The invention relates to an arrangement in a plate heat exchanger (1). Between the plates are flow channels, every other one of which is designed to receive the flow of a heat-emitting medium and every second one of which a heat-absorbing medium. The flow channels for one of the media, preferably the heat-absorbing medium, are connected in parallel via inlet and outlet ports to manifolds for the said medium. In one section on two opposing sides an opening (9') with a side wall (10) running round the edge (9'') of the opening and inclined somewhat inwards is made in the plates. The said side wall has an interruption (10') so that, with the side walls (10) of the plates telescoped in one another and connected pressure-tightly with one another by a joining process the side walls (10) form walls of the manifolds (8, 9) and the side wall interruptions (10') form inlet and outlet ports (10'') between the manifolds (8, 9) and the flow channels. |
