Abstract
The utility model discloses an electric heater, it can improve thermal conductance efficiency. Including the electrothermal tube, the cover is equipped with the fin pipe on the electrothermal tube, and the fin pipe is formed by the aluminum pipe suppression, and the fin pipe has pipe and a plurality of fins, pipe and electrothermal tube tight fit. This utilizes the physical characteristic that aluminium heat conduction is rapid, outside convection current of heat energy efficient and radiation after will changing. The problem of suppression type fin thermal energy contact clearance leakage, heat transfer efficiency is low is solved. Through utilizing the aerodynamic principle to make heating installation supreme by down, natural convection conducts the heat, has captured the difficult problem of electric heating high energy consumption after generating heat. Electrothermal tube electric heat transformation rate reaches more than 99.9%, and life can reach more than 30 years.
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, compared with low and thermal conductive contact face is little, wastes energy consumption.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 electric heater heat utilization efficiency low.Press type fin thermal expansion contact is not tight, reduces thermal conductance efficiency yet.In addition, electrothermal tube is low for useful life.
Summary of the invention
The purpose of this utility model is to provide a kind of electric heater, and it can improve thermal conductance efficiency.
The purpose of this utility model is achieved in that a kind of electric heater, comprises electrothermal tube, and electrothermal tube is arranged with finned round tube, and finned round tube is suppressed by aluminum pipe and formed, and finned round tube has pipe and some fins, pipe and electrothermal tube tight fit.
On the basis of such scheme and as the preferred version of such scheme: be positioned on relative two ends and be equipped with bending part on every a slice fin, bending part is towards same direction.
On the basis of such scheme and as the preferred version of such scheme: described electrothermal tube comprises pipe and magnesia powder, and magnesia powder is filled in pipe.
On the basis of such scheme and as the preferred version of such scheme: described pipe 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, because electrothermal tube and pipe are friction tight, makes to have high thermal conductance efficiency between electrothermal tube and pipe, moreover, because fin and pipe are integrative-structures, further increase thermal conductance efficiency, solve a difficult problem for the high energy consumption existed in prior art.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of finned round tube of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-Fig. 2;
This gives a kind of electric heater, comprise electrothermal tube 1 and finned round tube 2.In the present embodiment, described electrothermal tube comprises pipe, high temperature nickel filament (heater strip) and magnesia powder, and magnesia powder is filled in pipe.Preferably, described pipe is made up of pure aluminum material.
Electrothermal tube 1 is arranged with finned round tube 2, and finned round tube is suppressed by aluminum pipe and is formed.As shown in Figure 2, finned round tube 2 has some fins 21 and pipe 22, and that is, fin and pipe are integrated.Pipe and electrothermal tube tight fit.Because pipe and electrothermal tube are close contacts, improve thermal conductance efficiency.
As shown in Figure 2, every a slice fin 21 is positioned on relative two ends and is equipped with bending part 23, and bending part 23 is towards same direction.Guiding gutter 24 is formed whereby on fin 21.By this structure, after electric heater heating, by utilizing aerodynamic principle to make heating installation from the bottom to top, free convection, heat conduction, in the process, fin has the effect of guiding to air-flow, improves heat utilization efficiency, captures a difficult problem for high energy consumption whereby.
The manufacturing process of the electric heater of the present embodiment is: the first step is: the pipe of aluminum pipe as heat-generating pipe adopting diameter 12mm, installs high temperature nickel filament, then install high-temperature oxydation magnesium powder additional in the middle of pipe, rear wiring sealing.This design electrothermal tube electric conversion rate reaches more than 99.9%, and useful life can reach more than 30 years.Second step is: the electrothermal tube making diameter 9.9mm after 12 grades of compactings.3rd step is: make heavy wall aluminum pipe, 1006 type aluminums are made overall diameter 30mm, wall thickness 10mm, the aluminum pipe of bore 10mm.4th step is: be arranged in aluminum pipe by electrothermal tube.5th step is: put on press device by heavy wall aluminum pipe and suppress, make it be closely as one.6th step is: carry out surface oxidation treatment again after having suppressed, and the height making round fin is 20.5mm, and the height of wing root 25 is the finned round tube of 1mm.7th step is: 90 degree of bendings are carried out in two faces of the symmetry of circle fin, and bending height 4mm, forms fin.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection range 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 range of the present utility model.
