throttle valve 55, the fourth throttle valve 52, the fifth throttle valve 53 and the fifth on-off valve 46 are turned off, the in-vehicle condenser 121 and the battery pack heat exchanger 70 act as condensers, and the second external heat exchanger 132 acts as an evaporator.

[0160] In the mode of synchronous heating of the air conditioner and the battery pack, the compressor 11 compresses and discharges high-temperature and high-pressure gas into two branches, including the twelfth branch and the thirteenth branch. In the twelfth branch, the compressor 11 is connected to the in-vehicle condenser 121, and the low-temperature air is heated to high-temperature air through the in-vehicle condenser 121 and provided to the vehicle for heating. The refrigerant is cooled to medium-temperature and high-pressure fluid through the in-vehicle condenser 121. The outlet of the in-vehicle condenser 121 is connected to the second throttle valve 51, and the refrigerant is throttled and cooled through the second throttle valve 51 to become low-temperature and low-pressure wet steam or supercooled liquid.

[0161] In the thirteenth branch, the compressed refrigerant enters the battery pack heat exchanger 70 through the sixth on-off valve 45 and the seventh throttle valve 57. The temperature of the low-temperature battery increases after heat exchange through the battery pack heat exchanger 70, and the refrigerant is cooled into a medium-temperature and high-pressure fluid through the battery pack heat exchanger 70. The outlet of the battery pack heat exchanger 70 is connected to the sixth throttle valve 56. The refrigerant is throttled and cooled through the sixth throttle valve 56 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the sixth throttle valve 56 is combined with the outlet of the second throttle valve 51, and is connected to the second off-vehicle heat exchanger 132 through the third on-off valve 43. At this time, the second off-vehicle heat exchanger 132 is an evaporator, and the refrigerant is heated by the ambient air or the residual heat of the motor cooling module 80 to complete the heat absorption process from the environment. The outlet refrigerant of the second off-vehicle heat exchanger 132 is a low-temperature and low-pressure fluid. The outlet of the second external heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and serves as an intermediate storage of the refrigerant gas to ensure the stable air intake of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0162] When the inlet temperature of the battery pack heat exchanger 70 exceeds a certain range, the local temperature of the batteries in the battery pack is likely to exceed its operating temperature range. Therefore, the required temperature of the in-vehicle condenser 121 needs to continue to increase (for example, the target temperature is 95°C). When the inlet temperature of the battery pack heat exchanger 70 reaches the upper limit (for example, the upper limit temperature is 65°C), the valve opening of the seventh throttle valve 57 is reduced to reduce the inlet temperature of the battery pack heat exchanger 70.

[0163] In some embodiments, reference Fig.16 The thermal management system 100 has at least a synchronous heating mode of the air conditioner, the battery pack and the heating unit.

[0164] When the thermal management system 100 is in the synchronous heating mode of the air conditioner, battery pack and heating unit, the heat exchange module 30 is turned on, the second throttle valve 51, the third on-off valve 43, the fourth on-off valve 44, the sixth on-off valve 45, the seventh throttle valve 57, the sixth throttle valve 56, the second one-way valve 61, the fourth throttle valve 52 and the fifth throttle valve 53 are turned on, the first on-off valve 41, the second on-off valve 42, the third throttle valve 54, the first throttle valve 55, the fifth on-off valve 46 and the first one-way valve 62 are turned off, the in-vehicle condenser 121, the outdoor heat exchanger, the battery pack heat exchanger 70 and the heating heat exchanger 212 act as condensers, and the second outdoor heat exchanger 132 acts as a heat exchanger.

[0165] When the thermal management system 100 is in the synchronous heating of the air conditioner, battery pack and heating unit, the compressor 11 compresses and discharges high-temperature and high-pressure gas into three branches, including the fourteenth branch, the fifteenth branch and the sixteenth branch. In the fourteenth branch, the outlet of the compressor 11 is connected to the in-vehicle condenser 121, and the low-temperature air is heated to high-temperature air through the in-vehicle condenser 121 and provided to the vehicle for heating. The refrigerant is cooled to medium-temperature and high-pressure fluid through the in-vehicle condenser 121. The outlet of the in-vehicle condenser 121 is connected to the second throttle valve 51, and the refrigerant is throttled and cooled through the second throttle valve 51 to become low-temperature and low-pressure wet steam or supercooled liquid.

[0166] In the fifteenth branch, the refrigerant at the outlet of the compressor 11 enters the battery pack heat exchanger 70 through the sixth on-off valve 45 and the seventh throttle valve 57. The temperature of the low-temperature battery increases after heat exchange through the battery pack heat exchanger 70, and the refrigerant is cooled into a medium-temperature and high-pressure fluid through the battery pack heat exchanger 70. The outlet of the battery pack heat exchanger 70 is connected to the sixth throttle valve 56. The refrigerant is throttled and cooled through the sixth throttle valve 56 to become low-temperature and low-pressure wet steam or supercooled liquid.

