ABSTRACT:
The specification discloses an air-to-air, polymeric heat exchanger having a housing and a core removably mounted within the housing. The housing includes four generally indentical duct units, which are secured to one another, and a top and a bottom, which are secured to the duct units. The core includes a pair of end walls and a plurality of tubes extending between, and opening through, the end walls. Each end wall includes a plurality of tubular projections or pockets extending from the end wall in a common direction. Opposite ends of the tubes are secured within the tubular pockets in the opposite end walls. A method of constructing the core includes the step of severing the tubular projections after the tubes are positioned therein to expose the tube interiors through the end walls. Preferably, the tubular projections are severed using a hot wire to also fuse the tubes within the end walls.
