Abstract
The utility model discloses a metal electric heating plate. The electric heating plate is connected with a temperature protector for avoiding over-high temperatures; a composite layer structure of the electric heating plate is sequentially composed of a first insulation medium, the electric heating plate and a second insulation medium, wherein the first insulation medium is an NAL (Net Abstraction Layer) substrate and the electric heating plate is a metal electric heating film; the second insulation medium is an insulating and heat-radiating coating; the metal electric heating film is directly stuck on the NAL substrate and the insulating and heat-radiating coating is directly coated on the metal electric heating film and the NAL substrate, and the insulating and heat-radiating coating is a mixture of polyvinyl acetate and quartz powder. The metal electric heating plate provided by the utility model has the advantages of simple structure and convenience, safety in use and good heat radiation and preservation effects; the metal electric heating plate can be prepared into indoor decoration plates according to demands or is placed on a writing tabletop to be used as an electric heater; and furthermore, the metal electric heating plate can be widely applied to fields needing to bake and dry.
Description
Technical field
The utility model relates to a kind of electric calorifie installation through resistance heating, relates in particular to a kind of metal electric hot plate that utilizes non-metallic conducting material as electric heating element.
Background technology
Existing electric heater, the single face hierarchical structure that its electric hot plate adopts is metallic plate, insulating adhesive, mica paper, composite conductive thin film and mica paper, wherein, meets conductive film and can select metal electric heating membrane for use, like metal foiled paper.But there is following shortcoming in this structure: the one, and layer of structure is many, and technology is comparatively complicated, and weight is big, cost is high; But this structure and Material Selection make the security performance of electric heater can not get ensureing that applicable scope is restricted; The 3rd, electric hot plate can not use separately, must with could use after case combines.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of electrical safety performance good, light weight and the metal electric hot plate that dispels the heat even, simple in structure.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:
A kind of metal electric hot plate is connected with the temperature protector of avoiding temperature too high on this electric hot plate, the lamination layer structure of electric hot plate is followed successively by first dielectric, metal electric hot plate and second dielectric; Said first dielectric is the NAL substrate, and the metal electric hot plate is a metal electric heating membrane, and second dielectric is insulation, heat radiation coating; Metal electric heating membrane directly sticks on the NAL substrate, and insulation, heat radiation coating directly are coated on metal electric heating membrane and the NAL substrate; Said insulation, heat radiation coating are the mixture of polyvinyl acetate and silica flour.
Temperature protector can be when electric plate temperature be too high, to the use of electric hot plate protection is provided; The NAL substrate has insulation, suffocate and characteristic such as insulation, and its one side that is pasted with metal electric heating membrane is the plane; Metal electric heating membrane requires design according to circuit design; Insulation, heat radiation coating directly is coated in the oxidation that can avoid metal electric heating membrane on metal electric heating membrane and the NAL substrate, can also make between the metal electric heating membrane and isolate, and plays arcing effect on fire between the metal electric heating membrane circuit that inhibition causes because of reasons such as short circuits.The mixture of polyvinyl acetate and silica flour can increase by second insulating barrier thermal diffusivity and with the conductibility of heat, overcome the metal electric heating membrane uneven weakness of generating heat, make whole electric hot plate heat distribution balanced.
Beneficial effect: the metal electric hot plate that the utility model provides, simple in structure, light, safe in utilization; Heat radiation, high insulating effect; And can process Indoor decorative plate as required, or place on the writing surface as electric heater and use, also can be widely used in the field that needs baking or oven dry.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be depicted as a kind of metal electric hot plate like accompanying drawing 1, on this electric hot plate, be connected with the temperature protector of avoiding temperature too high, the lamination layer structure of electric hot plate is followed successively by first dielectric, metal electric hot plate and second dielectric; Said first dielectric is a NAL substrate 1, and the metal electric hot plate is that metal electric heating membrane 2, the second dielectrics are insulation, heat radiation coating 3; Metal electric heating membrane 2 directly sticks on the NAL substrate 1, and insulation, heat radiation coating 3 directly are coated on metal electric heating membrane 2 and the NAL substrate 1; Said insulation, heat radiation coating 3 are the mixture of polyvinyl acetate and silica flour.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
