Heat transfer enhancement is one of the most significant fields for optimization of energy consumption. Boiling heat transfer as one of the most important type of heat transfer is used for sensitive electrical devices cooling in addition to various industries like power plants, refineries and chemical industries. Due to phase change phenomena in this type of heat transfer, high flux heat transfer from surface is possible and boiling heat transfer enhancement can be taken into account as a very efficient tool to increase efficiency of systems. One of the most successful methods for enhancement of boiling heat transfer coefficient is using of enhanced surfaces with convenient and regular matrix pattern that makes phase change and nucleate boiling faster and provides high flux heat transfer with low temperature difference by creation of nucleation sites for nucleate boiling. In this work, an experimental setup is designed and built for investigating fluid pool boiling process. Then a convenient pattern is chosen for enhancing surface geometry and finally effects of these changes to enhancement of nucleate boiling heat transfer will be investigated.
