PLATE-FIN-TYPE HEAT EXCHANGER

摘要

Plate-fin-type heat exchanger wherein one of a fluid of high temperature side and a fluid of low temperature side perfoms continuous operation, while the other repeats intermittent operation. In this plate-fin-type heat exchanger the ratio of hAs (coefficient of heat transfer x area of heat transfer) of both passages (A, B) is increased by using fins (1, 2, 3) having different coefficients of heat transfer and different areas of heat transfer, and thereby thermal fatigue produced particularly in a separating plate partitioning between the passage (A) of high temperature side and the passage (B) of low temperature side is alleviated and the life of the heat exchanger can be extended.
