Abstract:
1. An apparatus for temporarily assembling a heat exchanger, comprising: a support member having a support surface with opposite side portions, the support member being configured to support, on the support surface, a plurality of heat exchanger tube blanks positioned in parallel to one another and extending in a longitudinal direction such that the heat exchanger tube blanks each have an end portion extending beyond a respective side portion of the support member and aligned with the end portion of an adjacent heat exchanger tube blank; a plurality of header supports configured to support headers, the header supports being positioned longitudinally outward of respective opposite side portions of the support member and movable with respect to the support member in the longitudinal direction; and a plurality of tube blank correcting members configured to correct dimension of the heat exchanger tube blanks, each of the tube blank correcting members having a plurality of blank fitting slits formed along a side edge thereof at a spacing corresponding to a spacing of heat exchange tubes of the heat exchanger, wherein each of the tube blank correcting members is movable between a correcting position and a noncorrecting position such that, when the tube blank correcting member is at the correcting position, the end portions of the heat exchanger tube blanks are fitted into the blank fitting slits, and when the tube blank correcting member is at the noncorrecting position, the heat exchanger tube blanks are not fitted into the blank fitting slits, and the tube blank correcting members are movable in the longitudinal direction of the heat exchange tube blanks from the end portions toward center portions of the heat exchange tube blanks such that the headers supported by the header supports are connected with the end portions of the heat exchanger tube blanks.
