Abstract
Space and weight constraints on heat exchangers performing heat exchange operations between three or more fluids are eliminated in a structure including a plurality of plates (10, 12) arranged in a stack (13). Collars (36, 38) about openings (30, 32) the plate (10, 12), divide the spaces between the plates (10, 12) into two different types of spaces (44, 46). A connecting flange (50) with a tube (46) and a separator element (64) cooperates with holes (54) and (56) within the plates that (10, 12) to isolate certain of the spaces (44) from other of the spaces (44) providing a means for flowing different heat exchange fluid through different ones of the spaces (44) while flowing still another heat exchange fluid through the spaces (46), all in a single structure.
