HEAT EXCHANGER AND STIRLING ENGINE

摘要

A heat exchanger, comprising a metal cylindrical member (4) as an outer shell body, a metal corrugated fin (2) as a heat exchanging member fitted to the cylindrical member (4), and a coating layer (5) formed on at least one of the surface of the cylindrical member (4) and the surface of the corrugated fin (2). The corrugated fin (2) is press-fitted to the cylindrical member (4). The heat exchanger can be installed, for example, on the heat absorbing part and the heat radiating part of a Stirling engine.
