  • Patent number: 5470431
    Abstract: A stack type evaporator includes tubular elements 1 each having a plurality of inwardly protruding recessed ribs 7 which extend from an upper header portion 1a of the element to a lower header portion 1b, with the ribs serving as straight drainage canals 7a of specified width and area. A hydrophilic resin coating of a specific composition covers the outer surfaces of the tubular elements 1 and fins 2 each interposed between two adjacent tubular elements. The combination of straight drainage canals, the specified width and area thereof and the specific hydrophilic resin coating is effective to facilitate the drainage of condensed water so that the waterdrop is substantially prevented from flying out of the evaporator, and the hydrophilic coating itself does not emit any unpleasant smell.
