DETAILED DESCRIPTION

[0034] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0035] A thermal management system 100 for a vehicle according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 11 .

[0036] According to the vehicle thermal management system 100 of the embodiment of the present application, the vehicle 1000 has a storage box 200 , and the thermal management system 100 includes: an air conditioning subsystem 300 and a heat exchange component 4 .

[0037] The air-conditioning subsystem 300 includes a compressor 1, and a heat exchange component 4 is suitable for adjusting the temperature inside the storage box 200. The heat exchange component 4 includes an energy storage component 41 and a first refrigerant branch 45. The first refrigerant branch 45 provides energy for the energy storage component 41. The energy storage component 41 is configured to store and release energy and is suitable for adjusting the temperature inside the storage box 200. The first refrigerant branch 45 is respectively connected to the air inlet 12 and the exhaust port 11 of the compressor 1.

[0038] Thus, the first refrigerant branch 45 can be integrated into the original thermal management system 100 of the vehicle 1000 to reuse the air-conditioning compressor 1, thereby directly controlling the temperature of the storage box 200 by using the original thermal management system 100, so that there is no need to set up additional temperature control structures such as a compressor for the storage box 200, which is convenient for reducing the number of components and making its structural size smaller, and having lower requirements for the layout space of the entire vehicle. At the same time, the first refrigerant branch 45 provides energy to the energy storage component 41, so that the energy storage component 41 can recover and store the coldness of the first refrigerant branch 45, so that when the compressor 1 is not working, the energy storage component 41 can be used to release the stored energy to keep the storage box 200 warm, thereby reducing the frequent start-up of the compressor 1, and is beneficial to reducing the energy consumption of the entire vehicle and improving the cruising range of the entire vehicle.

[0039] For example, a vehicle 1000 includes a storage box 200 and a thermal management system 100. It should be noted that the storage box 200 may be configured as a storage box 200 of an onboard refrigerator (i.e., an in-vehicle refrigerator system), and the storage box 200 is used to store food or drinks, etc. The heat exchange assembly 4 regulates the temperature within the storage box 200 to keep the food in the storage box 200 fresh.

[0040] For example, the thermal management system 100 includes: an air-conditioning subsystem 300 and a heat exchange component 4. The air-conditioning subsystem 300 includes a compressor 1, which is arranged on a refrigerant circulation loop 302. A first condenser 21, a first in-vehicle heat exchanger 31 and a heat exchange component 4 are also arranged on the refrigerant circulation loop 302.

[0041] For example, as shown in Figure 1, the compressor 1 has an exhaust port 11 and an air inlet 12, the first end of the first condenser 21 is connected to the exhaust port 11, one end of the first in-vehicle heat exchanger 31 is connected to the second end of the first condenser 21 through a first throttling element 51, and the other end of the first in-vehicle heat exchanger 31 is connected to the air inlet 12, and the heat exchange component 4 is suitable for regulating the temperature in the storage box 200, and the heat exchange component 4 includes an energy storage component 41, and the energy storage component 41 includes an energy storage component 41 and a first refrigerant branch 45. The first refrigerant branch 45 is respectively connected to the air inlet 12 and the exhaust port 11 of the compressor 1, so that the refrigerant discharged from the exhaust port 11 of the compressor 1 can flow through the first refrigerant branch 45 to achieve the temperature regulation of the storage box 200, and the energy storage component 41 is configured to store energy and is suitable for regulating the temperature in the storage box 200, and the first refrigerant branch 45 exchanges heat with the energy storage component 41 to achieve the first refrigerant branch 45 providing energy to the energy storage component 41.

[0042] The first condenser 21 can be configured as an external condenser, the first internal heat exchanger 31 can be configured as an evaporator, and the first throttling element 51 and the on-off valve 52 can both be configured as a two-way electronic expansion valve 18.

[0043] For example, the compressor 1 is constructed as a heat pump electric compressor. Compared with ordinary electric compressors, the heat pump electric compressor is designed to have increased durability to meet the life requirements of the system. The first in-vehicle heat exchanger 31 can be used to exchange heat with the passenger compartment in the vehicle, or the motor, or the battery, etc. Preferably, the first in-vehicle heat exchanger 31 can be used to exchange heat with the passenger compartment in the vehicle.

[0044] During actual use, the compressor 1 discharges the refrigerant from the exhaust port 11. The refrigerant passes through the first condenser 21, the first throttling element 51, and the first in-vehicle heat exchanger 31 in sequence, and flows back to the compressor 1 from the air inlet 12. At this time, the first in-vehicle heat exchanger 31 exchanges heat with the passenger compartment of the vehicle door. In this way, the air-conditioning subsystem 300 can realize heating or cooling of the passenger compartment in the vehicle, that is, the adjustment of the temperature in the cabin is realized.

[0045] Furthermore, as shown in Figure 5, the heat exchange component 4 includes an energy storage component 41, and the energy storage component 41 includes an energy storage component 41 and a first refrigerant branch 45. The first refrigerant branch 45 exchanges heat with the energy storage component 41, and the first refrigerant branch is respectively connected to the air inlet 12 and the exhaust port 11 of the compressor 1, so that the first refrigerant branch 45 and the first branch 301 can share the compressor 1.

