Research on Local Heating of Flat Plate Based on Electric Field Distribution Regulation

At present, heating the local fixed point area of the plate is a research hotspot. This paper introduces a local heating method of the plate based on electric field. The electric field regulates the formation of liquid polymer column, and heat transfer from the bottom substrate electrode to the top electrode plate in contact with the liquid polymer column to realize local heat transfer, and the heat transfer position can be accurately regulated by designing several independent conductive areas of upper electrode. The relationship between the center temperature of liquid column and time is studied. It reaches the highest temperature of 100.7 ℃ when the preset temperature of the heating platform was 135℃.
