Abstract
The invention discloses a high-performance irregular toothed spiral finned tube which comprises a base tube and fins arranged on the outer surface of the base tube. A plurality of notches are formed in the fins, and grooves are formed in the edges of the notches. The high-performance irregular toothed spiral finned tube has the advantages that the contact area between the side faces of the fins and smoke is increased, accordingly heat exchange is enhanced, and a heat exchange device can achieve the purposes of saving space and cost. Due to the fact that the fins have a certain thickness themselves, turbulent flow produced by the fins and the smoke can be strengthened, and accordingly the purposes of improving the heat exchange efficiency and strengthening the heat transfer effect are achieved. Irregular teeth are machined through a specially-manufactured cutter, so that the high-performance irregular toothed spiral finned tube has the advantages of being few in machining process modification, high in machining efficiency and the like and can meet the large-scale and industrial application requirements.
Description
Technical field
The invention belongs to industrial exhaust heat utilization, energy-conserving and emission-cutting technology field, particularly a kind of high-performance abnormity tooth punching spiral finned tube.
Background technology
Day by day in short supply along with energy resources, how reasonable energy utilization, the energy consumption reducing unit output value has become each production field particularly required urgent problem solved of high energy consumption department.Show according to interrelated data: AND ENERGY RESOURCES CONSUMPTION IN CHINA accounts for 21.5% of global total amount, but only create the GDP in the whole world about 12.3%.Trace it to its cause, be that the high energy consumption industry accounting in Industry Structure is high on the one hand; Be that the using energy source level of Industry Branch is low, the larger gap of existence compared with international most advanced level on the other hand.According to statistics, China has the industrial energy consumption close to 50% not to be utilized, but waste heat in a variety of manners directly emits, and the average recovery utilization rate of China's residual heat resources lags behind nearly 20 percentage points of international most advanced level.
Extended surface tube, as a kind of enhanced heat transfer component of high-efficiency compact, has the status of particular importance in UTILIZATION OF VESIDUAL HEAT IN, all has application in the smoke discharging residual heats such as station boiler, Industrial Boiler, Industrial Stoves.Extended surface tube is by fin is welded on light pipe surface, increases heat exchange area, hoisting power, thus reaches the object of augmentation of heat transfer.At present, industrial conventional extended surface tube has circular extended surface tube, screw type extended surface tube, H type extended surface tube etc.
If be fully used in industrial exhaust heat, improved the heat exchange property of extended surface tube by the improvement of new technology, so just effectively can reduce the heat exchange area of residual heat using device, thus reach and reduce costs, increase the objects such as utilization rate of waste heat.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of high-performance abnormity tooth punching spiral finned tube, by changing the shape of fin tooth punching, reaches objects such as increasing flow disturbance, the raising coefficient of heat transfer, lifting Unit Weight fin heat exchange area.
For solving the problems of the technologies described above, high-performance abnormity tooth punching spiral finned tube provided by the invention, comprise base tube and be arranged on the fin of described base tube outer surface, described fin is provided with several notches, and the trough rim of described notch is provided with groove.Set up notch and groove, object is the increase in the contact area of fin side and flue gas, and strengthens turbulence intensity when flue gas flows through fin, thus strengthens heat exchange, heat transmission equipment is reached and saves space and cost-effective target.
As preferably, the shape of described groove is waveform.
As preferably, described groove is provided with multiple breach.
As preferably, described breach be semicircle, triangle, rectangle, trapezoidal in one.
As preferably, described fin is spiral fin.
After adopting above structure, high-performance abnormity tooth punching spiral finned tube of the present invention compared with prior art, have the following advantages: because fin itself has certain thickness, abnormity tooth punching spiral finned tube adds the contact area of fin side and flue gas, thus enhancing heat exchange, heat transmission equipment is reached and saves space and cost-effective target; The notch that special-shaped tooth punching helix fin is opened simultaneously can strengthen the flow-disturbing of fin and flue gas, thus reaches the target improving heat exchange efficiency, augmentation of heat transfer effect; Process special-shaped tooth punching by special cutter, have that processing technology is changed less, working (machining) efficiency advantages of higher, the requirement of the scale of high-performance abnormity tooth punching extended surface tube, industrial applications can be met.

Detailed description of the invention
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, the high-performance abnormity tooth punching spiral finned tube that the present embodiment provides, comprise base tube 1 and be arranged on the fin 2 of described base tube 1 outer surface, described fin 2 is provided with several notches 3, the trough rim of described notch 3 is provided with groove, and described fin 2 is spiral fin.
As shown in Figure 2, the shape of described groove is waveform.
Described groove is provided with multiple breach 4, described breach be semicircle, triangle, rectangle, trapezoidal in one.As shown in Figure 3, the shape of described breach is trapezoidal.
The high-performance abnormity tooth punching spiral finned tube that the present embodiment provides, special tool is utilized to have certain thickness band steel steel band and process the tooth punching of difformity and angle, by ratio-frequency welding technique, special-shaped tooth punching fin is uprightly wound on the surface of base tube again, and adjacent special-shaped tooth punching fin pitch is met design requirement.This special-shaped tooth punching adds the heat exchange area of fin, enhances the flow-disturbing of fin and flue gas, enhances heat transfer effect.Compared with traditional tooth punching fin, special-shaped tooth punching fin can increase the heat exchange area about 5% of fin.Therefore the heat transfer space adopting high-performance abnormity tooth punching extended surface tube to reach to save waste heat equipment, reduce costs, improve the objects such as energy utilization rate.
