[0038] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present invention and are not used to limit the present invention.
[0039] In order to better understand the technical solution of the present utility model, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0040] It is understandable that when the car is in operation, the ambient temperature varies greatly. In order to achieve stable driving, the exhaust and return air temperature of the car's compressor usually needs to be controlled within a reasonable range. If the return air temperature of the compressor is too high or too low, it will affect the reliability of the car system.
[0041] The automobile of the prior art usually includes a car refrigerator, a car air conditioner and a power supply device. In order to reduce the size, the car refrigerator, the car air conditioner and the power supply device generally share a compressor, and the exhaust and return air temperature of the compressor and the temperature of the evaporator are controlled within a reasonable range through the flow rate and the compressor speed, thereby ensuring the reliability of the automobile system. However, the range of controlling the exhaust and return air temperature of the compressor and the temperature of the evaporator through the flow rate and the compressor speed is limited, which easily causes the compressor to start and stop frequently, or even cause the compressor to shut down, which is very unfavorable to the reliability of the automobile system.
[0042] In order to solve the above problems, the utility model proposes a refrigeration system 100, which aims to solve the technical problem that the range of the exhaust return temperature of the compressor and the temperature of the evaporator in the existing automobile is limited by the flow rate and the compressor speed, which easily causes the compressor to start and stop frequently, or even cause the compressor to shut down, which is very unfavorable to the reliability of the automobile system.
[0043] See also Figures 1 to 3 , Figure 1 It is a structural schematic diagram of an implementation mode of the refrigeration system 100 of the utility model. Figure 2 It is a structural schematic diagram of another embodiment of the refrigeration system 100 of the utility model. Figure 3 It is a schematic diagram of a circuit function module of an implementation manner of the refrigeration system 100 of the utility model.
[0044] In the embodiment of the present utility model, the refrigeration system 100 is used in an automobile, and the automobile may include but is not limited to a fuel automobile, a pure electric automobile, a hybrid automobile, etc., and no specific limitation is made here.
[0045] See also Figure 1 and Figure 3, the refrigeration system 100 may include but is not limited to a compressor 1, a condenser 2 and a first evaporator 3. The exhaust port of the compressor 1 is connected to the input end of the condenser 2, the output end of the condenser 2 is connected to the input end of the first evaporator 3, and the output end of the first evaporator 3 is connected to the return air port of the compressor 1 through a return air pipe. That is, the compressor 1, the condenser 2 and the first evaporator 3 are connected in sequence through pipelines to form a first refrigeration cycle loop, and the refrigeration of the vehicle refrigerator is realized by using the first refrigeration cycle loop.
[0046] Specifically, the compressor 1 draws low-temperature and low-pressure refrigerant gas into the interior for compression through mechanical movement, thereby increasing its temperature and pressure; the compressed high-temperature and high-pressure refrigerant gas is conducted to the condenser 2 for heat dissipation, and the refrigerant gas after heat dissipation becomes a high-temperature and high-pressure liquid; after the high-temperature and high-pressure refrigerant liquid enters the first evaporator 3, it exchanges heat with the air in the box of the vehicle refrigerator, absorbs the heat in the box and conducts it to the compressor 1, thereby achieving the purpose of cooling.
[0047] Optionally, the first evaporator 3 may be implemented by a plate heat exchanger or an inflation heat exchanger, which is not specifically limited here.
[0048] For a better understanding, in the embodiments of the present invention, please refer to Figure 1 and Figure 3 The refrigeration system 100 further includes a heat preservation module 4 and a semiconductor refrigeration element 5. The heat preservation module 4 is installed in the box of the vehicle refrigerator, and the heat preservation module 4 forms a cavity 41. The semiconductor refrigeration element 5 is arranged in the cavity 41 of the heat preservation module 4, and is mainly used to absorb the heat in the cavity 41 of the heat preservation module 4. At the same time, based on the refrigeration effect of the first refrigeration cycle, the temperature in the box of the vehicle refrigerator is further reduced, and the refrigeration effect of the vehicle refrigerator is improved.
[0049] Optionally, the insulation module 4 can be made of a material with low thermal conductivity, such as an insulation foam layer, which mainly supports structures such as the semiconductor refrigeration component 5 in the cavity 41 and serves as a temperature barrier for structures outside the cavity 41.
[0050] Optionally, the semiconductor refrigeration element 5 can be implemented by a semiconductor refrigeration chip. The car refrigerator uses semiconductor chips for refrigeration, does not need to use any refrigerant, can work continuously, has no pollution source and rotating parts, and does not produce a rotation effect. The semiconductor refrigeration chip mainly uses the Peltier effect of the semiconductor. When direct current passes through a thermocouple formed by two different semiconductor materials in series, heat is absorbed and released at both ends of the thermocouple to achieve the purpose of refrigeration. That is, the two ends of the thermocouple of the semiconductor refrigeration chip form a cold end 52 and a hot end 51 respectively. The cold end 52 of the semiconductor refrigeration chip is used to absorb the heat in the cavity 41, so that the temperature in the cavity 41 can be continuously reduced to achieve the refrigeration of the car refrigerator.
