Claims

[Scope of utility model registration request]

A compressor main body driven by an electric motor is housed in a housing, the compressor main body has a cylinder block having a cylinder chamber, a piston rotationally driven within the cylinder chamber, and an end face of the cylinder chamber supports a crankshaft. In a rotary compressor closed by an upper bearing and a lower bearing, a perforated partition wall partitions a door-shaped space formed by the upper bearing, the lower bearing, the housing, and the cylinder from the discharge gas chamber above the upper bearing; The heat exchanger is attached to the outside of the housing and has one end passing through the housing and opening into the discharge gas chamber, and the other end passing through the housing and opening into the fan-shaped space. rotary compressor.
