Winding heat exchanger heat exchange tube clearance controlling means of activity

The utility model discloses a clearance controlling means of the winding heat exchanger heat exchange tube of activity, including filler strip and spiral winding silk, its characterized in that, does the filler strip have 10 by what the steel sheet cut the billet of 20mm width, round steel or steel wire can be adopted to the spiral winding silk, and the horizontal welded fastening of spiral winding silk fixes the spiral winding silk of certain length according to the design clearance of heat exchange tube on every filler strip on the filler strip. The diameter of spiral winding silk equals the intertube crack of heat exchange tube, and filler strip thickness equals the lamellar spacing of heat exchange tube, and the length of filler strip and spiral winding silk can be according to the actual construction situation of heat exchange tube and decide. This positioner is increase activity location on the basis is fixed a position to the traditional fixed of reduction, and the processing degree of difficulty, the
