COOL HEAT TRANSFER DEVICE OF STIRLING REFRIGERATOR

摘要

PROBLEM TO BE SOLVED: To provide a cold transfer device of a Stirling refrigerator capable of eliminating the possibility of damage to inflow ports and outflow ports for a working fluid at a condensing part while reducing heat resistance between the cooling end part and the condensing part of the Stirling refrigerator. SOLUTION: This cold transfer device 21 of the Stirling refrigerator 10 comprises the condensing part 31 having flow passages 311 and 316 for flowing the working fluid flowing therein from the inflow ports 313 and 314 to the outflow ports 315 and 316 and acquiring a cold generated at the cooling end part 11 of the Stirling refrigerator 10 by condensing the working fluid flowing in the flow passages 311 and 312, and transfers the cold acquired at the condensing part 31 to a specified cooling portion. The device also comprises a tightening means 41 fitting the condensing part 31 to the cooling end part 11 by tightening after it is restricted that tightening forces act on the inflow ports 313 and 314 and the outflow ports 315 and 316.