[0167] In the sixteenth branch, the outlet of the compressor 11 is connected to the fourth throttle valve 52, and the refrigerant enters the heating heat exchanger 212 through the fourth throttle valve 52. At this time, the heating heat exchanger 212 acts as a condenser, thereby providing heating to the vehicle-mounted heating box 211. When the heat pump system is insufficient in heating and needs to supplement heat, the semiconductor refrigeration plate can be turned on synchronously to supplement the heat in the heating box 211 and transport the cold to the refrigeration box 221. The outlet refrigerant of the heating heat exchanger 212 is a medium-temperature and high-pressure fluid. The outlet of the heating heat exchanger 212 is connected to the fifth throttle valve 53. The refrigerant is throttled and cooled by the fifth throttle valve 53 and becomes low-temperature and low-pressure wet steam or supercooled liquid. The outlets of the second throttle valve 51, the fifth throttle valve 53 and the sixth throttle valve 56 are combined and connected to the second off-vehicle heat exchanger 132 through the third on-off valve 43. At this time, the second off-vehicle heat exchanger 132 is an evaporator, and the refrigerant is heated by the ambient air or the residual heat of the motor cooling module 80 to complete the heat absorption process from the environment. The outlet refrigerant of the second off-vehicle heat exchanger 132 is a low-temperature and low-pressure fluid. The outlet of the second off-vehicle heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0168] When the inlet temperature of the battery pack heat exchanger 70 and the heating heat exchanger 212 exceeds a certain range, the local temperature in the power battery and the heating box 211 is likely to exceed its operating temperature range. Therefore, when the required temperature of the in-vehicle condenser 121 needs to continue to rise (for example, the target temperature is 95°C), and the inlet temperature of the battery pack heat exchanger 70 and the heating heat exchanger 212 reaches the upper limit (for example, the upper limit temperature is 65°C), the inlet temperature of the battery pack heat exchanger 70 and the heating heat exchanger 212 can be reduced by reducing the valve opening of the fourth throttle valve 52 and the seventh throttle valve 57. Among them, the fourth throttle valve 52 and the seventh throttle valve 57 realize the control of different heating temperatures when both are opened.

[0169] In some embodiments, in combination Fig.17 , the thermal management system 100 has at least a synchronous heating mode of the battery pack and the heating unit.

[0170] When the thermal management system 100 is in the synchronous heating mode of the battery pack and the heating unit, the heat exchange module 30 is turned on, the fourth throttle valve 52, the fifth throttle valve 53, the third on-off valve 43, the fourth on-off valve 44, the sixth on-off valve 45, the sixth throttle valve 56, the seventh throttle valve 57 and the second one-way valve 61 are turned on, the first on-off valve 41, the second throttle valve 51, the second on-off valve 42, the third throttle valve 54, the first throttle valve 55, the fifth on-off valve 46 and the first one-way valve 62 are turned off, the heating heat exchanger 212 and the battery pack heat exchanger 70 act as condensers, and the second external heat exchanger 132 acts as an evaporator.

[0171] In this embodiment, the high-temperature and high-pressure gas discharged by the compressor 11 after compression is divided into two branches, the two branches include the seventeenth branch and the eighteenth branch. In the seventeenth branch, the refrigerant at the outlet of the compressor 11 enters the battery pack heat exchanger 70 through the sixth on-off valve 45 and the seventh throttle valve 57. The temperature of the low-temperature battery increases after heat exchange through the battery pack heat exchanger 70, and the refrigerant is cooled into a medium-temperature and high-pressure fluid through the battery pack heat exchanger 70. The outlet of the battery pack heat exchanger 70 is connected to the sixth throttle valve 56. The refrigerant is throttled and cooled through the sixth throttle valve 56 to become low-temperature and low-pressure wet steam or supercooled liquid.

