ABSTRACT:
A heat exchanger in accordance with the present invention transfers heat between first and second fluids (36 and 60) flowing transversely with respect to each other through a heat exchanger core (30) which is formed from a stack of a plurality of heat conductive first and second plates (32 and 34) with at least one first plate partially defining at least one first channel (55) and at least two plates each having at least one fluid orifice within each second channel (58). Each first plate comprises first and second slots which each extend through the first plate to form a passage, each first slot (52) extending across the first plate to opposed peripheral sides of the first plate and each second slot (59) extending across the first plate and not to the opposed peripheral sides. Each first slot is contained in a different first channel with the opposed peripheral sides respectively being disposed on different faces of the core and each second slot is disposed within a different second channel.
