This paper describes results from an experimental study of the effect of an Electro hydro dynamics (EHD) and electro static force on the critical heat flux (CHF) in pool boiling at atmospheric pressure. HFE-7100(3M), which is a electrically isolated liquid and has a boiling point of 59.8 -C, was selected as a working fluid. In order to generate high electric fileds with the application of low voltages, a micro scale electrode which was interdigitated with a emitter and a collector with a space of 100 gm was made by microfabrication technology. The electrode had ten slits whose width was 400pm between electrode pairs so as to remove vapor bubbles from a heat transfer surface by the electro static force. A cooling device fabricated with the electrode was evaluated by different electric fields. As a result, the CHF was increased with the application of voltages.
