Abstract
Description
A vehicle thermal management system and vehicle Technical Field
[0001] This application relates to the field of vehicle thermal management system technology, and more particularly to a vehicle thermal management system and a vehicle. Background Technology
[0002] To enhance the user experience, more and more car models are being equipped with in-car refrigerators to keep food and drinks fresh or chilled.
[0003] Currently, in-vehicle refrigerators have issues such as heat release into the passenger compartment leading to increased temperature and noise, which affect passenger comfort.
[0004] Application content
[0005] This application provides a vehicle thermal management system and a vehicle, which aims to improve user ride comfort.
[0006] This application provides a vehicle thermal management system in a first aspect. The vehicle thermal management system includes a compressor, a condenser, a first flow regulator, and a passenger compartment evaporator. The outlet of the compressor is connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the first flow regulator, the outlet of the first flow regulator is connected to the inlet of the passenger compartment evaporator, and the outlet of the passenger compartment evaporator is connected to the inlet of the compressor.
[0007] The vehicle thermal management system further includes a second flow regulator and an on-board refrigerator. The on-board refrigerator includes at least one first storage compartment. The first storage compartment includes a first evaporator and a semiconductor refrigerator that are fitted together. The outlet of the condenser is also connected to the inlet of the second flow regulator. The outlet of the second flow regulator is connected to the inlet of the first evaporator. The outlet of the first evaporator is connected to the inlet of the compressor.
[0008] The semiconductor cooler has both cooling and heating functions. By changing the direction of the current flowing into the semiconductor cooler, the semiconductor cooler can be used to cool or heat, so that the first storage chamber can be used for cooling or heating.
[0009] In this embodiment, the compressor compresses the refrigerant into a high-temperature, high-pressure gas. The condenser is typically installed in front of the car radiator to dissipate the heat of the refrigerant into the air, cooling and condensing the refrigerant into a high-pressure liquid. The passenger compartment evaporator is usually located in the vehicle's ventilation ducts and is used to rapidly evaporate the refrigerant, absorbing heat from the vehicle interior to achieve cooling. The battery cooler introduces refrigerant to absorb heat from the coolant in the battery pack's cooling circuit, carrying away the heat from the coolant through heat exchange, thus cooling the battery pack.
[0010] This application embodiment integrates the vehicle refrigerator with a first storage compartment into the vehicle thermal management system, allowing the vehicle refrigerator to share the compressor and condenser in the vehicle thermal management system, thus solving the problems of heat load generated by the vehicle refrigerator being discharged into the passenger compartment and excessive noise.
[0011] In addition, the vehicle refrigerator changes the direction of the current flowing into the semiconductor refrigerator so that the cooling end or heating end of the semiconductor refrigerator comes into contact with the first evaporator, so as to absorb or release heat to the first storage compartment, thereby enabling the first storage compartment to have both freezing and heating functions.
[0012] In one possible design, the vehicle refrigerator further includes at least one second storage compartment, the second storage compartment including a second evaporator connected in series with the first evaporator and connected between the second flow regulator and the inlet of the compressor.
[0013] In this embodiment, the compressor discharges high-temperature and high-pressure gaseous refrigerant, which flows into the condenser through a pipeline. In the condenser, the refrigerant condenses and liquefies into high-temperature and high-pressure liquid refrigerant. The liquid refrigerant then flows into the second evaporator through a pipeline, where it rapidly evaporates and absorbs heat from the second storage chamber, thereby cooling the second storage chamber.
[0014] At the same time, by reducing the throttling cross-section of the third flow regulator and increasing the pressure of the second evaporator, the temperature of the second evaporator is increased, making the temperature of the second evaporator higher than that of the evaporator in the passenger compartment. This allows the second storage compartment with the second evaporator to reach a refrigeration temperature above 0°C, thus enabling the second storage compartment to have a refrigeration function.
[0015] In one possible design, the vehicle refrigerator further includes at least one second storage compartment, the second storage compartment including a second evaporator connected in parallel with the first evaporator and connected between the second flow regulator and the inlet of the compressor.
[0016] In this embodiment, the compressor discharges high-temperature and high-pressure gaseous refrigerant, which flows into the condenser through a pipeline. In the condenser, the refrigerant condenses and liquefies into high-temperature and high-pressure liquid refrigerant. The liquid refrigerant then flows into the second evaporator through a pipeline, where it rapidly evaporates and absorbs heat from the second storage chamber, thereby cooling the second storage chamber.
[0017] In one possible design, the end of the semiconductor cooler that is in contact with the first evaporator is designated as the first end.
[0018] The semiconductor cooler is provided with a first power terminal and a second power terminal that are electrically connected to a power source.
[0019] When the first terminal is positive and the second terminal is negative, the first terminal is the cold terminal and the first storage compartment is used for refrigeration.
[0020] When the first terminal is the negative terminal and the second terminal is the positive terminal, the first terminal is the hot terminal, and the first storage chamber is used for heating.
[0021] In this embodiment, the semiconductor cooler has a first end and a second end disposed opposite to each other. The first end is the cold end face, and the second end is the hot end face. The first evaporator is fitted to the first end (cold end face). In this case, the liquid refrigerant in the first evaporator can absorb the cooling energy of the semiconductor cooler and release this cooling energy into the first storage chamber to absorb heat from the first storage chamber, thereby cooling the first storage chamber and enabling it to have a freezing function.
[0022] When the first storage compartment is changed from a freezing compartment to a heating compartment, the current direction of the semiconductor cooler can be adjusted so that the first end is the hot end and the second end is the cold end. At this time, the first evaporator is fitted to the first end (hot end), and the liquid refrigerant in the first evaporator can absorb the heat from the semiconductor cooler and release heat into the first storage compartment to absorb the coldness in the first storage compartment, thereby heating the first storage compartment and enabling it to have a heating function.
[0023] In one possible design, the temperature of the first storage compartment is -20° to 0° when it serves as a freezer, and is 50° to 60° when it serves as a heater, and / or the temperature of the second storage compartment is 0° to 20°.
