STIRLING REFRIGERATOR

摘要

Provided is a Stirling refrigerator having enhanced cooling capacity through improving exhaust-heat efficiency of the electromagnetic reciprocating drive mechanism. The Stirling refrigerator includes: a casing having a cylindrical portion and a body portion; a cylinder provided with a mount housed within the casing, the mount formed of a metal exhibiting high thermal conductivity; a piston and a displacer housed in the cylinder in a reciprocable manner; a stator of an electromagnetic reciprocating drive mechanism, the stator held on the mount and arranged within the body portion; and a mover of the electromagnetic reciprocating drive mechanism, the mover connected to the piston. The casing is partially formed with a heat-conduction block formed of a metal exhibiting favorable thermal conductivity thermally in contact with the mount. A heat generated at a compression chamber and an electromagnetic reciprocating drive mechanism can be efficiently released to the outside of the casing.