[0172] In the eighteenth branch, the refrigerant at the outlet of the compressor 11 enters the heating heat exchanger 212 through the fourth throttle valve 52. The outlet of the fourth throttle valve 52 is connected to the heating heat exchanger 212. At this time, the heating heat exchanger 212 acts as a condenser, thereby providing heating to the heating box 211. When the heating capacity of the heat pump system is insufficient and heat supplement is required, the semiconductor refrigeration plate can be turned on simultaneously to supplement the heat in the heating box 211 and transport the cold to the refrigeration box 221. The outlet refrigerant of the heating heat exchanger 212 is a medium-temperature and high-pressure fluid. The outlet of the heating heat exchanger 212 is connected to the fifth throttle valve 53. The refrigerant is throttled and cooled by the fifth throttle valve 53, and becomes low-temperature and low-pressure wet steam or supercooled liquid; the outlets of the fifth throttle valve 53 and the sixth throttle valve 56 are combined and connected to the second off-vehicle heat exchanger 132 through the third on-off valve 43. At this time, the second off-vehicle heat exchanger 132 is an evaporator. The refrigerant is heated by the ambient air or the residual heat of the motor cooling module 80, and the heat absorption process from the environment is completed. The outlet refrigerant of the second off-vehicle heat exchanger 132 is a low-temperature and low-pressure fluid. The outlet of the second off-vehicle heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and acts as an intermediate storage of the refrigerant gas to ensure the stable suction of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0173] In some embodiments, Fig.18 As shown, the thermal management system 100 has at least a battery pack heating mode.

[0174] When the thermal management system 100 is in the battery pack heating mode, the sixth on-off valve 45, the sixth throttle valve 56, the seventh throttle valve 57, the second one-way valve 61, the third on-off valve 43 and the fourth on-off valve 44 are turned on, the second throttle valve 51, the first on-off valve 41, the fourth throttle valve 52, the fifth throttle valve 53, the second on-off valve 42, the third throttle valve 54, the first throttle valve 55, the fifth on-off valve 46 and the first one-way valve 62 are turned off, the battery pack heat exchanger 70 acts as a condenser, and the second external heat exchanger 132 acts as an evaporator.

[0175] The compressor 11 discharges high-temperature and high-pressure gas after compression, and enters the battery pack heat exchanger 70 through the sixth on-off valve 45 and the seventh throttle valve 57. The temperature of the low-temperature battery increases after heat exchange through the battery pack heat exchanger 70, and the refrigerant is cooled into a medium-temperature and high-pressure fluid through the battery pack heat exchanger 70. The outlet of the battery pack heat exchanger 70 is connected to the sixth throttle valve 56. The refrigerant is throttled and cooled through the sixth throttle valve 56 to become low-temperature and low-pressure wet steam or supercooled liquid; the outlet of the battery pack heat exchanger 70 is connected to the second off-vehicle heat exchanger 132 through the third on-off valve 43. At this time, the second off-vehicle heat exchanger 132 is an evaporator, and the refrigerant is heated by the ambient air or the residual heat of the motor cooling module 80 to complete the heat absorption process from the environment. The outlet refrigerant of the second off-vehicle heat exchanger 132 is a low-temperature and low-pressure fluid. The outlet of the second external heat exchanger 132 is connected to the gas-liquid separator 90 through the fourth on-off valve 44. The gas-liquid separator 90 separates the refrigerant and the refrigeration oil and serves as an intermediate storage of the refrigerant gas to ensure the stable air intake of the compressor 11. Finally, the refrigerant returns to the compressor 11 to form a cycle.

[0176] In some embodiments, Figure 5 As shown, the thermal management system 100 also includes: a motor cooling module 80, the motor cooling module 80 includes: a three-way valve 82, a motor cooling channel 81, and a motor heat exchanger 83. The three-way valve 82 includes a first connection port, a second connection port, and a third connection port. The first end of the motor cooling channel 81 is connected to the first connection port; the first end of the motor heat exchanger 83 is connected to the second connection port; the first end of the second external heat exchanger 132 is connected to the third connection port, the second end of the motor heat exchanger 83 is connected to the first end of the second external heat exchanger 132, and the second end of the second external heat exchanger 132 is connected to the second end of the motor cooling channel 81; the motor heat exchanger 83 is opposite to the first external heat exchanger 131, and the second external heat exchanger 132 is connected between the third on-off valve 43 and the fourth on-off valve 44.

[0177] For example, in the air conditioning heating mode, the three-way valve 82 can be used to selectively connect the motor cooling channel 81 and the second vehicle exterior heat exchanger 132, so that the heat generated during the operation of the motor cooling module 80 flows through the motor cooling channel 81 to the second vehicle exterior heat exchanger 132 through the flow path, and performs heat exchange with the refrigerant flowing through the second vehicle exterior heat exchanger 132, so that the second vehicle exterior heat exchanger 132 can use the residual heat of the motor cooling module 80 to complete the process of absorbing heat from the environment, thereby improving efficiency. Optionally, the motor heat exchanger 83 is connected to the motor cooling channel 81 through the three-way valve 82, and the motor heat exchanger 83 is a radiator, which provides the first vehicle exterior heat exchanger 131 with the ambient temperature.
