A plate type condenser with a plurality of heat transmitting plates assembled face-to-face to form therebetween passages for steam and the cooling liquid alternately. The plate has in a heat transmitting surface, on which condensate occurs successively, a plurality of longitudinal grooves which serve for subjecting the condensate to flow down only in the grooves under the action of surface tension, and a condensate collecting and discharging means consisting of inclined grooves and vertical grooves, for the purpose of preventing the downflow liquid layer on the heat transmitting surface from its growth. The longitudinal groove is curved at the lower portion thereof along the inclination of the inclined groove, and the inclined groove is in the multi-stripes configuration to improve the condensate collecting and discharging performance. Decrease in pressure loss of steam is also accomplished in addition to the advance of the condensate discharging performance by constructing the inclined groove in the form of weir with a weir plate which is provided on the steam passage side thereof with a plurality of overhangs opening in the direction of the stream of steam. |
