IPC: F28F9/04
Filed: 1990-03-07
Abstract: PURPOSE:To markedly enhance workability by holding the end parts of a heat exchange tube by notches in a process bending a material becoming a header pipe into a tubular shape and correcting the position of the heat exchange tube even where there is slight positional shift between the heat exchange tube and the notches. CONSTITUTION:Notches Ka each having the U-shape corresponding to the half shape of the cross-section of each of heat exchange tubes 2 are respectively formed to the opposed end parts of materials K in the lateral direction thereof at the interval coinciding with the arrangement interval of the heat exchange tubes 2. After each heat exchange tube 2 and the notches Ka are roughly aligned, the material K is further bent into a circular tube shape and the end parts of each heat exchange tube 2 are held by the notches Ka in this bending process. Even when there is slight positional shift between the heat exchange tube 2 and the notches Ka, the position of the heat exchange tube can be corrected in the same process by utilizing the guide surfaces 2a of the heat exchange tube 2.
