Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2007/119843
Kind Code:
A1
Abstract:
A heat exchanger that even in an environment where dew condensation is repeated, can maintain its basic performance. For obtaining it, a unit element is formed by integral molding with a resin of a heat transfer plate, spacing rib for ensuring of heat transfer plate spacing and shielding rib for shielding of gas current leakage. Multiple unit elements formed are superimposed one upon another so as to provide a ventilation channel between heat transfer plates. Accordingly, heat exchange via the heat transfer plates is carried out by flowing of a primary gas current and secondary gas current through ventilation channels. The heat transfer plates are constructed of a water-insoluble flame proofing moisture permeable resin film, and the resin consists of a water-insoluble flame proofing resin.
