Abstract
A heat exchange apparatus made up of a plurality of sheets, desirably made of thin film plastic, bonded one to another to form a unitized heat exchange structure. Alternate first pairs of sheets are bonded one to another along a first set of longitudinally extending bond lines positioned at first transverse locations along width dimensions of the sheets. There is a second set of pairs of alternately spaced sheets (made up of adjacent sheets of adjoining first pairs of sheets) which are bonded one to another along a second set of longitudinally extending bond lines positioned transversely intermittent of the first set of longitudinal bond lines. These sheets are expanded from one another to form a plurality of diamond-shaped heat exchange passageways arranged in parallel rows. In the preferred form, each end of the heat exchange structure is bonded into a molded base member, which in turn is connected to a related manifold structure. Each manifold structure has a pair of oppositely positioned manifold chambers leading to parallel alternately spaced feed passages, with each alternate set connecting to a related alternate set of heat exchange passageways.
