Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigerators, in particular to a condenser in a vehicle-mounted refrigerator. Background Art

[0002] With the development of social economy and automobile industry, the grade of automobiles has gradually improved. Many cars are equipped with car refrigerators to provide passengers with cool drinks or fresh food during the journey. Car refrigerators are a common type of car electrical appliances. They are installed in the car when in use, or taken out for outdoor use. In car refrigerators, compressors and condensers are generally used for refrigeration.

[0003] In existing car refrigerators, in addition to the condenser, a fan for dissipating heat from the condenser is usually installed, so space needs to be reserved for installing the fan. Due to the limited interior space of some car models, the space left for the car refrigerator is not large. As a result, there are too many internal structural elements in the car refrigerator, resulting in the car refrigerator itself being too large, which in turn affects the user's use and activity space in the car, thereby reducing the user's experience.

[0023] As Figures 1 to 4 shown, this utility model provides a condenser inside a vehicle-mounted refrigerator, which includes a box body 1. Inside the box body 1, a control area 2 and a refrigeration area 3 are respectively provided. A compressor 4 for exporting and recycling refrigerant is fixedly installed in the control area 2. The compressor 4 extends towards the refrigeration area 3 and is connected with a condenser 5 for heat dissipation. Specifically, the condenser 5 extends into the refrigeration area 3 and is attached to at least three inner wall surfaces of the box body 1.

[0024] The condenser 5 is bent and arranged on the inner wall of the box body 1 to form a circulating U-shaped line structure.

[0025] The box body 1 is made of sheet metal heat-conducting material.

[0026] An inner container 8 for placing refrigerated items is provided in the refrigeration area 3. Specifically, an evaporator 10 for refrigeration is evenly arranged around the outer wall of the inner container 8.

[0027] The first end of the condenser 5 is connected with the compressor 4 through an air outlet pipe 6. A drying filter 11 for filtering out impurities and moisture is connected to the end of the condenser 5. The other end of the drying filter 11 is connected with the first end of the evaporator 10 through a capillary tube 12 for throttling. The pipe diameter of the capillary tube 12 is smaller than the pipe diameters of the condenser 5 and the evaporator 10.

[0028] The end of the evaporator 10 is connected to the compressor 4 through a return air pipe 7.

[0029] A cover plate 9 is provided at the top of the box body 1.

[0030] The refrigeration principle of the present utility model is as follows: The compressor 4 compresses the refrigerant with low temperature and low pressure into high-temperature and high-pressure steam, and transports the high-temperature and high-pressure refrigerant steam to the condenser 5 through the air outlet pipe 6. The compressed high-temperature and high-pressure refrigerant steam releases heat in the condenser 5 and gradually cools and transforms into a high-pressure and medium-temperature liquid. Since the pipeline of the condenser 5 is directly arranged and attached to the inner wall of the box body 1, and the wall of the box body 1 is made of a heat-conducting material, the heat generated when the refrigerant transforms from a gaseous state to a liquid state is directly dissipated to the outside through the inner wall of the box body 1;

[0031] The liquid refrigerant enters the capillary tube 12 after being filtered to remove moisture and impurities through a drying filter 11. Due to the small diameter of the capillary tube 12, part of the refrigerant that has not been completely transformed into a liquid state enters a completely liquid state after passing through the capillary tube 12;

[0032] The liquid refrigerant then enters the evaporator 10. Since the diameter of the evaporator 10 becomes larger, the refrigerant enters a flashing point state at the moment of entering the evaporator 10. At this time, the refrigerant rapidly changes from a liquid state to a gaseous state. A large amount of heat is required for the refrigerant to transform during this process, so a large amount of heat from the outside is absorbed. At this time, the evaporator 10 consumes a large amount of heat and thus rapidly cools down. The air is cooled to a low temperature after passing through the evaporator 10, thereby cooling the items in the inner container 8 of the refrigerated area 3 to achieve the refrigeration effect;

[0033] Finally, after the liquid refrigerant is discharged from the evaporator 10, it is transported back to the compressor 4 through the return air pipe 7 for the next cycle.

[0034] The electrical connections inside the compressor 4 and other electrical components are common and easily conceivable technical means for those skilled in the art, so they will not be elaborated here.

[0035] The advantages of the present utility model are as follows: By canceling the existing fan for dissipating heat from the condenser 5, the pipeline of the condenser 5 is directly arranged and attached to the inner wall of the box body 1, and the box body 1 made of a heat-conducting material directly dissipates heat from the condenser 5 to achieve the refrigeration effect, reducing the structural components inside the vehicle-mounted refrigerator, thereby reducing the overall volume of the vehicle-mounted refrigerator and increasing the activity space of users in the vehicle.
