Abstract
This invention relates to an electric heater including a ceramic sleeving with sealed bottom, a ceramic core set in it, resistance wires winding outer wall of the said core and heat-conducting insulation powders between the core and said ceramic sleeving. Since resistance wires wind the outer wall of the core and powder of heat-conduction and insulation is filled between the sleevings, it can either transfer heat effectively or provent the resistance wire from corrosion or intrusion by acid, alkali, salt and alloys so as to prolong the life of electric-heaters, at the same time, since it is protected by ceramic sleeving, the heater can be inlet in the heated medium to realize internal heating and reduce dispersion of heat to increase efficiency and usability of electric energy.
Description
Technical field
The present invention relates to a kind of electric heater, particularly about a kind of electric heater that in the accumulation of heat power consumption equipment, uses.
Background technology
At present, China's electric utility has obtained significant progress, energy output has occupied the second place of the world with the installation total capacity, meanwhile, new problem has appearred in development of electric power industry and electricity needs variation: the one, and whole nation generating utilizes hourage to descend year by year, generating capacity fails to make full use of, and some new operation units is arranged even be in idle state; The 2nd, the peak load of electrical network increases very fast, and the network load rate reduces year by year.Huge electric power peak-valley difference and peak value growth rate must propose very high requirement to power peak regulation, and the safe operation of electrical network has been constituted certain threat.In order to alleviate the pressure of peak load of grid, various places have been developed various peak load stations in succession, as gas turbine power plant, hydroenergy storage station etc., but this does not fundamentally solve the contradiction that causes the electricity consumption peak-valley difference, and improving constantly along with economic development, living standards of the people, resident's household electricity sustainable growth will further strengthen the peak-valley difference of electrical network power load.Address this problem, have only and carry out the peak and valley time electricity price, and greatly develop the accumulation of heat power consumption equipment, make the cheap low ebb electricity of resident's more than enough usefulness of energy, electrical network is realized peak load shifting with this.
Yet heat storage medium mostly is salt, metal and metal alloy greatly in common accumulation of heat power consumption equipment, and these materials at high temperature corrosivity are extremely strong, can not directly electric heater be imbedded accumulation of heat.Therefore can develop a kind of have anticorrosive function and the high electric heater of the efficiency of heating surface, become the key point of restriction accumulation of heat power consumption equipment development.
Summary of the invention
At the problems referred to above, purpose of the present invention be exactly to provide a kind of at high temperature can be antiacid, alkali, salt, metal and metal alloy corrosion or the electric heater that corrodes.
For achieving the above object, the present invention takes following technical scheme: a kind of electric heater, it is characterized in that: it comprises the porcelain bushing of bottom end seal, be arranged on the ceramic core in the described porcelain bushing, be wrapped in the resistance wire of described ceramic core outer wall, and at the heat conductive insulating powder that is filled between described ceramic core and the described porcelain bushing.
Described ceramic core is hollow, also is filled with described heat conductive insulating powder in it.
The outer wall of described ceramic core is provided with helical groove, and described resistance wire is wrapped in the described helical groove.
Described heat conductive insulating powder is magnesium oxide powder or alumina powder.
The present invention is owing to take above design; it has the following advantages: 1, the present invention is owing to twine resistance wire in the outside wall surface of ceramic core; between ceramic core and porcelain bushing, fill the heat conductive insulating powder; therefore both can conduct heat effectively; the protective resistance silk has greatly prolonged the useful life of electric heater at high temperature not by corrosion of heat-storing materials such as acid, alkali, salt, metal and metal alloy or erosion effectively again.2, the present invention can directly imbed electric heater in the heated medium when therefore using because the protection of porcelain bushing is arranged, and realizes inner heating, reduces scattering and disappearing of heat in the heating process, improves the utilance of the efficiency of heating surface and electric energy.3, the present invention is owing to be provided with helical groove in the ceramic core outside wall surface, and resistance wire is wrapped in the helical groove, therefore when needs are changed resistance wire, can easily ceramic core be taken out together with resistance wire and put into, and can not make resistance wire and heat conductive insulating powder generation frictional impact.The present invention can be widely used in the various accumulation of heat power devices as a kind of novel electric heater.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the local enlarged diagram of ceramic core outer wall helical groove of the present invention
Embodiment
As shown in Figure 1, the present invention includes the porcelain bushing 1 of bottom end seal, be arranged on the ceramic core 2 in the porcelain bushing 1, be wrapped in the resistance wire 3 of ceramic core outer wall, and be filled in the heat conductive insulating powder 4 between ceramic core 2 and the porcelain bushing 1.
In the foregoing description, as shown in Figure 2, the outer wall of ceramic core 2 can be provided with helical groove 21, so just resistance wire 3 can be wrapped in the helical groove 21, when needs are changed resistance wire 3, can easily ceramic core 2 be taken out and put into, and can not make resistance wire 3 and heat conductive insulating powder 4 that frictional impact takes place.Simultaneously, ceramic core 2 can be hollow, fills heat conductive insulating powder 5 in ceramic core 2.
In the foregoing description, being filled in heat conductive insulating powder 4 and the heat conductive insulating powder 5 that is filled in the ceramic core 2 between porcelain bushing 1 and the ceramic core 2, can be magnesium oxide powder, or alumina powder, or other heat conductive insulating powder.
When the present invention works, by wiring 6 making current that connect resistance wire 3, when electric current passes through resistance wire 3, by Joule effect as can be known electric energy be converted into heat energy, heat energy is yearned for the transmission heat to being enclosed in electric heater of the present invention heat storage medium on every side by heat conductive insulating powder 4 and porcelain bushing 1, makes heat storage medium be embodied as the power consumption equipment accumulation of heat by phase transformation.
The various embodiments described above of the present invention only are used to illustrate technical scheme of the present invention, and it should not limit protection scope of the present invention, and the equivalent transformation as if the technical scheme of the various embodiments described above is made all should belong to protection scope of the present invention.
