Apparatus for positioning pin fins of a finned-tube heat exchanger

摘要

An apparatus for contacting and bending preselected pin fins of a finned-tube heat exchanger to preselected locations. First and second toothed wheels positioned on opposed sides of respective first and second pin fin rows bend the pins in response to moving a finned tube through a base opening. A wheel contacts the finned tube between the rows of pin fins and urges the tube into forcible engagement with a base.
