A heat exchanger apparatus of the type having a rigid, unitary, parallel piped shaped core mounted in a frame defining support areas for the core. The core is formed of a plurality of thin parallel plates defining alternating passages for two different gas flows. Each plate is connected to an adjacent plate by parallel elongated bars along side edges thereof, the bars being of stronger construction than the plates. The core has four vertical corners, a pair of lower transverse corners and a pair of upper transverse corners. The frame includes a pair of spaced parallel plates and transverse structural connectors. Seal means are provided both between the vertical corners and the transverse corners of the core and the adjacent surfaces of the frame defined by the pair of plates and by the structural connectors. |
