ABSTRACT:
A tube expander having a tube expander body, a reciprocable member to be reciprocated with its surface facing a tube to be expanded which is mounted in a heat exchanger unit, and a mandrel mounted on the reciprocable member so as to be inserted into the tube for the expansion thereof. A support fixture, on which the heat exchanger unit is separably mounted, is movably mounted on a mounting table which is disposed towards the moving direction of the mandrel such that the support fixture is transported on the mounting table in the transverse direction relating to the moving direction of the reciprocable member. A holding mechanism is provided on at least one of the mounting table and a peripheral area thereof so as to hold the support fixture or the heat exchanger unit mounted thereon, introduce the heat exchanger unit with the tube to be expanded into a tube expanding area, and discharge the heat exchanger unit from the tube expanding area after expanding the tube thereof.
