REFRIGERATOR EVAPORATOR

摘要

PURPOSE: A refrigerator evaporator is provided to reduce manufacturing time and cost for evaporator by allowing frost to be uniformly deposited all over the surface of the evaporator. CONSTITUTION: A refrigerator evaporator comprises a plurality of heat transfer pipes(11) spaced apart from each other and horizontally parallel, with respect to the air flow direction; and a plurality of heat transfer fins(13) having a plurality of through holes for passage of heat transfer pipes, and which are coupled to heat transfer pipes in such a manner that heat transfer fins are spaced apart from each other to be parallel with the air flow direction. Each of heat transfer fins includes a hydrophilically treated surface area(19c) where a plurality of hydrophilically treated heat transfer fins having different surface tension are disposed, and a hydrophobically treated surface area(19a) where a plurality of hydrophobically treated heat transfer fins are disposed.
