Abstract

A plate heat exchanger is composed of a number of plate elements each of which comprises two thin nested plates, the elements defining flow spaces between them, adjacent elements being joined around their periphery by brazing bent edge portions, there being brims extending from the edge portions of each plate element, each brim being spaced from the brims of adjacent plate elements.