[0024] In this embodiment, the temperature of the first storage compartment as a freezer can be between -20°C and 0°C. This temperature effectively inhibits bacterial growth, maintains food freshness, and extends shelf life. For example, the temperature of the first storage compartment as a freezer can be set to -20°C, -19°C, -18°C, -17°C, -16°C, -15°C, -14°C, -13°C, -12°C, -11°C, -10°C, -9°C, -8°C, -7°C, -6°C, -5°C, -4°C, -3°C, -2°C, or -1°C. The freezer temperature can be adjusted in 0.5°C increments. The freezer temperature can also be further increased or decreased according to power requirements.
[0025] When the first storage compartment is used as a heating chamber, the temperature can be between 50°C and 60°C. This temperature is sufficient to heat the food and make it delicious. For example, the temperature of the first storage compartment as a heating chamber can be set to 50°C, 51°C, 52°C, 53°C, 54°C, 55°C, 56°C, 57°C, 58°C, 59°C, 60°C, etc. The temperature of the heating chamber can be adjusted in 0.5°C increments. The temperature of the heating chamber can also be further increased or decreased according to power requirements.
[0026] The temperature of the second storage compartment can range from 0℃ to 20℃. This temperature extends the shelf life and preserves the nutritional value and sensory qualities of the food. For example, the temperature of the second storage compartment can be set at 0℃, 1℃, 2℃, 3℃, 4℃, 5℃, 6℃, 7℃, 8℃, 9℃, 10℃, 11℃, 12℃, 13℃, 14℃, 15℃, 16℃, 17℃, 18℃, 19℃, and 20℃. The temperature of the refrigerator compartment can be adjusted in 0.5℃ increments. The temperature of the refrigerator compartment can also be further increased or decreased according to power requirements.
[0027] In one possible design, the first storage compartment and / or the second storage compartment are provided with heat storage material.
[0028] In this embodiment, when the first storage chamber is used as a freezer, the heat storage material can absorb and store a large amount of cold energy when the first storage chamber is at a low temperature, and release the cold energy when the temperature inside the first storage chamber rises, thereby maintaining the low-temperature environment (freezing environment) inside the first storage chamber for a longer period of time. When the first storage chamber is used as a heater, the heat storage material can absorb and store a large amount of heat energy when the first storage chamber is at a high temperature, and release the heat when the temperature inside the first storage chamber decreases, thereby maintaining the high-temperature environment (heating environment) inside the first storage chamber for a longer period of time.
[0029] The heat storage material can absorb and store a large amount of cold energy when the second storage chamber is at a low temperature, and can release the cold energy when the temperature in the second storage chamber rises, so as to maintain the low temperature environment (refrigeration environment) in the second storage chamber for a longer period of time.
[0030] In one possible design, the heat storage material is a mixture of water or the like.
[0031] In this embodiment, the mixture of water and other materials is a material that has both cold and heat storage functions. Alternatively, other materials with both cold and heat storage functions can be used as heat storage materials, which can be set according to the actual situation, and this embodiment does not limit them.
[0032] In one possible design, the vehicle thermal management system includes a third flow regulator, the inlet of which is connected to the outlet of the vehicle refrigerator and the inlet of the compressor.
[0033] In this embodiment, the third flow regulator functions as a pressure regulator. When the temperature of the first and second storage chambers needs to be increased, the throttling cross-section of the third flow regulator can be reduced, increasing the pressure of the first and second evaporators, thereby increasing their temperatures. When the temperature of the first and second storage chambers needs to be decreased, the throttling cross-section of the third flow regulator can be increased, decreasing the pressure of the first and second evaporators, thereby decreasing their temperatures.
[0034] In one possible design, the vehicle thermal management system further includes a fourth flow regulator and a battery cooler for cooling the vehicle's battery.
[0035] The inlet of the fourth flow regulator is connected to the outlet of the condenser, the outlet of the fourth flow regulator is connected to the inlet of the battery cooler, and the outlet of the battery cooler is connected to the inlet of the compressor.
[0036] In this embodiment, the high-temperature, high-pressure gaseous refrigerant discharged from the compressor flows into the condenser through a pipeline. In the condenser, it condenses and liquefies into a high-temperature, high-pressure liquid refrigerant, simultaneously releasing heat to the external environment (atmosphere). The liquid refrigerant then flows through a pipeline into the battery cooler, where it vaporizes and absorbs heat from the coolant in the battery pack's cooling circuit, thus cooling the battery pack. The gaseous refrigerant discharged from the battery cooler can also flow back to the compressor for cyclic compression.
[0037] In a second aspect, this application provides a vehicle, the vehicle comprising:
[0038] Body;
[0039] A vehicle thermal management system is installed on the vehicle body, and the vehicle thermal management system is the vehicle thermal management system described above.
[0040] In this embodiment, by integrating the vehicle refrigerator into the vehicle thermal management system, the needs of both vehicle thermal management and the vehicle refrigerator are taken into account. Attached Figure Description

Detailed Implementation
[0050] A car refrigerator is a refrigerated cabinet that can be carried in a car. Because car refrigerators are installed in the passenger compartment, they have problems such as generating heat that causes the temperature inside the passenger compartment to rise, and they are also noisy, which affect the comfort of the passengers.
[0051] Therefore, this embodiment provides a vehicle to solve the above-mentioned technical problems.
[0052] Please refer to Figure 1, which is a schematic diagram of a vehicle. The vehicle includes the body and the vehicle thermal management system. The vehicle thermal management system is installed on the body and is mainly used to solve thermal-related problems of the whole vehicle, so that the various functional modules of the vehicle are in the optimal temperature range, thereby improving the performance, reliability and stability of the vehicle and enhancing the comfort of passengers.
[0053] It should be noted that the vehicle also includes other parts such as the chassis and electrical equipment. This embodiment does not limit the specific structure of the vehicle.
[0054] Figure 1 shows a flow diagram of a portion of the vehicle thermal management system 1 (the arrows indicate the direction of refrigerant flow). The vehicle thermal management system 1 includes a compressor 11, a condenser 12, a passenger compartment evaporator 13, a battery cooler 14, and an onboard refrigerator 15. The compressor 11 compresses the refrigerant into a high-temperature, high-pressure gas. The condenser 12 is typically installed in front of the car radiator to dissipate the heat of the refrigerant into the air, cooling and condensing the refrigerant into a high-pressure liquid. The passenger compartment evaporator 13 is usually located in the vehicle's ventilation ducts, rapidly evaporating the refrigerant and absorbing heat from the vehicle interior to achieve cooling. The battery cooler 14 introduces refrigerant to absorb heat from the coolant in the battery pack cooling circuit, carrying away the heat from the coolant through heat exchange, thus cooling the battery pack.
