Description

Technical Field

[0001] The utility model belongs to the technical field of electrical appliance accessories, and in particular relates to a refrigerator condenser. Background Art

[0002] The condenser is a crucial heat exchange system of the refrigerator. Its biggest function is heat dissipation and heat exchange. When the refrigerator is still in operation, the hot gas generated by the operation of the refrigerator compressor will spread into the air through the long internal tubes, and the compressor will convert these low-temperature and low-pressure gases into high-temperature and high-pressure gases. Then the condenser will convert these gases into liquid, that is, high-temperature and high-pressure liquid. After fluorine liquefaction to generate heat, the liquid will be converted into low-temperature and low-pressure liquid through the capillaries. In this way, the refrigerator realizes an exchange of heat.

[0003] The existing refrigerator condensers on the market have the advantages of simple structure and good refrigeration effect. However, the condensers used in the prior art for refrigerators have a small coverage area when dissipating heat, which affects normal operation.

[0004] The prior art disclosure application number is CN202021745826.8, which is a rapid heat dissipation device for a condenser tube for a refrigerator. The rapid heat dissipation device for a condenser tube for a refrigerator enters the heat dissipation shell through the sixth pipe along the water-cooling pipe, and the wind blown by the heat dissipation fan is started to cool the water in the ninth pipe. The hot air is discharged from the heat dissipation holes, thereby realizing rapid heat dissipation of the condenser tube. However, the case still has problems when used: the coverage area and effect of heat dissipation are poor, which will make the heat conduction range smaller, thereby affecting the overall heat dissipation efficiency.

[0005] In view of this, the existing structure and defects are studied and improved, and a refrigerator condenser tube rapid heat dissipation structure is proposed in order to achieve a more practical purpose. Utility Model Content
