Title: Stirling refrigerator
Inventor: KITAMURA YOSHIYUKI
IPC: F25B9/14
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To obtain a Stirling refrigerator capable of preventing a collision of a displacer with piston and having a space conservation for enhancing cooling performance by always regulating their phase difference near its optimum value. SOLUTION: A piston 3 is vibrated in a driving frequency of the Stirling refrigerator to bring about a periodic pressure change at sealed working gas of an operating space having a compressing space 6, an expanding space 7 and a channel for communicating the space 6 with the space 7, and a displacer 2 is reciprocated in the same period as that of the piston and in a different phase. Then, temperature sensors 13 are respectively mounted at a high- temperature side heat exchanger 9 and a low-temperature side heat exchanger 10, A temperature difference is obtained from the detected temperatures of the exchangers. A command is sent from a control circuit 15 to a movable member 14 based on the difference to slide the member so that a pressure in the compressing space becomes constant.  Even when the frequency is changed so that a vibrating period of the piston is altered, a resonance frequency of the displacer can be matched to the driving frequency by applying a current in the driving frequency to a coil 16.