[0055] Please continue referring to Figure 1. The components connected in compressor 11, condenser 12, passenger compartment evaporator 13, battery cooler 14, and vehicle refrigerator 15 are all connected via pipe 16, allowing the refrigerant generated by compressor 11 and condenser 12 to flow through pipe 16 to passenger compartment evaporator 13, battery cooler 14, and vehicle refrigerator 15. Specifically, passenger compartment evaporator 13, battery cooler 14, and vehicle refrigerator 15 are arranged in parallel in the flow path, allowing three flow loops to be formed among compressor 11, condenser 12, passenger compartment evaporator 13, battery cooler 14, and vehicle refrigerator 15.
[0056] Specifically, in one of the loops, the outlet of compressor 11 is connected to the inlet of condenser 12, the outlet of condenser 12 is connected to the inlet of crew compartment evaporator 13, and the outlet of crew compartment evaporator 13 is connected to the inlet of compressor 11, so that compressor 11, condenser 12 and crew compartment evaporator 13 form a loop.
[0057] In this circuit, the compressor 11 discharges high-temperature, high-pressure gaseous refrigerant, which flows into the condenser 12 through pipe 16. In the condenser 12, the refrigerant condenses and liquefies into high-temperature, high-pressure liquid refrigerant, simultaneously releasing heat to the external environment (atmosphere). The liquid refrigerant then flows through pipe 16 into the passenger compartment evaporator 13, where it rapidly evaporates, absorbing heat from the air inside the passenger compartment and thus cooling the passenger compartment. The gaseous refrigerant discharged from the passenger compartment evaporator 13 can also flow back to the compressor 11 for cyclic compression. The passenger compartment cooling and heating technologies are existing technologies, and the passenger compartment heating process can refer to existing technologies; therefore, it will not be described in detail here.
[0058] The temperature of the evaporator 13 in the crew compartment is typically -6°C to 5°C. That is to say, the temperature of the refrigerant formed by the compressor 11 and the condenser 12 is -6°C to 5°C.
[0059] Further, referring to Figure 2, in this circuit, the vehicle heat treatment system also includes a first flow regulator 13a, which is installed at the inlet of the passenger compartment evaporator 13. The first flow regulator 13a can control the flow rate of refrigerant to the passenger compartment evaporator 13 by changing its throttling cross-section, thereby regulating the evaporation pressure of the passenger compartment evaporator 13 and ensuring the stability of the vehicle heat management system 1.
[0060] The first flow regulator can be a throttle valve, or it can be a pipeline whose cross-sectional area changes to achieve a throttling effect. This application describes an embodiment where the first flow regulator is a throttle valve as an example.
[0061] In another circuit, the battery cooler 14 is connected in parallel with the crew compartment evaporator 13. Specifically, the outlet of the compressor 11 is connected to the inlet of the condenser 12, the outlet of the condenser 12 is connected to the inlet of the battery cooler 14, and the outlet of the battery cooler 14 is connected to the inlet of the compressor 11, so that the compressor 11, the condenser 12 and the battery cooler 14 form a circuit.
[0062] In this circuit, the compressor 11 discharges high-temperature, high-pressure gaseous refrigerant, which flows into the condenser 12 through pipe 16. In the condenser 12, the refrigerant condenses and liquefies into high-temperature, high-pressure liquid refrigerant, simultaneously releasing heat to the external environment (atmosphere). The liquid refrigerant then flows through pipe 16 into the battery cooler 14, where it vaporizes and absorbs heat from the coolant in the battery pack cooling circuit, thus cooling the battery pack. The gaseous refrigerant discharged from the battery cooler 14 can also flow back to the compressor 11 for cyclic compression.
[0063] Further, referring to Figure 1, a fourth flow regulator 14a is also provided in this circuit of the vehicle thermal management system. The fourth flow regulator 14a is installed at the inlet of the battery cooler 14. The fourth flow regulator 14a can control the flow rate of refrigerant to the battery cooler 14 by changing its throttling cross-section, thereby regulating the evaporation pressure of the battery cooler 14 and ensuring the stability of the vehicle thermal management system 1.
[0064] In another circuit, the vehicle refrigerator 15 is connected in parallel with the passenger compartment evaporator 13. Specifically, the outlet of the compressor 11 is connected to the inlet of the condenser 12, the outlet of the condenser 12 is connected to the inlet of the vehicle refrigerator 15, and the outlet of the vehicle refrigerator 15 is connected to the inlet of the compressor 11, so that the compressor 11, the condenser 12 and the vehicle refrigerator 15 form a circuit.
[0065] In this circuit, the compressor 11 discharges high-temperature, high-pressure gaseous refrigerant, which flows into the condenser 12 through pipe 16. In the condenser 12, the refrigerant condenses and liquefies into high-temperature, high-pressure liquid refrigerant, simultaneously releasing heat to the external environment (atmosphere). The liquid refrigerant then flows through pipe 16 into the vehicle refrigerator 15, enabling the vehicle refrigerator 15 to both cool and heat (the specific implementation of cooling and heating in the vehicle refrigerator 15 is described below). The gaseous refrigerant discharged from the vehicle refrigerator 15 flows back to the compressor 11, achieving cyclic compression.
[0066] Further, referring to Figure 1, a second flow regulator 15b is also provided in this circuit of the vehicle heat treatment system. The second flow regulator 15b is installed at the inlet of the vehicle refrigerator 15. The second flow regulator 15b can control the flow rate of refrigerant to the vehicle refrigerator 15 by changing its throttling cross-section, thereby adjusting the evaporation pressure of the vehicle refrigerator 15 and ensuring the stability of the vehicle heat management system 1.
