Abstract
The present invention relates to a plate heat exchanger comprising several heat exchange plates arranged between two end plates (30), at least one of which has through-ports (31) and a side surface (36) facing the heat exchange plates, which is unmachined around the ports (31). At least one of said ports is provided with a cover (32) preventing through-flow. According to the invention said cover (32) is applied against the side surface (36) of the end plate (30) facing the heat exchange plate, and comprises at least two cooperating parts, a first thin part (33) abutting said side surface (36) and a second thick part (35) mainly placed within and essentially covering said port (31). Said first part (33) is dimensioned to withstand shearing forces and said second part (35) is dimensioned to withstand bending forces acting on the cover (32) as a result of an internal pressure in the plate heat exchanger.
