Tube blank correcting member for use in temporarily assembling heat exchanger, and apparatus for and method of temporaily assembling heat exchanger

A heat exchanger temporarily assembling apparatus for use in fabricating a heat exchanger comprising a pair of headers arranged in parallel and spaced apart from each other, a plurality of flat heat exchange tubes arranged in parallel between the headers and brazed at opposite ends to the respective headers with the tube ends placed into respective insertion holes formed in the headers, and fins each arranged between and brazed to each pair of adjacent heat exchange tubes, the apparatus being adapted for use in temporarily assembling the headers, flat heat exchange tube blanks and the fins into a unit to be brazed,

• the heat exchanger temporarily assembling apparatus comprising a support member for supporting thereon the heat exchanger tube blanks arranged from front rearward in parallel with their lengthwise direction positioned laterally, with their widthwise direction positioned vertically, and with opposite left and right ends thereof aligned respectively, and the fins arranged between the respective pairs of adjacent tube blanks, two header supports arranged respectively at left and right sides of the support member and movable leftward or rightward, and a pair of left and right tube blank correcting members each extending from the front rearward and having a plurality of blank fitting slits formed in a side edge thereof and arranged from the front rearward at the same spacing as the heat exchange tubes to be produced of the heat exchanger, each of the tube blank correcting members being movable between a correcting position wherein the corresponding ends of all the tube blanks as supported on the support member are fitted into the respective slits and a noncorrecting position wherein the tube blanks are not fitted into the slits.
