Abstract
The utility model relates to a multi-layer composite type electric heating board. Resistance wires are clamped between high heat conductivity material and heat insulation material, and far infrared material is painted on the top surface of the high heat conductivity material. Electrical heat energy generated by the resistance wires is not easy to dissipated under the cover surface of the heat insulating material; on the surface of the far infrared material, heat conductivity capability is strong, a heating object arranged on the surface of the far infrared material can receive heat energy, and therefore, the utility model has high heat energy utilization efficiency. The resistance wires covered between the materials have strong vibration resistance and low hot load strength, and therefore, the utility model has the advantage of long service life.
Description
The utility model relates to a kind of electrical heating elements, is the enclosed type electric heating element about using on electric heating appliance, the equipment.
Existing enclosed type electric heating element, be the bushing type electric heater, promptly adopt pack into the mode of insulation porcelain matter sleeve pipe of resistance wire cover, the electrical heat energy that resistance wire produces exhales in the circumference all directions equably by casing wall, usually heating object only is placed on the direction of resistance wire sleeve pipe circumference, only be received in the heat energy that exhales on this direction, the heat energy that distributes of resistance wire has only this direction for effectively like this, the heat energy of all the other directions all ineffectually scatters and disappears and consumes, therefore, the utilization efficiency of heat energy of this sleeve closure formula electrical heating elements is very low.Simultaneously on this sleeve closure formula electric heating element, resistance wire wraps in the sleeve pipe, heat-sinking capability is reduced, resistance wire unit are heat load is very big, thus the useful life of having reduced resistance wire, in addition, the position of resistance wire in sleeve pipe can not be stablized fastening, cause resistance to shock poor, damage easily, influence useful life.
The purpose of this utility model provides a kind of multi-layer combined electrical heating elements, and it can overcome the above-mentioned shortcoming of existing sleeve closure formula electrical heating elements, and a kind of multi-layer combined electrical heating elements with high efficiency of utilization and high life promptly is provided.
The purpose of this utility model is achieved in that the employing sandwich construction, resistance wire is clipped between high thermal conductivity material layer and the adiabator layer, make resistance wire closely contact and seal with this two layers of material, they form an integral body by compacting, baking, in addition spraying one deck far-infrared material on the end face of high thermal conductivity material.
When the resistance wire energized, the electrical heat energy that it produced is in insulation material surrounded this one side, because its good heat-blocking action, heat energy is difficult for scattering and disappearing, and at another side because high thermal conductivity material and the good conductive force of far-infrared material, disperse ability and have strong thermal conductance, heating object is placed on this one side, just can directly receive the heat energy that is sent, such heat energy dissipation consume is few, the unidirectional ability of effectively dispersing of another side is strong, thereby reaches the high purpose of effective utilization rate of thermal energy.
Because resistance wire closely is clipped between high thermal conductivity material and the insulation material, therefore resistance wire is able to firm fixation, and have strong antivibration, anti-collision ability, not fragile, moreover owing to adopted high thermal conductivity material and far-infrared material, cover on the one side of resistance wire, its thermal conductivity is strong, the strong load of resistance wire heat is alleviated, thereby prolonged the useful life of resistance wire.
Because adopt above-mentioned technical scheme, the utility model has overcome described every shortcoming of existing sleeve closure formula electric heating element, and a kind of multi-layer combined electrical heating elements with high efficiency of utilization and high useful life is provided.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is a profile of the present utility model, among the figure:
1, insulation material 2, resistance wire 3, high thermal conductivity material
4, far-infrared material 5, sleeve pipe 6, power supply lead wire
In the accompanying drawing, form basic structure for 1 three layers by high thermal conductivity material 3 resistance wires 2 and insulation material.Power supply lead wire 6 is in order to external power supply; inner and resistance wire 2 terminations link; the outer race of power supply lead wire 6 is with sleeve pipe 5; in order to protection power supply lead wire 6; on the bottom below the resistance wire 2 and its circumference is insulation material 1; be high thermal conductivity material 3 on the top of resistance wire 2 and the circumference thereof, the end face of high thermal conductivity material is coated with far-infrared material 4.
When making assembling, at first insulation material 1 is mixed with and does wet suitable slurry, put into die cavity, floating, resistance wire 2 with typing lies in insulation material 1 upper surface again, and be pressed in the insulation material 1, compression distance is half of resistance wire 2 diameters, will prepare the high thermal conductivity material 3 of doing the suitable slurry that wets again and put into die cavity, makes it to combine well with insulation material 1, resistance wire 2 is closely wrapped in the centre of two kinds of materials, preparation places power supply lead wire 6 and peripheral sleeve pipe 5 thereof in die cavity, through compacting, is baked into a solid integral body, at last far-infrared material 4 is sprayed on the top surface of high thermal conductivity material 3, promptly becomes multi-layer combined electric hot plate.
Claims (1)
- A kind of multi-layer combined electric hot plate is characterized in that: be a multilayer architecture, resistance wire is clipped between high thermal conductivity material layer and the adiabator layer, spraying one deck far-infrared material on the outer end face of high thermal conductivity material layer.
