ABSTRACT:
A heat exchanger for an air conditioner having a plurality of parallel heat exchanging tubes passing through flat fins perpendicular thereto, the flat fins being arranged in parallel to each other at predetermined intervals, and each heat exchanging tube having fluids flowing inside therethrough, the heat exchanger comprising a plurality of louvers radially arranged around the tube, each louver being opened in flow direction of the air currents, such that the air currents flowing into the front and rear surfaces is turbulent around the tube, and first and second beads formed, respectively, before and behind the heat exchanging tubes in flow direction of the air currents, thereby enlarging a whole surface area of the flat fins, and reinforcing the flat fins, by which there is provided the turbulence and mixture of the air currents, further improving the heat transfer effect and reducing the air dead region around the heat exchanging tube. Also, the continuity of the heat transfer from the tube into other places can be guaranteed, with the improved heat transfer. Moreover, the beads provide the enlargement of the surface area of the flat fin and improved reinforcing thereof.
