<p>Plate heat exchanger comprising heat exchange plates mounted between a frame plate and a pressure plate, the frame plate and the pressure plate having ports lined with linings for intake and outtake of media that shall be heat exchanged and the heat exchange plates having ports in alignment with corresponding ports in the frame plate and the pressure plate round which ports of the heat exchange plates extend ring gasket grooves, each ring gasket groove having a rear side and a front side, the front side of the groove being that one where the ring gasket is intended to be placed. According to the invention that one of the frame plate or the pressure plate (1) facing the rear side of the ring gasket groove (4) of the heat exchange plates is provided with linings (2; 14; 22; 23) which do not require machining of the plate (1) at the area of the ports and that the sealing between the lining (2; 14; 22; 23) and a heat exchange plate (3) is brought about by means of a ring gasket (5; 21) interfering into the ring gasket groove of the heat exchange plate (3) positioned closest to the frame plate or the pressure plate (1).</p> |
