ABSTRACT:
A heat exchange apparatus includes a core mounted within a casing and two fans arranged to draw air from the exterior of a building through the core in a first path and to draw air from the interior of the building through the core in a second path. The core is made up from a plurality of tubular cells each formed from a single folded sheet of aluminum and having a slot shaped cross-section. The short sides of the slot are arranged to face the inlet of cold exterior air so that it impinges upon the outer surface of the short side. The fan drawing the warm air is arranged to direct air onto the other surface of the short side so that the short side and the surrounding portions of the long sides act as an effective heat exchange surface free from the seam of the tubular core which is arranged adjacent opposite the short side. A differentially perforated baffle plate spreads the cold air over core such that more cold air is directed to the warm end of the core. The amount of warm air passing through the core is arranged to be greater than the amount of cold air so as to maintain the core above frosting temperatures. The excess of air can be arranged by by-passing air to and from the interior of the building through openings in the casing.
