HEAT EXCHANGER, STIRLING ENGINE, AND STIRLING COOLING STORAGE

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger of high heat exchanging efficiency and a Stirling engine of high capacity. SOLUTION: An internal heat exchanger 18 provided inside a high temperature part 2 of a Stirling refrigerator is composed of an annular corrugated fin 180 formed in corrugated shape along a circumferential direction (a direction of an arrow mark DR2). The corrugated fin 180 has a rugged part for increasing the surface area of a wave surface, on the wave surface of the wave-like part. An internal heat exchanger provided inside a low temperature part of the Stirling refrigerator also has the same constitution. COPYRIGHT: (C)2007,JPO&INPIT
