Abstract

The invention discloses an electric heater which comprises an electric heating pipe and a sleeve; the electric heating pipe comprises a quartz pipe and an end seal; an electric heating film is attached to the inner wall of the quartz pipe; the end seal is connected to the end of the quartz pipe in a sleeving mode; the sleeve is provided with a water inlet, a heating cavity, a detection cavity anda water outlet which communicate sequentially; the sleeve is provided with a mounting opening communicating with the heating cavity; the quartz pipe extends into the heating cavity and the end seal tobe fixed to the heating cavity in an airtight mode through the mounting opening; a water inlet valve is arranged at the water inlet; the sleeve is provided with an electrically controlled assembly extending into the detection cavity; and the water inlet valve and the electric heating pipe are electrically connected with the electrically controlled assembly. According to the electric heater, through the mode that a fluid passes through the heating cavity to be circularly heated around the electric heating pipe, heating is even, the heat exchange efficiency is effectively improved, and the danger caused by explosion of the electric heating pipe is effectively prevented.

Description

technical field [0001] The invention relates to a heating device, in particular to an electric heater. Background technique [0002] The electrothermal film heating tube is a heating device that supports a layer of semiconductor film on an insulating carrier such as quartz. It uses quartz glass as a heat-conducting medium and insulating medium, and there is no contact with the liquid to be heated, such as electricity or ions. Avoid the heating conductor in the traditional metal conductor heating process from being eroded, deformed, scaled, etc. by the fluid to be heated, and have a longer service life and very low maintenance costs in the later period. [0003] The above reasons make the electrothermal film heating tube have a very high advantage in the heating of continuous fluid. However, due to the quartz material of the electric heating tube and the uneven heating during the heating process, the life of the quartz will also be affected. Contents of the invention [0...
