ADSORPTION HEAT EXCHANGER

摘要

An adsorption heat exchanger (20) is constituted by a fin and tube heat exchanger. The adsorption heat exchanger (20) is formed with a first tube row (41), a second tube row (42), and a third tube row (43), arranged in the order mentioned from upstream to downstream of the air current. In each fin (30), a portion closely contacted with a heat transmission tube (40) in each of the tube rows (41-43) constitutes a main body portion. Furthermore, in each fin (30), a portion extending from the main body portion to upstream of the air current constitutes a front edge portion and another portion extending from the main body portion to downstream of the air current constitutes a rear edge portion. Furthermore, in each of the fins (30) of the adsorption heat exchanger (20), the length of the front edge portion is longer than that of the rear edge portion.
