Plate type condenser
 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.
