Abstract
The utility model relates to an ultrathin mica electric heating member which is composed of a mica surface electric heating member with a modified surface of an insulating base material mica plate and an insulating mica plate. The utility model is characterized in that the mica surface electric heating member is in a sliver shape and is regularly arranged; a circuit uses the series connection and the parallel connection; the integral back surface is provided with reflecting aluminum foil or an insulating mica plate, the integral front surface is provided with the insulating mica plate, and then a metallic frame is added to the periphery to clamp the insulating mica plate; silver electrodes on both ends of the mica surface electric heating member uses the mechanical connection; an electrode lead is led out from the metallic frame to be connected with a power plug. The utility model has the advantages that the high thermal efficiency of the used mica surface electric heating member reaches more than 96 percent, the heat inertia is small, the radiating surface is big, the elevation of temperature is fast, the service life is long and the mica surface electric heating member can continuously work for more than tens of thousands of hours. The mica surface electric heating member and the insulating mica plate are packaged by using the non-glue technology, therefore the film burn phenomenon is not easy to happen; the electrode position uses the mechanical connection, therefore the connection is reliable; the periphery is coated by the metal, therefore the strength is enhanced. The entirety surface temperature can reach about 300 DEG C. The utility model is suitable for manufacturing various electric heating devices or electric baking devices, such as an ultra-thin radiation electric room heater, etc.
Description
Technical field
It is the Ohmic resistance heater members of feature that the utility model belongs to material composition or material character, be particularly related to the ultrathin electrothermal piece that a kind of face Electric radiant Heating Film of doping layer of surface modification on insulation resistant substrates micarex surface is made, be used for the electric boiling plate of apparatus for baking or heating installation.
Background technology
In recent years, the electrothermal device of electric baking device or electrothermal heating apparatus has the face thermo electric material of employing insulating substrate surface modification to make.Its insulating substrate adopts pottery, glass, and carborundum, multiple material such as mica, its heat efficiency is up to more than 96%, and thermal inertia is little, quick heating, the life-span is long, but continuous operation up to ten thousand hours.A kind of mica electric hot plate at present commonly used adopts mica to make base material, and the beans flour noodle Electric radiant Heating Film is oozed on the surface, constitutes the face electric hot plate, adds the protection of thin layer mica insulation plate.Because intensity is not high, the mica insulation plate is often damaged, causes the Electric radiant Heating Film of surface modification to expose, and the loss or the leakage of electric weight take place, and electrode virtually connects, and peripheral distortion easily burns film, influences safe in utilization and saves energy.
Summary of the invention
The purpose of this utility model is, design and produce a kind of ultrathin mica electrothermal piece, prepare a kind of conductive heating layer in the modification of insulating substrate micarex upper surface, adopt no adhesive process encapsulation, do not make the burning film, electrode area adopts mechanical connection, do not make collapse, peripheral metal bound edge is mentioned bulk strength, to reduce breakage, guarantee safe in utilization.
The technical scheme that the utility model adopted is, a kind of ultrathin mica electrothermal piece, mica face electrothermal piece and insulating mica plate by insulating substrate micarex surface modification are formed, its mica face electrothermal piece is elongated, regularly arranged, circuit adopts series and parallel, the whole back side is provided with reflective aluminium foil and insulating mica plate, whole front is provided with insulating mica plate, periphery adds metal edge frame and blocks, the silver electrode at mica face electrothermal piece two ends adopts mechanical connection, has contact conductor to draw from metal edge frame, connects attaching plug.
The utility model has the advantages that: the electric heating conversion superior function of giving full play to existing surface modification face electrothermal device, the heat efficiency of the face electrothermal piece that the insulating substrate micarex surface modification that is adopted is made is up to more than 96%, thermal inertia is little, radiating surface is big, quick heating, life-span is long, but continuous operation up to ten thousand hours.When the face electrothermal piece was worked under predetermined condition, the exterior insulation performance was good, and is not on fire, do not damage, and has reliable water resistance.Adopt no adhesive process encapsulation between face electrothermal piece and the mica insulation plate, be difficult for burning film, the electrode area mechanical connection, connection is reliable, peripheral metal bound edge, intensity improves greatly, and the integral surface temperature can reach about 300 ℃.Be applicable to and make various electrothermal devices, as ultrathin radiation electric heater with heating plate, rural area breeding, the greenhouse electrothermal heating apparatus of growing seedlings, educating the son, the high-temperature electric heat apparatus for baking of agricultural byproducts or making food.
