Problems solved by technology

However, such a sound-absorbing effect is not very good, and the heat transfer coefficient of the cast iron material itself is relatively high. Under the constant impact of high-temperature and high-pressure gas, the heat will radiate into the compressor shell through the material itself, causing the compressor shell to As temperature rises, efficiency decreases

Embodiment Construction

[0013] refer to Figure 1 ~ Figure 2 1. Refrigerator compressor exhaust silencer structure, which includes a cylinder head 1 with a silencer chamber 12 and a valve plate 2 connected to the end face of the silencer chamber 12. The inner surface of the silencer chamber 12 is provided with a heat insulating layer.

[0014] As a further preferred embodiment, the muffler cavity 12 is provided with an inner liner 11 attached to its inner surface, and the inner liner 11 is a polymer material member with poor thermal conductivity, thereby forming the heat insulation layer. Of course, in the actual assembly, more suitable spacers or gaskets can be added according to the air tightness, such as figure 2 As shown, add gasket 3 and spacer 4 between valve piece 2 and inner bushing 11, install suction valve piece 5 and valve plate gasket 6 between valve piece 2 and the cylinder seat to be connected, etc. etc., these are all common structures of the suction and discharge parts of conventio...

Abstract

The invention discloses an exhausting and sound deadening structure of a refrigerator compressor. The exhausting and sound deadening structure comprises a cylinder cover and a valve plate, wherein the cylinder cover is provided with a sound deadening cavity; the valve plate is connected with the end face of the sound deadening cavity; and a heat insulating layer is arranged on the inner surface of the sound deadening cavity. In the invention, the heat insulating layer is arranged in the sound deadening cavity to ensure that high-temperature high-pressure gas exhausted from a gas vent of the compressor is depressurized and silenced by the sound deadening cavity, the heat of the gas per se is blocked by the heat insulating layer and cannot be dissipated in a shell of the compressor through the cylinder cover or the valve plate and most of heat can only be exhausted via an exhaust path; and therefore, the complete machine shell temperature of the compressor can be reduced and the efficiency of the compressor is increased. The exhausting and sound deadening structure disclosed by the invention is suitable for serving as an exhaust system structure of the refrigerator compressor.

Description

technical field [0001] The invention relates to an exhaust system structure of a refrigerator compressor. Background technique [0002] The refrigerator compressor includes a shell and a cylinder assembly located in the shell. The cylinder assembly includes a cylinder block and a cylinder head connected to the cylinder block. The internal mechanical structure of the cylinder block has an air suction system and an exhaust system. The strokes play the role of suction and exhaust respectively. The process of inhalation and exhaust will generate noise due to changes in air pressure. The silencer of the suction part of the mainstream compressor products on the market is realized by installing a suction muffler made of plastic material, and the exhaust system is used because the exhaust pressure is high and the plastic parts cannot meet the requirements of use. The muffler cavity on the cast iron cylinder head is used to achieve the purpose of muffler, that is, the high-temperat...
