DEFUMIDIFICATION ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a dehumidification element having enhanced heat exchange efficiency and excellent dehumidification efficiency. SOLUTION: A plurality of small diameter protruding parts 8 with an interconnection port 7 are provided at a circular arc swelled area 6 which is formed between a large diameter protruding part 3 with an air inlet 2 and a large diameter protruding part 5 with an air outlet 4. A dehumidification element body 14 is formed by jointing a dehumidification element board 12 formed from a resinous sheet 1 so that a swelled area 6 becomes outside and arranging a number of the dehumidification element boards in parallel. The thickness of the element becomes thin to enhance the heat exchange efficiency by providing a highly humid air inlet 16, a dehumidified air outlet 17 and a drain port 18. Thus, the dehumidification element having excellent dehumidification efficiency is obtained.
