At present: known infrared radiation electric heater, especially the vacuum in the heating field, pressure, liquid, gas, corrosivity, the electric heating of molten mass, all adopt the very low electrothermal tube of electric conversion efficiency, finish heating process, and the infrared directive radiator that occur the nineties, though electricity-thermal radiation transfer ratio improves widely, performance is very superior, in the heating field, obtained using widely, but, because its structural restriction can not be adopted in some above-mentioned fields, and use various types of electrothermal tubes, it is low to exist electricity-thermal conversion efficiency again, surface temperature is low, and the unit area of dissipation is little, and the loss of interior energy is big, shortcomings such as thermal inertia is big, and all are disposable uses, having caused the very big waste of the energy, element can not be reused.

The purpose of this utility model provides a kind of novel absorption infrared electric heating plate, the infrared physical efficiency infrared radiation of absorbing wavelength 1.4-2.5um effectively of being excited of its inner structural members, produce secondary excitation after being excited, and the selective absorption plating of housing, for the high wave band of visible light portion of energy, and infrared waves, strong absorption is arranged, fill in the device infrared waves is had the gas of absorption consumingly, with oxygen in the discharger, enhancing is outwards conducted heat energy to the absorption and the housing of infrared waves with the form that light comet knot touches, and has avoided the oxidation of thermal source simultaneously, prolonged useful life, formed a kind of electric conversion rate height, the surface temperature height, area of dissipation is big, the high-effect heater that thermal inertia is little, except that as the conventional heating environment, in some special occasions, embodied its value, can be applied to any heating field below 900 ℃ basically.

The purpose of this utility model is achieved in that

A kind of absorption infrared electric heating plate, its structure comprise housing, thermal source, the infrared body of being excited, and infrared-gas absorbs, and it is configured to

Housing is the flat case type container of closed, makes with the alloy material high temperature resistant, corrosion-resistant, that conductive coefficient is high, has cap seal to close, and it is high temperature resistant that its surface of internal cavity is coated with one deck, absorptivity height, the selective absorption plating that emissivity is little;

The infrared body of being excited is tabular, and the one plane is shaped on some grooves of arranging at a certain distance, form by two of the identical I of shape, II, and be the composition surface with plane, groove place, two plate groove surface opposites are to a synthetic cavity;

Thermal source is resistant to elevated temperatures resistance wire, and the rectangularity that spirals is spiral-shaped, is installed on infrared being excited in the cavity that body I and II composition surface upper groove formed;

Described infrared body I and the II of being excited is installed in together with the heat source resistor silk in the airtight inner chamber of housing, in this inner chamber and be filled with infrared absorption gas;

Connect the enclosing cover place at the housing inner chamber high temperature resistant adiabatic insulated enclosure material is housed;

In housing, be provided with the mechanism of degassing, comprise deaerator and aspirating hole;

Two winding terminals are connected with the two poles of the earth of thermal source.

Described infrared groove of being excited on the body mating surface can be V-arrangement, rectangle, semicircle and other shapes.

Described infrared body I and the II of being excited doses the material of rare element for being main carrier with the amorphous silica, the plate object that has microbubble that forms with electric arc farad system.

In sum, the utility model is by the rational deployment of various materials, and the novel structure uniqueness finally causes following actively useful effect:

1. electricity-thermal conversion efficiency height;

2. surface temperature height;

3. the unit area of dissipation is big;

4. the loss of interior energy is little;

5. thermal inertia is little;

6. life-span height.

These advantages have been improved the performance of electrothermal tube widely, and energy-saving effect has had significant raising, have formed a kind of efficient, high energy, energy-saving infrared heating device.
