Abstract
The utility model relates to a high frequency welded spiral fin tube provided with a bending position with fins. The utility model relates to the improvement of the structure of a high frequency welded spiral fin tube for a boiler. The high frequency welded spiral fin tube is used in a power station boiler at present. However, only the upper part of the outer surface of a straight tube position of a base tube of the high frequency welded spiral fin tube in the existing power station boiler is fixed with spiral fins, and the upper part of the outer surface of a bending position of the base tube is not fixed with spiral fins, which leads the integral heat radiation area of the high frequency welded spiral fin tube in the boiler not to reach the maximum value. The upper part of the outer surface of a straight tube position A of a base tube (1) of the utility model is fixed with straight tube spiral fins D; the upper part of the outer surface of a bending position B of the base tube (1) is fixed with bending tube spiral fins E. The utility model has the advantages that the upper part of the outer surface of the bending position of the base tube is fixed with the spiral fins, which improves the utilization rate of space in the boiler; compared with the original high frequency welded spiral fin tube, wherein, the bending position of the base tube of which is not provided with the spiral fins, the heat radiation area of the bending position of the utility model is enhanced by 4-5 times, and the production output of the boiler is improved.
Description
Technical field: the utility model relates to the improvement of boiler with the high frequency welding spiral fin tube structure.
Background technology: high frequency welding spiral fin tube now has been widely used in the station boiler, but the high frequency welding spiral fin tube in the existing station boiler, only on the outer surface at parent tube straight tube position, be fixed with helical fin, and fixing helical fin not on the outer surface of parent tube crooked position, make the area of dissipation of boiler medium-high frequency weldering spiral fin coil integral body not reach maximum, want to reach the certain evaporation capacity of boiler, can only increase the volume of boiler.
The utility model content: for solving the deficiency that prior art exists, the utility model provides a kind of crooked position finned high frequency welding spiral fin tube, and it should have the characteristics that improve the high frequency welding spiral fin tube area of dissipation.The utility model is made up of parent tube 1, helical fin 2; Parent tube 1 is divided into the naked pipe position C at straight tube position A, crooked position B and two ends, helical fin 2 is divided into straight tube helical fin D and bend pipe helical fin E, be fixed with straight tube helical fin D on the outer surface of the straight tube position A of parent tube 1, be fixed with bend pipe helical fin E on the outer surface of the crooked position B of parent tube 1.The arrangement of bend pipe helical fin E on parent tube 1 crooked position B outer surface, its pitch of bend pipe helical fin E that is positioned at center of circle far-end is greater than the pitch of straight tube helical fin D, and its pitch of bend pipe helical fin E that is positioned at center of circle near-end is less than the pitch of straight tube helical fin D.The utility model has the advantages that on the outer surface of parent tube crooked position and be fixed with helical fin, improved utilization of space in the boiler, with do not have helical fin to compare on original parent tube crooked position, the area of dissipation of its crooked position has increased by 4～5 times, has improved exerting oneself of boiler.
Description of drawings: Fig. 1 is an overall structure schematic diagram of the present utility model, Fig. 2 is that helical fin 2 is fixed on two the 90 ° structural representations on parent tube 1 outer surface that is provided with in opposite directions, Fig. 3 is that helical fin 2 is fixed on two the 130 ° structural representations on the parent tube that is oppositely arranged 1 outer surface, and Fig. 4 is that helical fin 2 is fixed on the structural representation on " bow " shape parent tube 1 outer surface.
The specific embodiment: present embodiment is made up of parent tube 1, helical fin 2; Parent tube 1 is divided into the naked pipe position C at straight tube position A, crooked position B and two ends, helical fin 2 is divided into straight tube helical fin D and bend pipe helical fin E, be fixed with straight tube helical fin D on the outer surface of the straight tube position A of parent tube 1, be fixed with bend pipe helical fin E on the outer surface of the crooked position B of parent tube 1.The arrangement of bend pipe helical fin E on parent tube 1 crooked position B outer surface, its pitch of bend pipe helical fin E that is positioned at center of circle far-end is greater than the pitch of straight tube helical fin D, and its pitch of bend pipe helical fin E that is positioned at center of circle near-end is less than the pitch of straight tube helical fin D.Angle＜180 ° of crooked position B that are used for fixing the parent tube 1 of bend pipe helical fin E.Helical fin 2 can be fixed on two 90 ° parent tube 1 outer surfaces that are provided with in opposite directions, helical fin 2 also can be fixed on two the 130 ° parent tube that is oppositely arranged 1 outer surfaces, helical fin 2 also can be fixed on parent tube 1 outer surface of " bow " shape, and bend pipe helical fin E can also be fixed on the outer surface of crooked position B of the irregular trend of multi-angle on the parent tube 1.As what be connected with other high frequency welding spiral fin tube or boiler body is the naked pipe position C of parent tube 1.
