ABSTRACT:
A plate heat exchanger comprises a plurality of heat exchanger plates stacked one above the other. The plates each have a peripheral edge projecting from its plate plane. The heat exchanger plates succeeding one another in each case are sealingly connected at their edges, so that flow ducts for at least two heat exchange media form between the plates. Each of these flow ducts is connected via openings in the heat exchanger plates to at least one other flow duct, so that a first heat exchange medium can flow through a first group of ducts loaded in parallel and a second heat exchange medium can flow through another group. So that a heat exchanger constructed in this way offers a satisfactory heat transmission capacity even in the case of widely varying volume flows of the media involved, the openings for the first heat exchange medium have a substantially larger cross section than the openings for the second heat exchange medium.