[0046] For example, as shown in FIG1 , heat exchange assembly 4 is disposed outside storage box 200 to reduce the space occupied within storage box 200. Heat exchange assembly 4 also includes a fan 44, which is disposed corresponding to vent 201 of storage box 200. Fan 44 rotates to blow heat or cold from heat exchange assembly 4 through vent 201 into storage box 200, thereby controlling the temperature within storage box 200. Alternatively, heat exchange assembly 4 may be disposed directly within storage box 200, which is not limited herein.

[0047] Thus, while the air conditioning subsystem 300 adjusts the cabin temperature, the refrigerant discharged from the compressor 1 can flow to the first refrigerant branch 45 to heat or cool the storage box 200, that is, to adjust the temperature of the storage box 200, and the energy storage component 41 can exchange heat with the first refrigerant branch 45 to store energy. In this way, when the air conditioning subsystem 300 is not operating (that is, the compressor 1 is not operating), the energy of the energy storage component 41 is used to keep the storage box 200 warm. Insulation includes cooling insulation and heating insulation, etc., which are not limited here.

[0048] At the same time, the energy storage component 41 can store the coldness of the first refrigerant branch 45 and be used to adjust the temperature inside the storage box 200 when the compressor 1 is not working, so as to keep the food in the storage box 200 warm. That is, the energy storage component 41 can recycle the coldness of the first refrigerant branch 45 to reduce energy waste.

[0049] For example, the energy storage component 41 can be constructed as a phase-changing material, and a refrigerant evaporator can be installed in the energy storage component 41. The first refrigerant branch 45 is arranged in the refrigerant evaporator. The phase-changing material can absorb the energy of the low-temperature refrigerant flowing through the refrigerant evaporator and store the energy to realize the energy recovery of the first refrigerant branch 45 by the energy storage component 41.

[0050] Of course, the energy storage member 41 may also be constructed as other energy storage structures, which is not limited here.

[0051] In this way, the energy storage component 41 can be used to recycle the energy of the first refrigerant branch 45, thereby reducing the energy consumption of the entire vehicle and improving the cruising range of the entire vehicle.

[0052] It should be noted that in the related art, the heat exchange component 4 of the storage box 200 of the car refrigerator requires a set of heat exchange components 4 independent of the air-conditioning subsystem 300, that is, its heat exchange component 4 has no connection with the air-conditioning subsystem 300, and its heat exchange component 4 needs to be continuously powered to maintain the temperature of the storage box 200.

[0053] In the present application, an energy storage component 41 is provided to directly cool the storage box 200 by utilizing the original thermal management system 100 of the vehicle 1000, and the energy storage component 41 can recycle the energy of the first refrigerant branch 45, thereby reducing the energy consumption of the entire vehicle and facilitating the improvement of the vehicle's cruising range.

[0054] According to the thermal management system 100 of the vehicle in the embodiment of the present application, an energy storage component 41 is provided, and the first refrigerant branch 45 is connected to the first branch 301 to integrate the first refrigerant branch 45 into the original thermal management system 100 of the vehicle 1000, so that the temperature of the storage box 200 can be directly controlled by utilizing the original thermal management system 100, so that there is no need to separately provide a temperature control structure such as a compressor 1 for the storage box 200, which is convenient for reducing the number of components and making its structural size smaller, and having lower requirements for the layout space of the entire vehicle. At the same time, the energy storage component 41 can recover and store the energy of the first refrigerant branch 45, so that when the compressor 1 is not working, the energy stored in the energy storage component 41 can be used to keep the storage box 200 warm, so that there is no need to frequently start the compressor 1, which is beneficial to reducing the energy consumption of the entire vehicle and improving the cruising range of the entire vehicle.

[0055] In some embodiments, the first refrigerant branch 45 adjusts the temperature inside the storage box 200 , or the energy storage component 41 releases energy to adjust the temperature inside the storage box 200 .

[0056] For example, the first refrigerant branch 45 adjusts the temperature inside the storage box 200. At this time, the heat exchange component 4 can be in the first temperature adjustment mode. The first refrigerant branch 45 is respectively connected to the air inlet 12 and the exhaust port 11 of the compressor 1, so that the first refrigerant branch 45 and the first branch 301 can share the compressor 1. At the same time, the first refrigerant branch 45 can provide energy to the energy storage component 41 so that the energy storage component 41 stores energy.

[0057] In this way, the temperature of the storage box 200 can be adjusted through the first refrigerant branch 45, so that the first refrigerant branch 45 can be integrated into the original thermal management system 100 of the vehicle 1000, so that the storage box 200 can be directly cooled by using the original thermal management system 100, and there is no need to set up a temperature control structure such as a compressor 1 for the storage box 200 separately, which is convenient for reducing the number of components and making its structural size smaller, and having a lower demand on the layout space of the entire vehicle.

[0058] When the energy storage component 41 releases energy to adjust the temperature inside the storage box 200, the heat exchange component 4 can be in the second temperature control mode. At this time, the energy storage component 41 releases energy (cold or heat) to adjust the temperature inside the storage box 200. In this way, the energy storage component 41 can use the energy stored in the energy storage component 41 to keep the storage box 200 warm when the compressor 1 is not working, thereby reducing the frequent starting of the compressor 1, and is beneficial to reducing the energy consumption of the entire vehicle and improving the cruising range of the entire vehicle.

