A gas/liquid heat exchanger includes a stack of abutting, substantially identical plates that are arranged in alternating fashion to define first and second flow channels. End plates are placed on the stack of the aforementioned plates. The core allows straight through flow of gas in the first fluid passageways which may be made relatively large and the use of a cooling liquid flow through the second coolant passageways for cooling the gas in the first coolant passageways.

[ We claim:] [1.]1. A gas/liquid heat exchanger comprising:a stack of abutting, substantially identical plates with there being first, second, third, fourth, . . . nth plates where "n" is an even integer of four or more;each plate being generally channel-shaped having a base with spaced sides and spaced ends extending between said spaced sides, upstanding legs on said base, each leg extending along a corresponding side and being of equal height, each leg terminating in a flange that is generally parallel to said base, each base including a central platform of raised height less than the height of said legs and spaced inwardly of said ends and said sides so as to be surrounded by a band of said base;said plates being stacked in the order 1, 2, 3, 4, . . . n in alternating fashion with the flanges on the first and second plates in abutment, the flanges on the third and fourth plates in abutment . . . and the flanges on the n-1 and the nth plate in abutment, and with the bands on said second and third plates in abutment . . . and the bands on the n-2 and n-1 plates in abutment;whereby first flow channels exist between said first and second plates, said third and fourth plates . . . and said n-1 and nth plates, and second flow channels exist between the central platform of said second and third plates . . . and said n-2 and said n-1 plates;two side plates, one on each of two opposite sides of said stack;first and second ports in said heat exchanger at opposite ends of said plates to be in fluid communication with said first flow channels; andthird and fourth ports in one or the other or both of said side plates and in fluid communication with said second flow channels.
