Description

TECHNICAL FIELD

[0002] A reciprocating piston compressor for a refrigerator generally comprises a pump body and a housing component. The housing component generally comprises a housing, a suction pipe, a discharge pipe, a process pipe, a machine foot, a relay bracket, a wiring terminal and the like parts, which are all made of metal materials, wherein the suction pipe and the discharge pipe are made of copper pipes, which have a high thermal conductivity and can quickly conduct heat between the discharge pipe, the housing and the suction pipe. The pump body pushes refrigerant vapor to flow, the refrigerant vapor flows into the suction pipe of the housing component, is compressed by the pump body and then flows out from the discharge pipe of the housing component. The characteristics of the refrigerator refrigeration system determine that the refrigerant vapor flowing into the suction pipe of the compressor is in a low-temperature state, and the refrigerant vapor flowing out from the discharge pipe after being compressed by the pump body is in a high-temperature state. When the high-temperature refrigerant vapor flows through the discharge pipe, harmful heat is conducted to the housing, and the housing conducts the harmful heat to the suction pipe, so that the temperature of the suction pipe rapidly rises and heats the low-temperature refrigerant vapor flowing into the suction pipe, thus causing the suction overheat of the compressor and a significant reduction in the intake efficiency.
