Abstract
The utility model discloses a kind of electric heater, its technical problem that metope can be avoided to absorb heat, to improve heat utilization efficiency.Comprise electrothermal tube, electrothermal tube is fixed with some fins, and fin is arranged in order along electrothermal tube, and fin contacts with electrothermal tube, and every a slice fin is positioned on relative two ends and is equipped with bending part, and bending part is towards same direction.This utilizes aluminium heat conduction physical characteristic rapidly, by outwards convection current and the radiation efficiently of the heat energy after conversion.This design is 2-3 times of X-type radiator area, solves the problem that press type fin heat transfer efficiency is low, and the problem of metope heat absorption when electric heater air-flow upwards circulates.By utilizing aerodynamic principle to make heating installation from the bottom to top after heating, free convection, heat conduction, a difficult problem for electric heating high energy consumption has been captured in this design.
Description
Technical field
The utility model belongs to the technical field of the electric calorifie installation of air heat, specifically relates to a kind of electric heater.
Background technology
Electric heater also claims electric heater, and it outwardly provides heat after converting electric energy to heat energy.Electric heater in the market comprises electrothermal tube, multi-disc fin and shell.Electrothermal tube and fin are installed in shell, and fin arranges equally spacedly and is installed on electrothermal tube.
At present, the fin electric heater adopted both at home and abroad is that the mode adopting steel pipe to add steel disc carries out heat transfer, and the thermal conductance efficiency of Steel material is compared with low and thermal conductive contact face is little, and waste energy consumption, the electrothermal tube life-span is short.Moreover fin in the form of sheets, lacks the guiding to air-flow, in use make a part of air-flow spread to metope, force metope to absorb heat, cause the thermal conductance efficiency of electric heater low.
Summary of the invention
The purpose of this utility model is to provide a kind of electric heater, its technical problem that metope can be avoided to absorb heat, to improve heat utilization efficiency.
The purpose of this utility model is achieved in that a kind of electric heater, comprise electrothermal tube, electrothermal tube is fixed with some fins, fin is arranged in order along electrothermal tube, fin contacts with electrothermal tube, every a slice fin is positioned on relative two ends and is equipped with bending part, and bending part is towards same direction.
As the preferred version of such scheme on the basis of such scheme: described fin is made up of pure aluminum material.
As the preferred version of such scheme on the basis of such scheme: electrothermal tube takes the shape of the letter U.
As the preferred version of such scheme on the basis of such scheme: the pipe of described electrothermal tube is made up of pure aluminum material.
The utility model gives prominence to compared to existing technology and useful technique effect is:
Electric heater of the present utility model have employed fin fin, makes fin have the effect of guiding to air-flow, avoids the problem of being absorbed heat by metope to metope diffusion when air-flow upwards circulates, thus improves the heat utilization efficiency of electric heater.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial structurtes schematic diagram of the present utility model.
Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-Fig. 2;
A kind of electric heater, comprises electrothermal tube 1 and some fins 2.Wherein, electrothermal tube 1 is for converting electrical energy into heat energy.Be filled with magnesia powder in the pipe of electrothermal tube, electrothermal tube electric conversion rate reaches more than 99.9%, and service life can reach more than 30 years.Preferably, as shown in fig. 1, electrothermal tube 1 takes the shape of the letter U.Electrothermal tube 1 is fixed with some fins 2, and fin 2 is arranged in order along electrothermal tube 1, and fin 2 contacts with electrothermal tube 1.In the present embodiment, fin 2 has guiding gutter 3, i.e. fin fin.See Fig. 2, every a slice fin 2 is positioned on relative two ends and is equipped with bending part 31, bending part, towards same direction, forms guiding gutter 3 whereby on fin.This electric heater have employed the fin of said structure, fin is made to have the effect of guiding to air-flow, by utilizing aerodynamic principle to make heating installation from the bottom to top after heating, free convection, heat conduction, avoid the problem of being absorbed heat by metope to metope diffusion when air-flow upwards circulates, improve heat utilization efficiency.
In the present embodiment, described fin 2 is made up of pure aluminum material.The pipe 11 of the electrothermal tube of described electrothermal tube 1 is made up of pure aluminum material.Owing to adopting pure aluminum material to make, improve thermal conductance efficiency.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
