Abstract
A heat exchanger includes an insert having a plurality of longitudinal flutes disposed about its periphery defining flow passages of enhanced surface area. The insert includes at least one slot and expansion means so that the insert can be inserted into a duct without press fitting and subsequently expanded to urge the flutes into intimate thermal contact with the wall of the duct. Removal of the expanding force permits the insert to be removed from the duct for maintenance.
