Abstract
The invention relates to a plate heat exchanger in which the heat exchanging plates are brazed together along the periphery (17) of the exchanger and around port holes (2′,4′) in neighboring plates to prevent that the heat exchanging flows mix when flowing through port channels comprising said port holes (2′,4′). In order to facilitate draining of heat exchanging media from the exchanger and in order to obtain better exploitation of the heat exchanger volume the sealing of neighboring plates around port holes may according to the invention be effected in different plans (24, 25).
