Abstract
The utility model relates to a heat transfer component used in the heat exchange system in the petroleum, the chemical and the power generation industries, in particular to an air-cooled condensing steam device used fin tube. The utility model solves problems of a larger thermal resistance and a low heat transfer efficiency in prior art in which the fin on the fin tube is arranged perpendicular to the center line. The air-cooled condensing steam device used fin tube comprises a flat special-shaped tube and a fin brazed out of the tube body. The fin is arranged inclined to the center line of the flat special-shaped tube and the inclination angle Beta=30-70 DEG. Compared with prior art, the utility model has the advantages of a large contact area between the fin and the pipe body, a smaller thermal resistance and a high heat transfer efficiency as the fin is arranged in an inclination way rather than a perpendicular way.
Description
Technical field
The utility model relates to a kind of oil, chemical industry, the heat transfer element of power industry in the heat-exchange system, particularly a kind of air cooling tubes condenser finned tube.
Background technology
Finned tube has been widely used in various types of heat-exchange apparatus and the firing equipment, and in order to improve its heat transfer property, way commonly used is the heat transfer area that increases finned tube, strengthen conduit, reduce the thermal contact resistance of fin and parent tube.The existing heat transfer used finned tube, and fin all is vertical setting with the centerline average of pipe, as Chinese patent ZL97250117.7, and the finned tube of mentioning among the ZL97236899.X, fin and body contact area are little like this, and thermal resistance is bigger, and heat transfer efficiency is low.
Summary of the invention
Fin is provided with its center line is vertical the utility model on the finned tube in order to solve in the prior art, and the problem that thermal resistance is big, heat transfer efficiency is low provides a kind of novel air cooling tubes condenser finned tube.
The utility model adopts following technical scheme to realize: the air cooling tubes condenser finned tube, comprise flat special pipe, and body is brazing fin outward, and the center line of fin and flat special pipe is obliquely installed, angle of inclination beta=30～70 °.
The utility model has following beneficial effect compared to existing technology: the vertically disposed relatively fin of the fin that is obliquely installed, big with the body contact area, thermal resistance is less, the heat transfer efficiency height.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is that the A of Fig. 1 is to view
Among the figure: the flat special pipe of 1-, 2-fin.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further, embodiment is used for illustrating of the present utility model, rather than it is imposed any restrictions.
The air cooling tubes condenser finned tube comprises flat special pipe 1, the flat special pipe 1 compound flat special pipe of steel aluminium commonly used, and the outer brazed aluminum corrugated fin 2 of body, fin 2 is obliquely installed with the center line of flat special pipe 1, angle of inclination beta=30～70 °.
