Further, the carbon nano heating element is detachably connected with the container body. By adopting the technical scheme, the maintenance cost between the heating element and the container body is reduced.
Other contents not described in this embodiment may refer to embodiment one.
The traditional metal heating wire and heating bar are generally used by being packaged in a tube through MgO powder, and the metal heating wire or the carbon fiber heating wire is also made into a tubular shape and then fixed on a container, such as an electric kettle, a soybean milk machine and other products. However, the carbon nanotube film is a heating element which can uniformly heat as thin as 5um, and the carbon nanotube film is soft and can be bent at will, so that the electrothermal conversion efficiency of the carbon nanotube film is more than 99% when the carbon nanotube film is used as a heating element; wherein the electrothermal radiation efficiency reaches 60%; the temperature of the heating body is much lower than that of the resistance wire under the same temperature; the heating temperature of the electric heating element can reach 1200 ℃ in a closed environment; and the heat conductivity coefficient of the ceramic material is more than 5000W/mk, so that the ceramic material can uniformly generate heat.
Because the carbon nano tube film is very thin and only about 5-10 um, the thermal inertia of the electric heating element of the carbon nano film is small, and the heat conduction is fast. The surface is heated and the heating is uniform, the heat transfer temperature difference is small when the heating element is used, and the heated object is not easy to stick on the pan.
The carbon nanotube film can be provided with a temperature detection and protection device, such as a temperature sensor, a temperature controller, a fuse link and the like, after being installed, so that the temperature of the heating element can be detected, the power of the heating element can be controlled, the temperature of the heating element can be prevented from being too high, and the situations of dry burning, overheating, bottom pasting in a heated container and the like of a product can be avoided.
The carbon nanotube heating element can be disposed on a spherical or cylindrical-like container due to its flexible and heel-shaped characteristics, and of course, can be disposed on a plane or a rectangular container, and the rectangular container should have a round angle larger than R0.5. The electric rice box is suitable for being arranged on a spherical body and a plane, such as the bottom surface and the side surface of a cup body of a soybean milk machine, the bottom surface and the side surface of an electric rice cooker and the bottom side surface of the electric rice box; the effect of three-dimensional heating is achieved.
The carbon nanotube heating element can be directly arranged on the insulating surface of the non-metal container, such as on a transparent glass surface and a ceramic plate, and the carbon nanotube is directly packaged on the insulating container.
Thus, not only the space occupied for heating is reduced, but also the heat capacity of the whole heating part is reduced and the volume is reduced; the heat transfer efficiency is improved. And the heat transfer area can be enlarged by utilizing the carbon nano tube, so that the temperature of a heating part is reduced and the pan pasting is lightened under the condition of the same heat transfer power.
Other embodiments of the present invention than the preferred embodiments described above will be apparent to those skilled in the art from the present invention, and various changes and modifications can be made therein without departing from the spirit of the present invention as defined in the appended claims.
