Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigeration equipment, in particular to a split-type vehicle-mounted refrigerator. Background Art

[0002] In recent years, with the popularity of new energy vehicles, people's requirements for the comfort and functionality of cars are constantly increasing. Car refrigerators can add refrigeration and heat preservation functions to cars. The refrigeration system of common car refrigerators generally includes a compressor, a condenser and an evaporator. The evaporator is used to cool the inside of the refrigerator, while the power cords of the compressor and condenser are connected to the battery system of the car through electrical connectors for cooling.

[0003] In outdoor use scenarios, users would like to be able to take the car refrigerator out of the car and carry it with them. However, existing car refrigerators basically integrate the refrigeration system inside the refrigerator. Considering that the compressor, condenser and other parts are heavy and take up space, the portability of car refrigerators is relatively poor. Utility Model Content

[0004] The utility model aims to solve the problem that the vehicle-mounted refrigerator in the prior art has a large weight and volume and relatively poor portability due to the refrigeration system being integrated inside the refrigerator.

[0005] To solve the above problems, the utility model provides a split-type vehicle-mounted refrigerator, comprising a refrigeration system and a cold delivery system, and a refrigeration bin and a cold storage bin detachably connected to each other, wherein the refrigeration system at least comprises a condenser, an evaporator, a compressor and a refrigeration pipeline, wherein the refrigeration pipeline comprises a first refrigeration pipeline section from the compressor to the evaporator and a second refrigeration pipeline section from the evaporator to the compressor, and the condenser is connected to the first refrigeration pipeline section; the cold delivery system comprises a liquid cooling box, a heat exchanger, a pump body, a switch component and a cold delivery pipeline, wherein the cold delivery pipeline comprises a first cold delivery pipeline section from the liquid cooling box to the heat exchanger and a second cold delivery pipeline section from the heat exchanger to the liquid cooling box, wherein the evaporator is connected to the first cold delivery pipeline section, the pump body is connected to the second cold delivery pipeline section, and the switch component is used to control the on / off of the portion of the first cold delivery pipeline section located in the refrigeration bin;

[0006] Among them, the liquid cooling box, pump body, switch components and refrigeration system of the cold delivery system are all installed in the refrigeration warehouse, the heat exchanger of the cold delivery system is installed in the cold storage warehouse, the part of the first cold delivery pipe section located in the refrigeration warehouse is connected to the part located in the cold storage warehouse through a first detachable pipe joint, and the part of the second cold delivery pipe section located in the refrigeration warehouse is connected to the part located in the cold storage warehouse through a second detachable pipe joint.

[0007] In the above scheme, the cold storage compartment is used for refrigerating goods, and the refrigerating compartment is powered by a car power supply; compared with the prior art, the above scheme designs a refrigeration system and a cold delivery system separately, wherein the compressor, the first refrigeration pipeline, the evaporator, and the second refrigeration pipeline of the refrigeration system form a circulating refrigeration loop, and the liquid cooling box, the first cold delivery pipeline, the heat exchanger, and the second cold delivery pipeline of the cold delivery system form a circulating cold delivery loop; and the evaporator is not only connected to the compressor through the refrigeration pipeline to form a loop, but also connected to the first cold delivery pipeline section of the cold delivery system, so that the medium in the first cold delivery pipeline section can receive the cold output by the refrigeration system through the evaporator, and transport the cold to the heat exchanger in the cold storage compartment, so as to achieve cooling in the cold storage compartment, and then the medium in the heat exchanger flows back to the liquid cooling box through the pump body of the second cold delivery pipeline section, and the liquid cooling box continues to provide medium to the first cold delivery pipeline section, That is, the circulation cooling of the cold storage compartment is realized; and when the cold storage compartment needs to be taken out, the part of the first cold supply pipe section located in the cold storage compartment is first blocked by the switch component, and the pump body continues to work until the part of the first cold supply pipe section located in the cold storage compartment, the part of the second cold supply pipe section located in the cold storage compartment and the medium in the heat exchanger are all returned to the liquid cooling box. At this time, by disassembling the first detachable pipe joint and the second detachable pipe joint respectively, and separating the cold storage compartment from the refrigerating compartment, the refrigerating compartment can be taken out independently and carried. Since the heavy refrigeration system and the liquid cooling box, pump body, and switch component of the cold supply system are all located in the refrigerating compartment, and there is only a heat exchanger in the refrigerating compartment, the portable refrigerating compartment is lighter in weight and less space is occupied, and the portability is good; of course, the refrigerating compartment and the cold storage compartment can also be taken out of the car together as needed, and the refrigerating compartment can be powered by other external power sources at this time.

