Abstract
The present invention provides a kind of augmentation of heat transfer smoke pipe for Verticle gas hot-water boiler, it is characterised in that smoke pipe overcoat longitudinal ripple fin, the blind pipe of built-in band flight.Longitudinal ripple fin is welded according to the folding rear curling of the width of smoke pipe spacing half by sheet metal, overall corrugated fin uses high-frequency welding to be closely sleeved on smoke pipe outside wall surface, can significantly extend heat exchange area outside smoke pipe, thus strengthen the heat transfer free convection of cigarette outside tube water.After being wound around welding flight outside blind pipe, overall insertion smoke pipe is interior and fixes, and blind pipe makes the circulation area of flue gas reduce, and increases flue gas flow rate, and flight makes flue gas produce helical flow, extends flue gas flow, and then strengthens the heat convection of flue gas and smoke pipe wall.Novel reinforced flue structure is simple, easily manufactured, it is possible to the heat convection between strengthening flue gas and water, reduces the exhaust gas temperature of boiler, is effectively improved the thermal efficiency of boiler.
Description
Technical field
The present invention relates to the smoke pipe of a kind of Verticle gas hot-water boiler, particularly relate to a kind of bilateral augmentation of heat transfer smoke pipe.
Background technology
Verticle gas hot-water boiler is for fuel to produce the important thermal hardware of hot water with natural gas, and flue gas is walked in pipe,
Belonging to smaller hard flour pancake boiler, it is simple and compact for structure, floor space is little, environmental pollution is low, thus is widely used.Smoke pipe is pot
The core component of stove heat-exchange system, the most typically use smooth straight, and the body of heater limitation in height length of smoke pipe so that flue gas
Flow process is shorter, and the heat exchange area of smoke pipe is not enough, and flue gas is typically small with the convection transfer rate in tube wall face, thus smooth straight without
Method fully absorbs the heat of fuel combustion release, causes exhaust gas temperature higher, and its exhaust gas temperature is typically at 230 DEG C according to statistics
Above, not only wasting a large amount of heat energy, and can cause environmental thermal pollution, the thermal efficiency causing Verticle gas hot-water boiler is on the low side.
Meanwhile, the smoke pipe of Verticle gas hot-water boiler is outside is Static Water, after being heated by smoke pipe wall, and water generation free convection, because of
And its coefficient of heat transfer is smaller.Visible, if the overall thermal efficiency of boiler to be improved, the heat convection system of smoke pipe inner side and outer side
Number is required for improving.
Summary of the invention
Present invention aim to address above-mentioned technical problem, it is provided that a kind of novel structure, heat transfer efficiency are higher, manufacturing process
Simply, the bilateral augmentation of heat transfer smoke pipe of Verticle gas hot-water boiler it is suitable for.
The present invention adopts the following technical scheme that the bilateral augmentation of heat transfer smoke pipe of a kind of Verticle gas hot-water boiler, including indulging
To corrugated fin, flight, blind pipe and smoke pipe, it is characterised in that longitudinal ripple fin is closely sleeved on smoke pipe outside wall surface, blind pipe
Outer welding flight, blind pipe and the flight entirety of being wound around is inserted in smoke pipe；Longitudinal ripple fin by sheet metal according to smoke pipe spacing
The folding rear curling of width of half forms, and longitudinal ripple fin uses high-frequency welding to be closely sleeved on smoke pipe outside wall surface, makes
Outside smoke pipe, heat exchange area significantly extends, and smoke pipe and longitudinal ripple fin are all vertically layout；Blind pipe two ends welding block or
Only gas approach end welding blocks, and after blind pipe and flight entirety insert smoke pipe, occupies the central area circulation area of smoke pipe,
The circulation area making flue gas reduces, and flue gas flow rate improves, and then strengthens the convection heat transfer' heat-transfer by convection of flue gas and smoke pipe wall.
Described flight be wound around be welded on blind pipe outside wall surface, the helical angle of flight according to flue gas flow design time adjustable
Whole, after blind pipe and flight entirety insert smoke pipe, smoke pipe inwall is close in the outer of flight, makes flue gas produce helical flow, prolongs
Long flue gas flow, and then strengthen the heat convection of flue gas and smoke pipe wall.
After the present invention uses technique scheme, compared with prior art have the advantages that one is longitudinal ripple
Shape fin can significantly extend the heat exchange area outside smoke pipe, necessarily can strengthen the outer diabatic process of smoke pipe；Two is smoke pipe and longitudinal wave
Corrugated fin is all vertically layout, the free convection of outside tube water will not be produced form drag；Three is that blind pipe and flight entirety are inserted
After entering smoke pipe, occupy the part circulation area of smoke pipe, make the circulation area of flue gas reduce, it is possible to increase flue gas flow rate, Jin Erqiang
Change the convection heat transfer' heat-transfer by convection of flue gas and smoke pipe wall；Four is that smoke pipe inner screwy fin can make flue gas produce helical flow, extends flue gas flow,
And then strengthen the heat convection of flue gas and smoke pipe wall；Five be by smoke pipe outside structure-reinforced, smoke pipe can be significantly improved
Overall convection transfer rate, effectively strengthening flue gas and water convection heat transfer' heat-transfer by convection, exhaust gas temperature can be reduced, thus improve
Boiler thermal output, reaches to save the target of the energy.

Detailed description of the invention
Further illustrate embodiments of the present invention below in conjunction with the accompanying drawings.A kind of bilateral strengthening of Verticle gas hot-water boiler
Heat transfer smoke pipe, including longitudinal ripple fin, flight, blind pipe and smoke pipe, longitudinal ripple fin is sleeved on smoke pipe outside wall surface, spiral
Sheet is wrapped in blind pipe outside wall surface, then overall insertion smoke pipe, and blind pipe is isometric with smoke pipe.
Longitudinal ripple fin is welded according to the folding rear curling of the width of smoke pipe spacing half by sheet metal, overall
Longitudinal ripple fin uses high-frequency welding to be closely sleeved on smoke pipe outside wall surface, can significantly increase heat exchange area outside smoke pipe, smoke pipe
And longitudinal ripple fin is all vertically layout, the free convection of cigarette outside tube water will not be produced form drag.
Flight is wound around and is welded on blind pipe outside wall surface, and after blind pipe and flight entirety insert smoke pipe, the outer of flight is tight
Patch smoke pipe inwall, makes flue gas produce helical flow, extends flue gas flow, and then strengthens the heat convection of flue gas and smoke pipe wall.
The two ends welding of blind pipe blocks or only gas approach end welding blocks, and blind pipe and flight entirety insert smoke pipe
After, occupy the central area circulation area of smoke pipe, make the circulation area of flue gas reduce, it is possible to increase flue gas flow rate, and then strengthening
Flue gas and the convection heat transfer' heat-transfer by convection of smoke pipe wall.
Smoke pipe and be sleeved on longitudinal ripple fin, blind pipe and the flight of its outside wall surface and collectively form a kind of bilateral strengthening and pass
Hot smoke pipe.The simple in construction of this strengthening smoke pipe, easily manufactured, it is possible to the heat convection between strengthening flue gas and water, significantly drop
The exhaust gas temperature of low boiler, is effectively improved the thermal efficiency of boiler.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
