Plate heat exchanger and double-walled heat exchanger plates, with single-wall

摘要

The present invention relates to a plate heat exchanger (20) with a stack (21) of heat exchanger plates, which are connected permanently to one another and between which separate through flow spaces for at least two heat exchangers - fluids are formed. Is a part of the heat exchanger plates in each case as a single-walled heat exchanger plate with a plate element, whereas another portion of the heat exchanger plates in each case as a double-walled heat exchanger plate is designed with two plate elements.