[0067] It should be noted that in the three circuits mentioned above, all three circuits can be turned on simultaneously, such as compressor 11, condenser 12, passenger compartment evaporator 13, battery cooler 14, and vehicle refrigerator 15 operating at the same time. The specific settings can be configured according to actual conditions, and this embodiment does not impose any limitations on them.
[0068] Alternatively, in the three circuits mentioned above, two of the circuits can be activated simultaneously. For example, compressor 11, condenser 12, passenger compartment evaporator 13, and battery cooler 14 can operate simultaneously while the vehicle refrigerator 15 stops operating; or compressor 11, condenser 12, passenger compartment evaporator 13, and vehicle refrigerator 15 can operate simultaneously while the battery cooler 14 stops operating; or compressor 11, condenser 12, battery cooler 14, and vehicle refrigerator 15 can operate simultaneously while the passenger compartment evaporator 13 stops operating. The specific settings can be configured according to actual conditions, and this embodiment does not impose limitations here.
[0069] Alternatively, in the three circuits mentioned above, one circuit can be activated, such as compressor 11, condenser 12, and passenger compartment evaporator 13, or compressor 11, condenser 12, and battery cooler 14, or compressor 11, condenser 12, and vehicle refrigerator 15. The specific settings can be configured according to actual conditions, and this embodiment does not limit them.
[0070] Of course, when the vehicle is turned off, the three circuits mentioned above will stop operating simultaneously.
[0071] It should also be noted that other components such as fans and evaporators may also be provided in the flow path of the vehicle thermal management system 1. This embodiment does not limit the structure of the vehicle thermal management system 1.
[0072] In this embodiment, the vehicle refrigerator 15 is integrated into the vehicle thermal management system 1, allowing it to share the existing compressor 11 and condenser 12 of the system. This eliminates the need for a separate compressor 11 and condenser 12 for the refrigerator 15, resulting in cost savings, increased capacity, and reduced weight. Simultaneously, the heat load of the refrigerator 15 can be dissipated outside the vehicle along with the heat from the thermal management system 1, preventing heat generated by the refrigerator from being released inside the passenger compartment and improving passenger comfort. Furthermore, moving the compressor 11 and condenser 12 outside the passenger compartment reduces noise generated by the refrigerator 15, further enhancing passenger comfort. This embodiment, by integrating the refrigerator 15 into the vehicle thermal management system 1, balances the needs of both overall vehicle thermal management and the refrigerator 15, providing flexible vehicle layout.
[0073] In this embodiment, by integrating the vehicle refrigerator into the vehicle management system, the problems of heat load generated by the vehicle refrigerator being discharged into the passenger compartment and excessive noise are solved. Furthermore, this vehicle refrigerator is a dual-temperature range refrigerator with both freezing and heating functions. A schematic diagram of the vehicle refrigerator will be described in detail below with reference to the accompanying drawings.
[0074] Please refer to Figure 3 for details. Figure 3 is a partial flow path diagram of the vehicle thermal management system 1 involving the vehicle refrigerator 15 (the arrows in the figure indicate the direction of refrigerant flow). The vehicle refrigerator 15 includes at least one first storage compartment 151. The first storage compartment 151 includes a first evaporator 151a and a semiconductor cooler 151b that are attached to each other. Referring to Figure 2, the liquid refrigerant can flow from the condenser 12 to the first evaporator 151a. The first evaporator 151a can absorb heat or cold from the semiconductor cooler 151b through the liquid refrigerant and release more heat or cold into the first storage compartment 151.
[0075] Please continue referring to Figure 3. The vehicle thermal management system 1 is also equipped with a third flow regulator 15a, which is located downstream of the first evaporator 151a. The third flow regulator 15a can adjust the pressure of the first evaporator 151a by changing its throttling cross-section, thereby adjusting the temperature of the first evaporator 151a. Specifically, by reducing the throttling cross-section of the third flow regulator 15a, the pressure of the first evaporator 151a is increased, so that the temperature of the first evaporator 151a is higher than the temperature of the passenger compartment evaporator 13 (the temperature of the refrigerant formed by the compressor 11 and the condenser 12), thereby enabling the first storage compartment 151, which is equipped with the first evaporator 151a and the semiconductor cooler 151b, to have a freezing or heating function (the temperature inside the first storage compartment 151 is further increased or decreased under the action of the first evaporator 151a and the semiconductor cooler 151b, as described in detail below).
[0076] Referring to Figures 2 and 3, the following section describes in detail how the first storage compartment 151 achieves both freezing and heating functions. The outlet of the compressor 11 is connected to the inlet of the condenser 12 via pipe 16. The inlet of the first evaporator 151a is connected to the outlet of the condenser 12. The outlet of the first evaporator 151a is connected to the inlet of the third flow regulator 15a. The outlet of the third flow regulator 15a is connected to the inlet of the compressor 11.
[0077] In other words, the compressor 11, condenser 12, first evaporator 151a and third flow regulator 15a can form a flow path loop, so that the high-temperature and high-pressure gaseous refrigerant discharged by the compressor 11 flows into the condenser 12 through the pipe 16, where it is condensed and liquefied into a high-temperature and high-pressure liquid refrigerant, and the liquid refrigerant flows into the first evaporator 151a through the pipe 16.
[0078] At this time, by reducing the throttling cross section of the third flow regulator 15a, the pressure of the first evaporator 151a is increased, thereby increasing the temperature of the first evaporator 151a, so that the temperature of the first evaporator 151a is higher than the temperature of the crew cabin evaporator 13.
[0079] Meanwhile, one end face of the first evaporator 151a is fitted to one end face of the semiconductor cooler 151b, and the first evaporator 151a can absorb the heat or cold energy of the semiconductor cooler 151b to achieve cooling or heating of the second storage chamber 152.
[0080] It should be noted that thermoelectric coolers are a current technology. Thermoelectric cooler TEC (151b), also called a thermoelectric cooler, is a heat dissipation device made using the Peltier effect, also known as the thermoelectric effect. In a circuit, a P-type semiconductor and an N-type semiconductor are placed to form a unit. When energized, electron-hole pairs are generated at one end, reducing internal energy and lowering temperature, forming a cold end. At the other end, electron-hole recombination increases internal energy and raises temperature, forming a hot end.
