COOLER FOR PULSATING TUBE REFRIGERATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a cooler for a pulsating tube refrigerating machine capable of improving a general performance of the refrigerating machine by constituting a refrigerant compression type refrigerating cycle with a precooler for previously cooling high temperature and high pressure working gas as an evaporator, and smoothly radiating a generated heat of the working gas and a driver.;SOLUTION: The cooler for the pulsating tube refrigerating machine comprises the driver 10 for pumping the working gas to reciprocate to move, a refrigerating unit 200 having a pulsating tube including a cryogenic part formed by an operation of the gas, and a refrigerant compression type cooling means engaged between the driver 100 and the unit 200 and having the precooler 400 in which the gas flows as an evaporator and a compressor 460, a condenser 470 and an expansion valve 480 are sequentially coupled to a refrigerant tube 450 coupled to the precooler 400 to form one refrigerating cycle.;COPYRIGHT: (C)2002,JPO
