PROBLEM TO BE SOLVED: To provide a heat exchanger capable of realizing a low cost while improving a charging efficiency as well as small-sized formation and cold heat output per volume of an adsorptive type heat exchanger.SOLUTION: Adsorption agent is filled in a fin clearance of an adsorption heat exchanger and a mass of adsorption desorption refrigerant per heat exchanger volume is increased. Then, a refrigerant vapor passage is arranged at the layer, an increasing of an amount of refrigerant vapor adsorbed or desorbed per unit time per unit mass of adsorption agent is attained to get a high output. Further, in order to restrict a reduction of charging rate, the structure is made to have the refrigerant vapor passage at a part of the layer. Further, as a fin type of the heat exchanger, a corrugate fin is employed to promote heat transfer to the adsorption agent and a louver fin is employed to restrict peeling-off state between the adsorption agent layer and the fin. Inside part of the pipe in the heat exchanger is made as a fine pipe structure capable of improving heat transfer. This invention has employed a method for manufacturing a low cost adsorption heat exchanger in which slurry having adsorption agent, water, and binder material mixed to each other is flowed between the fins of a commercial radiator heat exchanger to cause the layer to be easily dried and its mass production to be available.SELECTED DRAWING: Figure 2 【課題】吸着熱交換器の充填率の向上と小型化及び体積あたりの冷温熱出力を向上させながら低コスト化を実現することができる熱交換器を提供する。【解決手段】吸着熱交換器のフィンすき間に吸着剤を充填し、熱交換器体積あたりの吸脱着冷媒質量を増加させた。そして、層に冷媒蒸気通路を設け、吸着剤単位質量あたり単位時間あたりに吸脱着する冷媒蒸気量の増加を図り高出力にした。なお、充填率低下を抑制するために、層の一部に冷媒蒸気通路を有する構造にした。また、熱交換器のフィン形式にコルゲートフィンを採用して吸着剤への伝熱促進を図り、ルーバーフィンを採用して吸着剤層とフィン間のはく離を抑制した。熱交換器の管内は熱伝達の向上が可能な微細管構造とした。吸着剤と水と結合材を混合したスラリーを市販ラジエータ熱交換器のフィン間に流入し、層を容易に乾燥させ、大量生産を可能にした低コスト吸着熱交換器の製作法を採用した。【選択図】図２
