Abstract

The invention discloses a heating device with the bottom part, the lateral part and the top part being heated simultaneously, which comprises a lower base body (1) and an upper base body (2), and is characterized in that the upper surface of the upper base body (2), the outer surface of a side wall (3) of the lower base body (1) and the lower surface of a bottom plate (4) of the lower base body (1) are provided with an electrothermal film (5), and the electrothermal film is formed by such components as stannic chloride, titanium trichloride, antimony trichloride, calcium chloride, chromium oxide, manganese dioxide, nickel oxide, isopropyl alcohol, ethanol and water; the components are mixed and prepared into an electrothermal film treatment solution, then the electrothermal film treatment solution is sprayed to the surface of the heated base bodies, annealing is carried out, and then a finished product of the electrothermal film is acquired after electrode processing. The invention further discloses a heating method of the device. The heating device and the heating method have the beneficial effects that the electrothermal film is not easy to fall, the upper temperature limit of the electrothermal film is improved, and the temperature of the heated base bodies is enabled to rise quickly; the highest surface operating temperature can reach 800 DEG C, the power density can reach 30W / cm2, and the service life can reach up to 20000 hours.

Description

technical field [0001] The invention relates to the technical field of electrothermal film heating devices, in particular to a heating device and a heating method for simultaneously heating a bottom, a side and a top. Background technique [0002] Most of the electric heating film in the prior art has the surface temperature of the electric heating film is too low, it is difficult to realize the electric heating film technology in the high temperature stage, and it is only suitable for the working conditions of low temperature and slow heating; moreover, its heating performance is unstable, and it can be used for a long time. During the working process of time use, the heating power is easy to attenuate; the adhesion between the electric heating film and the substrate is poor, it is easy to fall off, and the actual service life is short. [0003] In addition, the electric heating film variable power heating technology in the prior art, such as a multi-power energy-saving ele...
