HEAT EXCHANGER AND METHOD OF MANUFACTURING A HEAT EXCHANGING MEMBER OF A HEAT EXCHANGER

摘要

A heat exchanger, in which an alternating flow of supply air and exhaus t air are supplied in opposite directions between a plurality of stacked heat exchanging members, is characterized in that the heat exchanging members each is composed of a first paper member having a moisture permeability and corrugated in the width direction and having flat portions at the longitudinally opposite ends flattened under pressure, and a pair of second paper members having one end joined to the flat portions and the other end side extending flatly in the longitudinal direction to define a header defining portion for defini ng a header portion, so that the number of the parts can be decreased and the assembly can be made easier, whereby a heat exchanger with an improved productivity can be provided. A method for manufacturing a heat exchanger is also disclosed.
