Plate used in condenser

A plate for use in a condenser, said plate including condensate collecting and discharging elements, said condensate collecting and discharging elements comprising a plurality of V-shaped inclined grooves downwardly sloped towards a central portion of said plate, and a vertical groove formed along said central portion of said plate connecting with a lowest portion of each of said inclined grooves, wherein said inclined grooves form ramps leading to said vertical groove and said vertical groove forms a recessed channel, said condensate collecting and discharging elements further comprising a plurality of alternating longitudinal grooves and valleys, lower ends of said valleys opening towards said downwardly sloped inclined grooves, whereby said inclined grooves and said vertical groove minimizes the area of a filmy downflow liquid layer and prevents a film from growing too thick, thereby improving the heat transfer surface of said plate.
