Abstract

The utility model belongs to an improved new electric film heating device, connected by a heating body through an electrified loop; thereinto, said heating body is constituted of high temperature-resistant insulated carriers coated of an electric heating film on both upper and lower sides, the high temperature-resistant insulated carrier which forms the heating body is at least one, on the base of indirect heating, this new electric film heating device adopts the measure to coat the insulated carrier on both sides, so that the power load on the electric heating film of unit area is greatly decreased, the electric heating film is also coated on the back of heated object, high temperature-resistant and high heat conductive electric conductive glue can adhibit one face of the electric heating film with the heated object, thus the efficiency of energy use is increased; a heat isolation reflective layer is added at the bottom of the insulated carrier, the heat emitted by the two electric heating films of the insulated carrier is radiated in the direction of the heated object; the problem of heat dissipation on the other surface of the electric heating film is resolved.

Description

A kind of new electrically heating film heating device

Technical field:

The utility model belongs to improved a kind of new electrically heating film heating device.

Technical background:

Existing device for heating electric heating membrane, because of Electric radiant Heating Film can not lasting stability high temperature resistant, therefore people directly are coated in Electric radiant Heating Film on the heating object, perhaps Electric radiant Heating Film is coated on the insulating carrier, re-using high efficiency heat-conducting layer is bonded together insulating carrier and heating object, so that the heat that Electric radiant Heating Film is sent can be pulled away rapidly, prolong the useful life of Electric radiant Heating Film.But because existing device for heating electric heating membrane is simultaneously to film in certain of insulating carrier, the Electric radiant Heating Film area that is used to generate heat is limited, the power burden that makes the Electric radiant Heating Film of unit are bear is very big, even use the high efficient heat medium to take away heat rapidly like this, still can't perform to the higher limit useful life of Electric radiant Heating Film; And the limitation because of the Electric radiant Heating Film heating power of unit are can't make the power of existing device for heating electric heating membrane reach more high-grade.

The utility model content:

The purpose of this utility model is: overcome existing Electric radiant Heating Film unit are and can bear the limited limitation problem of bringing of power burden, provide a kind of new electrically heating film heating device to prolong its useful life, the power output of this heater is improved.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of new electrically heating film heating device, it is formed by connecting by power circuit by heater, wherein said heater is made up of the high-temperature insulation carrier, and the upper and lower surface of described high-temperature insulation carrier all scribbles Electric radiant Heating Film.

The high-temperature insulation carrier that the upper and lower surface of forming described heater scribbles Electric radiant Heating Film has a slice at least.

The beneficial effects of the utility model are: be formed by connecting by power circuit by heater; Wherein said heater is made up of the high-temperature insulation carrier that upper and lower surface all scribbles Electric radiant Heating Film, and the high-temperature insulation carrier that the upper and lower surface of forming heater scribbles Electric radiant Heating Film has a slice at least, so a kind of new electrically heating film heating device is on the basis that utilizes the indirect mode, employing is carried out two-sided measure of filming to insulating carrier, and the power burden that makes the unit are Electric radiant Heating Film be born reduces significantly.Spray Electric radiant Heating Film equally at the heating object back side, and use the conductive viscose resistant to elevated temperatures, that heat transfer efficiency is high that the Electric radiant Heating Film one side is bonded together with heating object, improved energy utilization efficiency; Below the one side of insulating carrier under, increase heat and isolate the reflector, make heat that insulating carrier two sides Electric radiant Heating Film sent all to the direction radiation of heating object place; Solved the heat dissipation problem that the another side Electric radiant Heating Film is sent.

Description of drawings:

Fig. 1 scribbles the device for heating electric heating membrane schematic diagram of the insulating carrier of Electric radiant Heating Film as heater for using monolithic.

Fig. 2 forms the whole device for heating electric heating membrane schematic diagram of heating for the insulating carrier that uses multi-disc to scribble Electric radiant Heating Film.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, Fig. 1 is to use the Electric radiant Heating Film electro-heat equipment of monolithic insulating carrier as heater, be that example is elaborated with the monolithic insulating carrier earlier: the utility model comprises that upper and lower surface all scribbles the insulating carrier 3 and the power circuit 5 of Electric radiant Heating Film 6, scribbling the one side that the insulating carrier 3 of Electric radiant Heating Film 6 makes progress is bonded on the heating object 1, heating object 1 back side also scribbles Electric radiant Heating Film 6, between one side that the insulating carrier 3 that scribbles Electric radiant Heating Film 6 makes progress and heating object, scribble high temperature resistant, high thermal conductivity conductive viscose 2 is equipped with heat and isolates reflector 4 below the downward one side of the insulating carrier 3 that scribbles Electric radiant Heating Film 6.The insulating carrier 3 that scribbles Electric radiant Heating Film 6 fully contacts by conductive viscose 2 high temperature resistant, high thermal conductivity with heating object 1, and the heat that makes Electric radiant Heating Film 6 produce is taken away rapidly by heating object 1.Heat is isolated reflector 4 can make the reflect heat that will scribble insulating carrier 3 downward radiations of Electric radiant Heating Film 6 be upwards radiation, has overcome the problem of heat dissipation.

As shown in Figure 2, use the heating formed by the electrothermal membrane insulative carrier 3 of polylith whole 7 to replace monolithic among Fig. 1 to scribble the insulating carrier 3 of Electric radiant Heating Film 6, can make the multilayer device for heating electric heating membrane.

The utility model utilizes existing technology, and heat-conducting medium is coated in the one side that the heating object back side or electrothermal membrane insulative carrier are gone up most, before not solidifying electrothermal membrane insulative carrier and heating object pressed with, constitute high efficiency heat-conducting medium layer.Utilize the heat-conducting medium layer to make seamless contact the between heating object and Electric radiant Heating Film like this, guaranteed its heat transfer efficiency.

This heat-conducting medium use is high temperature resistant, the conductive viscose of high thermal conductivity; The insulating carrier 3 that scribbles Electric radiant Heating Film 6 is resistant to elevated temperatures insulating material, as: devitrified glass, pottery, quartz etc.; It is silicic acid board that heat is isolated reflector 4, and this heat is isolated reflector on the one hand can the high efficiency reflective thermal radiation, can play the effect of partiting thermal insulation and protection Electric radiant Heating Film on the other hand, makes this heater safer reliably.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
