Abstract
The present invention constitutes a plate heat exchanger for three heat exchanging fluids. The heat exchanger includes at least one core of plates with heat exchanging plates (1-4), at least two end plates (5) and inlets and outlets (6) for the heat exchanging fluids, each one of the heat exchanging plates (1-4) being provided with six port holes (11-16). The plate heat exchanger has port holes (11-16) that are pairwise aimed for the flowing through of the respective heat exchanging fluids where the port holes (11-16) in every such pair are situated on both sides of a heat transferring part in such a way that a straight line drawn between the centers of the port holes (11-16) divides the heat transferring part into two similar parts. The invention is also directed to a plate heat exchanger for refrigeration applications, in which the port holes (17, 18, 20, 21, 23, 23', 24, 24') for each one of the two fluids create at least two inlet channels through the core of plates which, for each one of the fluids, are in fluid communication with each other at a plurality of places along the inlet channels in such a way that the fluid, on its way from the one inlet channel to plate interspace…