[0059] It should be noted that, when the heat exchange component 4 is in the second temperature adjustment mode, the heat exchange component 4 can be provided with a cooling and heat preservation mode and a heating and heat preservation mode.

[0060] For example, in the cooling and heat preservation mode, the first end of the first refrigerant branch 45 is connected to the second end of the first condenser 21 through the on-off valve 52 , and the second end of the first refrigerant branch 45 is connected to the air inlet 12 .

[0061] In this way, the compressor 1, the first condenser 21 and the heat exchange component 4 form a loop. At this time, the compressor 1 discharges the refrigerant from the exhaust port 11. The refrigerant passes through the first condenser 21, the on-off valve 52, and the first refrigerant branch 45 in sequence, and flows back to the compressor 1 from the air inlet 12. At this time, the temperature of the refrigerant after passing through the first condenser 21 is relatively low. The first refrigerant branch 45 exchanges heat with the energy storage component 41, so that the energy storage component 41 obtains the coldness of the first refrigerant branch 45 and realizes refrigeration in the storage box 200, thereby realizing the preservation of food.

[0062] The first throttling element 51 and the on-off valve 52 may both be constructed as solenoid valves 15 to ensure that the flow of the refrigerant in the flow path can be controlled.

[0063] Thus, the first refrigerant branch 45 can be integrated into the original thermal management system 100 of the vehicle 1000, that is, the heat exchange component 4 can be integrated into the original thermal management system 100 of the vehicle 1000, so that the original thermal management system 100 can be used to directly realize the cooling of the storage box 200, so that there is no need to set up a temperature control structure such as a compressor 1 for the storage box 200 separately, which is convenient for reducing the number of components and making its structural size smaller, and the space requirement for the entire vehicle layout is low.

[0064] For example, in the heating and keeping warm mode, as shown in FIG1 , the thermal management system 100 of the vehicle further includes a heat pump plate exchanger 22 .

[0065] As shown in Figure 1, the first end of the heat pump plate exchanger 22 (the right end of the heat pump plate exchanger 22 as shown in Figure 1) is connected to the air inlet 12; as shown in Figure 6, in the heating and insulation mode, the second end of the first refrigerant branch 45 is connected to the exhaust port 11, and the first end of the first refrigerant branch 45 is connected to the second end of the heat pump plate exchanger 22 (the left end of the heat pump plate exchanger 22 as shown in Figure 1) through the on-off valve 52.

[0066] Therefore, the first refrigerant branch 45 can be integrated into the original thermal management system 100 of the vehicle 1000, so that the original thermal management system 100 can be used to directly heat the storage box 200, so that there is no need to set up a temperature control structure such as a compressor 1 for the storage box 200 separately, which is convenient for reducing the number of components and making its structural size smaller, and the space requirement for the entire vehicle layout is low. At the same time, the energy storage component 41 can recover and store the heat of the first refrigerant branch 45, so that when the compressor 1 is not working, the energy stored in the energy storage component 41 can be used to keep the storage box 200 warm, thereby reducing the energy consumption of the entire vehicle and helping to improve the cruising range of the entire vehicle.

[0067] For example, the heat pump plate exchanger 22 can be used to exchange heat for the motor electronic control 91. At this time, in the heating and insulation mode, the second end of the first refrigerant branch 45 is connected to the exhaust port 11, and the first end of the first refrigerant branch 45 is connected to the second end of the heat pump plate exchanger 22 (the left end of the heat pump plate exchanger 22 as shown in Figure 1) through the on-off valve 52.

[0068] Since the first refrigerant branch 45 is located on the upstream side of the heat pump plate exchanger 22, the high-temperature and high-pressure refrigerant can directly flow into the first refrigerant branch 45, and through the heat exchange between the first refrigerant branch 45 and the energy storage component 41, the energy storage component 41 can obtain the heat of the refrigerant and heat the storage box 200 through the energy storage component 41.

[0069] At the same time, the energy storage component 41 can store the heat of the first refrigerant branch 45 and be used to adjust the temperature inside the storage box 200 when the compressor 1 is not working, so as to keep the food in the storage box 200 warm. That is, the energy storage component 41 can recycle the heat of the first refrigerant branch 45 to reduce energy waste.

[0070] In some embodiments, the heat exchange assembly 4 further includes a first heat exchanger 42 , and the first heat exchanger 42 is connected in series with the first refrigerant branch 45 .

[0071] The first heat exchanger 42 can be constructed as an evaporator. Thus, by setting a first refrigerant branch 45 and connecting it in series, when the refrigerant flows through the first refrigerant branch 45, heat exchange between the air in the storage box 200 and the refrigerant can be achieved through the first heat exchanger 42, thereby achieving temperature regulation of the storage box 200.

[0072] In some embodiments, the first refrigerant branch 45 passes through the energy storage component 41 .