[0051] According to the above content, in order to effectively control the return air temperature of the compressor 1, in the embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the first evaporator 3 is arranged toward the hot end 51 of the semiconductor refrigeration element 5, wherein the side of the first evaporator 3 facing the hot end 51 of the semiconductor refrigeration element 5 can be arranged adjacent to the hot end 51 of the semiconductor refrigeration element 5, or can be connected to the hot end 51 of the semiconductor refrigeration element 5, and the specific details are not limited here. In this arrangement, the hot end 51 of the semiconductor refrigeration element 5 can transfer the heat of the cold end 52 to the first evaporator 3, and the first evaporator 3 transfers the heat to the compressor 1, thereby increasing the return air temperature of the compressor 1, avoiding frequent start and stop of the compressor 1 during operation, or even shutdown, and effectively improving the reliability of the automobile system. At the same time, since the heat emitted by the hot end 51 of the semiconductor refrigeration element 5 is transferred to the compressor 1 by the first evaporator 3, that is, the heat emitted by the hot end 51 of the semiconductor refrigeration element 5 is further utilized, avoiding the heat from being wasted by diffusing outward, and can improve the refrigeration effect of the vehicle refrigerator.
[0052] In the technical solution of the utility model, the input end of the condenser 2 is connected with the exhaust port of the compressor 1, and the first evaporator 3 is connected with the output end of the condenser 2 and the return air port of the compressor 1, that is, the compressor 1, the condenser 2 and the first evaporator 3 are connected in sequence to form a first refrigeration cycle loop, and the refrigeration of the vehicle refrigerator is realized by using the first refrigeration cycle loop. On the basis of realizing the refrigeration function, a cavity 41 is formed by the heat preservation module 4, a semiconductor refrigeration component 5 is arranged in the cavity 41, and the hot end 51 of the semiconductor refrigeration component 5 is arranged toward the first evaporator 3, so that the hot end 51 of the semiconductor refrigeration component 5 transfers the heat of the hot end 51 to the first evaporator 3, and then transfers the heat to the compressor 1 by the first evaporator 3, thereby increasing the return air temperature of the compressor 1, avoiding frequent start and stop of the compressor 1 during operation, or even shutdown, and effectively improving the reliability of the automobile system.
[0053] Optionally, according to the above embodiment, the first evaporator 3 can be arranged in the cavity 41 of the heat preservation module 4, or can be arranged outside the cavity 41 of the heat preservation module 4. In order to improve the refrigeration effect of the vehicle refrigerator, in the embodiment of the utility model, please refer to Figure 1 , the first evaporator 3 is arranged in the cavity 41 of the heat preservation module 4, and is connected to the hot end 51 of the semiconductor refrigeration element 5, wherein the connection structure between the first evaporator 3 and the hot end 51 of the semiconductor refrigeration element 5 is not limited here. Through the above arrangement, the hot end 51 of the semiconductor refrigeration element 5 can quickly transfer the heat of the cold end 52 to the first evaporator 3, and then quickly transfer it to the compressor 1 through the first evaporator 3, thereby increasing the rising rate of the return air temperature of the compressor 1. At the same time, the first evaporator 3 can exchange heat with the air in the cavity 41 of the heat preservation module 4, absorb the heat in the cavity 41, and continuously reduce the temperature in the cavity 41, thereby improving the refrigeration effect of the vehicle refrigerator.
[0054] To further improve the cooling effect, in the embodiments of the present invention, please refer to Figure 1 The first evaporator 3 can be attached to the hot end 51 of the semiconductor refrigeration element 5 or attached through a heat-conducting medium. The heat-conducting medium can be a high thermal conductivity product such as thermal grease, thermal adhesive, or thermal paste.
[0055] In order to effectively control the return air temperature of the compressor 1, in the embodiment of the present utility model, please refer to Figure 1 and Figure 4 The refrigeration system 100 further includes a control component 7 and a first temperature detection component 6 electrically connected to the control component 7, a compressor 1, a condenser 2, a first evaporator 3 and a semiconductor refrigeration component 5. The first temperature detection component 6 can be implemented by a first temperature sensor. The first temperature detection component 6 is installed on the flow path between the return air port of the compressor 1 and the output end of the first evaporator 3, and is mainly used to detect the temperature of the refrigerant flowing back from the first evaporator 3 to the compressor 1, and output a corresponding first temperature signal to the control component 7.
[0056] Furthermore, the control component 7 determines the temperature value of the refrigerant returning from the first evaporator 3 to the compressor 1 according to the received first temperature signal, and compares the refrigerant temperature value with the preset temperature range; if the refrigerant temperature is less than the minimum value of the preset temperature range, it means that the return air temperature of the compressor 1 is low, and the control component 7 controls the semiconductor refrigeration component 5 to reduce the working voltage and reduce the cooling capacity so as to transfer more heat to the compressor 1 through the first evaporator 3, thereby increasing the return air temperature of the compressor 1 to within the preset temperature range; if the refrigerant temperature is greater than the maximum value of the preset temperature range, it means that the return air temperature of the compressor 1 is high, and the control component 7 controls the semiconductor refrigeration component 5 to increase the working voltage and increase the cooling capacity so as to transfer less heat to the compressor 1 through the first evaporator 3, thereby reducing the return air temperature of the compressor 1 to within the preset temperature range.
