Abstract
Method of manufacturing a heat exchanger body composed of a plurality of facially-opposed corrugated rectangular sheets of a deformable material with corrugations in alternate sheets crossing the corrugations in the intervening sheets and forming a series of channels through which two streams of gaseous medium are forced crosswise in heat exchange relationship with one another. The juxtaposed edges of the sheets are displaced so that the edges on the same side of the body are alternately sealed and form openings therebetween for admission of the gaseous media into the channels. The edges of the corrugated sheets, prior to being assembled into a heat exchange body, are pressed flat, with flat edges at two of the opposite sides extending substantially in the same plane and the contiguous flat edges at the other two opposite sides being displaced relative to the plane of the first two opposite edges.
