ABSTRACT:
A heat transfer device comprising a spiral brush insert within a tube of rmally conductive material. The brush insert has a diameter slightly larger than the inside diameter of the tube and is inserted from the downstream end of the tube so that the tips of the brush deflect to form a friction fit for imbedding within the tube wall and thereby prevent movement of the brush insert during normal fluid flow in the device.
