ABSTRACT:
A heat exchanger includes a pair of header pipes spaced a predetermined distance away from each other, a plurality of tubes connected between the header pipes for defining flow paths for a heat exchanging medium and a plurality of fins installed between the tubes for radiating heat from the heat exchanging medium. Each of the header pipes includes a flat bottom portion formed with a plurality of apertures for receiving the plurality of tubes, a pair of vertical walls extending from both side ends of the flat bottom portion and having a plurality of grooves corresponding to the apertures for guiding the tubes, and curved portion extended from the walls and forming a hollow inner space by joining both side edges thereof. The header pipe is manufactured by forming a bottom and a pair of walls approximately perpendicular to the bottom at the side ends of the bottom by bending a sheet member coated with a cladding layer, forming a plurality of apertures for receiving a plurality of tubes in the bottom and a plurality of grooves for guiding the tubes and extending from the apertures in the walls, forming a curved portion by bending both side edges of the vertical walls, and joining the side edges of the curved portion by brazing.