[0081] In other words, the current in the thermoelectric cooler 151b can be either forward or reverse. Forward current will heat the thermoelectric cooler 151b, while reverse current will cool it down. Therefore, by controlling the direction and magnitude of the current in the thermoelectric cooler 151b, heat can be absorbed and released at its two ends respectively, achieving the purpose of cooling and heating. That is, the thermoelectric cooler 151b operates as a cooler or heater depending on the direction of the current. The temperature difference between the hot and cold ends of the thermoelectric cooler 151b can reach 60℃~70℃, and the cold end temperature can reach -20℃~-10℃.
[0082] When the first storage compartment 151 is used as a freezer, please refer to Figure 4. Figure 4 is a schematic diagram of the connection between the first evaporator 151a and the semiconductor cooler 151b. The semiconductor cooler 151b has a first end 151b1 and a second end 151b2 arranged opposite to each other. The semiconductor cooler 151b is provided with a first terminal (not shown in the figure) and a second terminal (not shown in the figure) that are electrically connected to a power source. When the first terminal is the positive electrode and the second terminal is the negative electrode, the first end 151b is the cold end face. At this time, the first end 151b1 is the cold end face, the second end 151b2 is the hot end face, and the first evaporator 151a is in close contact with the first end 151b1 (cold end face). Then, the liquid refrigerant in the first evaporator 151a can absorb the cold energy of the semiconductor cooler 151b and release the cold energy into the first storage compartment 151 to absorb the heat in the first storage compartment 151, thereby cooling the first storage compartment 151. Since the temperature of the first end 151b1 is 20℃ to -10℃ at this time, the first evaporator 151a, in conjunction with the connected semiconductor cooler 151b, further reduces the temperature inside the first storage chamber 151, thereby enabling the first storage chamber 151 to have a freezing function.
[0083] In this embodiment, when the first storage compartment 151 is used as a freezer, the temperature can be between -20°C and 0°C. This temperature effectively inhibits bacterial growth, maintains food freshness, and also helps extend the shelf life of the food. For example, the temperature of the first storage compartment 151 as a freezer can be set to -20°C, -19°C, -18°C, -17°C, -16°C, -15°C, -14°C, -13°C, -12°C, -11°C, -10°C, -9°C, -8°C, -7°C, -6°C, -5°C, -4°C, -3°C, -2°C, or -1°C. The freezer temperature can be adjusted in 0.5°C increments. The freezer temperature can also be further increased or decreased according to power requirements. The specific settings can be customized according to the user's usage, and this embodiment does not impose any limitations on them.
[0084] In this embodiment, the third flow regulator 15a functions as a pressure regulator. When the temperature of the first storage chamber 151 needs to be increased, the throttling cross-section of the third flow regulator 15a can be reduced to increase the pressure of the first evaporator 151a, thereby increasing the temperature of the first evaporator 151a. When the temperature of the first storage chamber 151 needs to be decreased, the throttling cross-section of the third flow regulator 15a can be increased to decrease the pressure of the first evaporator 151a, thereby decreasing the temperature of the first evaporator 151a.
[0085] When the first storage chamber 151 is changed from a freezing chamber to a heating chamber, the current direction of the semiconductor cooler 151b can be adjusted, that is, the first terminal is adjusted to be negative and the second terminal is adjusted to be positive, so that the first end 151b1 is the hot end and the second end 151b2 is the cold end. At this time, the first evaporator 151a is attached to the first end 151b1 (hot end), and the liquid refrigerant in the first evaporator 151a can absorb the heat of the semiconductor cooler 151b and release heat into the first storage chamber 151 to absorb the coldness in the first storage chamber 151, thereby achieving heating of the first storage chamber 151. Since the temperature of the first end 151b1 is 0℃~60℃ at this time, the first evaporator 151a, in combination with the connected semiconductor cooler 151b, further increases the temperature in the first storage chamber 151, thereby enabling the first storage chamber 151 to have a heating function.
[0086] In this embodiment, when the first storage chamber 151 functions as a heating chamber, the temperature can be between 50°C and 60°C. This temperature is sufficient to heat food and make it delicious. For example, the temperature of the first storage chamber 151 as a heating chamber can be set to 50°C, 51°C, 52°C, 53°C, 54°C, 55°C, 56°C, 57°C, 58°C, 59°C, 60°C, etc. The temperature of the heating chamber can be adjusted in 0.5°C increments. The temperature of the heating chamber can also be further increased or decreased according to power requirements. Specific settings can be made according to user needs, and this embodiment does not limit this.
[0087] In this embodiment, the third flow regulator 15a functions as a pressure regulator. When the temperature of the first storage chamber 151 needs to be increased, the throttling cross-section of the third flow regulator 15a can be reduced to increase the pressure of the first evaporator 151a, thereby increasing the temperature of the first evaporator 151a. When the temperature of the first storage chamber 151 needs to be decreased, the throttling cross-section of the third flow regulator 15a can be increased to decrease the pressure of the first evaporator 151a, thereby decreasing the temperature of the first evaporator 151a.
[0088] In this embodiment, by integrating the vehicle-mounted refrigerator with a first storage compartment into the vehicle's thermal management system, the problems of heat load being discharged into the passenger compartment and excessive noise generated by the vehicle-mounted refrigerator are solved. Furthermore, by changing the direction of the current flowing into the semiconductor cooler, the vehicle-mounted refrigerator allows the cooling or heating end of the semiconductor cooler to contact the first evaporator, thereby absorbing or releasing heat into the first storage compartment, thus enabling the first storage compartment to have both freezing and heating functions.
[0089] In some embodiments, the vehicle refrigerator is also a three-temperature zone refrigerator with refrigeration, freezing, and heating functions. A schematic diagram of the vehicle refrigerator will be described in detail below with reference to the accompanying drawings.
[0090] Please refer to Figure 5 for details. Figure 5 is a flow diagram of the vehicle thermal management system 1 in another embodiment (the arrows in the figure indicate the direction of the cold medium flow). The vehicle thermal management system 1 includes a compressor 11, a condenser 12, a passenger compartment evaporator 13, a battery cooler 14, and an on-board refrigerator 15. The passenger compartment evaporator 13, the battery cooler 14, and the on-board refrigerator 15 are arranged in parallel in the flow path, so that the compressor 11, condenser 12, passenger compartment evaporator 13, battery cooler 14, and on-board refrigerator 15 can be connected to form three flow loops. For details, please refer to the above text; this embodiment will not be repeated here.
