A plurality of horizontally positioned plates stacked on top of one another, with thin film plastic sheets separating each adjacent pair of plates. Each plate is formed with a substantially identical, horizontally extending, vertically through passageway, with the sheets separating the passageways of each plate. Upper and lower pressure plates, provided with pressurized air bags, maintain uniform pressure across the plates to prevent leakage from the passageways. Manifold devices at opposite ends of the passageways direct a first heat exchange medium through a first set of vertically alternate passageways, and direct a second heat exchange medium through a second set of vertically alternate passageways positioned intermittently with respect to the first set of passageways.

A heat exchange apparatus adapted to place a first fluid heat exchange medium into heat exchange relationship with a second heat exchange medium, said apparatus comprising: a. a plurality of spacing plates, each of which has a perimeter portion and an interior portion providing at least one pair of elongate sidewalls defining a vertically through, horizontally extending elongate passageway which is open from a top surface to a bottom surface of its related plate, each of said passageways being arranged in a substantially identical pattern, said plates being stacked above one another in longitudinal and transverse alignment, with the perimeter portions being stacked in vertical alignment to form a perimeter of a heat exchange area, and with the interior portions being stacked in vertical alignment to position said passageways one directly above the other, each passageway having a first end and a second end, b. a plurality of thin film sheets, positioned intermittently between said spacing plates, with one sheet between each adjacent pair of spacing plates, so that each passageway is separated by a related pair of said sheets from the passageways immediately above and below, with each passageway being defined on side portions thereof by the sidewalls of the interior portion of its related plate, and on upper and lower portions by its related pair of sheets, c. a distributing means for said fluid medium, said distributing means comprising: 1. a first manifold means connecting to the first ends of a first set of alternately spaced passageways, 2. a second manifold means connecting to the first ends of a second set of alternately spaced passageways positioned alternately between the passageways of the first set, 3. a third manifold means connecting to the second ends of the first set of alternately spaced passageways, 4. a fourth manifold means connecting to the second ends of the second set of alternately spaced passageways, whereby said first heat exchange medium can be directed through said first set of alternately spaced passageway by means of said first and third manifold means, and said second heat exchange medium can be directed through such second set of alternately spaced passageways by means of said second and fourth manifold means, with heat exchange taking place across sheet portions separating vertically adjacent passageways, in a manner that one of said heat exchange mediums in one of said passageways is in heat exchange relationship with the other of said heat exchange mediums in the adjacent passageways immediately above and below.
