Abstract

The invention discloses a piston heat control device for a refrigerator compressor. A piston is connected onto a crank through a connecting rod, the connecting rod is rotatably connected with the interior of a connecting rod inserting hole of the piston, the piston heat control device for the refrigerator compressor comprises a heat insulation part and a piston cooling mechanism, the heat insulation part is arranged on the end face of the piston, and the piston cooling mechanism can cool the piston. Due to the addition of the heat insulation part, the heat insulation performance of the pistonis increased, and the piston can be prevented from conducting additional heat energy onto chamber air. In addition, the piston cooling mechanism can cool the piston, and heat energy which is not beneficial to the piston is guided to the outside in time through heat exchange, so that the output power loss of the whole compressor is reduced by the measures, the energy is saved, and the efficiency isimproved.

Description

technical field [0001] The invention relates to a refrigerator compressor, in particular to a piston heat control device for a refrigerator compressor. Background technique [0002] At present, the market is paying more and more attention to energy efficiency indicators, so the performance requirements for refrigerator compressors are getting higher and higher. The piston generates heat due to friction in the compressed air and is affected by the motor, and the temperature will gradually rise. The heat exchange between the inner end surface of the piston and the piston hole and even the air in the entire refrigerator compressor chamber is significant, which will cause the air temperature in the refrigerator compressor chamber. As a result, it increases, resulting in energy efficiency loss and reducing the energy efficiency of the compressor. Therefore, how to provide a piston structure with good heat transfer control effect so as to improve the energy efficiency ratio of th...
