Abstract
The invention relates to a heat exchange tube with internal and external fins. The heat exchange tube comprises a tube body, wherein a plurality of external fins are formed on the outer wall of the tube body; a plurality of internal fins are formed on the inner wall of the tube body; the inner wall is lined with a polytetrafluoroethylene coating; the internal and external fins are formed at one time in a spinning manner; each external fin is arranged in the circumferential direction of the tube body; the external fins are uniformly arranged along the length direction of the tube body; each internal fin is Z-shaped; the distance between every two adjacent internal fins is longer than that between every two adjacent external fins. The heat exchange tube has the advantages of high thermal conductivity, high material consistency, high corrosion resistance and low cost.
Description
Technical field
The present invention relates to a kind of inside and outside fin heat exchanger tube, belong to field of heat exchange.
Background technology
The heat exchange fin in market is arranged on the outside of body usually, and its drawback existed is that heat exchange efficiency is low, and corrosion resistance is poor, and production process is complicated.
Summary of the invention
For overcoming the defect of prior art, the invention provides a kind of inside and outside fin heat exchanger tube, technical scheme of the present invention is: a kind of inside and outside fin heat exchanger tube, comprise body, outer fin is formed at the outer wall of body, inwall forms inner fin, and inwall is lined with polytetrafluorethylecoatings coatings, and described inner fin and outer fin pass through the mode one-shot forming of spinning.
Each outer fin is arranged on body circumferentially, and several outer fin is evenly arranged along the length direction of body; Described inner fin is several, and each inner fin is all in Z-shaped setting, and the spacing between adjacent two inner fins is greater than the spacing between adjacent two outer fins.
Advantage of the present invention is: heat conductivity is good, and material uniformity is strong, and rotproofness is good, and cost is low.
Accompanying drawing explanation
Fig. 1 is agent structure sectional view of the present invention.
Detailed description of the invention
Further describe the present invention below in conjunction with specific embodiment, advantage and disadvantage of the present invention will be more clear along with description.But these embodiments are only exemplary, do not form any restriction to scope of the present invention.It will be understood by those skilled in the art that and can modify to the details of technical solution of the present invention and form or replace down without departing from the spirit and scope of the present invention, but these amendments and replacement all fall within the scope of protection of the present invention.
See Fig. 1, a kind of inside and outside fin heat exchanger tube, comprises body 2, forms outer fin 3 at the outer wall of body 2, and inwall forms inner fin 1, and inwall is lined with polytetrafluorethylecoatings coatings, and described inner fin 1 and outer fin 3 pass through the mode one-shot forming of spinning.
Each outer fin 3 is arranged on body 2 circumferentially, and several outer fin 3 is evenly arranged along the length direction of body 1; Described inner fin 1 is several, and each inner fin 1 is all in Z-shaped setting, and the spacing between adjacent two inner fins 1 is greater than the spacing between adjacent two outer fins 3.，
The effect of outer fin 3 increases outer heat exchange area, in endothermic process, fin is to the turbulence promoting fluid, enhanced fin heat transfer, windage is little, destroy thermal boundary layer and fully absorb thermal source, inner fin 1 effect makes current by not stopping inside rotating percussion heat exchanger tube during heat exchanger tube, make water turbulence, the noise problem that during forced heat-exchanging reduction heat exchange, the heat transfer of high-temperature region is uneven, reduce heat exchange inequality and produce incrustation scale problem, improve heat exchange efficiency, reduce heat exchange volume, inside and outside fin on finned tube is integrated by the dynamic spinning of heavy wall aluminum pipe, heat conductivity is good, material uniformity is strong, rotproofness is good, cost is low.
Claims (1)
1. an inside and outside fin heat exchanger tube, comprises body, it is characterized in that, forms outer fin at the outer wall of body, and inwall forms inner fin, and inwall is lined with polytetrafluorethylecoatings coatings, and described inner fin and outer fin pass through the mode one-shot forming of spinning; Each outer fin is arranged on body circumferentially, and several outer fin is evenly arranged along the length direction of body; Described inner fin is several, and each inner fin is all in Z-shaped setting, and the spacing between adjacent two inner fins is greater than the spacing between adjacent two outer fins.
