HEAT EXCHANGER

摘要

A heat exchanger is provided to improve the humidity exchange efficiency and reduce the gas exhaustion rate by using a partition member made of hydrophilic fiber and containing hygroscopic agent. A heat exchanger includes a partition member(2) in which the interval is maintained by a spacing member(3). The partition member is an air shield sheet made of hydrophilic fiber, and coated with hygroscopic agent in order to improve the moisture permeability. The spacing member is made of cellulose fiber as main component and contains flame retardant such as flame retardant paper of 60~120mum including sulfamic acid guanidine.