[0091] Figure 6 is a partial flow path diagram of the vehicle thermal management system involving the vehicle refrigerator 15 in Figure 5 (the arrows in the figure indicate the flow direction of the refrigerant). Please refer to Figures 5 and 6. The vehicle refrigerator 15 includes at least a first storage compartment 151 and a second storage compartment 152. The first storage compartment 151 can freeze or heat items, and the second storage compartment 152 can refrigerate items.
[0092] The vehicle refrigerator 15 in this embodiment has refrigeration, freezing and heating functions, providing a rich set of features and enhancing the user experience.
[0093] The first storage chamber 151 is equipped with a first evaporator 151a and a semiconductor cooler 151b in close contact with each other, while the second storage chamber 152 is equipped with a second evaporator 152a. Liquid refrigerant can flow from the condenser 12 to the first evaporator 151a and the second evaporator 152a. The first evaporator 151a can absorb heat or cold from the semiconductor cooler 151b through the liquid refrigerant, releasing more heat or cold into the first storage chamber 151. The second evaporator 152a can rapidly evaporate the liquid refrigerant, absorbing heat from the second storage chamber 152.
[0094] In this embodiment, the first evaporator 151a is located downstream of the second evaporator 152a, or the first evaporator 151a may also be located upstream of the second evaporator 152a. The specific location can be set according to the actual situation, and this embodiment does not limit it.
[0095] Please refer to Figures 5 and 6. The vehicle thermal management system 1 is also provided with a third flow regulator 15a. The third flow regulator 15a is located downstream of the first evaporator 151a. The third flow regulator 15a can adjust the pressure of the second evaporator 152a and the first evaporator 151a by changing its throttling cross section, so as to adjust the temperature of the second evaporator 152a and the first evaporator 151a. Specifically, the throttling cross-section of the third flow regulator 15a is reduced, causing the pressure of the second evaporator 152a and the first evaporator 151a to increase, so that the temperature of the second evaporator 152a and the first evaporator 151a is higher than the temperature of the passenger compartment evaporator 13 (the temperature of the refrigerant formed by the compressor 11 and the condenser 12), thereby giving the second storage compartment 152, which is equipped with the second evaporator 152a, a refrigeration function, and giving the first storage compartment 151, which is equipped with the first evaporator 151a and the semiconductor cooler 151b, a freezing or heating function (the temperature in the first storage compartment 151 is further increased or decreased under the action of the first evaporator 151a and the semiconductor cooler 151b, as described in detail below).
[0096] Specifically, referring to Figures 5 and 6, the following describes in detail how the second storage compartment 152 achieves its refrigeration function. The outlet of the compressor 11 is connected to the inlet of the condenser 12 via pipe 16. The inlet of the second evaporator 152a is connected to the outlet of the condenser 12 via pipe 16. The second evaporator 152a is connected to the first evaporator 151a via pipe 16. The third flow regulator 15a is located downstream of the second evaporator 152a and the first evaporator 151a, and the outlet of the third flow regulator 15a is connected to the inlet of the compressor 11.
[0097] In other words, the compressor 11, condenser 12, second evaporator 152a, and third flow regulator 15a can form a flow path loop, so that the high-temperature and high-pressure gaseous refrigerant discharged by the compressor 11 flows into the condenser 12 through the pipe 16, where it is condensed and liquefied into a high-temperature and high-pressure liquid refrigerant. The liquid refrigerant then flows into the second evaporator 152a through the pipe 16, where it rapidly evaporates and absorbs heat from the second storage chamber 152, thus cooling the second storage chamber 152.
[0098] At the same time, by reducing the throttling cross section of the third flow regulator 15a, the pressure of the second evaporator 152a is increased, thereby increasing the temperature of the second evaporator 152a, making the temperature of the second evaporator 152a higher than the temperature of the crew compartment evaporator 13, so that the second storage compartment 152 with the second evaporator 152a can reach a refrigeration temperature above 0°, thus enabling the second storage compartment 152 to have a refrigeration function.
[0099] In some embodiments, the temperature of the second storage compartment 152 can be between 0°C and 20°C. This temperature can extend the storage period and preserve the nutritional value and sensory properties of the food. Exemplarily, the temperature of the second storage compartment 152 can be set at 0°C, 1°C, 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, 11°C, 12°C, 13°C, 14°C, 15°C, 16°C, 17°C, 18°C, 19°C, 20°C, etc. The temperature of the refrigerator compartment can be adjusted in 0.5°C increments. The temperature of the refrigerator compartment can also be further increased or decreased according to power requirements. Specific settings can be made according to user needs, and this embodiment does not limit this.
[0100] In this embodiment, the third flow regulator 15a functions as a pressure regulator. When the temperature of the second storage chamber 152 needs to be increased (e.g., to 12 degrees Celsius), the throttling cross-section of the third flow regulator 15a can be reduced, increasing the pressure of the second evaporator 152a and thus increasing its temperature. When the temperature of the second storage chamber 152 needs to be decreased (e.g., to 8 degrees Celsius), the throttling cross-section of the third flow regulator 15a can be increased, decreasing the pressure of the second evaporator 152a and thus decreasing its temperature.
[0101] That is, the larger the throttling section of the third flow regulator 15a, the smaller the temperature difference between the second evaporator 152a and the crew compartment evaporator 13; the smaller the throttling section of the third flow regulator 15a, the larger the temperature difference between the second evaporator 152a and the crew compartment evaporator 13.
[0102] Please refer to Figures 5 and 6 for further details. The following describes in detail how the first storage compartment 151 achieves both freezing and heating functions. The outlet of the compressor 11 is connected to the inlet of the condenser 12 via pipe 16. The inlet of the first evaporator 151a is connected to the outlet of the condenser 12 via the second evaporator 152a. The third flow regulator 15a is located downstream of the first evaporator 151a, and its outlet is connected to the inlet of the compressor 11.
