Bidirectionally-heating electrothermal-film heating tube

Abstract

Disclosed is a bidirectionally-heating electrothermal-film heating tube, and a base material adopted by the nonmetal electrothermal-film heating tube includes, but not limited to a quartz glass tube, a QSC silicon tube and a ceramic tube. The nonmetal electrothermal-film heating tube includes an O-shaped sealing tube plug, an O-shaped sealing ring, an elastic electrode clamp and an electrode lead-out piece. The nonmetal-base-material electrothermal-film heating tube is a nonmetal tube with two through heads and is provided with an outer coating-layer heating tube and an inner coating-layer heating tube and forms a bidirectionlly-heating composite nonmetal nonmetal electrothermal-film heating tube together with the O-shaped sealing tube plug, the O-shaped sealing ring, the elastic electrode clamp and the electrode lead-out piece.

Description

Technical field: [0001] The invention relates to an electric heating film heating tube, in particular to an electric heating film heating tube with bidirectional heating. Background technique: [0002] At present, the known coatings of electrothermal film heating tubes made of non-metallic substrates on the market are all coated on the outside of the tube walls of various non-metallic substrates, and the liquid to be heated passes through the tube walls. The flow of the tube wall and the electrothermal film heating body outside the tube wall do "heat" exchange to obtain the required temperature. Among them, it is applied to the instant electric shower made of "non-metallic electric heating film tube". Since the electric heating film heating tube only adopts one-way heat exchange during use, a large amount of radiant heat energy is wasted in vain. , especially during full power usage. Invention content: [0003] In order to overcome the disadvantages of high power consump...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing non-metallic electric heating film tube with outer coating, the instant electric shower made of large power consumption and large waste of radiation energy

The invention provides a two-way heating electric heating film heating tube, which can effectively solve the problem of the existing one-way non-metallic electric heating film heating tube, and the instant electric shower made of high power consumption and one-way switching. Disadvantages of waste of energy due to insufficient heat exchange with water

Therefore, the present invention will be able to effectively solve the problems of high electric power consumption, low energy efficiency ratio of the above-mentioned existing instant electric heaters, limited by user's power consumption conditions, and difficult promotion.
