Problems solved by technology

In this method, eddy currents occur on metal utensils. The eddy currents cause metal molecules to move at high speed and irregularly, and the molecules collide and rub against each other to generate heat energy. However, the molecular collision and friction processes in this way will destroy the molecular structure of food, and cannot maintain the original taste and taste of food. It nourishes, and at work produces radiation of low-frequency electromagnetic waves
However, the electromagnetic field converts the heat into an intermittent heating method, the heating is not continuous enough, the controllability of the temperature is not strong, and it does not have some high-temperature stir-frying effects
And only metal utensils can be used, which brings serious pollution of heavy metals to food
[0005] The third type is nickel-chromium wire electric ceramic furnace. In this way, the nickel-chromium wire on the furnace plate is energized and heated to generate direct heat energy. However, because the nickel-chromium wire generally has a service life of 1-3 years at high temperature, the aging of the nickel-chromium wire The process is fast, and the furnace plate where the nickel-chromium wire is placed is in a long-term high-temperature state. After the dust on the furnace plate falls into the gap between the high-temperature heating wires, the open flame will instantly fuse the heating wires.
However, the hot pressing sintering of the existing technology has low production capacity and high cost, making it extremely difficult to achieve mass production
Moreover, the thermal expansion coefficients of tungsten wire and silicon nitride are quite different, and the components may burst when heating, and the reliability needs to be improved.
In addition, the heating wires or heating sheets used in the prior art generally have insufficient thermal efficiency, and the energy consumption is relatively serious, resulting in unnecessary waste of electric energy
[0007] There are many deficiencies in the heating methods used in the prior art. In addition, social development and life have put forward higher requirements for green electricity consumption environment and healthy energy-saving lifestyle. An unprecedented qualitative change is urgently needed

Embodiment Construction

[0037] Such as figure 1 As shown, the heating device of the present invention includes an insulating base layer 1, a titanium diboride semiconductor film layer 2 is sputtered on one surface of the insulating base layer 1, and outside the titanium diboride semiconductor film layer 2 An anti-oxidation and insulating protective film layer 3 is sputtered. Specifically, the insulating base layer 1 is an alumina ceramic base layer. The anti-oxidation and insulating protective film layer 3 is an aluminum oxide film layer. The thickness range of the titanium diboride semiconductor film layer 2 is 0.1-10 µm, which can be set according to actual needs. The thickness of the insulating base layer 1 is 0.5-3 mm.

[0038] Here, the coefficient of thermal expansion of alumina is 7.85×10 -6 m / m.k, while the thermal expansion coefficient of titanium diboride is 8.1×10 -6 m / m.k, the thermal expansion coefficients of the two are very similar. When the two are combined as the materials of t...

Description

technical field [0001] The invention relates to the field of high-temperature heating equipment, in particular to a heating device, a preparation method of the device and high-temperature heating equipment including the heating device. Background technique [0002] At present, the heating methods of the heating cooker in the prior art mainly include the following methods. [0003] One is conventional coal gas or natural gas burning heat. However, this method based on direct combustion of gas and natural gas will emit a large amount of carbon dioxide, and carbon dioxide permeates the living environment, causing environmental pollution and bringing unsafe factors. [0004] The second is that the electromagnetic field of the induction cooker converts heat. In this method, eddy currents occur on metal utensils. The eddy currents cause metal molecules to move at high speed and irregularly, and the molecules collide and rub against each other to generate heat energy. However, th...
