In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Fig. 1 is a schematic diagram of a component of a planar radiation source according to an embodiment of the present invention, and fig. 2 is an exploded schematic diagram of a component of a planar radiation source according to an embodiment of the present invention, as shown in fig. 1 and 2, which includes an electric furnace wire (not shown in fig. 1 and 2), a plurality of heat conduction members 20, and a radiation surface 30.
Resistance wires are generally adopted as heating elements of a surface type radiation source in the prior art, but the working temperature is low, and the actual requirements cannot be met. In the embodiment of the invention, the electric furnace wire (the electric furnace wire is generally made of iron-chromium-aluminum and nickel-chromium electric heating alloy wires which are wound and molded by a high-speed winding machine) is used as the heating element of the surface type radiation source, the working temperature of the electric furnace wire is high (up to 1400 ℃), the service life is long, the allowable surface load is large, the oxidation resistance is good, the resistance is stable, and the cost is low. As a preferable scheme, an electric wire reel 40 for placing an electric wire may be provided, and the electric wire reel 40 is made of a high temperature resistant material and may have a groove for placing an electric wire. It is understood that the electric wire reel 40 on which the electric wire is placed is disposed at the center of the surface type radiation source.
In addition, in the embodiment of the invention, the heat can be transferred by adopting a conduction mode instead of a radiation mode in the prior art. Specifically, a plurality of heat conductive members 20 are installed between the electric furnace wires and the radiation surface 30. Preferably, in some embodiments, the thermally conductive member 20 may be a fin (generally, a fin is a metal sheet with high thermal conductivity that increases the surface of the device that requires heat transfer), and the material of which is made may be copper. It is understood that the heat conducting member 20 may be formed in other shapes and may be made of other metal materials, and the present invention is not limited thereto. In some embodiments, the heat conductive member 20 has one end in contact with the electric furnace wire to enable heat conduction and the other end fixedly connected to the radiation surface 30. In other embodiments, the heat conduction member 20 conducts heat to the heater wire through the heat conduction sheet 50, i.e., one end of the heat conduction member 20 is in contact with the heat conduction sheet 50, the heat conduction sheet 50 is in contact with the heater wire, and the other end of the heat conduction member 20 is fixedly connected to the radiation surface 30. In a specific application, the heat conduction member 20 and the radiation surface 30 may be integrally designed. The heat conductive sheet 50 is generally made of a material having electrical insulation with low loss of heat resistance.
With the above arrangement, the present invention can achieve heat transfer from the electric furnace wire to the radiation surface 30 in a conduction manner, and since the conduction manner transfers heat through thermal movement of a large number of molecules in the substance, the heat transfer efficiency thereof is much higher than that of the radiation manner. In this way, efficient heating of the radiation surface 30 can be ensured.
Preferably, in some embodiments, the radiating surface 30 may be provided with a thermal insulating material to maintain temperature stability except for the portion connected with the heat conductive member 20.

step S301: and determining the heat required by the radiation surface in the temperature rising process according to the mass, the specific heat capacity and the working temperature of the radiation surface.
In this step, the heat required for heating the radiation surface can be obtained by multiplying the mass of the radiation surface, the specific heat capacity of the radiation surface and the temperature change value of the radiation surface by using a heat formula. Wherein the mass of the radiating surface may be obtained by multiplying the volume by the density, and the temperature variation value may be a difference between an operating temperature (e.g., 900 degrees celsius) and an initial temperature (e.g., room temperature).
Step S302: and dividing the determined heat by the required temperature rise time to obtain the power of the electric furnace wire.
The temperature rise time may be a predetermined index. Through the steps, the power of the electric furnace wire suitable for the surface type radiation source can be determined.

Simultaneously, can be with the direct and electric stove silk contact of a plurality of heat-conduction components (also can contact heat-conduction component and conducting strip, contact conducting strip and electric stove silk, thereby realize the heat-conduction between heat-conduction component and the electric stove silk), and with heat traditional component and radiant surface fixed connection, can realize the heat from the electric stove silk to the quick transmission of radiant surface with heat-conduction mode like this, make the radiant surface can high-efficient intensification, the demand to high-efficient high temperature face type radiation source in the practical application has been satisfied, the slower defect of face type radiation source intensification among the prior art has been solved. In addition, the heat conduction process of the electric furnace wire, the heat conduction component (such as a copper fin) and other parts is simple, and the cost is low, so that the surface type radiation source provided by the invention has high practical value and popularization prospect.
