Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a device for cooling refrigerator compressors. Background Art

[0002] The components of a refrigerator mainly include a compressor, a condenser, an expansion valve and an evaporator. According to the control or use needs, auxiliary devices such as a pressure controller, a temperature controller, and a drying filter can be installed in the middle. When working, the gaseous refrigerant is compressed into a high-temperature and high-pressure gas by the compressor and then enters the condenser. The condenser is equivalent to a heat exchange device, which exchanges the high-temperature and high-pressure gaseous refrigerant into a low-temperature and high-pressure liquid refrigerant. The liquid refrigerant then passes through the expansion valve, which is a throttling device. Because the refrigerant flowing out of the expansion valve is restrained, the pressure of the refrigerant is reduced after it comes out, and the temperature continues to drop, becoming a gas-liquid two-phase, and then entering the evaporator. At this time, the refrigerant is heat-exchanged and vaporized in the evaporator, becoming a high-temperature and low-pressure gaseous refrigerant and returning to the compressor to continue circulating. In the above process, the operating temperature of the compressor continues to rise, and timely heat dissipation is required to ensure the normal operation of the refrigeration system;

[0003] Chinese patent publication number CN217585013U discloses a compressor heat dissipation device for a freezer, wherein a water pump draws water from a water tank through a water pumping pipe, and the water pump then supplies water to a thermostatic tube through a water supply pipe, so that the thermostatic tube cools down the refrigeration compressor, and then the water in the thermostatic tube flows back into the water tank through a water outlet pipe, forming a water cycle, so that the refrigeration compressor can be better cooled, and air can be blown to the inside of an outer box by an air inlet assembly, so that the air can cool down the refrigeration compressor, so that the air outlet assembly can absorb heat and discharge the heat out of the outer box, so that the refrigeration compressor can be further cooled, which is more convenient and practical;

[0004] The above technology combines air cooling with water cooling to improve the heat dissipation effect of the compressor. However, the cooling structure of air cooling and water cooling is combined with the compressor as a whole, which is large in size and heavy in weight, and is not conducive to layout in the limited space of the refrigerator. In addition, the wind resistance of the air inlet component to the internal air blowing and cooling of the outer box is large, and the heat exchange area is limited, which limits the air cooling effect to a certain extent. Therefore, the utility model provides a refrigerator compressor heat dissipation device for solving the above problems. Utility Model Content

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] See also Figure 1-6 The utility model provides a refrigerator compressor heat dissipation device, comprising a heat dissipation box 1, a compressor case 2 and a heat exchange tube 3 connected therebetween, wherein a compressor body 4 is arranged in the compressor case 2, and the heat exchange tube 3 is spirally wound around the outside of the compressor body 4;

[0029] Specifically, the contact length between the compressor body 4 and the heat exchange tube 3 can be extended, thereby effectively improving the heat exchange effect between the compressor body 4 and the heat exchange tube 3 , and facilitating the cooling of the compressor body 4 .

[0030] Furthermore, a heat-insulating layer 21 is bonded and fixed to the inner wall of the compressor case 2, and the heat-insulating layer 21 is made of polyurethane rubber material;

[0031] Specifically, polyurethane rubber has the advantages of high strength, high elasticity, high wear resistance, tear resistance, aging resistance, and good thermal insulation. It plays a role in blocking the heat exchange between the inside and outside of the compressor chassis 2, and reduces the impact of the environment on the temperature of the compressor body 4. On the other hand, polyurethane rubber can also alleviate the vibration of the compressor body 4 during operation, reduce the noise of the compressor body 4 during operation, and play a role in shock absorption and heat insulation.

[0032] Further, a heat exchange tube 3 is sleeved on the outer side of the compressor body 4, one end of the heat exchange tube 3 extends into the top of the heat dissipation box 1 and is connected to a filter assembly 5, the other end of the heat exchange tube 3 extends into the bottom of the heat dissipation box 1 and is connected to an input end of a water pump 6, the filter assembly 5 includes a water tank 51 fixedly embedded in the top wall of the heat dissipation box 1, the water tank 51 is connected to one end of the heat exchange tube 3, a threaded opening 52 is provided on the upper side of the water tank 51, a tank cover 53 is threadedly connected to the threaded opening 52, a filter cartridge 54 is fixedly connected to the lower middle side of the tank cover 53, a socket 55 is provided at the bottom end of the filter cartridge 54, and the outer wall of the bottom end of the filter cartridge 54 is densely covered with filter holes 56;

[0033] Specifically, after the cold water enters the filter cartridge 54, larger impurities will be filtered by the filter holes 56, thereby removing impurities. Impurities in the water are effectively cleaned to prevent them from adhering to the inner wall of the heat exchange tube 3 or the heat dissipation tube 7 and affecting heat exchange.

