Abstract

The invention discloses a device suitable for natural convection heat dissipation of the surface of a shell of a refrigerator compressor. According to the device, grooves matched with fins are formed in the circumference of an upper shell of the compressor, and grooves matched with heat pipes are formed in the upper shell of the compressor in the vertical direction. The heat pipes are divided into two types, the heat pipes in one type are cylindrical, the multiple cylindrical heat pipes are arranged, and the cylindrical heat pipes and cylindrical portions of the arch-shaped heat pipes are evenly and vertically arranged on the circumference of the upper shell of the compressor. The cooling fins are divided into two types and are the large inner ring cooling fins and the small inner ring cooling fins. The diameter of an inner hollow ring of each large inner ring cooling fin ranges from 163 mm to 164 mm, and the diameter of an inner hollow ring of each small inner ring cooling fin ranges from 30 mm to 32 mm. By the adoption of the device, the heat pipes are arranged on the upper surface of the shell of the compressor, heat is rapidly transmitted in the heat pipes and conducted to the cooling fins for natural convection heat dissipation, the shape and the intervals of the fins and ventilation openings are reasonably designed, natural convection heat dissipation is enhanced, and the device is simple and efficient.

Description

technical field [0001] The invention relates to the field of refrigerator heat dissipation, in particular to a device suitable for natural convection heat dissipation on the surface of a refrigerator compressor shell. Background technique [0002] Refrigerators are very common household appliances and play an important role in improving our quality of life. There are various types and shapes of refrigerators, as well as various functions and types. However, the main components and working principles of refrigerators are generally the same. The structure of household refrigerator products is not complicated, and generally consists of important components such as compressors, condensers, dry filters, capillary tubes, and evaporators connected into a circuit. Refrigerators generate a lot of heat during the working process, and the heat is enclosed in a closed space, which is difficult to dissipate, which has an important impact on the working performance of the refrigerator. ...
