When chute of plate from wet side is from above, perforation for liquid is on side forming reservoir for wetting opposite wick materials. When flow move along dry side, heat is conveyed to plate. In proposed method several heat transfer plates are used. Said plates have wet and dry sides and they form chutes. Plates are wetted form wet sides with evaporating liquid and they pass separately two flows, namely, working and product ones through dry sides. Flow of working gas passes along dry side and gets through perforation into channels on wet side which is cooled owing to evaporation, thermal conductivity of plate and its heat radiation.
