Abstract:
1. A stacked plate-type heat exchanger including: a plurality of dish-shaped heat exchanger plates arranged one next to the other to form a nested heat exchanger plate stack, each of the heat exchanger plates having a planar central portion with a peripheral flange projecting therefrom; a plurality of first and second fluid flow channels formed between the heat exchanger plates for first and second fluids respectively; first fluid and second fluid chambers formed in the stack in communication with the first and second fluid channels respectively; an end plate with an end plate central planar portion and a peripheral flange projecting from the end plate central planar portion, the peripheral flange of the end plate projecting in an opposite direction and sealably nested within the peripheral flange of a final heat exchanger plate in the plate stack; and a planar reinforcing plate secured to an inner surface of the end plate central planar portion between the end plate central planar portion and the final heat exchanger plate, a further fluid channel for one of the first and second fluids being located between the planar reinforcing plate and the final heat exchanger plate.