[0103] In other words, the compressor 11, condenser 12, first evaporator 151a and third flow regulator 15a can form a flow path loop, so that the high-temperature and high-pressure gaseous refrigerant discharged by the compressor 11 flows into the condenser 12 through the pipe 16, where it is condensed and liquefied into a high-temperature and high-pressure liquid refrigerant, and the liquid refrigerant flows into the first evaporator 151a through the pipe 16.
[0104] At this time, by reducing the throttling cross section of the third flow regulator 15a, the pressure of the first evaporator 151a is increased, thereby increasing the temperature of the first evaporator 151a, so that the temperature of the first evaporator 151a is higher than the temperature of the crew cabin evaporator 13.
[0105] Meanwhile, one end face of the first evaporator 151a is fitted to one end face of the semiconductor cooler 151b, and the first evaporator 151a can absorb the heat or cold energy of the semiconductor cooler 151b to achieve cooling or heating of the first storage chamber 151.
[0106] It should be noted that thermoelectric coolers are a current technology. Thermoelectric cooler TEC (151b), also called a thermoelectric cooler, is a heat dissipation device made using the Peltier effect, also known as the thermoelectric effect. In a circuit, a P-type semiconductor and an N-type semiconductor are placed to form a unit. When energized, electron-hole pairs are generated at one end, reducing internal energy and lowering temperature, forming a cold end. At the other end, electron-hole recombination increases internal energy and raises temperature, forming a hot end.
[0107] In other words, the current in the thermoelectric cooler 151b can be either forward or reverse. Forward current will heat the thermoelectric cooler 151b, while reverse current will cool it down. Therefore, by controlling the direction and magnitude of the current in the thermoelectric cooler 151b, heat can be absorbed and released at its two ends respectively, achieving the purpose of cooling and heating. That is, the operation of the thermoelectric cooler 151b as a cooler or heater depends on the direction of the current.
[0108] Among them, the temperature difference between the hot and cold ends of the semiconductor cooler 151b can reach 60℃~70℃, and the cold end temperature can reach -20℃~-10℃.
[0109] When the first storage compartment 151 functions as a freezer, referring to Figure 4, the semiconductor cooler 151b has a first end 151b1 and a second end 151b2 arranged opposite to each other. At this time, the first end 151b1 is the cold end face, and the second end 151b2 is the hot end face. The first evaporator 151a is attached to the first end 151b1 (cold end face). In this case, the liquid refrigerant in the first evaporator 151a can absorb the cooling energy of the semiconductor cooler 151b and release this cooling energy into the first storage compartment 151 to absorb heat within the first storage compartment 151, thus achieving cooling of the first storage compartment 151. Since the temperature of the first end 151b1 is 20℃ to -10℃ at this time, the first evaporator 151a, in conjunction with the connected semiconductor cooler 151b, further reduces the temperature within the first storage compartment 151, thereby enabling the first storage compartment 151 to have a freezing function.
[0110] In this embodiment, when the first storage compartment 151 is used as a freezer, the temperature can be between -20°C and 0°C. This temperature effectively inhibits bacterial growth, maintains food freshness, and also helps extend the shelf life of the food. For example, the temperature of the first storage compartment 151 as a freezer can be set to -20°C, -19°C, -18°C, -17°C, -16°C, -15°C, -14°C, -13°C, -12°C, -11°C, -10°C, -9°C, -8°C, -7°C, -6°C, -5°C, -4°C, -3°C, -2°C, or -1°C. The freezer temperature can be adjusted in 0.5°C increments. The freezer temperature can also be further increased or decreased according to power requirements. The specific settings can be customized according to the user's usage, and this embodiment does not impose any limitations on them.
[0111] In this embodiment, the third flow regulator 15a functions as a pressure regulator. When the temperature of the first storage chamber 151 needs to be increased, the throttling cross-section of the third flow regulator 15a can be reduced to increase the pressure of the first evaporator 151a, thereby increasing the temperature of the first evaporator 151a. When the temperature of the first storage chamber 151 needs to be decreased, the throttling cross-section of the third flow regulator 15a can be increased to decrease the pressure of the first evaporator 151a, thereby decreasing the temperature of the first evaporator 151a.
[0112] When the first storage chamber 151 is changed from a freezing chamber to a heating chamber, the current direction of the semiconductor cooler 151b can be adjusted so that the first end 151b1 is the hot end face and the second end 151b2 is the cold end face. At this time, the first evaporator 151a is attached to the first end 151b1 (hot end face), and the liquid refrigerant in the first evaporator 151a can absorb the heat from the semiconductor cooler 151b, releasing heat into the first storage chamber 151 to absorb the coldness within the first storage chamber 151, thus heating the first storage chamber 151. Since the temperature of the first end 151b1 is 0℃~60℃ at this time, the first evaporator 151a, combined with the connected semiconductor cooler 151b, further increases the temperature inside the first storage chamber 151, thereby enabling the first storage chamber 151 to have a heating function.
[0113] In this embodiment, when the first storage chamber 151 functions as a heating chamber, the temperature can be between 50°C and 60°C. This temperature is sufficient to heat food and make it delicious. For example, the temperature of the first storage chamber 151 as a heating chamber can be set to 50°C, 51°C, 52°C, 53°C, 54°C, 55°C, 56°C, 57°C, 58°C, 59°C, 60°C, etc. The temperature of the heating chamber can be adjusted in 0.5°C increments. The temperature of the heating chamber can also be further increased or decreased according to power requirements. Specific settings can be made according to user needs, and this embodiment does not limit this.
[0114] In this embodiment, the third flow regulator 15a functions as a pressure regulator. When the temperature of the first storage chamber 151 needs to be increased, the throttling cross-section of the third flow regulator 15a can be reduced to increase the pressure of the first evaporator 151a, thereby increasing the temperature of the first evaporator 151a. When the temperature of the first storage chamber 151 needs to be decreased, the throttling cross-section of the third flow regulator 15a can be increased to decrease the pressure of the first evaporator 151a, thereby decreasing the temperature of the first evaporator 151a.
