Abstract

PURPOSE:To reduce the resistance to two-phase fluid flow of a medium to be evaporated, by forming medium fluid passages and heating fluid passages alternately between heat exchanger plates which are arranged vertically and in parallel with each other, and disposing a corrugated plate formed with hollows at its ridge portions in each of the medium fluid passages. CONSTITUTION:Liquid passages 10 for passing a medium liquid 6 therethrough and heating fluid passages 11 for passing a heating fluid 19 therethrough are formed alternately between heat exchanger plates 9 which are arranged vertically and in parallel with each other. Further, a corrugated plate 13 is disposed under a trough 12 provided in each of the liquid passages 10. Here, arrangement is such that ridge portions 13a of the corrugated plate 13 are located near to the wall 9a of the liquid passage 10 and a proper number of hollows 14 are formed at the ridge portions 13a along the width of the plate 13 with proper intervals from each other. Vapor passages 17 surrounded respectively by liquid film flows 6a, 6b are formed under the trough 12 and the corrugated plate 13.
