Abstract
A header pipe 3 is prepared by severing an elongated round pipe to a desired length, forming an engagement recess 1 in the inner surfaces at opposite open ends, and forming a multiplicity of flat holes 2 in the peripheral surfaces. A flat tube 4 is inserted into each of the flat holes 2, with fins 5 fixedly secured to the outer surfaces thereof to thereby construct a core 6. End members such as the end portion of a port pipe 7 and an end cover 8 are fitted to the openings of the header pipe 3 by way of an O-ring 9 for sealing, to complete a module-type heat exchanger.
