Evaporator and condensate collector arrangement for refrigeration apparatus

Claim 1

An evaporator coil assembly for use in an air conditioning system of the type in which the evaporator coil assembly is located within a plenum through which air to be conditioned is forced under positive pressure through said coil assembly comprising: an evaporator coil including a plurality of tube sections extending in at least two planes perpendicular to the direction of air flow; a plurality of substantially vertically arranged plate-like fins each lying in a plane parallel to the direction of air flow and being in heat exchange contact with substantially all the tube sections traversing said plane, each said fin having a straight upper edge perpendicular to the air flow and a lower edge providing V-shaped tapered portions with the apex thereof arranged at the lowermost condensate discharge point of each fin; a plurality of spaced parallel condensatecollecting troughs supported on said cabinet in said passage and extending substantially the length of said coil portions of said evaporator, said troughs underlying said V-shaped tapered portions of said fins and each trough having a width to underlie only the condensate discharge points of the adjacent fins to collect condensate gravitating from the fins while reducing interference with the flow of air through said passage to a minimum.
