Plate type heat exchanger

Abstract

Abstract PURPOSE: To utilize a heat transfer plate itself as a reinforcing member in a plate type heat exchanger by forming a wavy header portion at the heat transfer plate and forming to surround the header portion by an wavy surface making low pressure fluid passage contact with the raised top and rcessed bottom of a high pressure fluid passage. CONSTITUTION: A heat transfer plate 13 incorporates semi-circular wavy surfaces 4 formed at projected and recessed portions of no lateral phase displacement. In order to produce a heat transfer plate pair with two heat transfer plates, the projected top portion 15 and the recessed bottom portion 16 of the wavy surface make close contact with the top 15 and bottom 16 of other heat transfer plate obtained before reversing it upside down. Both lateral ends of the heat transfer plates are continuously sealed at both ends between the transfer plate pair and the transfer plate, sealing plate 21 by a sealing plate 22 longitudinally to thereby longitudinally continuously seal between one heat transfer pair and other transfer plate excluding fluid inlet and outlet portions from inlet and outlet headers 18 and 19.
