Abstract:
A condenser comprising:at least one heat transferring face formed of a plate-shaped material, and having opposite surface sides structurally arranged so that a change of phase of a low temperature fluid from a liquid phase to a gaseous phase is made by causing a high temperature fluid and the low temperature fluid to flow respectively on said opposite surface sides of said heat transferring face, respectively, so that flowing directions of said high and low temperature fluids are perpendicular to each other, to achieve a heat exchange between said fluids, at least one condensate discharging trough portion formed from a side edge of said heat transferring face having a first groove portion formed on a surface of the high temperature fluid side of said heat transferring face so as to extend in an oblique direction to a flowing direction of the high temperature fluid by a prescribed angle, said at least one condensate discharging trough portion being capable of receiving condensate of the high temperature fluid, which is generated on the heat transferring face to flow down in the flowing direction of the high temperature fluid; andwhere said heat transferring face is divided into a plurality of zones by said at least one condensate discharging trough portion and said zones have prescribed patterns of irregularity, said prescribed patterns of irregularity appearing on at least high temperature fluid side.
