AI Technical Summary
Existing electric heating tubes have problems such as poor thermal conductivity of magnesium oxide insulation layer, difficulty in achieving both insulation and thermal conductivity, small heat transfer area of electric heating wire, and excessive temperature difference between electric heating wire and heated medium.
Insulating fluid is used instead of magnesium oxide powder as the insulating medium, and conductive fluid is used instead of electric heating wire as the heating medium. Conductive fluid channels are set inside the insulating column, and insulating fluid channels are set inside the outer shell to achieve liquid insulation and liquid heat conduction, thereby increasing the heating area and uniform temperature.
It increases the surface heat load and operating voltage of the electric heater, reduces costs, improves temperature uniformity, enhances electric heating efficiency and lifespan, and reduces system structural complexity and cost.
