Abstract

본 발명은 밀폐형 압축기의 냉각장치에 관한 것으로서, 특히 전동기의 작동에 따라 회전되는 크랭크샤프트와, 싱기 크랭크샤프트의 회전력에 의해 직선 왕복 작동하여 실린더 보어 내로 유입된 냉매를 압축시키는 피스톤과, 상기 크랭크샤프트의 하측에서 편심 회전하여 오일을 펌핌하는 오일 픽업 및 상기 오일 픽업에 의해 펌핑된 오일을 크랭크샤프트의 상측으로 공급하여 토출시키는 하부 및 상부 오일 통로를 포함하는 것을 그 특징으로 한다. 따라서, 압축기의 작동 중에 오일이 계속적으로 크랭크샤프트의 전체 주변부로 공급됨으로써 마찰에 의해 발생되는 열을 냉각시켜 압축기의 과열을 방지함과 동시에 냉매 가스의 압축비를 저하시켜 압축 효율을 증대시키고, 더욱 온도 상승에 의한 유막의 파괴에 의해 발생하는 마찰부에 훤활한 윤활 작용이 이루어지도록 하여 신뢰성을 향상시킬 수 있는 등의 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for a hermetic compressor, and in particular, a crankshaft rotated according to the operation of an electric motor, a piston for linearly reciprocating operation by the rotational force of the crankshaft to compress refrigerant introduced into a cylinder bore, and the crankshaft. It characterized in that it comprises an oil pickup for eccentric rotation in the lower side of the pump and the lower and upper oil passage for supplying and discharging the oil pumped by the oil pickup to the upper side of the crankshaft. Therefore, oil is continuously supplied to the entire periphery of the crankshaft during operation of the compressor, thereby cooling the heat generated by friction to prevent overheating of the compressor and at the same time lowering the compression ratio of the refrigerant gas to increase the compression efficiency and further increase the temperature. There is an effect such that the lubricating action is performed smoothly to the friction portion generated by the breakdown of the oil film due to the rise, thereby improving the reliability.