[0073] Therefore, by setting the first refrigerant branch 45 to pass through the energy storage component 41, on the one hand, the first refrigerant branch 45 can be integrated into the energy storage component 41 to reduce the design of external pipelines, which is beneficial to improving the integrated design and reducing the volume. At the same time, it is convenient to use the energy storage component 41 to play a certain protective role on the first refrigerant branch 45. On the other hand, the contact area between the first refrigerant branch 45 and the energy storage component 41 can be increased to increase the heat exchange area between the two, so that the two can fully exchange heat to improve the heat exchange efficiency of the two, that is, to improve the efficiency of energy storage component 41 in storing energy.

[0074] In some embodiments, the air conditioning subsystem 300 includes a first branch 301 for adjusting the temperature in the cabin, and the first branch 301 and the first refrigerant branch 45 are connected in parallel.

[0075] Thus, by providing the first branch 301 and the first refrigerant branch 45 in parallel, the first refrigerant branch 45 can be designed independently, and the provision of the first refrigerant branch 45 does not affect other structures of the first branch 301, thereby reducing the difficulty of providing the first refrigerant branch 45. It should be noted that at least a portion of the refrigerant circulation circuit 302 is configured as the first branch 301.

[0076] In some embodiments, as shown in FIG1 , the first branch 301 is connected in series with a second heat exchanger 30 for adjusting the temperature in the cabin.

[0077] Therefore, by providing the second heat exchanger connected in series with the first branch 301, the temperature inside the cabin can be regulated.

[0078] For example, as shown in FIG1 , two second heat exchangers 30 may be provided, namely an evaporator 31 and a second condenser 32 . The evaporator 31 and the second condenser 32 may be arranged in parallel, wherein the evaporator 31 and the second condenser 32 may be used to cool and heat the vehicle 1000 , respectively. In this way, the cabin temperature can be adjusted by the second heat exchanger 30 .

[0079] In some embodiments, the air conditioning subsystem 300 includes a first branch 301 for adjusting the temperature in the cabin, and the first branch 301 and the first refrigerant branch 45 are connected in series.

[0080] As a result, the first refrigerant branch 45 can always be connected to the first branch 301, eliminating the need to separately control the on / off state of the first refrigerant branch 45. This allows the first refrigerant branch 45 to share control components with the first branch 301, thereby improving integration and reducing the number of components to lower costs. It should be noted that at least a portion of the refrigerant circulation loop 302 is configured as the first branch 301.

[0081] In some embodiments, the integrated thermal management system 100 further includes an on-off valve 52 for controlling the on-off of the first refrigerant branch 45 .

[0082] Therefore, by setting the on-off valve 52, the on-off state of the first refrigerant branch 45 can be controlled separately. For example, when the first refrigerant branch 45 needs to be used, the on-off valve 52 is controlled to open the first refrigerant branch 45 to achieve control of the temperature of the storage box 200, or when the storage box 200 is not needed, that is, when the first refrigerant branch 45 is not needed, the on-off valve 52 is controlled to disconnect the first refrigerant branch 45 to reduce energy waste and avoid the energy storage component 41 from continuously absorbing energy, thereby helping to extend the service life of the energy storage component 41.

[0083] The on-off valve 52 may be constructed as a throttling element, and the opening of the throttling element may be controlled to control the on-off of the first refrigerant branch 45 , or the on-off valve 52 may be constructed as a solenoid valve, etc., which is not limited here.

[0084] In some embodiments, as shown in Figure 1, the vehicle's thermal management system 100 also includes a first control valve 61 and a second control valve 62, the first control valve 61 is respectively connected to the exhaust port 11 and the first end of the first condenser 21, and the second control valve 62 is respectively connected to the exhaust port 11 and the second end of the first refrigerant branch 45.

[0085] Therefore, by setting a first control valve 61 between the exhaust port 11 and the first end of the first condenser 21, and setting a second control valve 62 between the exhaust port 11 and the second end of the first refrigerant branch 45, it is convenient to open the first control valve 61 to achieve the cooling and insulation mode, or open the second control valve 62 to achieve the heating and insulation mode.

[0086] In other words, by providing the first control valve 61 and the second control valve 62 , the thermal management system 100 can be switched between the cooling and heat preservation mode and the heating and heat preservation mode, thereby avoiding interference between the flow paths in the two modes.

[0087] In some embodiments, as shown in Figure 1, the vehicle's thermal management system 100 also includes a second in-vehicle heat exchanger 32. The thermal management system 100 includes a heating mode. In the heating mode, the first end of the second in-vehicle heat exchanger 32 (the left end of the second in-vehicle heat exchanger 32 as shown in Figure 1) is connected to the exhaust port 11 and the second end of the second in-vehicle heat exchanger 32 (the right end of the second in-vehicle heat exchanger 32 as shown in Figure 1) is connected to the second end of the heat pump plate exchanger 22 through the third throttling element 53.

[0088] As a result, the compressor 1, the second in-vehicle heat exchanger 32, and the heat pump plate exchanger 22 form a heating circuit, and the second in-vehicle heat exchanger 32 is correspondingly provided with an air PTC 20. In the heating mode, when the refrigerant flows through the first in-vehicle heat exchanger 31, the air PTC 20 can blow the heat of the second in-vehicle heat exchanger 32 into the passenger compartment to achieve heating of the passenger compartment.

