HEAT EXCHANGE UNIT AND ADSORPTION TYPE REFRIGERATOR

PROBLEM TO BE SOLVED: To provide a heat exchange unit and an adsorption type refrigerator capable of being miniaturized and reduced in weight, and reducing costs.SOLUTION: A heat exchange unit 1 includes a housing portion 3 composed of a metallic thin plate 4 and provided with a spacial portion 5 inside, a heat medium 9 accommodated in a lower spacial portion 5a defined by vertically dividing the spacial portion into two, an adsorbent 11 accommodated in an upper-side upper spacial portion 5b, a first path 15 extending along the substantially whole face of a lower face of the housing portion so that any of cold raw water and cooling water selectively passes therethrough, and a second path 19 extending along the substantially whole face of an upper face of the housing portion so that any of warm water for heating the adsorbent and cooling water for cooling the adsorbent selectively passes therethrough. The lower spacial portion and the upper spacial portion extend in a longitudinal direction, and their heights hu and hd in a vertical direction are shorter than a length La in a longitudinal direction and a length Lb in a lateral direction of the corresponding lower spacial portion and upper spacial portion.SELECTED DRAWING: Figure 1 【課題】小型軽量化及びコスト低減が可能な熱交換ユニット及び吸着式冷凍機を提供する。【解決手段】熱交換ユニット１は、金属製の薄板４で形成され内部に空間部５が形成された筺体部３と、上下２分割された空間部のうち下側空間部５ａに収容された熱媒体９と、上側の上部空間部５ｂに収容された吸着剤１１と、筺体部の下面の略全面に沿って延在し、冷原水及び冷却水のいずれかを選択的に通水可能な第一通路１５と、筺体部の上面の略全面に沿って延在し、吸着剤を加温する温水及び吸着剤を冷却する冷却水のいずれかを選択的に通水可能な第二通路１９と、を備え、下側空間部及び上側空間部は、前後方向に延在し且つ夫々の上下方向の高さｈｕ，ｈｄは、対応する下側空間部及び上側空間部の前後方向長さＬａ及び左右方向長さＬｂよりも短い。【選択図】図１
