Abstract (en)
[origin: WO0148433A1] The present invention refers to a plate heat exchanger for at least two heat exchanging fluids which heat exchanger is permanently joined and comprises at least one core of plates with a plurality of heat exchanging plates (2a, 2b) and at least two end plates (3, 4) the heat exchanging plates (2a, 2b) creating plate interspaces between each other. Each one of the heat exchanging plates (2a, 2b) is provided with one or several corrugations and at least four port holes (9, 10, 13, 14) being parts of an inlet channel (11) and an outlet channel (12) through the core of plates for each one of the fluids. The inlet channels (11) and the outlet channels (12) for a first and a second fluid respectively are in fluid communication with a first (17) and a second (18) set of plate interspaces respectively. At least two of the said and next to each other situated heat exchanging plates (2a, 2b) in the present core of plates is each one provided with at least one trough-shaped section (19) which each one in cooperation with the respective adjacent heat exchanging plate (2a, 2b) creates a space which is sealed towards all fluids except a second fluid and which each one constitutes a part of the respective heat exchanging plate (2a, 2b) in such a way that the said part lacks port holes (9, 10, 13, 14) and that each one is made with a flangelike edge (22) extending around the hole circumference of the trough-shaped section (19).
