APPARATUS FOR RADIATING HEAT OF HEAT EXCHANGER

摘要

PURPOSE: An apparatus for radiating heat of a heat exchanger is provided to improve heat exchange rate by improving shape of a fin to prevent concentration of frost. CONSTITUTION: A fin(110) has winding parts(111) wound zigzag at regular intervals. Louvers(113) are formed on plane parts(112) formed between the winding parts, and bent at fixed angle to expand heat transfer area of the fin. The louver is cut away symmetrically centering on a center of the plane part. A louver central surface is formed on the center of the plane part to be inclined only to one side so as to prevent collection of condensed water. Louver surfaces are symmetrically formed on both sides of the louver central surface, and inclined upward and downward. The fin is mounted to a tube(2) so that a front protrusive part(114) is protruded from width of the tube by 5-15mm in a direction in which air flows, and a rear protrusive part(115) is protruded from the width of the tube by 3-10mm in a direction opposite to the direction in which air flows.
