Heat exchanger and method of manufacturing a heat exchanging member of a heat exchanger
First Claim
1. A heat exchanger in which an alternate flow of supply air and exhaust air are supplied in opposite directions between a plurality of stacked heat exchanging members, each of said heat exchanging members comprising a paper member having a moisture permeability, said paper members comprising a corrugated portion which is corrugated in the width direction and header defining portions for defining header portions including flattened, continuous predetermined length portions of the corrugated portion at each of the longitudinally opposite ends of the corrugated portion formed under pressure.

Abstract
A heat exchanger, in which an alternating flow of supply air and exhaust 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 defining 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.

14. A heat exchanger in which an alternate flow of supply air and exhaust air are supplied in opposite directions between a plurality of stacked heat exchanging members, each of said heat exchanging members comprising a first paper member having moisture permeability and corrugated in the width direction and comprising flattened, continuous portions extending outwardly in the longitudinal direction from said corrugated portion at the longitudinally opposite ends of said corrugated portion formed under pressure, and a pair of second paper members having one end joined to said flat portions and the other end extending flatly in the longitudinal direction to define header defining portions for defining header portions.
