Abstract
The utility model belongs to the technical field of the finned tube. The outwall of the main pipe (1) of the preferred whole steel matrix finned tube is a fin (2) which is made of the spiral groove, and the whole finned tube structure is thus formed. The design of the utility model is reasonable, because of the one forming design (from the parison tube into the product directly) and no thermal contact resistance, the finned tube can be used in the situation of high temperature and bad environment without loosening of the fin. The rib surface is level and smooth, which eliminates the phenomenon of gathering ash, ash blocked, welding-off, and rupture and so on, because of the rib folding and the convex and concave of the spatial thermal resistance between the two bodies. The efficiency of the heat transfer is improved, and the service life is longer. The utility model has the advantages of small size, lightweight, big heat exchange surface, so the heat transfer coefficient is high, the heat exchange project cannot be influenced by the temperature change. The great problem of the circulating fluid-bed transformation for high speed of wind, big pulverized coal particle and severe wear can be solved.
Description
Affiliated technical field
The utility model belongs to the finned tube technical field, mainly proposes a kind of monolithic devices base steel finned tube.
Background technology
As everyone knows, in various cold and hot (element) switch, for augmentation of heat transfer, taked the various multi-form heat exchange areas that enlarge, reduced volume is to reach the purpose of practicality.Finned tube is as a vitals in the heat-exchange device, and the expansion of its heat exchange area is directly connected to heat transfer efficiency.Traditional finned tube has not adapted to era development and has been eliminated owing to limit by background condition.Though and modes such as the sheet string type that extensively adopts at present, wound form and embedding welding have enlarged heat exchange area, but because the resistance of the air of combination can't be eliminated between disome, in operating mode because of the infiltration of the thermal coefficient of expansion difference accelerating space gas of disome, cause break, sealing-off and be subjected to serious corrosion, thereby influenced heat transfer efficiency and service life, even caused adverse consequences such as complete switch inefficacy hot in nature.Simultaneously, formed folding and concavo-convex meeting produces serious knot ash, clogging phenomenon to finned tube on winding process middle rib surface, and overall thermal switch heat transfer efficiency is obviously descended.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of monolithic devices base steel finned tube.Not only volume is little, in light weight, heat exchange area is big, heat transfer coefficient is high for this finned tube, and wear-resistant, thermal resistance is little.
The utility model realizes that the technical scheme that above-mentioned purpose adopts is: the outer wall of female pipe is the fin that helical groove constitutes, and forms the integral fins tubular construction.
The utility model is reasonable in design, because it is integrated (transitting directly to finished product by the base pipe), does not have thermal contact resistance, thus this finned tube can be applied to temperature higher, the occasion that environment for use is comparatively abominable and the fin relaxation can not take place.The rib surfacing is smooth, the existence of phenomenon such as thoroughly eliminated the knot ash that the space thermal resistance is folding because of the rib table and concave and convex phenomenon is caused, stifled ash, sealing-off between disome, break.Heat transfer efficiency and service life have been improved.Because its volume is little, in light weight, heat exchange area is big, thereby the heat transfer coefficient height, is not acted upon by temperature changes in the heat exchange engineering, solved the circulating fluid-bed transformation because of wind speed height, big, this great difficult problem of serious wear of pulverized coal particle.
Description of drawings
The utility model accompanying drawing is a structural representation.
Among the figure, 1, female pipe, 2, fin.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in drawings, present embodiment is to be female pipe 1 with the seamless metal pipe, and metal tube can be a steel pipe, also can be copper pipe etc.The outer wall of female pipe 1 is fin 2 structures that uniform helical groove constitutes, and forms the integral fins tubular construction thus.This metal tube becomes the one-piece auger finned tube through hot rolling.It is T-shape, straight type or " R " transiens that the shape of fin can be.
Claims (2)
1, a kind of monolithic devices base steel finned tube is characterized in that: the outer wall of female pipe (1) is the fin (2) that helical groove constitutes, and forms the integral fins tubular construction.
2, monolithic devices base steel finned tube according to claim 1 is characterized in that: the shape of fin (2) can be T-shape, straight type or " R " transiens.
