Nucleate boiling is a very efficient way of cooling mechanism in high power density system. Bubble formation in nucleation boiling phenomenon above critical heat flux in micro and nano channels may lead to instability of the flow in one direction and dry out condition. This paper reviews the process for increased nucleate boiling in micro and nano structure for enhanced evaporating cooling. Surface characteristics, wettability, electric field, vibration along with variation of surfactant, pressure and velocity taken into consideration as well. Microstructure plays an important role in enhancement of the nucleate boiling heat transfer mainly by increasing heat transfer area, active nucleation site density and bubble departure frequency. Groove structure on the heating surface has not been prioritized in the past so much more attention is needed in finding the proper structure for increasing the nucleate boiling.
