A STRUCTURE FOR THE END OF PRESSURE VESSELS, MOST APPLICABLY PLATE HEAT EXCHANGERS, FOR REDUCING THE EFFECTS OF MOVEMENT CHANGES AND VIBRATIONS CAUSED BY VARIATIONS IN INTERNAL PRESSURE AND TEMPERATURE, A METHOD FOR IMPLEMENTING IT AND USE OF SAME

摘要

The object of the invention is a structure for the end of pressure vessels, most applicably plate heat exchangers, for reducing the effects of movement changes and vibrations caused by variations in internal pressure and temperature. What is essential in the invention is that the end is made up of a heat transfer plate 1 and an end part 3 in such a way that the end part 3 is connected by welding to the shell of the outer surface of the heat exchanger stack 8, forming an enclosed chamber 5 on the end of the heat exchanger, into which chamber 5 higher pressure 7 than the external pressure level is brought and/or generated, which higher pressure receives and dampens, via a heat transfer plate 1, vibration and pressure shocks harmful to the heat exchanger structure in the medium circuits of the heat exchanger.
