[0037] With the improvement of living standards, more and more cars are equipped with refrigeration function modules (such as car refrigerators, car ice makers, etc.) to meet the needs of users to enjoy cold drinks at any time while traveling or outdoors. Taking car refrigerators as an example, most car refrigerators are currently driven by compressors. When the car is parked, in order to ensure the normal operation of the refrigeration function of the car refrigerator, it is necessary to drive the compressor separately to deliver cold air to the car refrigerator, which will result in higher fuel consumption and louder noise.
[0038] The utility model provides a refrigeration system 100, which aims to realize the refrigeration function of the refrigeration function module 50 when the car is parked without starting the compressor 10 separately, so as to reduce fuel consumption and noise.
[0039] See also Figures 1 to 3 In one embodiment of the utility model, the refrigeration system 100 includes a compressor 10, a condenser 20, a cold storage module 30 and a refrigeration function module 50. The input end of the condenser 20 is connected to the exhaust port 11 of the compressor 10; the cold storage module 30 includes a heat preservation container 31, and a first evaporator 32 and a cold storage medium 33 arranged in the heat preservation container 31, and the first evaporator 32 connects the output end of the condenser 20 with the return air port 12 of the compressor 10; the refrigeration function module 50 cooperates with the cold storage medium 33 in heat conduction, and the cold storage medium 33 is used to transfer cold to the refrigeration function module 50.
[0040] It can be understood that the compressor 10, the condenser 20 and the first evaporator 32 are connected to form a refrigerant circulation flow path, and a throttling component is usually provided between the condenser 20 and the first evaporator 32. When the compressor 10 is running, the high-temperature and high-pressure gaseous refrigerant discharged from the exhaust port 11 of the compressor 10 is transported to the condenser 20 for heat exchange, and the medium-temperature and high-pressure liquid refrigerant output by the condenser 20 is throttled and depressurized by the throttling component to become a low-temperature and low-pressure liquid condensation, and the low-temperature and low-pressure liquid refrigerant is transported to the first evaporator 32 for heat exchange, and the evaporator outputs a low-temperature and low-pressure gaseous refrigerant and flows back into the compressor 10 through the return port 12 of the compressor 10, thereby completing a refrigeration cycle. In the entire refrigeration cycle, heat can be dissipated to the external environment through the condenser 20, and cold can be dissipated to the external environment through the first evaporator 32. It is worth noting that the compressor 10 can be a compressor 10 configured separately by the refrigeration function module 50, or it can be a compressor 10 shared by the refrigeration module and the thermal management system of the car (such as air conditioning, battery, etc.).
[0041] The technical solution of the utility model forms a refrigerant circulation flow path by connecting the compressor 10, the condenser 20 and the first evaporator 32, and the first evaporator 32 and the cold storage medium 33 are both arranged in the heat preservation container 31. When the compressor 10 is running, the first evaporator 32 can emit cold energy to the cold storage medium 33, and the cold energy can be stored by the cold storage medium 33. Since the refrigeration function module 50 cooperates with the cold storage medium 33 in heat conduction, when the compressor 10 stops running, the stored cold energy can be transferred to the refrigeration function module 50 through the cold storage medium 33 to continuously cool down or keep warm the refrigeration function, so that the refrigeration function module 50 maintains the refrigeration function. When the refrigeration system 100 is applied to a car, when the car is parked, the refrigeration function of the refrigeration function module 50 can be realized without starting the compressor 10 separately, so as to reduce fuel consumption and noise.
[0042] It is worth noting that there are many ways for the refrigeration function module 50 to cooperate with the cold storage medium 33 in heat conduction.
[0043] For example, Figure 1 As shown, in one embodiment, the refrigeration function module 50 is in contact with the cold storage medium 33 for heat conduction. In this way, the cold storage medium 33 can directly transfer cold energy to the refrigeration function module 50 to cool down the refrigeration function module 50. Optionally, the refrigeration function module 50 includes a semiconductor refrigeration element 52 and a hot end radiator 54 provided at the hot end of the semiconductor refrigeration element 52, and the hot end radiator 54 is at least partially located in the heat preservation container 31 and directly in contact with the cold storage medium 33.
