Abstract

The utility model relates to a kind of high heat-exchange performance serpentine fin heat exchange pipe, it includes base tube and wave-fin;The base tube uses flat pipe, and the section of the base tube is in prolate type, and two sides of the base tube are plane, and wave-fin is respectively welded on two sides of the base tube, and the wave-fin uses ripple calking piece.The base tube of the utility model is cracked on wave-fin using flat pipe in flat pipe two sides plane-welding wave-fin, is conducive to eliminate lateral whirlpool, mixes fluid more abundant, to improve flowing and the heat exchange property of fin.

Description

High heat-exchange performance serpentine fin heat exchange pipe
Technical field
The utility model relates to gas heat exchanger technical field more particularly to a kind of high heat-exchange performance serpentine fin heat exchange pipes.
Background technique
Finned tube is the core and key element of gas heat exchanger (such as air cooling tubes condenser), its performance, which directly affects, changes The performance and application of hot device.On the air cooling tubes condenser of power station or coal chemical industry turbine low pressure cylinder steam discharge, it is often used wave-fin pipe (also known as single row of tubes) is used as heat exchange element.
The corrugated type of fin design of wave-fin pipe currently used in the market, without any aperture, seam etc., wave on fin Line type fin increases the disturbance of fluid, and heat transfer characteristic is strengthened, while also bringing biggish drag losses, and this The heat exchange efficiency room for promotion of kind finned tube specific energy consumption is limited.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of high heat-exchange performance serpentine fin heat exchange pipes can be into one Step improves the heat exchange efficiency of unit efficiency.
Purpose of the utility model is realized as follows:
A kind of high heat-exchange performance serpentine fin heat exchange pipe, it includes base tube and wave-fin;The base tube uses flat pipe, institute The section of base tube is stated in prolate type, two sides of the base tube are plane, are respectively welded on two sides of the base tube Wave-fin, each facade of the wave-fin use the shape of ripple calking piece, and the wave-fin surface is in ripple type And be equipped with it is several crack, it is described crack it is convex.
Compared with prior art, the utility model has the beneficial effects that
The base tube of the utility model uses flat pipe, in flat pipe two sides plane-welding wave-fin, on wave-fin It cracks, is conducive to eliminate lateral whirlpool, mix fluid more abundant, to improve flowing and the heat exchange property of fin.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of the utility model wave-fin.
Fig. 3 is the side view of the utility model wave-fin.
Wherein:
Base tube 1, wave-fin 2 crack 3.
Specific embodiment
Embodiment 1:
Referring to Fig. 1, the utility model relates to a kind of high heat-exchange performance serpentine fin heat exchange pipe, it includes base tube 1 and snakelike Fin 2.
The base tube 1 uses flat pipe, and the section of the base tube 1 is in prolate type, and two sides of the base tube 1 are flat Face, wave-fin 2 is respectively welded on two sides of the base tube 1, and each facade of the wave-fin 2 is all made of ripple punching The shape of patch, i.e., described 2 surface of wave-fin in ripple type and be equipped with it is several crack 3, it is described crack it is 3 convex.
Working principle:
The utility model uses flat pipe as base tube 1, in 1 two sides plane-welding wave-fin 2 of base tube, the snakelike wing Piece 2 uses ripple calking piece, to reach enhancing air side flow-disturbing effect and heat transfer effect purpose;It is changed using the utility model When hot, air manages outer flowing in base tube 1 and wave-fin 2, and the media such as steam are flowed in base tube 1 and carried out with pipe outside air Heat exchange.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it It is interior.
