Abstract
A condenser comprises at least one heat transferring face formed of a plate-shaped material. 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 on opposite surface sides of the heat transferring face, respectively, so that flowing directions of the high and low temperature fluids are perpendicular to each other, to make a heat exchange. There is provided at least one condensate discharging trough portion having a first groove portion formed on a surface of the high temperature fluid side of the heat transferring face so as to extend in an oblique direction to a flowing direction of the high temperature fluid by a prescribed angle. The condensate discharging trough portion is 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. The heat transferring face is divided into zones by the condensate discharging trough portion. The zones have prescribed patterns of irregularity appearing on at least high temperature fluid side.
