Abstract

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. A plurality of first and second fluid flow channels are formed between the heat exchanger plates for first and second fluids respectively, and first fluid and second fluid chambers are formed in the stack in communication with the first and second fluid channels respectively. An end plate for the heat exchanger has 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. A planar reinforcing plate is 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.
