ABSTRACT:
The present invention provides an assembling apparatus for a heat exchanger, which is capable of certainly coinciding ends of pipes with pipe holes of fins so as to easily insert the pipes into the pipe holes. In the apparatus, a send-in section sets the stack pin holders at predetermined positions and is capable of keeping the stack pins extending upward. A plurality of supporting sections vertically hold the pipes whose U-bent sections are located at the uppermost position. A pipe inserting section has a plurality of holders, which are capable of receiving the pipes from the supporting sections to hold, and a plurality of inserting dies for pushing the pipes downward. A guide section is provided above the send-in section and has a plurality of guide holes into which the pipes pushed by the inserting dies are inserted. The guide holes are capable of limiting outer width of the pipes by at least inner faces and introducing the pipes into the pipe holes of the fins.
