The purpose of this utility model is achieved in that
A kind of electric heater comprises that the skeleton and the power supply that are wound with heating wire insert mechanism, is provided with framework, is the skeleton that is wound with heating wire in the framework, and the skeleton that is wound with heating wire is provided with reinforcing mat; Be wound with between the skeleton of heating wire and the reinforcing mat and be filled with heat-resistant insulation material.
On the basis of technique scheme, the utility model also has following further technical scheme:
Be filled with infrared coating on the one or both sides of described reinforcing mat.
Described reinforcing mat is woven wire or carbon fibre web, glass fiber mesh.
The described skeleton that is wound with heating wire is ceramic skeleton or mica frame, or the heat resistant plastice skeleton, or resin matrix, or the organic silicon rubber skeleton.
The electric hot plate of framework and the skeleton formation platy structure that is wound with heating wire, the electric hot plate thickness 5-10 millimeter of described platy structure.
Framework can constitute electric heating coil or electric heating bar with the skeleton that is wound with heating wire.
Described framework is a hollow structure.
Advantage of the present utility model is as follows:
Because, in the framework skeleton that is wound with heating wire, the skeleton that is wound with heating wire is provided with reinforcing mat; Be wound with between the skeleton of heating wire and reinforcing mat heat-resistant insulation material is arranged.So coating, filler and reinforcing mat and the skeleton that is wound with heating wire combine back intensity and increase substantially, can bear sharp pounding, jolt and can not damage; In use, though the surface burn rubescent warpage or the cracking of all being not easy; Product can burn till below 500 ℃, helps reducing the manufacturing cost of product.The utility model is well suited for making the electric heater that power is big, temperature is high, and has the intensity height, vibration resistance, the advantage of being convenient to transport.The utility model also is fit to make the electric heater that power is big, temperature is high, and the advantage that has intensity height, vibration resistance and be convenient to transport, be particularly useful for industrial electro heating environments such as nuclear power, mould, injection moulding, electronics, medicine, pipeline, packing, weaving, be widely used in industry, agricultural, the dehydration in each field of people's lives, drying, heating.As, paint curing, be applicable to drying room, the drying tunnel of automobile, motorcycle; The textile printing and dyeing production line; Electronics PCB Production line; The reactor heating of chemical industry; Grain heat-drying, nut drying, Tea Processing, the drying of Chinese herbal medicine, the deep processing of various agricultural byproducts; Disinfection cabinet in the life, kitchen tools manufacturings such as electric rice cooker etc.Cryogenic product is fit to people's heating, health-care physiotherapeutic articles for use, animals and plants insulation etc.
The utility model takes to also have following advantage behind the further step:
When described coating is coated on both sides, can carry out two-sided heating, increase twice heating surface.
When described reinforcing mat is stainless steel cloth or carbon fibre web or glass fiber mesh, can improve the frame strength that is wound with heating wire, and coating also difficult drop-off or cracking.
When described coating is infrared coating, can be radiation infrared, help strengthening heats.
When the skeleton that is wound with heating wire is ceramic skeleton, help making high temperature, large-area electric hot plate; The skeleton that is wound with heating wire is a mica frame, or the heat resistant plastice skeleton, or resin matrix, or during the organic silicon rubber skeleton, helps making low temperature, large-area electric hot plate.
When described framework is hollow structure, not only can alleviate the weight of framework, and not yielding.
