Abstract
An aluminum fin structure of a heat-emitting device is provided. The aluminum fin structure of the heat-emitting device comprises parallelly-arranged electric heating tubes; the electric heating tubes are stringed with a plurality of aluminum fins in array distribution; the left end and right end of each aluminum fin bend towards the same side, so that the upper end surface and the lower end surface of the aluminum fin are groove-shaped; and preferably, the bending angles of the left end portion and the right end portion of the aluminum fin are 90-degree angles. With the bent aluminum fins adopted, more complete gas channels are formed between the aluminum fins, and therefore, turbulence flow phenomena can be reduced, and heat circulation speed of heat convection wind can be effectively improved, and heat exchange efficiency can be improved; and the strength of the aluminum fins are increased, and therefore, thermal bending deformation phenomena can be effectively reduced, and the service life of the heat-emitting device can be prolonged; the whole thickness of the heat-emitting device is reduced, and the overall size of the device can be decreased, and the device can be more beautiful.
Description
Technical field
The utility model relates to electro-heat equipment, relates in particular to a kind of aluminium fin structure of electro-heat equipment.
Background technology
At present, the general volume of heater traditional on market is larger, and goes here and there between aluminium flake while using and easily produce turbulent phenomenon, has the defect that heat exchanger effectiveness is not high.On the other hand, aluminium flake easily occurs bending and deformation because of heating, thereby causes the useful life of heater short.
Utility model content
For overcoming the problem of the deficiencies in the prior art and existence, the utility model provides a kind of aluminium fin structure of simple and reasonable electro-heat equipment, to reduce the volume of electro-heat equipment, improves heat exchanger effectiveness and useful life.
The utility model is achieved through the following technical solutions: a kind of aluminium fin structure of electro-heat equipment, comprise the electric heating tube be arrangeding in parallel, on described electric heating tube, string has some aluminium fins of array distribution, the left and right both ends of described aluminium fin, towards the same side to bending, make the upper/lower terminal face of this aluminium fin be grooved.
Preferably, the bending angle at the left and right both ends of described aluminium fin is all 90 °.
Preferably, described aluminium fin is formed by the bending of rectangle aluminium flake.
Preferably, described electric heating tube is two, also fixes respectively through the installing hole of the upper/lower terminal portion that is distributed in aluminium fin.
Further, described two electric heating tubes are at one end electrically connected by electric wire.
The utility model compared with the prior art, the aluminium fin bending by design, make the more complete gas passage of formation between aluminium fin, in the running of electro-heat equipment, in the time of hot air rising, reduce turbulent phenomenon, make hot-air rise to rapidly the top outlet inlet of electro-heat equipment, effectively improve the thermal cycle speed of thermal convection wind, made indoor temperature increase more quickly, improved heat exchanger effectiveness; And after the bending of aluminium fin, its strength increase, effectively reduces the phenomenon that heated bending is out of shape, more firm, extends the useful life of electro-heat equipment; On the other hand, after the bending of aluminium fin, make the size decreases of its Width, thereby can make the complete machine thickness attenuation of electro-heat equipment, dwindle the volume of complete machine, when reducing cost, more attractive in appearance.

Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be pointed out that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
The aluminium fin structure of a kind of electro-heat equipment as shown in accompanying drawing 1,2,3, comprise the electric heating tube 1 be arrangeding in parallel, on described electric heating tube, string has some aluminium fins 2 of array distribution, and the left and right both ends of described aluminium fin, towards the same side to bending, make the upper/lower terminal face of this aluminium fin be grooved.
In preferred embodiment of the present utility model, the bending angle at the left and right both ends of described aluminium fin 2 is all 90 °.Described aluminium fin 2 is formed by the bending of rectangle aluminium flake, is integrated trench structure, and rolling is easy to process.These some aluminium fins become equidistant array distribution in electric heating tube periphery.
As shown in accompanying drawing 4,5, existing aluminium fin is a rectangle laminated structure, does not form a passage complete, that direction is consistent between adjacent aluminium fin, and in the time that electro-heat equipment starts to heat, turbulent phenomenon easily occurs hot-air, reduces heat exchanger effectiveness.And after aluminium fin of the present utility model bending, form a comparatively complete air duct, and effectively reduce turbulent phenomenon, make hot-air rise to rapidly the top outlet inlet of electro-heat equipment, effectively improve the thermal cycle speed of thermal convection wind.
Compare with accompanying drawing 5 by accompanying drawing 2, make the size decreases of its Width after can finding out the bending of aluminium fin, thereby can make the complete machine thickness attenuation of electro-heat equipment; And the intensity of the strength ratio rectangle laminated structure of the aluminium fin of bending is larger, therefore reduces production costs, when improving outward appearance, improved the durability of aluminium fin, extends the useful life of electro-heat equipment.
Described one or more electric heating tube is together in series aluminium fin through aluminium fin successively, and electric heating tube connects power supply, and power supply is connected with a controller.In the present embodiment, described electric heating tube 1 is two, also fixes respectively through the installing hole of the upper/lower terminal portion that is distributed in aluminium fin.Described two electric heating tubes 1 are at one end electrically connected by electric wire 3.Preferably, described electric heating tube is made up of metallic aluminium or metallic copper.
The content of mentioning in above-described embodiment is not to restriction of the present utility model, is not departing under the prerequisite of inventive concept of the present utility model, and any apparent replacement is all within protection range of the present utility model.
