Abstract
The present invention belongs to an electrothermal film heating device. The invention aims to solve the problems of low heat conduction efficiency, high film temperature, easy oxidation and short service life of the existing electrothermal film when the existing electrothermal film is used for indirect heating. The heating device comprises an insulated carrier coated with an electrothermal film and an electrothermal film electrifying loop, wherein the back surface of the electrothermal film insulated carrier is attached to a heated object, and a metal powder heat-conducting medium layer is adhered between the back surface of the electrothermal film insulated carrier and the heated object. The invention has simple structure, long service life, high heat conduction efficiency and wide application range, can improve the power density of the electrothermal film, and is particularly suitable for heating various pipelines in oil fields.
Description
The invention belongs to a kind of device for heating electric heating membrane.
Existing Electric radiant Heating Film heating technique, because of Electric radiant Heating Film can not lasting stability ground high temperature resistant, therefore can only directly be coated in Electric radiant Heating Film on the heating object, the heat that Electric radiant Heating Film is sent can be taken away rapidly, increase the service life, scribble Electric radiant Heating Film and product such as the click coffee kettle made, saucepan, chafing dish as the back side of on the market glass, pottery, enamel ware.For widening the range of application of Electric radiant Heating Film, people are attempting adopting Electric radiant Heating Film are being coated on the insulating carrier, insulating carrier is fitted on the heating object, realize the indirect of Electric radiant Heating Film, but because heating object and the roughness on insulating carrier surface and the error of physical dimension, make insulating carrier can not fully contact with heating object, the heat that Electric radiant Heating Film is sent can not be taken away rapidly, film temperature is raise, accelerated oxidation, heat transfer efficiency is low, useful life is short, causes Electric radiant Heating Film to be difficult to be applied to indirect.
The objective of the invention is to solve above-mentioned topic, a kind of mode of utilizing indirect is provided, and the heat transfer efficiency height, the device for heating electric heating membrane of long service life.
The present invention includes the insulating carrier and the Electric radiant Heating Film power circuit that scribble Electric radiant Heating Film, the back side of electrothermal membrane insulative carrier is fitted on the heating object, the sticking metal dust heat-conducting medium layer that scribbles between the electrothermal membrane insulative carrier back side and heating object.
The present invention is simple in structure, long service life, heat transfer efficiency height, applied range, and can improve the power density of Electric radiant Heating Film, is particularly suitable in the oil field various pipelines heating and uses.
Fig. 1 is a structural representation of the present invention;
Fig. 2 has the structural representation of heat-insulating layer for the present invention.
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes the insulating carrier 3 and the Electric radiant Heating Film power circuit 4 that scribble Electric radiant Heating Film 5, the back side of electrothermal membrane insulative carrier 3 is fitted on the heating object 1, the sticking metal dust heat-conducting medium layer 2 that scribbles between the back side of electrothermal membrane insulative carrier 3 and heating object 1.Because metal dust heat-conducting medium 2 can fully contact with heating object 1 with insulating carrier 3, therefore, insulating carrier 3 fully contacts with heating object 1 by metal dust heat-conducting medium 2, form a heat conduction integral body, the heat that Electric radiant Heating Film 5 produces is taken away the Electric radiant Heating Film long service life rapidly by heating object.And adopt this mode of heating, and can improve the power density of Electric radiant Heating Film, widened the application of Electric radiant Heating Film.
The present invention with adhesive furnishing thick shape, is coated on the heating object or the back side of electrothermal membrane insulative carrier metal dust, before not solidifying with electrothermal membrane insulative carrier and heating object pressing, formation metal dust heat-conducting medium layer.Make metal dust fully be filled in its gap the heat transfer efficiency height like this.
Adhesive can add gasoline or banana oil or other solvent and be in harmonious proportion with varnish or novolaks or alkyd resin coating or epoxy resin coating or 1032 lacquers.Also can adopt other heat-resistant adhesive.With adhesive and metal dust mixing, and the thick shape of furnishing is sticking is coated with, and after the pressing, treats that it solidifies.
Electrothermal membrane insulative carrier 3 is made by non-metal insulating material, as pottery, glass, mica products etc.It also can be made by enamel.Can make its corresponding electrothermal membrane insulative carrier according to the difformity of heating object.
As shown in Figure 2, on Electric radiant Heating Film 5, be provided with heat-insulating layer 7, make the heater safety and reliability.Between heat-insulating layer 7 and Electric radiant Heating Film 5, be provided with mica protective layer 6, with the protection Electric radiant Heating Film.
