A condenser having heat transmitting surfaces, which comprises two types of heat transmitting plates alternately arranged side by side to define alternate passages for cooling liquid and steam so that the steam is condensed on the heat transmitting surfaces on the steam passage side. The heat transmitting surfaces are formed with grooves and ridges which are recessed in and raised above the base surface, thereby providing a condensate discharging mechanism comprising vertical grooves and inclined grooves for each given region on the condensating and heat transmitting surfaces, and longitudinal grooves are formed between the inclined grooves of said condensate discharging mechanisms.
A rectilinear plate type condenser construction comprising two types of heat transmitting plate elements arranged in side by side relationship to define alternate passageways therebetween, one passageway being for the passage of a cooling liquid therethrough and the other for the passage of steam therethrough in countercurrent flow to the cooling liquid so that the steam will be condensed on the heat transmitting surface of the steam side of one of the transmitting plate elements, each of said plate surfaces having a plurality of first vertical channels extending in right angle relationship to the top edge of the plate element and in widely spaced, lateral relationship to one another formed thereon, a plurality of vertically spaced, inclined channels formed therein between said first channels with the lower end of each of said inclined channels merging into at least one of said first vertical channels, and a plurality of laterally spaced second vertical grooves formed thereon between each of said first widely spaced vertical channels in parallel relationship thereto, said plurality of second vertical channels extending between and connecting one inclined channel to the next succeeding inclined channel, said vertical and inclined channels forming a condensate discharging means for each given region on each of the condensing and heat transmitting plate surfaces of each plate element.
