The present invention relates to a core assembly for use in an air-to-air heat exchanger. The core is comprised of a plurality of square plates. Each plate is comprised of a square planar central region; a first pair of opposed edge flanges bent in a first direction with respect to the central region to form approximately 90 degree angle with the central region; and a second pair of opposed edge flanges bent in a direction opposite the first direction with respect to the central region to form approximately 90 degree angle with the central region. The core is formed by the plurality of square plates that are positioned into a stack of parallel plates such that the opposed flanges of one of the plurality of plates is located in contact with and inside mating opposed flanges of a plate directly adjacent thereto, thereby forming a plurality of air passages between adjacent plates such that two perpendicular air pathways are formed in an interleaved orientation. A frame is provided in contact with a bottom plate in the stack and a top plate in the stack for holding the plurality of plates in position.
Partie centrale d'un échangeur de chaleur air-air, comprenant une série de plaques carrées. Chaque plaque est constituée : d'une zone centrale carrée et plane; d'une première paire de rebords opposés, pliés dans une première direction afin de former un angle d'environ 90 degrés par rapport à la zone centrale; d'une seconde paire de rebords opposés, pliés, dans une direction opposée à la première direction, afin de former un angle d'environ 90 degrés par rapport à la zone centrale. La partie centrale est constituée d'une série de plaques carrées empilées parallèlement, de sorte que les rebords opposés d'une plaque s'insèrent et s'emboîtent à l'intérieur des rebords d'une plaque directement adjacente afin de créer, entre des plaques adjacentes, une certaine quantité de passages d'air perpendiculaires, qui forment deux trajectoires d'écoulement d'air entrelacées. Un cadre ancre les plaques inférieure et supérieure de la pile pour maintenir toutes les plaques en position.
