ABSTRACT:
An automated heat exchanger tube expander includes an automatically adjustable tool stop, an automatically adjustable back support, and a universal base support. The adjustable stop, the back support, and the base support function together to facilitate the manufacturing of various size tube and fin heat exchangers. The automatic tube expander avoids the time consuming set up for each different size heat exchanger normally required by manual tube expanders.
