The winding chain dissipating unit has a winding chain outer tube, a winding chain inner tube, and heat pipe within the winding chain inner tube. The inner diameter of the winding chain outer tube is matched with the outer diameter of the winding chain inner tube so as to have a smaller front end and a larger rear end. Moreover, an elastic element is installed at a position between the front end of the winding chain inner tube and the front wall of the winding chain outer tube so that the winding chain inner tube generates a continuously front pulling force to the winding chain outer tube. Once a wear from rotation friction therebetween is formed, the winding chain inner tube will move forwards gradually so as to automatically adjust and compensate the gap from the wear.