[0008] In an improved solution, the first detachable pipe joint and the second detachable pipe joint are both arranged on opposite sides of the refrigerating compartment and the cold storage compartment, so that the overall structure is more compact, and the first detachable pipe joint and the second detachable pipe joint can be disassembled only after the cold storage compartment and the refrigerating compartment are separated, thereby reducing the problem of leakage of the first detachable pipe joint and the second detachable pipe joint due to collision.

[0009] In an improved solution, the heat exchanger is located at the upper part of the refrigerated compartment, which is beneficial to improving the heat exchange efficiency in the refrigerated compartment.

[0010] In an improved solution, the switch component is connected to the portion of the first cold supply pipe section located in the refrigeration warehouse and is located between the evaporator and the first detachable pipe joint, thereby ensuring that after the switch component blocks the first cold supply pipe section, no medium will flow from the first detachable pipe joint to the refrigeration warehouse.

[0011] In an improved solution, the switch element is connected to the portion of the first cold transport pipe section located in the refrigeration compartment and is located between the evaporator and the liquid cooling tank.

[0012] In an improved solution, the switch element is a solenoid valve, so that the switch element can be controlled to be on and off by an electrical signal.

[0013] In an improved solution, the first refrigeration pipe section is connected to the evaporator via a capillary tube.

[0014] In an improved solution, the refrigeration system further includes a filter, which is arranged in the first refrigeration pipe section and located between the condenser and the capillary tube, thereby ensuring that the medium in the first refrigeration pipe section is filtered by the filter before flowing into the capillary tube to avoid blockage.

[0015] In an improved solution, the medium in the refrigeration pipeline is a high-pressure refrigerant, and the medium in the cold delivery pipeline is a normal-pressure liquid. Since the high-pressure refrigerant flowing in the refrigeration system is very easy to leak, and it is impossible to achieve quick plug-in and disconnection without leakage, this solution also designs a cold delivery system, and the flowing medium in the cold delivery pipeline is a normal-pressure liquid, which is easy to achieve quick plug-in and disconnection at low cost, and is not easy to leak.

[0023] See also Figure 1 The embodiment of the utility model provides a split-type vehicle refrigerator, comprising a refrigeration system and a cold delivery system, and a refrigeration compartment 1 and a cold storage compartment 2 that are detachably connected to each other, the refrigeration system at least comprising a condenser 31, an evaporator 32, a compressor 33 and a refrigeration pipeline 4, the refrigeration pipeline 4 comprising a first refrigeration pipeline section 41 from the compressor 33 to the evaporator 32 and a second refrigeration pipeline section 42 from the evaporator 32 to the compressor 33, the condenser 31 is connected to the first refrigeration pipeline section 41; the cold delivery system comprises a liquid cooling box 51, a heat exchanger 52, a pump body 53, a switch 54 and a cold delivery pipeline 6, the cold delivery pipeline 6 comprising a first cold delivery pipeline section 61 from the liquid cooling box 51 to the heat exchanger 52 and a second cold delivery pipeline section 62 from the heat exchanger 52 to the liquid cooling box 51, the evaporator 32 is connected to the first cold delivery pipeline section 61, the pump body 53 is connected to the second cold delivery pipeline section 62, and the switch 54 is used to control the on-off of the part of the first cold delivery pipeline section 61 located in the refrigeration compartment 1;

[0024] Among them, the liquid cooling box 51, pump body 53, switch component 54 and refrigeration system of the cold delivery system are all installed in the refrigeration warehouse 1, the heat exchanger 52 of the cold delivery system is installed in the cold storage warehouse 2, the part of the first cold delivery pipe section 61 located in the refrigeration warehouse 1 and the part located in the cold storage warehouse 2 are connected through a first detachable pipe joint 63, and the part of the second cold delivery pipe section 62 located in the refrigeration warehouse 1 and the part located in the cold storage warehouse 2 are connected through a second detachable pipe joint 64.