[0044] For example, Figure 4 As shown, in another embodiment, the refrigeration function module 50 has a refrigeration chamber 511, and the cold storage medium 33 transfers cold to the refrigeration chamber 511 through the heat conductive element 90. For example, the heat conductive element 90 can be embedded in the side wall of the refrigeration chamber 511, one side of the heat conductive element 50 is in contact with the refrigeration chamber 511, and the other side of the heat conductive element 50 is in contact with the cold storage medium 33. In this way, the heat conductive element 90 can transfer the cold stored in the cold storage medium 33 to the refrigeration chamber 511, thereby realizing the refrigeration function of the refrigeration function module 50. Among them, the heat conductive element 90 includes but is not limited to being made of materials with good thermal conductivity such as aluminum and copper.
[0045] For example, Figure 5As shown, in another embodiment, the refrigeration function module 50 includes a refrigerator body 51 and a semiconductor refrigeration element 52, the refrigerator body 51 has a refrigeration chamber 511, the semiconductor refrigeration element 52 is arranged on the refrigerator body 51, the cold end of the semiconductor refrigeration element 52 is used to cool the refrigeration chamber 511, the cold storage medium 33 exchanges heat with the hot end of the semiconductor refrigeration element 52, and the cold storage medium 33 also transfers the cold to the refrigeration chamber 511 through the heat conducting element 90.
[0046] In this embodiment, the refrigeration function module 50 specifically relates to a semiconductor refrigeration refrigerator. When the semiconductor refrigeration element 52 is working, the cold energy is dissipated into the refrigeration chamber 511 through the cold end of the semiconductor refrigeration element 52, and the hot end of the semiconductor refrigeration element 52 can be dissipated through the cold storage medium 33; in addition, the cold energy can also be directly transferred to the refrigeration chamber 511 through the heat conduction element 90 through the cold storage medium 33 to further cool the refrigeration chamber 511. In this way, the refrigeration effect of the refrigeration function module 50 can be further improved through multiple cooling effects. In some scenarios, even if the semiconductor refrigeration element 52 is not working, the cold energy can be directly transferred to the refrigeration chamber 511 through the cold storage medium 33 through the heat conduction element 90 to cool the refrigeration chamber 511, so that the refrigeration function module 50 can achieve the refrigeration function.
[0047] Among them, the cold storage medium 33 can absorb and store a large amount of cold at low temperatures, and can release a large amount of cold at higher temperatures. The cold storage medium 33 can be liquid, solid, or a solid-liquid mixture. Optionally, the cold storage medium 33 is a cold storage liquid. For example, the cold storage medium can be water, salt water, or ethylene glycol solution. For another example, the cold storage medium can also be a eutectic salt, and the eutectic salt cold storage medium is mainly a mixture of inorganic salts, water, nucleating agents, and stabilizers.
[0048] The amount of the cold storage medium 33 is related to its expansion coefficient. Usually, the cold storage medium 33 will expand when frozen. In order to avoid bursting the thermal insulation container 31, optionally, the volume of the cold storage medium 33 in the thermal insulation container 31 does not exceed 95% of the volume of the thermal insulation container 31.
[0049] In order to prevent the thermal expansion and contraction of the cold storage medium 33 from causing the thermal insulation container 31 to expand or contract, Figure 2 As shown, in one embodiment, the heat preservation container 31 is provided with a pressure relief port, and the cold storage module 30 further includes a pressure relief valve 34 provided at the pressure relief port. When the pressure in the heat preservation container 31 is too high or too low, the pressure relief valve 34 can be opened to balance the heat preservation container 31 with the external pressure.
[0050] Please refer to Figure 1 and Figure 3In one embodiment, the refrigeration function module 50 includes a refrigerator body 51 and a semiconductor refrigeration component 52 arranged on the refrigerator body 51, the refrigerator body 51 has a refrigeration chamber 511, the cold end of the semiconductor refrigeration component 52 is used to cool the refrigeration chamber 511, and the hot end of the semiconductor refrigeration component 52 is used to exchange heat with the cold storage medium 33.
