Auxiliary heat dissipation device applied to refrigerator compressor

Abstract

The invention discloses an auxiliary heat dissipation device applied to a refrigerator compressor. The auxiliary heat dissipation device comprises heat dissipation fins and heat tubes or a loop heat tube, wherein the plurality of heat tubes are annular and surrounded on the side surface of the compressor; the loop heat tube is spiral and surrounded on the side surface of the compressor; the inner ring surfaces of the heat tubes or the inner ring surface of the loop heat tube clings to an upper shell of the compressor; the heat dissipation fins are embedded on the heat tubes or the loop heat tube, uniformly and vertically arranged, and vertical to the side surface of the upper shell of the compressor; a combined heat dissipation structure of the heat tubes or the loop heat tube, and the heat dissipation fins is located at a lower end of a condenser; in the plurality of heat tubes, a distance between each two heat tubes at a lower end is greater than a distance between each two heat tubes at an upper end; or in the loop heat tube, a spiral lead distance of an upper ring is greater than a spiral lead distance of a lower ring. According to the invention, the auxiliary heat dissipation device for the compressor, which is not provided with an additional power device, noiseless, and efficient in performance, is designed on the compressor; and the auxiliary heat dissipation device for the compressor is simple in structure, easy to install and maintain, remarkable in heat dissipation effect, beneficial to prolong the service life of the compressor, and energy-saving.

Description

technical field [0001] The invention relates to the field of refrigerator heat dissipation, in particular to an auxiliary heat dissipation device used in a refrigerator compressor, which adopts a combination of heat pipes and heat dissipation fins. Background technique [0002] The application of refrigerators is becoming more and more extensive now, and it is difficult for people to live without it. Refrigerators are mainly composed of compressors, dry filters, capillary tubes, and evaporating dishes. Absorb the heat of the cold room through the refrigeration cycle, and discharge the heat to the outside of the cold room. Therefore, refrigerators have important requirements for heat dissipation and heat insulation. Excellent heat dissipation and heat insulation performance can significantly reduce the power consumption of the refrigerator, improve the cooling efficiency and prolong the service life of the refrigerator. Reasonable design and optimization of each component ...

Problems solved by technology

This is not only detrimental to the normal function and use of the equipment, but also has an adverse effect on daily maintenance such as compressor lubrication. Commonly, the failure of the refrigeration cycle caused by high-temperature carbon deposits in the cylinder head of the compressor causes refrigeration failures in the refrigerator and shortens the use of the compressor. life

At the same time, the overall temperature of the compressor is too high and the temperature is uneven, so that the heat of the condensing agent cannot be discharged in time, increasing the compression resistance of the compressor, increasing power consumption, and adversely affecting the service life of the compressor

However, the heat dissipation performance of the traditional compressor itself is easily overlooked.
