A plate type evaporator having heat transfer surfaces with which jets of liquid collide. Each heat transfer surface is formed with a number of grooves arranged in concentric circles with their common center located at the center of collision. Such grooves, on the boiling heat transfer surfaces, function to promote the formation of nuclei, while on the heating heat transfer surfaces, they act to cause turbulent flow to the heating medium in that they constitute points of contacts where they are contacted with the bottoms of the grooves of an adjacent heat transfer plate. |