[0051] In this embodiment, the refrigeration function module 50 is a refrigerator, specifically a vehicle-mounted refrigerator with a semiconductor refrigeration function, and the refrigeration function module 50 includes a refrigerator body 51 and a semiconductor refrigeration component 52. Among them, the semiconductor refrigeration component 52 can be specifically a semiconductor refrigeration chip, which mainly uses the Peltier effect of semiconductors. When direct current passes through a thermocouple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple respectively, so as to achieve the purpose of refrigeration. When the compressor 10 of the refrigeration system 100 is running, the first evaporator 32 is used to cool the cold storage medium 33, and the hot end of the semiconductor refrigeration component 52 is cooled by the cold storage medium 33. Further, the cold end of the semiconductor refrigeration component 52 is used to cool the refrigeration chamber 511. And when the compressor 10 stops running, the cold amount stored in the cold storage medium 33 can be continuously transferred to the hot end of the semiconductor refrigeration component 52 to cool the hot end of the semiconductor refrigeration component 52. Since the semiconductor refrigeration element 52 itself has refrigeration capacity, and the semiconductor hot end is dissipated by the cold storage medium 33, the cold end of the semiconductor refrigeration element 52 has a lower temperature, thereby meeting the need for the refrigeration chamber to reach a lower temperature, and the temperature range that can be controlled is wider. For example, the low temperature of the first evaporator 32 can be about 10°C. When the refrigeration chamber 511 needs a lower temperature, the voltage at both ends of the semiconductor refrigeration element 52 can be increased so that the cold end of the semiconductor refrigeration element 52 can obtain a temperature that is more than 20°C lower than the cold storage medium.
[0052] It is understandable that when the refrigeration function module 50 and the air conditioning system of the car share a set of compressors 10, the low temperature required by the air conditioning system and the refrigerator system is different. If the refrigeration function module 50 (such as a refrigerator) wants to achieve a lower low temperature, it is necessary to perform more complex control on the system. In this technical solution, since the semiconductor refrigeration element 52 itself has refrigeration capacity, and the heat is dissipated from the hot end of the semiconductor through the cold storage medium 33, the cold end of the semiconductor refrigeration element 52 has a lower low temperature, so that the refrigerator temperature can be further reduced, and the complexity of the original automobile air conditioning system will not be increased, the control logic is simpler, and the system reliability is higher.
[0053] Furthermore, in one embodiment, the refrigerator body 51 includes a thermal insulation layer 512 surrounding the outer periphery of the refrigeration chamber 511, the semiconductor refrigeration element 52 is arranged in the thermal insulation layer 512, and the thermal insulation layer 512 is provided with a heat dissipation port opposite to the cold end of the semiconductor refrigeration element 52 on one side close to the refrigeration chamber 511, and the thermal insulation layer 512 is provided with a heat dissipation port opposite to the hot end of the semiconductor refrigeration element 52 on one side close to the thermal insulation container 31.
[0054] In this embodiment, the thermal insulation layer 512 is arranged around the periphery of the refrigeration chamber 511. The thermal insulation layer 512 can reduce the cold dissipation in the refrigeration chamber 511, so that the refrigeration chamber 511 can maintain a relatively low temperature. The side wall of the thermal insulation layer 512 close to the cold storage module 30 is provided with a cavity for accommodating the semiconductor refrigeration element 52. The two ends of the cavity respectively penetrate the inner and outer surfaces of the thermal insulation layer 512 to form a cold dissipation port and a heat dissipation port. The cold generated by the cold end of the semiconductor refrigeration element 52 can be dissipated into the refrigeration chamber 511 through the cold dissipation port to cool the refrigeration chamber 511. The heat generated by the hot end of the semiconductor refrigeration element 52 can be heat exchanged with the cold storage medium 33 in the heat preservation container 31 through the heat dissipation port, thereby achieving the cooling of the hot end of the semiconductor refrigeration element 52.
