Abstract
The utility model discloses an internal and external spiral fin heat transfer tube, which mainly comprises at least a spiral heat transfer tube, and a spiral fin is pressed at the periphery of the spiral heat transfer tube. The inner side and the outer side of the body of each spiral heat transfer tube are both in a spiral shape. Two or more spiral heat transfer tubes are wound and connected with each other to form a spiral combined tube body. The internal and external spiral fin heat transfer tube also comprises at least an internal and external spiral heat transfer tube A or straight tube, and the spiral heat transfer tube is wound on the internal and external spiral heat transfer tube A or straight tube. The periphery of the spiral heat transfer tube or straight tube is provided with heat transfer auxiliary material. The utility model greatly reinforces the disturbance to fluid, the internal spiral reinforces heat transfer, and the outer spiral increases the heat dissipation area. The heat transfer capacity is greatly improved, the characteristics of bad heat transfer and unsmooth fluid of the prior art due to the corrosion at the adjacent part of an internal spiral fin guide vane and the heat transfer tube and the formation of honeycomb of the internal spiral fin on the fluid are completely eliminated, and the heat transfer tube has the advantages of high strength, long service life, compact and simple overall structure and convenient production.
Description
Technical field
The utility model relates to the fittings equipment on the heat transmission equipment, relates in particular to a kind of internal and external screw fin heat transfer pipe.
Background technology
Finned tube is the critical component of air type heat exchanger in order to conduct heat.The quality of finned tube radiating effect directly influences the radiating effect of radiator.The layout of the material of finned tube, the shape of fin, fin is that finned tube outer coefficient of heat transfer and radiating efficiency are had direct influence.On the other hand, the shape of finned tube also can influence its radiating efficiency.At present, on the basis of the finned tube that is produced on existing all size of finned tube, employing spiral fluted mode increases the area of dissipation in the pipe in parent tube, though improved radiating efficiency to a certain extent, but exist the gap that finned tube is corroded at adjacent, cause intensity and service life all to be affected with inner spiral fin stator and heat-transfer pipe.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of simple in structure, easy to make, internal and external screw fin heat transfer pipe that heat-transfer capability is high is provided.
For achieving the above object, the technical scheme that is adopted is: a kind of internal and external screw fin heat transfer pipe, mainly constitute, and described spiral heat-transfer pipe periphery is suppressed with helical fin equal shape in the shape of a spiral inside and outside the described every spiral heat-transfer pipe body by at least one spiral heat-transfer pipe.
The curl that is intertwined and connected mutually between the described spiral heat-transfer pipe more than two or two combination body.
Also comprise at least one internal and external screw heat-transfer pipe A, described spiral heat-transfer pipe is wrapped on this internal and external screw heat-transfer pipe A.
Also comprise at least one straight tube, described spiral heat-transfer pipe is wrapped on this straight tube.
Described spiral heat-transfer pipe periphery is provided with the heat transfer auxiliary material.
The beneficial effects of the utility model are: the utility model connects as one finned tube or the heat transfer auxiliary material that the spiral heat-transfer pipe is arranged on it on helix tube, has not only strengthened the disturbance of convection cell greatly, and inside spin has been strengthened heat transfer, and external spiral has increased area of dissipation.Heat-transfer capability is improved greatly, and thoroughly eliminated corrosion that prior art exists because of inner spiral fin stator and heat-transfer pipe adjacent and inner spiral fin convection cell and formed cellular bad and the fluid not smooth characteristics of conducting heat that produce, and intensity height, long service life, compact overall structure, simple, easy to make.
