A heat exchanger is provided to form headers in the oval shape to be protruded in the opposite direction from tube insertion direction for assuring spaces parts for flux applying between radiating fins and the headers, thereby carrying out the flux applying work between tubes and the headers and between tanks and the headers simultaneously, wherein ribs of the headers prevent deformation of the headers and promote smooth flow of heat exchanger fluid. A heat exchanger includes headers(20), wherein a bottom plate of the header is formed in the oval shape with a center protruded in the opposite direction from tube insertion direction, so that space parts are formed between the header and radiating fins(31) to simplify flux applying work for coupling surfaces between tubes(30) and the header. The bottom plate is formed with a plurality of tube insertion holes(21) and ribs(23) protruded in the tube insertion direction between the tube insertion holes. |