[0055] In order to further enhance the heat exchange effect between the semiconductor refrigeration element 52 and the refrigeration chamber 511, in one embodiment, the refrigeration function module 50 further includes a cold end radiator 53 disposed at the cooling port, and the cold end radiator 53 is at least partially located in the refrigeration chamber 511. In this way, the coldness of the cold end of the semiconductor refrigeration element 52 can be more efficiently radiated to the refrigeration chamber 511 through the cold end radiator 53, thereby facilitating rapid reduction of the temperature in the refrigeration chamber 511. The cold end radiator 53 can be a cooling fan for blowing the coldness to the refrigeration chamber 511.
[0056] In order to further enhance the heat exchange effect between the semiconductor refrigeration element 52 and the cold storage medium 33 in the thermal insulation container 31, in one embodiment, the refrigeration function module 50 further includes a hot end radiator 54 disposed at the heat dissipation port, and the hot end radiator 54 is at least partially located in the thermal insulation container 31. In this way, the heat at the hot end of the semiconductor refrigeration element 52 can be more efficiently dissipated into the thermal insulation container 31 through the hot end radiator 54, thereby performing a more efficient heat exchange with the cold storage medium 33 in the thermal insulation container 31. The hot end radiator 54 can be a heat dissipation fan for blowing heat toward the thermal insulation container 31.
[0057] In order to simultaneously enhance the heat exchange effect between the semiconductor refrigeration element 52 and the refrigeration chamber 511 and the cold storage medium 33 in the heat preservation container 31, optionally, as Figure 1 and Figure 3As shown, the refrigeration function module 50 also includes a cold-end radiator 53 disposed at the cooling outlet, and a hot-end radiator 54 disposed at the cooling outlet, wherein the cold-end radiator 53 is at least partially located in the refrigeration chamber 511 , and the hot-end radiator 54 is at least partially located in the heat preservation container 31 .

The heat conducting member 55 may be a heat conducting aluminum brick.

Among them, the second evaporator 60 can be an air conditioning evaporator of a car, or a battery cooling evaporator for cooling a car battery, and of course, it can also be an evaporator for realizing other refrigeration functions.
[0061] Furthermore, if Figure 1 As shown, in one embodiment, the refrigeration system 100 further includes a third evaporator 70 , and the third evaporator 70 connects the output end of the condenser 20 with the return air port 12 of the compressor 10 .
[0062] In this embodiment, the third evaporator 70 can be connected in parallel or in series with the first evaporator 32 and the second evaporator 60 between the output end of the condenser 20 and the return air port 12 of the compressor 10. The first evaporator 32, the second evaporator 60 and the third evaporator 70 share a set of compressors 10, which is conducive to reducing costs and reducing the volume of the entire refrigeration system 100. Among them, the second evaporator 60 can be an air conditioning evaporator of the car, and the third evaporator 70 can be a battery cooling evaporator for cooling the car battery. Of course, the second evaporator 60 and the third evaporator 70 can also be evaporators for realizing other refrigeration functions.
[0063] There are various arrangements of the first evaporator 32, the second evaporator 60, and the third evaporator 70. For example, the first evaporator 32, the second evaporator 60, and the third evaporator 70 are arranged in parallel. For another example, the first evaporator 32, the second evaporator 60, and the third evaporator 70 are arranged in series. For another example, two of the first evaporator 32, the second evaporator 60, and the third evaporator 70 are arranged in series and in parallel with the other one.
[0064] Furthermore, if Figure 1 As shown, in one embodiment, the output end of the condenser 20 is connected to the first evaporator 32 through a first branch, and the first branch is provided with a first flow regulating member 41. The flow regulation of the first branch can be achieved through the first flow regulating member 41, thereby controlling the flow of the refrigerant input to the first evaporator 32. The first flow regulating member 41 can be a flow regulating valve or an on-off valve.
[0065] Furthermore, if Figure 1 As shown, in one embodiment, the output end of the condenser 20 is connected to the second evaporator 60 through a second branch, and the second branch is provided with a second flow regulating member 42.
