Embodiment Construction
[0010] The present invention will be further described below in conjunction with accompanying drawing.
[0011] On the outer surface of a tube with different diameters made of high-temperature-resistant glass, according to different heating power requirements, a layer of transparent electrothermal film with different thicknesses is coated by chemical vapor deposition, and electrodes are coated on both ends of the electrothermal film. It is connected with wires, then installed in the required part of the chemical glass practical training and teaching device, and then energized for heating. Using the heating device of the present invention, not only the heating is uniform and the speed is fast, but also the experimental phenomena can be clearly observed.

The invention discloses an energy-saving transparent electrothermal film heating device which comprises a transparent high-temperature-resistant heat conduction tube and a transparent electrothermal film which uniformly covers the surface of the heat conduction tube and is high in heat efficiency and long in service life. Due to the electrothermal film heating mode and the transparent design, the problems that a traditional electric heating wire heating device is high in energy consumption, heating is not uniform and the visual effect is poor when the state of a heated object is observed. The device has the prominent advantages of being simple in structure, saving electricity, and being capable of well meeting the requirements of practical training experiment instrument teaching of glass for chemical equipment buildings.
Description
technical field [0001] The invention relates to the field of liquid heating, in particular to an energy-saving and transparent electrothermal film heating device. technical background [0002] In the traditional electric heating device, the electric heating layer generally uses electric heating wires to be placed on the heated place for heating. This heating method consumes a lot of electric energy and the use cost is high. Especially in the chemical glass training teaching device, because the traditional heating wire heating device used for heating is opaque, it is impossible to directly observe the experimental phenomenon of material heating during the teaching operation, so the teaching effect is greatly reduced. Contents of the invention [0003] The present invention aims to solve the problem that the traditional heating device consumes a lot of energy, uses high costs, and affects the teaching effect when used in chemical glass training and teaching devices, and prop...
