Heat exchanger of air conditioner

Abstract

The present invention relates to a heat exchanger of an air conditioner having a plurality of flat fins, each arranged in parallel at a predetermined interval to allow fluid to flow thereamong and a plurality of heat transfer pipes insertedly arranged in perpendicular patterns to the plurality of the flat fins to allow the fluid to internally flow, the heat exchanger comprising a plurality of louvered grid groups symmetrically opened in a forward and a reverse flowing direction of air current and radially disposed to encompass an upper and a lower side of the heat transfer pipes, so that the air current flowing though the plurality of flat fins can become turbulent and mixed around the heat transfer pipes to thereby reduce a cavitation region generating at the back of the plurality of heat transfer pipes and concurrently to increase a heat transfer efficiency, the heat exchanger further having an advantage in that a bead part is bent toward an inner side of the flat fin so as to be centrally and perpendicularly positioned at the louvered grid groups against the upper and lower sides of heat transfer pipes, so that superficial area of the flat fin can be enlarged and concentrated water (by way of example, dew) generated by temperature difference between the refrigerant flowing in the heat transfer pipes and the air current flowing through the flat fins can be smoothly drained out when the beat exchanger is used as an evaporator for cooling or as a concentrator.
