<p>The invention relates to a plate heat exchanger comprising a plurality of plates, each extending in parallel with a main extension plane (p), and at least one adapter plate (3). The heat exchanger plates (2) form a plate package with first plate interspaces (6) for a first medium and second plate interspaces (7) for a second medium, wherein each of the heat exchanger plates has four port holes (8) which form ports extending through the plate package and wherein the adapter plate (3) is provided outside one of the outermost heat exchanger plates (2',2"). A distance plate (13) is arranged between said adapter plate (3) and a respective one of the outermost heat exchanger plates (2',2"), said distance plate (13) comprising at least two port holes (14 which are concentric with each of the respective port holes (8) of the outermost heat exchanger plates (2',2") and the adapter plate (3) and where the port holes (14) of the distance plate (13) are larger than the port holes (8) of the outermost heat exchanger plates and the port holes (8) of the adapter plate (3), respectively.</p> |
