Patent ID: 7188492

Claim:
A plate heat exchanger for indirect heat exchange between at least one heat transfer medium/cooling medium and a plurality of fluid flows comprising: a heat exchanger core having a plurality of heat exchange passages for flow of at least one heat transfer medium/cooling medium, flow of a first fluid, and flow of a second fluid, wherein the heat exchange passages for the flows of said at least one heat transfer medium/cooling medium, said first fluid, and said second fluid run parallel to one another, said heat exchanger core ( 9 ) having a first component area and a second component area, said first component area containing heat exchange passages for the first fluid flow ( 40 ), and said second component area containing heat exchange passages for the second fluid flow ( 30 ), wherein said first and the second component areas are not in fluid communication, and said first and second component areas each extend over the height of the heat exchanger core ( 9 ) and said passages of said first and the second component areas are rectilinear over the height of said heat exchanger core, the height of the heat exchanger core ( 9 ) being its extension in the direction of the main flow through the heat exchange passages, and each of said first and second component areas extends over only part of the width of the heat exchanger core.
