Air-to-air heat exchanger

Abstract

A heat exchanger with metallic or otherwise conductive exchanger plates disposed in substantial parallelism within the exchanger. In making the exchanger, the exchanger plates are arranged in substantial parallelism and edges joined together with clips which tie the plates together as a unit bundle. A layer comprising a mixture of hardenable resin and reinforcing material is prepared, and the unit bundle of plates is placed with a set of adjacent edges of the plates in said layer. When the resin hardens, the layer forms a rigid slab extending along said set of edges. The process may be repeated on the opposite set of adjacent edges in the bundle of exchanger plates. The hardened resin masses which bind the edges of the plates together form part of an enclosing housing which is prepared about the exchanger plates to complete the exchanger.
