ABSTRACT:
A tube expander for heat exchangers is capable of organizing an ideal production line where the transportation efficiency is increased and the productivity is improved by having a transportation path in a straight line through which the heat exchangers are carried into one end and carried out from the other end. Left and right ends of an end plate at the front side are inserted by a pair of first guide bars, and the left and right ends at the back side are inserted by a pair of second guide bars. A guide path for a carrying device or a transportation device is established on a base that supports the first guide bars and the second guide bars in a clearance between the first guide bars and support columns. The heat exchangers are transported from one end to the other of the base via the guide path.
