PURPOSE: A heat exchanger is provided to improve the heat transfer performance of the heat exchanger as the air flowing along the outside of the heat exchanger becomes the warm current due to the shape of the tube. CONSTITUTION: A heat exchanger comprises a header tank, a tube, and a divergent tank. A pair of header tanks(10) with a flow channel in which a heat exchange medium flows is installed at the upper stream and the lower stream of the air flowing direction. A tube(30) is formed in the air flowing direction. The both ends of the tube are fixed on the divergent tank(20) and the heat exchange medium flows from the header tank. The heat exchange medium circulates in the opposite direction to the air stream direction. |
