A heat exchanging apparatus is described comprising, substantially parallel heat transfer elements each having a longitudinal axis in a plane perpendicular to the normal direction of fluid therethrough; a source of a fluid having lint particles and moving in a flow direction; means for supporting the heat transfer elements for intercepting the moving fluid for heat exchange in the flow direction having a major component substantially perpendicular to the plane; the fluid having lint particles which if allowed to accumulate would clog the heat exchanging apparatus and obstruct the flow of the fluid; each heat transfer element having fin means extending radially outward from an element longitudinal axis for increasing the heat transfer between the fluid and each heat transfer element; means for rotatably supporting each of the heat transfer elements; means for producing fluid flow; and means for slowly continuously rotating the heat transfer elements.