[0089] In some embodiments, as shown in FIG. 1 , the heat exchange assembly 4 further includes a first heat exchanger 42 , and the first heat exchanger 42 is connected in series with the first refrigerant branch 45 .

[0090] Therefore, by providing the first heat exchanger 42 , heat is exchanged between the storage box 200 and the first refrigerant branch 45 through the first heat exchanger 42 , and the temperature of the storage box 200 is controlled by utilizing the existing in-vehicle thermal management system 100 .

[0091] In some embodiments, as shown in FIG. 1 , the thermal management system 100 of the vehicle further includes a sterilization module 43 for sterilizing the heat exchange component 4 .

[0092] Therefore, by providing a sterilization module 43 , the heat exchange component 4 can be sterilized to prevent bacteria from growing on the surface of the heat exchange component 4 and causing mold and odor, thereby affecting food safety.

[0093] For example, in order to ensure the freshness of the food in the storage box 200 , a sterilization module 43 is arranged in the storage box 200 so that the sterilization module 43 can simultaneously disinfect the storage box 200 and the heat exchange component 4 .

[0094] Exemplarily, the sterilization module 43 is configured as an ultraviolet sterilization lamp, which is located outside the storage box 200 and is suitable for irradiating along the vent 201 toward the inside of the storage box 200 for sterilization and disinfection.

[0095] It should be noted that the structure of the ultraviolet sterilization lamp is simpler, more environmentally friendly, and has a better sterilization effect. In this way, while ensuring the sterilization effect, the freshness of the food in the storage box 200 can be guaranteed. For example, an ultraviolet sterilization lamp is arranged in the storage box 200 so that the sterilization module 43 can disinfect and sterilize the storage box 200 and the heat exchange component 4 at the same time.

[0096] In some embodiments, the energy storage element 41 is constructed of a phase change material, so that the energy storage element 41 can better absorb or release the energy of the first refrigerant branch 45 .

[0097] Of course, in some other embodiments, the energy storage member 41 may also be constructed as other structures capable of absorbing or releasing energy.

[0098] In some embodiments, as shown in FIG1 , the thermal management system 100 further includes a gas-liquid separator 7 .

[0099] The gas-liquid separator 7 is provided with a heating device for heating the refrigerant. The outlet of the gas-liquid separator 7 is connected to the air inlet 12 , and the inlet of the gas-liquid separator 7 is connected to the other end of the first in-vehicle heat exchanger 31 .

[0100] Therefore, by setting up the gas-liquid separator 7, in order to avoid the influence of liquid hammer of the system liquid refrigerant on the compressor 1 in winter, the air outlet of the gas-liquid separator 7 is connected to the air inlet 12, that is, the gas-liquid separator 7 is set upstream of the air inlet 12 of the compressor 1. In this way, by setting up the gas-liquid separator 7 with a heating device upstream of the air inlet 12 of the compressor 1, the refrigerant can be heated, so that the liquid refrigerant that has not been vaporized can be vaporized by direct heating or coaxial tube heat radiation, thereby avoiding the compressor 1 being hit by the liquid refrigerant.

[0101] The heating device may be a heating wire or a coaxial tube heat radiation structure, which is not limited here.

[0102] In some embodiments, as shown in FIG. 1 , the thermal management system 100 of the vehicle further includes a first heat exchange element 8 for performing heat exchange with the battery pack. The first heat exchange element 8 is connected in parallel with the heat exchange assembly 4 .

[0103] Therefore, by setting the first heat exchanger 8, the battery thermal management module 8a is integrated into the thermal management system 100, so as to utilize part of the structure in the thermal management system 100 to realize the thermal management of the battery, and since the first heat exchanger 8 is connected in parallel with the heat exchange component 4, the difficulty of arranging the first heat exchanger 8 is reduced, and it is beneficial to reduce the mutual influence between the battery thermal management module 8a and the heat exchange component 4.

[0104] For example, the first heat exchange component 8 can be constructed as a battery pack cold plate, which is integrated inside the battery pack and is used to heat or cool the battery pack. In this way, the battery pack cold plate can be integrated into the thermal management system 100, so that the battery pack cold plate can utilize structures such as the compressor 1 in the thermal management system 100 to achieve heat exchange with the battery.

[0105] In some embodiments, as shown in FIG1 , there are multiple first heat exchange elements 8 , and the multiple first heat exchange elements 8 are connected in parallel.

[0106] Therefore, by providing a plurality of first heat exchange elements 8 connected in parallel, the difficulty of providing the plurality of first heat exchange elements 8 is reduced, and heat exchange of a plurality of batteries is facilitated.

[0107] A thermal management system 100 according to an embodiment of the present application will be described below with reference to FIG. 1-10 .

[0108] As shown in Figure 1, the thermal management system 100 includes a compressor 1, a first condenser 21, a heat pump plate exchanger 22, a first in-vehicle heat exchanger 31, a second in-vehicle heat exchanger 32, a high-pressure sensor 13, a temperature sensor 14, a solenoid valve 15, a pressure and temperature sensor 16, a one-way valve 17, an electronic expansion valve 18, a liquid storage drying tank 19, an air PTC 20, a first throttling element 51, an on-off valve 52, a third throttling element 53, a first control valve 61, a second control valve 62, a gas-liquid separator 7, a heat exchange component 4, a battery thermal management module 8a and a battery electronic control coolant circuit.

