Abstract

The heat exchanger of the air conditioner according to the present invention includes a plurality of flat fins 1 arranged in parallel at regular intervals such that air flows therebetween, and at a right angle to the plurality of flat fins 1 so that fluid flows therein. In a heat exchanger of an air conditioner composed of a plurality of inserted heat pipes (2), the flow of air flow flowing to the rear surface and the surface of the plate fin (1) is turbulent and mixed to the rear of the plurality of heat pipes (1) Stepped type covering the upper and lower circumferences of the heat transfer pipe 2 while opening the plate fin 1 in the flow direction of the air flow with respect to the upper and lower sides of the heat transfer tubes 2 to reduce the exponential area generated and improve the overall heat transfer performance. It is characterized by having a plurality of louver type season group, it is possible to turbulent and mixing the flow of the air flow to increase the heat transfer effect and at the same time the heat transfer pipe (2) It is possible to effectively reduce the exponential region occurring at the rear side, and to improve the heat transfer in the center between the plurality of heat transfer tubes 2 while allowing the heat transfer from the heat transfer tubes 2 to be smoothly transmitted without blocking the flow of heat. It is.
