Abstract
The utility model belongs to an electrical heating apparatus, and relates to a highly effective heat dissipating electrical heating tube which comprises a metal tube shell, electric-heat wires installed in the tube shell and heat conducting insulating filling, wherein striped radiating fins are spirally wound on the outer surface of the tube shell, and the unfolding shape of the section of the radiating fins on the length direction is straight. As the straight radiating fins are wound on the surface of the tube shell, an air current channel formed on the surface of the tube shell is led to be smoother, which can improve the passing speed of air current, thereby further improving heat dissipating efficiency, furthermore, as the straight radiating fins are wound on the tube shell, the longitudinal space occupied by each circle of the fins is comparatively small, thereby an electrical heating tube with certain length can be provided with more circles of fins, which further improves the heat dissipating efficiency.
Description
Technical field
The utility model belongs to electric heater unit, relates to a kind of high efficiency and heat radiation electric heating tube.
Background technology
The auxiliary electric heater unit that uses in the existing domestic air conditioner generally all is to adopt electric heating tube, and this mainly is because circular electric heating tube volume is less, electrothermal calefactive rate is very fast, characteristics such as easily manufactured.Yet because the exothermic material of electric heating tube is a nichrome, in case electric heating energising heating tube is just carried out work with the power of maximum, the surface of electrothermal tube can produce " rubescent " phenomenon because temperature is too high.When blower fan catastrophic failure occurring and under the situation of stop work, bringing a series of potential safety hazard for the use of household electrical appliance.For this reason usually all the electrothermal tube outer surface around on radiating fin, to increase the radiating rate of electric heating tube, reduce " rubescent " phenomenon of electrothermal tube.It is corrugated that radiating fin is generally, promptly the section expansion shape on the finned length direction is corrugated (as shown in Figure 3), though corrugated radiating fin itself has bigger area of dissipation, but because after corrugated radiating fin is wound on the electrothermal tube, hindered nearly half (tube-surface) draught area, reduced the speed of ventilating, thereby its radiating efficiency is not high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of radiating efficiency high high efficiency and heat radiation electric heating tube.
High efficiency and heat radiation electric heating tube of the present utility model comprises Can and is installed in shell interior heating wire and heat conductive insulating filler, spiral is wound with banded radiating fin on the shell outer surface, and the section expansion shape of radiating fin on its length direction be shape linearly.
The utility model is owing to the rectilinear radiating fin of coiling on the shell surface, and the gas channel that the shell surface is formed is more unobstructed, can improve the speed that air communication is crossed, and then improves radiating efficiency; In addition, the longitudinal space that each circle fin takies when being wound on the shell owing to rectilinear radiating fin is less, thereby the fin number of turns that can be provided with on the electrothermal tube of certain-length is more, and this has also further improved its radiating efficiency.
