Abstract

The invention discloses an energy-saving heating body coated by a novel electrothermal film. The energy-saving heating body comprises a front fixing plate, a rear fixing plate and an electrothermal pipe. The electrothermal pipe comprises a quartz glass tube body, the electrothermal film is deposited on the outer wall of the quartz glass tube body in a vapor phase mode, the electrothermal pipe is connected in series with channels in the front fixing plate and the rear fixing plate to form a waveform through pipe, one end of the through pipe is connected with a water inlet, and the other end of the through pipe is connected with a water outlet. The formula of solutions of the electrothermal film comprises stannic chloride, alcohol, antimony butter, rare earth elements, ferric trichloride, absolute ethyl alcohol, titanium tetrachloride and boric acid. A water groove is formed outside the electrothermal pipe, the water groove is provided with a cold water inlet and a water outlet. The formula of the solutions of the electrothermal film is simple in gradient, convenient to prepare, and good in using performance, and the energy-saving heating body is high in thermal utilization efficiency, saves energy, and is friendly to environment.

Description

[0001] The patent application of the present invention is a divisional application of the invention title "an energy-saving heating body coated with a new type of electrothermal film". The filing date of the original application is August 27, 2013, and the application number is 2013103768808. technical field [0002] The invention relates to an energy-saving heating body coated with a novel electrothermal film. technical background [0003] Traditional water heaters use exposed electric heating wires for heating. With the development of electric heating film technology, water heaters using electric heating film heating tubes for heating also appear in large numbers. For example, the Chinese invention patent with the application number of 200910108880.3 disclosed an electrothermal film and its manufacturing method on March 10, 2010, wherein the electrothermal film treatment liquid is made of tin tetrachloride, titanium tetrachloride, bromine tetrachloride, trichloride Titaniu...

AI Technical Summary

Problems solved by technology

However, the formula of this solution is complex and inconvenient to prepare, and the performance of the sprayed conductive film is not good enough. The instant electric water heater using the electric heating film heating tube generally has a power of more than 6KW, and the electric heating tube heats the cold water entering the pipeline. A large amount of heat is emitted to the outside, which affects the work of other electrical appliances and even poses safety hazards. Usually, an asbestos insulation layer is installed outside the electric heating tube. Asbestos fibers pollute the environment and affect the health of users, and increase the cost. low utilization
