Abstract

The invention discloses a heating device capable of simultaneously heating from a bottom part and lateral parts. The heating device comprises a base body (1), wherein the base body (1) comprises a cylindrical lateral wall (2) and a bottom plate (3), wherein electrothermal films (4) are arranged on the outer surface of the lateral wall (2) and the lower surface of the bottom plate (3); each electrothermal film is prepared from the following components: stannic chloride, titanium trichloride, antimony trichloride, calcium dichloride, dichromium trioxide, manganese dioxide, nickel sesquioxide, isopropyl alcohol, ethanol and 20-30 parts of water; the components are mixed to prepare electrothermal film treating liquid; and the electrothermal film treating liquid is sprayed on the surface of the heated base body, and is annealed and processed into an electrode to obtain an electrothermal film product. The invention further discloses a heating method of the device. The heating device has the beneficial effects that the heating device is not easy to fall off; the upper temperature limit of the electrothermal film is improved; the heating base body rapidly heats; the highest surface working temperature can reach 800-1,000 DEG C; the highest power density can reach 40W / cm<2>; and the service life is greater than 30,000 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 and a side. 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 electric h...
