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.