[0025] In the above scheme, the cold storage compartment 2 is used for refrigerating goods, and the cold storage compartment 1 is powered by a car power supply; compared with the prior art, the above scheme is designed by separately designing a refrigeration system and a cold delivery system, wherein the compressor 33, the first refrigeration pipeline 4, the evaporator 32, and the second refrigeration pipeline 4 of the refrigeration system form a circulating refrigeration loop, and the liquid cooling box 51, the first cold delivery pipeline 6, the heat exchanger 52, and the second cold delivery pipeline 6 of the cold delivery system form a circulating cold delivery loop; and the evaporator 32 is not only connected to the compressor 33 through the refrigeration pipeline 4 to form a loop, but also connected to the first cold delivery pipe section 61 of the cold delivery system, so that the medium in the first cold delivery pipe section 61 can receive the cold output of the refrigeration system through the evaporator 32, and the cold is delivered to the heat exchanger 52 in the cold storage compartment 2, so as to achieve cooling in the cold storage compartment 2, and then the medium in the heat exchanger 52 is refluxed to the liquid cooling box 51 through the pump body 53 of the second cold delivery pipe section 62, and the liquid cooling box 51 continues to provide medium to the first cold delivery pipe section 61 When the refrigerated warehouse 2 needs to be taken out, the part of the first cold delivery pipe section 61 located in the refrigerated warehouse 1 is first blocked by the switch member 54, and the pump body 53 continues to work until the part of the first cold delivery pipe section 61 located in the refrigerated warehouse 2, the part of the second cold delivery pipe section 62 located in the refrigerated warehouse 2 and the medium in the heat exchanger 52 are all returned to the liquid cooling tank 51. At this time, the first detachable pipe joint 63 and the second detachable pipe joint 64 are respectively disassembled, and the refrigerated warehouse 2 is separated from the refrigerated warehouse 1, and the refrigerated warehouse 2 can be taken out and carried independently. Since the heavy refrigeration system and the liquid cooling tank 51, pump body 53, and switch member 54 of the cold delivery system are all located in the refrigerated warehouse 1, and there is only the heat exchanger 52 in the refrigerated warehouse 2, the refrigerated warehouse 2 for carrying is light in weight and less space is occupied, and the portability is good; of course, the refrigerated warehouse 1 and the refrigerated warehouse 2 can also be taken out of the car together as needed, and the refrigerated warehouse 1 can be powered by other external power sources.

[0026] It should be noted that the present design does not limit the specific form of the detachable connection between the cold storage compartment 2 and the refrigerating compartment 1. For example, a hook may be provided on the outer wall of the cold storage compartment 2, and a slot may be provided on the outer wall of the refrigerating compartment 1, so that the cold storage compartment 2 and the refrigerating compartment 1 can be quickly disassembled and assembled by snap-fitting; or screw holes may be provided on the cold storage compartment 2 and the refrigerating compartment 1, so that the cold storage compartment 2 and the refrigerating compartment 1 can be quickly disassembled and assembled by bolts.

[0027] In the present embodiment, the first detachable pipe joint 63 and the second detachable pipe joint 64 are both lever-type quick-release pipe joints or screw-type quick-release pipe joints, and of course, they can also be other forms of quick-release pipe joints in the prior art, and the specific form is not limited in this design; the first detachable pipe joint 63 and the second detachable pipe joint 64 are preferably arranged on opposite sides of the refrigerating warehouse 1 and the cold storage warehouse 2, so that the overall structure is more compact, and the first detachable pipe joint 63 and the second detachable pipe joint 64 can only be disassembled after the cold storage warehouse 2 is detached from the refrigerating warehouse 1, thereby reducing the probability of leakage of the first detachable pipe joint 63 and the second detachable pipe joint 64 due to collision.

[0028] In this embodiment, the heat exchanger 52 is fixedly installed on the upper part of the refrigerating chamber 2, so as to improve the heat exchange efficiency in the refrigerating chamber 2. The heat exchanger 52 is preferably a fin-type structure with high heat exchange efficiency.

[0029] In this embodiment, the first refrigeration pipe section 41 is connected to the evaporator 32 through the capillary tube 34. The medium in the first refrigeration pipe section 41 enters the evaporator 32 from the capillary tube 34, and is depressurized and expanded, absorbing heat, thereby achieving cooling of the evaporator 32. Of course, the first refrigeration pipe section 41 and the evaporator 32 may also be connected through an expansion valve, that is, the expansion valve is used to achieve depressurization and expansion of the medium entering the evaporator 32. Furthermore, the refrigeration system further includes a filter 35, which is disposed in the first refrigeration pipe section 41 and is located between the condenser 31 and the capillary tube 34, thereby ensuring that the medium in the first refrigeration pipe section 41 is filtered by the filter 35 before flowing into the capillary tube 34 to avoid blockage.
