COLD ENERGY STORAGE UNIT AND PULSE TUBE REFRIGERATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a cold energy storage unit and a pulse tube refrigerating machine capable of reducing the cold energy storage unit inefficient loss by a simple constitution hardly accompanied with a cost increase. SOLUTION: In this cold storage unit 10 wherein a layered wire netting 12 formed by stacking a plurality of wire sheets 13 is mounted inside a metallic cylinder 11 opened at its both end parts as a cold energy storage material to exchange the heat with a working gas passing through the layered wire netting 12, the wire sheets 13 are a plain-woven or twilled woven metallic wire sheet applying a stranded wire 14 obtained by twisting two or three pieces of wires as a base material. This cold storage unit 10 is loaded in the pulse tube refrigerating machine. COPYRIGHT: (C)2005,JPO&NCIPI
