Abstract:
A plate heat exchanger comprising:heat exchanger plates arranged adjacent to each other and in a compressed pack, the heat exchanger plates each having openings aligned from one heat exchanger plate to another heat exchanger plate so as to define channels configured to receive a heat emitting medium and a heat absorbing medium alternately in said channels via said openings; andgaskets arranged in gasket regions on a periphery of said openings and between the one heat exchanger plate and the another heat exchanger plate wherein;the heat exchanger plates have corrugations extending from the openings in a substantially radial direction and uninterrupted through the gasket regions,hills and troughs of the one heat exchanger plate and the another heat exchanger plate cross at crossing points such that said one heat exchanger plate and said another heat exchanger plate support each other at the crossing points,each gasket is flanked by the crossing points,each gasket is arranged between said at least two adjacent heat exchanger plates and varies in cross-section so as to be adapted to a profile of the heat exchanger plates, anda substantially same gasket pressure is obtained over an extent of each gasket in a compressed condition.