[0057] In the embodiments of the present invention, please refer to Figure 4 , the control component 7 is also used to detect the operating state of the compressor 1, and adjust the voltage of the semiconductor refrigeration element 5 according to the operating state of the compressor 1. For example, when the control component 7 detects that the operating state of the compressor 1 is in the shutdown state, that is, when the first refrigeration cycle stops running, the compressor 1 will be in a low temperature state due to the stop of the first refrigeration cycle. To improve this situation, the control component 7 will control the semiconductor refrigeration element 5 to reduce the working voltage and reduce the cooling capacity, so as to transfer more heat to the compressor 1 through the first evaporator 3, so that the return air temperature of the compressor 1 is increased to within the preset temperature range.
[0058] In order to achieve the cooling of the power supply device of the automobile, in the embodiment of the utility model, please refer to Figure 1 and Figure 4 The refrigeration system 100 further includes a second evaporator 8. Optionally, the second evaporator 8 can be implemented by a plate heat exchanger or an inflation heat exchanger, which is not limited here. The second evaporator 8 is used to be installed in the housing of the power supply device of the automobile, and is used to exchange with the air in the housing, absorb the heat in the housing to cool the housing.
[0059] Specifically, the input end of the second evaporator 8 is connected to the output end of the condenser 2, and the output end of the second evaporator 8 is connected to the return air port of the compressor 1. That is, the compressor 1, the condenser 2 and the second evaporator 8 are connected by pipelines to form a second refrigeration cycle loop, and the second refrigeration cycle loop is used to cool the power supply device of the car. The compressor 1 draws low-temperature and low-pressure refrigerant gas into the interior for compression through mechanical movement, so that its temperature and pressure increase; the high-temperature and high-pressure refrigerant gas after compression is conducted to the condenser 2 for heat dissipation, and the refrigerant gas after heat dissipation becomes a high-temperature and high-pressure liquid; after the high-temperature and high-pressure refrigerant liquid enters the second evaporator 8, it exchanges heat with the air in the shell of the power supply device, absorbs the heat in the shell and conducts it to the compressor 1, thereby reducing the temperature in the shell and extending the service life of the battery in the shell.
[0060] Similarly, in order to achieve cooling of the entire vehicle, in the embodiment of the present utility model, please refer to Figure 1 and Figure 4 The refrigeration system 100 further includes a third evaporator 9. The third evaporator 9 can be implemented by a plate heat exchanger or an inflation heat exchanger, which is not limited here. The third evaporator 9 is used to be installed in the car, and is mainly used to exchange with the air in the car, absorb the heat in the car to cool the car.
[0061] Specifically, the input end of the third evaporator 9 is connected to the output end of the condenser 2, and the output end of the third evaporator 9 is connected to the return air port of the compressor 1. That is, the compressor 1, the condenser 2 and the third evaporator 9 are connected by pipelines to form a third refrigeration cycle loop, and the third refrigeration cycle loop is used to achieve cooling in the car. The compressor 1 draws low-temperature and low-pressure refrigerant gas into the interior for compression through mechanical movement, so that its temperature and pressure increase; the high-temperature and high-pressure refrigerant gas after compression is conducted to the condenser 2 for heat dissipation, and the refrigerant gas after heat dissipation becomes a high-temperature and high-pressure liquid; after the high-temperature and high-pressure refrigerant liquid enters the third evaporator 9, it exchanges heat with the air in the car, absorbs the heat in the car and conducts it to the compressor 1, thereby reducing the temperature in the car.

In this way, the connecting pipes between the second evaporator 8 and the third evaporator 9 and the condenser 2 can be reduced, and the connecting pipes between the second evaporator 8 and the third evaporator 9 and the compressor 1 can be reduced, effectively reducing the volume of the refrigeration system 100, making it easier to install it in a car.

[0064] In an embodiment of the utility model, the input ends of the first evaporator 3, the second evaporator 8 and the third evaporator 9 are respectively provided with flow regulating components 10. The flow regulating component 10 can be implemented by a flow regulating valve. The flow regulating valve is electrically connected to the control component 7 of the refrigeration system 100. The control component 7 is used to control the flow regulating valve to adjust the refrigerant flow from the condenser 2 to the corresponding evaporator according to the working condition of the automobile. For example, the control component 7 selectively controls the flow regulating valve arranged at the input end of the first evaporator 3 to adjust the refrigerant flow from the condenser 2 to the first evaporator 3 according to the working condition of the automobile, so that the efficiency of the refrigeration system 100 is always maximized and the energy consumption of the refrigeration system 100 is reduced.