[0109] As shown in FIG1 , the heat exchange component 4 , the battery thermal management module 8 a and the battery electronic control coolant circuit are all integrated into the thermal management system 100 , and the heat exchange component 4 is connected in series between the first condenser 21 and the compressor 1 .

[0110] As shown in FIG2 , the heat exchange assembly 4 includes an energy storage component 41 , a first heat exchanger 42 , a fan 44 and a sterilization module 43 .

[0111] Battery thermal management module 8a is arranged in parallel with heat exchange assembly 4. As shown in Figure 3, battery thermal management module 8a includes: first heat exchange element 8, large-diameter throttle valve 8, temperature sensor 14, pressure and temperature sensor 16, and electronic expansion valve 18. When multiple battery pack cold plates are connected in parallel, multiple battery thermal management modules 8a can be arranged in parallel.

[0112] The battery electronic control coolant circuit is connected in parallel with the heat pump plate exchanger 22, and as shown in Figure 4, the battery electronic control coolant circuit includes: motor electronic control 91, water pump 92, water temperature sensor 93, four-way water valve 94, valve port a, valve port b, valve port c, valve port d, radiator 95, electronic fan 96 and coolant kettle 97.

[0113] The battery electronically controlled coolant circuit has at least five circuit operating conditions:

[0114] Coolant circuit operating condition 1: Coolant flows from motor electronic control 91 → water pump 92 → water temperature sensor 93 → heat pump plate exchanger 22 → valve port a of four-way water valve 94 → valve port d of four-way water valve 94 → motor electronic control 91. The principle of this circuit is that under certain low-temperature conditions, when the refrigerant side requires waste heat from the coolant circuit and the motor electronic control 91 does not require heat dissipation from radiator 95, the high-temperature coolant flowing through the heat pump plate exchanger 22 exchanges heat with the low-temperature refrigerant flowing through the heat pump plate exchanger 22. This heat exchange function of the heat pump plate exchanger 22 transfers heat from the coolant side to the refrigerant side, effectively utilizing the waste heat generated by the motor electronic control 91. This reduces low-temperature energy consumption and improves driving range.

[0115] Coolant circuit operating condition two: the coolant flows from the motor electronic control 91 → water pump 92 → water temperature sensor 93 → heat pump plate changer 22 → valve port a of the four-way water valve 94 → valve port c of the four-way water valve 94 → radiator 95 → motor electronic control 91; at the same time, the coolant flows from the motor electronic control 91 → water pump 92 → water temperature sensor 93 → heat pump plate changer 22 → valve port a of the four-way water valve 94 → valve port d of the four-way water valve 94 → motor electronic control 91. The principle of this circuit is that under a certain low-temperature environment, the refrigerant side has a demand for waste heat utilization in the coolant circuit, and the waste heat generated by the motor electronic control 91 needs to be dissipated by the radiator 95, and the waste heat utilization demand is higher than the heat dissipation demand, the coolant enters through the valve port a of the four-way water valve 94, and at the same time, the valve port d of the four-way water valve 94 and the valve port c of the four-way valve go out, and finally passes through the circulation loop to exchange heat with the low-temperature refrigerant flowing through the heat pump plate exchanger 22. In this way, through the heat exchange effect of the heat pump plate exchanger 22, the heat on the coolant side is exchanged to the refrigerant side, and the waste heat is effectively utilized, thereby reducing low-temperature energy consumption, while meeting the heat dissipation demand of the motor electronic control 91, and the excess heat is dissipated to the external environment through the radiator 95.

[0116] Coolant circuit working condition three: coolant flows from motor electronic control 91 → water pump 92 → water temperature sensor 93 → heat pump plate exchanger 22 → valve port a of four-way water valve 94 → valve port c of four-way water valve 94 → radiator 95 → motor electronic control 91.

[0117] The principle of this circuit is that, under certain low-temperature conditions, the refrigerant side has a need to utilize waste heat from the coolant circuit, while the motor and electronic control 91 also has a need to dissipate heat, and the need to dissipate waste heat from the motor and electronic control 91 is greater than the need to dissipate waste heat. Through the heat exchange function of the heat pump plate exchanger 22, heat from the coolant side is transferred to the refrigerant side, effectively utilizing the waste heat and thus reducing low-temperature energy consumption. At the same time, the motor and electronic control 91's need to dissipate heat is met, and excess heat is dissipated to the outside environment through the radiator 95.

[0118] Coolant circuit operating condition four: coolant flows from motor electronic control 91 → water pump 92 → water temperature sensor 93 → heat pump plate exchanger 22 → valve port a of four-way water valve 94 → valve port c of four-way water valve 94 → radiator 95 → motor electronic control 91.