[0115] It should be noted that when adjusting the throttling section of the third flow regulator 15a to adjust the temperatures of the second evaporator 152a and the first evaporator 151a, the second evaporator 152a and the first evaporator 151a reach the same temperature. For example, by controlling the throttling section of the third flow regulator 15a, the temperature of the second evaporator 152a can be kept at 5°C, and the temperature of the first evaporator 151a can also be kept at 5°C.
[0116] In the embodiment shown in Figure 6, the second evaporator 152a and the first evaporator 151a are connected in series. Alternatively, in some embodiments, the second evaporator 152a and the first evaporator 151a may be connected in parallel. Please refer to Figure 7 for details. Figure 7 shows a flow path diagram of the second evaporator 152a and the first evaporator 151a connected in parallel. This embodiment reduces the risk of the first evaporator 151a being affected when the second evaporator 152a malfunctions by connecting the second evaporator 152a and the first evaporator 151a in parallel. Specifically, the second evaporator 152a and the first evaporator 151a can be set in series or in parallel according to the actual situation, and this embodiment does not limit this.
[0117] In this embodiment, two third flow regulators 15a and two second flow regulators 15b can be provided, such that the inlet of the second evaporator 152a and the inlet of the first evaporator 151a are both equipped with second flow regulators 15b, and the outlet of the second evaporator 152a and the outlet of the first evaporator 151a are both equipped with third flow regulators 15a. Alternatively, the second evaporator 152a and the first evaporator 151a can share one third flow regulator 15a and one second flow regulator 15b to save costs. The specific configuration can be determined according to actual conditions, and this embodiment does not impose any limitations.
[0118] Figure 8 shows a flow path diagram of the vehicle refrigerator 15 in another embodiment. In some embodiments, in addition to the second storage compartment 152 and the first storage compartment 151, the vehicle refrigerator 15 also has a third storage compartment 153, which is equipped with an evaporator and a thermoelectric cooler. The second storage compartment 152 can be configured as a refrigerator compartment, the first storage compartment 151 as a freezer compartment, and the third storage compartment 153 as a heating compartment. This allows the vehicle refrigerator 15 to simultaneously perform refrigeration, freezing, and heating functions without requiring the user to adjust the current direction of the thermoelectric cooler in the first storage compartment 151 to change its temperature, thus further enhancing the user experience. Specific configurations can be made according to actual conditions, and this embodiment does not impose limitations.
[0119] In this embodiment, the evaporator can be connected in parallel with the first evaporator and the second evaporator, or the evaporator can be connected in series with the first evaporator and the second evaporator, or two of the evaporators, the first evaporator and the second evaporator can be connected in parallel or in series. The specific configuration can be determined according to the actual situation, and this embodiment does not impose any limitations.
[0120] In some embodiments, the vehicle refrigerator 15 may further include a fourth storage compartment, a fifth storage compartment, etc. Thus, the vehicle refrigerator 15 having multiple storage compartments can meet the user's needs for refrigerating, freezing, and heating items, further enhancing the user's driving experience. Specific configurations can be made according to actual circumstances, and this embodiment does not impose limitations.
[0121] In this embodiment, each storage compartment in the vehicle refrigerator 15 is equipped with a corresponding evaporator or evaporator and semiconductor refrigerator according to its function. The evaporators of each storage compartment can be set in the flow path in series or in parallel.
[0122] In this embodiment, the storage compartments can be located in the same location within the carriage or distributed in different locations within the carriage. For example, both the front and rear passenger compartments may be equipped with refrigerated, frozen, and heated compartments for user convenience. Specific configurations can be determined based on actual circumstances, and this embodiment does not impose any limitations.
[0123] Please refer to Figures 5 and 6. The vehicle refrigerator 15 integrated in the vehicle thermal management system 1 requires the compressor 11 of the vehicle thermal management system 1 to be started every time the vehicle refrigerator 15 is working. This causes the compressor 11 to start and stop frequently, which has a significant impact on the lifespan of the compressor 11.
[0124] In some embodiments, the first storage chamber 151 is further provided with a heat storage material (not shown in the figure). The heat storage material is made of energy storage material and can prolong the duration of maintaining the temperature of the first storage chamber 151. That is, when the first storage chamber 151 is used as a freezer, the heat storage material can absorb and store a large amount of cold energy when the first storage chamber 151 is at a low temperature, and can release the cold energy when the temperature inside the first storage chamber 151 rises, so as to maintain the low temperature environment (freezing environment) inside the first storage chamber 151 for a longer period of time. When the first storage chamber 151 is used as a heater, the heat storage material can absorb and store a large amount of heat when the first storage chamber 151 is at a high temperature, and can release the heat when the temperature inside the first storage chamber 151 drops, so as to maintain the high temperature environment (heating environment) inside the first storage chamber 151 for a longer period of time.
[0125] Specifically, the heat storage material can be disposed at the first evaporator 151a. For example, if the first evaporator 151a has a porous structure, the heat storage material is disposed in the porous structure.
[0126] In this embodiment, the energy storage material in the first storage chamber 151 can be a mixture of water and other materials, which are materials that have both cold and heat storage functions, and the phase change temperature of the mixture is between 0 and 20 degrees Celsius. Alternatively, the energy storage material in the first storage chamber 151 can also be other materials with both cold and heat storage functions, which can be set according to the actual situation, and this embodiment does not limit it.
[0127] In some embodiments, the second storage chamber 152 is further provided with a heat storage material (not shown in the figure). The heat storage material is made of an energy storage material and can prolong the time for maintaining the temperature of the second storage chamber 152. That is, the heat storage material can absorb and store a large amount of cold energy when the second storage chamber 152 is at a low temperature, and can release the cold energy when the temperature inside the second storage chamber 152 rises, so as to maintain the low temperature environment (refrigeration environment) inside the second storage chamber 152 for a longer period of time.
[0128] Specifically, the heat storage material can be disposed at the second evaporator 152a. For example, if the second evaporator 152a has a porous structure, the heat storage material is disposed within the porous structure.
[0129] In this embodiment, the energy storage material in the second storage chamber 152 can be a mixture such as water, with a phase change temperature between 0 and 20 degrees Celsius. Alternatively, the energy storage material in the second storage chamber 152 can also be other materials with cold storage function, which can be set according to the actual situation and are not limited in this embodiment.