[0034] Furthermore, the filter assembly 5 further comprises a column tube 57 fixedly embedded in the bottom wall of the water tank 51, the column tube 57 is connected with one end of the heat dissipation pipe 7, an annular groove 58 is formed on the outer side of the column tube 57, a sealing ring 59 is embedded in the annular groove 58, and the sealing ring 59 is in conflict with the inner wall of the socket 55;

[0035] Specifically, the filter cartridge 54 can be disassembled by loosening the bin cover 53, and the blocked particles can be removed through the socket 55 to prevent blockage. After adding water, the filter cartridge 54 is reinserted into the threaded opening 52, and the bin cover 53 is tightened. The sealing ring 59 contacts the inner wall of the socket 55 to seal the gap.

[0036] Furthermore, the two brushless fans 8 are located on the same axis, and dustproof nets 81 are fixedly embedded on ports of the two brushless fans 8 that are away from each other.

[0037] Specifically, the two brushless fans 8 direct air in the same direction, which effectively enhances the wind force, and the dustproof net 81 can filter dust in the air to prevent dust accumulation from affecting heat exchange.

[0038] Furthermore, a heat dissipation pipe 7 is connected between the filter assembly 5 and the output end of the water pump 6, and a brushless fan 8 for guiding the airflow to flow through the gap between adjacent heat exchange fins 72 is fixedly embedded on both the front and rear sides of the heat dissipation box 1, and the heat dissipation pipe 7 is arranged in a serpentine structure, and a plurality of pipe sleeves 71 are sleeved on the outer side of the heat dissipation pipe 7, and heat exchange fins 72 are fixedly connected to both sides of the pipe sleeve 71, and adjacent heat exchange fins 72 are arranged parallel to each other;

[0039] Specifically, the hot water enters the filter cartridge 54 through the tortuous heat dissipation pipe 7, and the heat of the hot water is dissipated to the heat exchange fins 72 through the heat dissipation pipe 7 and the pipe sleeve 71, so that the temperature of the heat exchange fins 72 increases. At the same time, the brushless fan 8 is started to form an airflow that penetrates the heat dissipation box 1, and the airflow takes away the heat on the heat exchange fins 72, so that the hot water is cooled to cold water;

[0040] Specifically, the heat dissipation tube 7 is a copper tube, the heat exchange fins 72 and the tube sleeve 71 are both made of stainless steel, and the tube sleeve 71 and the heat dissipation tube 7 are bonded by a heat conductive potting adhesive to enhance the heat conduction effect.

[0041] Optionally, the gap between the upper and lower heat exchange fins 72 is between 1 cm and 2 cm, which can balance the wind resistance and air cooling effect. The heat exchange fins 72 can also be a wavy structure, which can increase the heat exchange area of ​​the heat exchange fins 72.

[0042] Working principle: when in use, the water pump 6 extracts the hot water in the heat exchange tube 3, and the hot water enters the filter cartridge 54 through the tortuous heat dissipation tube 7. The heat of the hot water is dissipated to the heat exchange fins 72 through the heat dissipation tube 7 and the tube sleeve 71, so that the temperature of the heat exchange fins 72 increases. At the same time, the brushless fan 8 is started to form an airflow that runs through the heat dissipation box 1. The airflow takes away the heat on the heat exchange fins 72, so that the hot water is cooled to cold water. After the cold water enters the filter cartridge 54, impurities with larger particles will be filtered by the filter holes 56, which plays a role in removing impurities. The filtered cold water re-enters the heat exchange tube 3 to exchange heat with the compressor body 4, and can take away the operating heat of the compressor body 4. It is worth mentioning that the setting of the thermal insulation layer 21 plays a role in blocking the heat exchange between the inside and outside of the compressor chassis 2, thereby reducing the influence of the environment on the temperature of the compressor body 4.
