Electrode heater and application thereof

The invention provides an electrode heater and the application of the electrode heater and relates to the technical field of heating devices. The electrode heater comprises a shell and a partition plate. The partition plate is located in the shell and divides the shell into a sealed heating cavity and a sealed control cavity. The heating cavity is vacuum and filled with a heat-conducting medium. The heating cavity is further provided with a plurality of electrodes. The electrodes are dipped into the heat-conducting medium. The heat-conducting medium is heated through electrifying the electrodes. The defects that a traditional resistance wire is prone to fusing and short circuit and shorter in service life under a high-temperature condition are overcome. Meanwhile, superconductive liquid ora mixture of the superconductive liquid and water is used as the heat conducting medium, the phase-transition temperature is low, the heat transfer speed is rapid, a good heat conducting effect is achieved, the heat-conducti