[0119] The principle of this circuit is that under a certain low-temperature environment, the refrigerant side has a demand for waste heat utilization in the coolant working circuit, and at the same time, the heat generated by the motor electronic control 91 is insufficient, that is, when the temperature of the coolant working condition in the motor electronic control 91 is lower than the external ambient temperature, the coolant needs to absorb heat from the environment outside the vehicle through the radiator 95, and then pass through the circulation loop to exchange heat with the low-temperature refrigerant flowing through the heat pump plate exchanger 22. In this way, through the heat exchange effect of the heat pump plate exchanger 22, the heat on the coolant side is transferred to the refrigerant side, and the heat from the external environment and the heat generated by the motor electronic control 91 are effectively utilized, thereby reducing low-temperature energy consumption and improving driving range.

[0120] Coolant circuit operating condition five: coolant flows from the motor electronic control 91 → water pump 92 → valve port b of the four-way water valve 94 → valve port c of the four-way water valve 94 → radiator 95 → motor electronic control 91.

[0121] The principle of this circuit is that under a certain high temperature environment, the refrigerant side has no demand for waste heat utilization in the coolant working circuit. At this time, no matter whether the motor electronic control 91 has heat dissipation demand and how much the heat dissipation demand is, the four-way water valve 94 short-circuits the heat pump plate exchanger 22, and the coolant working circuit does not flow through the heat pump plate exchanger 22 but directly flows through the radiator 95, quickly dissipating the heat of the motor electronic control 91, and the heat is dissipated to the external environment through the radiator 95.

[0122] The thermal management system 100 in this embodiment can have multiple modes, and the various working conditions include: cooling and insulation mode (only the storage box 200 is cooled and insulated), heating and insulation mode (only the storage box 200 is heated and insulated), passenger compartment cooling mode only, passenger compartment heating mode only, battery cooling mode only, battery heating mode only and other modes.

[0123] As shown in Figure 5, in cooling and heat preservation mode (only the storage box 200 is cooled and heat-insulated): the refrigerant circuit: the refrigerant flows from compressor 1 → pressure sensor → temperature sensor 14 → solenoid valve 15 → first condenser 21 → liquid storage tank 19 → check valve 17 → electronic expansion valve 18 → temperature sensor 14 → energy storage element 41 → first heat exchanger 42 → pressure and temperature sensor 16 → solenoid valve 15 → check valve 17 → gas-liquid separator 7 → compressor 1. In this circulation loop, the high-temperature, high-pressure gaseous refrigerant produced by compressor 1 passes through the first condenser 21, exchanges heat with the cold air outside the vehicle, and becomes medium-temperature, medium-pressure liquid refrigerant. After the medium-temperature, medium-pressure refrigerant expands through the electronic expansion valve 18, it becomes low-temperature, low-pressure liquid refrigerant. The low-temperature liquid refrigerant flows through the energy storage element 41, where the cold energy is absorbed by the energy storage element 41, and then flows through the first heat exchanger 42, exchanging heat with the hot air in the heat exchange component 4, thereby cooling the heat exchange component 4. When the cooling capacity of the energy storage component 41 is full, the compressor 1 stops working and the cooling capacity is released through the energy storage component 41 . The fan 44 is turned on and the air flows, thereby meeting the cooling and heat preservation performance of the heat exchange component 4 .

[0124] As shown in Figure 6, heating and insulation mode (only the storage box 200 is heated and insulated): refrigerant circuit: refrigerant from compressor 1 → pressure sensor → temperature sensor 14 → solenoid valve 15 → first heat exchanger 42 → energy storage component 41 → temperature sensor 14 → electronic expansion valve 18 → one-way valve 17 → heat pump plate exchanger 22 → solenoid valve 15 → gas-liquid separator 7 → compressor 1.

[0125] In this circulation loop, the high-temperature and high-pressure gaseous refrigerant generated by the compressor 1 flows through the first heat exchanger 42, exchanges heat with the cold air in the storage box 200, and heats the storage box 200. The high-temperature gaseous refrigerant then flows through the energy storage component 41, and the energy storage component 41 absorbs excess heat. When the energy storage component 41 has completed energy storage, the compressor 1 can stop working, and the energy storage component 41 provides a heat source for insulation.

[0126] As shown in Figure 7, in the passenger compartment cooling mode only: refrigerant circuit: refrigerant from compressor 1 → pressure sensor → temperature sensor 14 → solenoid valve 15 → first condenser 21 → liquid storage dryer 19 → one-way valve 17 → electronic expansion valve 18 → first in-vehicle heat exchanger 31 → pressure and temperature sensor 16 → gas-liquid separator 7 → compressor 1.

[0127] In this circulation loop, the high-temperature, high-pressure gaseous refrigerant generated by compressor 1 passes through first condenser 21, undergoes heat exchange with the cold air outside the vehicle, and is converted into medium-temperature, medium-pressure liquid refrigerant. After expansion through electronic expansion valve 18, the medium-temperature, medium-pressure liquid refrigerant is converted into low-temperature, low-pressure liquid refrigerant. The low-temperature liquid refrigerant then flows through first in-vehicle heat exchanger 31, exchanging heat with the hot air inside the passenger compartment, thereby cooling the passenger compartment.

[0128] As shown in Figure 8, in the passenger compartment heating mode only: refrigerant circuit: refrigerant from compressor 1 → pressure sensor → temperature sensor 14 → second in-vehicle heat exchanger 32 (synchronously, it is turned on when there is a demand for wind PTC 20 to turn on) → electronic expansion valve 18 → heat pump plate exchanger 22 → solenoid valve 15 → gas-liquid separator 7 → compressor 1.

