Abstract
A heat exchanger for exchanging heat between a cooler first air flow and a warmer second air flow is disclosed. The heat exchanger comprises a heat exchanger unit having a housing containing a plurality of heat exchanger plates stacked together to form a stack. Each heat exchanger plate has four corners and an aperture located adjacent each corner, the heat exchanger plates being dimensioned and configured such that the apertures of the heat exchanger plates overlap to form a first, second, third and fourth air passageways in the stack. The heat exchanger plates are further configured to form an alternating series of first and second flat parallel air chambers in the stack, the first set of air chambers being continuous with the first and second air passages such that air can pass between the first and second air passages through the first set of air chambers, the second set of air chambers being continuous with the third and fourth air passageways such that air can pass between the third and fourth air passageways through the second set of air chambers. The stack of heat exchanger plates are further configured such that the first and second set or air chambers are substantially air tight such that air does not leak between the first and second set of air chambers. The heat exchanger unit has a first and second side, the first, second, third and fourth air passageways each having a first end open to the first side of the heat exchanger unit at a first port and an opposite second end opened to the second side of the heat exchanger unit at a second port. The stack is further adapted such that each port may be selectively plugged by a plug member, the heat exchanger unit having four plug members, each plug member plugging one end of each air passageway. Finally, the first, second, third and fourth air conduits, are each operatively coupled to one of the air passageways, the air conduits carrying the first and second air flows.
