Abstract
The utility model relates to a low voltage heater with an electrothermal film, and electrodes of the power supply which are distributed in a mutually staggered or encased form are installed in the electrothermal film on the surface of the substrate. The heater with an electrothermal film of the utility model can be used for boiling drinking water for a driver and persons on an automobile, using the low voltage of the motor or the battery of the automobile.
Description
The utility model relates to a kind of is the electric heater of exothermic material with the Electric radiant Heating Film, and particularly a kind of employing low-tension supply can obtain more powerful electrothermal film heater.
With the surface that pot, cup or other suitable matrix are sprayed or be applied to inorganic material such as some conducting polymer composite or metal oxide, pottery, as exothermic material, and the Electric radiant Heating Film mode of heating of the electrode form of setting therein and power supply UNICOM is used gradually.Disclose respectively as documents such as state's patent 89214522.6 and 92231698.8 and a kind ofly in the ring-type Electric radiant Heating Film, the Electric radiant Heating Film saucepan of introducing and drawing two power electrode forms to be set in the radial symmetric mode.Its electrode is short and small, and apart from each other, thereby only is suitable for the higher power supply of voltage such as civil power and uses down and could guarantee enough heats that adds, and can't use for the LVPS that is lower than 36 volts.Chinese patent 89207814.6 has been introduced a kind of Electric radiant Heating Film oil pan heater that is used for automobile, though can under the low-voltage of automobile storage battery, use, but the form of its power electrode is influenced by its spacing distance still and warm thermal source only can be provided, and can't provide for example to boil the more high-power like this heat that adds of boiling water.
The purpose of this utility model is to provide a kind of be suitable under the low-voltage condition to use and more powerful electrothermal film heater can be provided at the problems referred to above, for example can be particularly suited for but the electric heater that is not limited only to use on automobile.
The utility model is at these characteristics of low supply voltage, and the power electrode that is arranged on spray or be applied in the Electric radiant Heating Film of suitable matrix surface is taked to distribute by form interlaced or that hold.This distribution can have multitude of different ways.The power electrode of one or both sides can be designed to the multiple-limb shape, make it then each branch is interlaced and arrange; Also the power electrode of one or both sides can be designed to closure or open curve or polyline shaped, make it mutually to surround wholly or in part or the coiling mode is arranged then, for example annular form or helical form form for being nested with mutually.Power electrode takes the advantage of this arrangement mode just to be can be provided with according to the heating needs on the one hand the electric membranous layer of maximum area, simultaneously again can be according to the characteristics of low-voltage, make effective spacing of both sides power electrode relative in the electric membranous layer narrow down to the position that guarantees to have best heating efficiency as far as possible, promptly can the best caloric value of low-voltage acquisition on desirable Electric radiant Heating Film area.
Below structure of the present utility model is described with example shown in the drawings.But scope of the present utility model is not limited only to this example.
The electrothermal film heater of Fig. 1 mutually staggered electrode
Fig. 2 holds the electrothermal film heater of shape electrode mutually
As shown in Figure 1, be coated with the Electric radiant Heating Film 2 of conducting polymer composite on the surface of this routine matrix 1, its area shape and big I are determined by the matrix of need heating.The matrix 1 of this moment can be the bottom of heating containers such as nature of glass pot, cup directly, or is used for the universal calandria of other container of support.The both sides power electrode all is designed to the multiple-limb shape, and then is arranged in the Electric radiant Heating Film 2 in interlaced mode.The resistance of Electric radiant Heating Film is 0.48-1.92 Europe, and under 24 volts of voltage conditions, heating power can reach 250～300 watts.
In the electrothermal film heater shown in Figure 2, Electric radiant Heating Film 2 is circular, and its inner periphery edge and cylindrical periphery respectively are that power electrode 3, two electrodes of a side are and are nested with shape mutually and distribute.
Electrothermal film heater of the present utility model applicable to boiling drinking water with the LVPS of electric motor of automobile or storage battery, is drunk for the driver and the personnel of riding especially.