[0129] In this circulation loop, the high-temperature and high-pressure gaseous refrigerant generated by the compressor 1 flows through the storage box evaporator, exchanges heat with the cold air in the storage box, and heats the storage box 200; the high-temperature gaseous refrigerant passes through the second in-vehicle heat exchanger 32, exchanges heat with the cold air in the passenger compartment, and heats the passenger compartment.

[0130] As shown in Figure 9, in battery cooling mode only: refrigerant circuit: refrigerant from compressor 1 → pressure sensor → temperature sensor 14 → solenoid valve 15 → first condenser 21 → liquid storage drying tank 19 → one-way valve 17 → electronic expansion valve 18 → temperature sensor 14 → first heat exchanger 8 → pressure and temperature sensor 16 → large-diameter throttle valve 8 → solenoid valve 15 → one-way valve 17 → gas-liquid separator 7 → compressor 1.

[0131] As shown in Figure 10, battery heating mode only: refrigerant circuit: refrigerant from compressor 1 → pressure sensor → temperature sensor 14 → solenoid valve 15 → large-diameter throttle valve 8 → pressure and temperature sensor 16 → first heat exchanger 8 → temperature sensor 14 → electronic expansion valve 18 → one-way valve 17 → heat pump plate exchanger 22 → solenoid valve 15 → gas-liquid separator 7 → compressor 1.

[0132] In this circulation loop, the high-temperature and high-pressure gaseous refrigerant generated by the compressor 1 flows through the first heat exchanger 8. The refrigerant passes through the battery pack cold plate and exchanges heat with the low-temperature battery pack, thereby heating the battery pack.

[0133] Other modes: (1) Any two or more of the above six modes can be used in combination; (2) Cooling and heat preservation mode (only the storage box 200 is cooled and heat-insulated), passenger compartment cooling mode only, battery cooling mode only and the above coolant circuit working condition five can be used in combination.

[0134] (3) Heating and insulation mode (storage box 200 heating + insulation only), passenger compartment heating mode only, battery heating mode only are used in combination with the above-mentioned coolant circuit operating conditions 1, 2, 3 and 4.

[0135] It should be noted that: in all the above embodiments, in the circuit through which the refrigerant flows, all valves are open; in the circuit through which the refrigerant does not flow, the valves on the circuit are closed.

[0136] Therefore, the thermal management system 100 in this embodiment has at least the following advantages compared with related technologies:

[0137] 1. In the related art, the cooling system and heating system of the heat exchange component 4 are independent systems; however, in this embodiment, the cooling system and heating system of the heat exchange component 4 (storage box 200) share the vehicle thermal management system 100, and the vehicle heat pump compressor 1 is used to directly cool and heat the heat exchange component 4.

[0138] 2. The heat exchange component 4 is integrated into the thermal management system 100, which can reduce the cost of the entire vehicle, save vehicle space, and reduce NVH and vibration problems. In addition, in low temperature environments, the heat pump system can be used for heating, which can effectively save energy.

[0139] 3. In the related art, the insulation work after cooling or heating only uses the foam layer for insulation, and the insulation effect is relatively poor. However, in this embodiment, the heat exchange component 4 is increased with an energy storage component 41. When the compressor 1 is not working, the energy storage component 41 can keep the storage box 200 warm for a long time.

[0140] 4. In the related art, the insulation work after cooling or heating only uses the foam layer for insulation, and the insulation effect is relatively poor; in the patented technology, the heat exchange component 4 adds an energy storage part 41, and when the compressor 1 is working, it starts to store energy. After the energy is fully charged, the compressor 1 can be disconnected and the heat can be kept for a long time; thus, it is not affected by the disconnection of the compressor 1.

[0141] 5. In the related art, since the outlet pressure of the heat exchange component 4 may be extremely low, such as as low as below 0.18 MPa, in order to prevent the compressor 1 from being damaged by liquid hammer, a gas-liquid separator 7 with a heating device is arranged at the suction port of the compressor 1. Its function is to vaporize the liquid refrigerant in the unvaporized state by direct heating or coaxial tube heat radiation, thereby preventing the compressor 1 from being liquid hammered by the liquid refrigerant.

[0142] 6. In the related art, since the temperature control system includes an energy storage component 41 and an evaporator, in order to prevent bacteria from growing on the surfaces of the two components and causing mold and odor, thereby affecting food safety, and to ensure the freshness of the food in the storage box 200, an ultraviolet sterilization lamp is arranged in the heat exchange component 4, and the storage box 200, the first heat exchanger 42, and the energy storage component 41 are disinfected and sterilized at the same time.

[0143] Of course, the above description of the partial structure of the thermal management system 100 is only used as an example of a preferred embodiment and does not represent a limitation thereto.

[0144] The present application also discloses a vehicle 1000 .

At the same time, the energy storage component 41 can recover and store the energy of the first refrigerant branch 45, so that when the compressor 1 is not working, the energy stored in the energy storage component 41 can be used to keep the storage box 200 warm, thereby reducing the energy consumption of the entire vehicle and facilitating the improvement of the cruising range of the entire vehicle.
