Abstract
The utility model relates to a film heater, which comprises a metal base, wherein one surface of the metal base is provided with an insulating layer and an electric heating filming layer is plated on the insulating layer. Both sides of the electric heating filming layer are provided with electrodes connected with the electric heating filming layer electrically. The electric heating filming layer heats for reaching the purpose of heating through the electric conduction of the electrodes. The film heater has the advantages of better structure strength, quick, even and safe heating and high heat efficiency.
Description
Technical field
The utility model relates to a kind of thin film heater.
Background technology
Traditional in the past heater generally is to utilize nichrome coils or quartz ampoule to be positioned over to be heated the place, owing to must carry out heat conduction by air during its heating, yet because the aerial conduction efficiency of heat energy is relatively poor, therefore the uneven situation of heating-up temperature can appear.Heater in the market generally is the mode that adopts the Electric radiant Heating Film heating because Electric radiant Heating Film need not be done biography, the heat conduction of secondary in use, thereby this class heater have heating fast, evenly, safety and the high advantage of the heat efficiency.For example No. 472997 patent documentation of Taiwan patent gazette on January 11st, 2002 discloses a kind of heater that comprises an Electric radiant Heating Film at least; this heater comprises a substrate; one elargol and an electrode; has a far infrared layer on the one side of wherein said substrate; has an electric membranous layer on the another side of described substrate; has a conductive protecting layer on the described electric membranous layer; and this conductive protecting layer has the monoxide surface; described elargol is positioned at the precalculated position on this conductive protecting layer; realize inner the electric connection with this conductive protecting layer; described electrode is realized electric connection with described electric membranous layer by conductive protecting layer and elargol, and electric membranous layer and the collocation of far infrared layer are to realize carrying out high efficiency heating to heating thing.
In addition, the patent documentation that No. the 238409th, the Taiwan patent gazette in January 11 nineteen ninety-five also discloses a kind of heater with semiconductor thermoelectric film, this heater is to comprise gold, the compound of metallic elements such as silver or its organic compound are as base material, in the process of making Electric radiant Heating Film, at first with certain proportion modulation antimony, elements such as iron are even as the dopant mix, insert in the high temperature furnace chamber after then base material being cleaned up, make substrate surface produce activation phenomenon, again that aforementioned blending is appropriate fluent material, quantitatively be injected in this high temperature furnace chamber through air mixed, the charged ion of mist-like was resolved in atomizing immediately after the electric conducting material fluid was sprayed into, and be coated in the surface of base material equably, or directly spray invests the substrate surface that has activated, with the integrally formed semiconduction heating film of base material.Yet, this class is the heater of heating source with the Electric radiant Heating Film, its base material is necessary for insulator, to avoid the base material conduction, so existing technology mostly adopts resistant to elevated temperatures ceramic material base material, yet its structural strength of ceramic material base material is relatively poor, and easily break or lack, in addition, adopt the heater of printed resistor material as heating film because of thermal shock, collision or other factors produce, also can be inhomogeneous because of the composition composition or the crystal grain of resistance material, influence the stability in use of heater.
The utility model content
The purpose of this utility model be to provide a kind of have heating fast, evenly, safety and the high thin film heater of the heat efficiency.
Above-mentioned purpose of the present utility model is by providing a kind of thin film heater with following structure to realize, this thin film heater comprises: a metallic substrates, one side in this metallic substrates is provided with insulating barrier, on described insulating barrier, be coated with one deck electric heating coatings, the both sides of described electric heating coatings have the electrode with its electrically connect respectively, by electrodes conduct the electric heating coatings are generated heat and reach the purpose of heating.
Adopt the thin film heater of this structure, because it adopts metal material as substrate, so have preferable structural strength, in addition, electric heating coatings and insulating barrier by high temperature mutually the mode of counterdiffusion with the molecular link combination, avoided conventional press, extruded modification and when the bad phenomenon of temperature temperature difference that produces when moment sharply raises, thus realize heater heats fast, even, safety and the high effect of the heat efficiency.
Description of drawings
Fig. 1 is the vertical view of the specific embodiment of thin film heater of the present utility model.
Fig. 2 is the end view of the specific embodiment of thin film heater of the present utility model.
Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings.
As shown in Figure 2, thin film heater of the present utility model comprises: metallic substrates 1, be positioned at the insulating barrier 2 on the surface of metallic substrates 1, and one deck electric heating coatings 3 is arranged on the surface of insulating barrier 2, the both sides of electric heating coatings 3 have the electrode 4 with its electrically connect.
Adopt metal material as substrate 1, have preferable structural strength.The material of insulating barrier 2 is an inorganic matter, in order to separate metallic substrates 1 and electric heating coatings 3, to avoid metallic substrates 1 conduction, the method that forms the electric heating coatings on insulating barrier 2 is the thermal chemical reaction method, electric heating coatings 3 and insulating barrier 2 by high temperature mutually the mode of counterdiffusion with the molecular link combination, the material of electric heating coatings 3 adopts tin, nickel-chromium alloy, copper-nickel alloy, copper-nickel-manganese alloy etc., thickness makes electric heating coatings 3 heatings reach the purpose of heating by electrode 4 conductions usually less than 2 μ m during heater work.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
