摘要：

Heat transfer methods in small scales have been studied widely to enhance the thermal efficiency and performance of heat sinks in the field of cooling electronic devices. In this study, a comprehensive numerical investigation was conducted to evaluate thermal performance of block heat sinks for cooling electronic processors by using Nanofluid. Two different blocks including spiral and serpentine blocks were designed and tested under various working conditions using Nanofluid Fe3O4/ water with a volume concentration of 0.2% and obtained results were compared to water in the term of heat transfer rate and efficiency. As one of the main aims of this study, thermophysical properties of under evaluation nanofluid were analyzed using experimental data and theoretical equation and subsequently obtained heat transfer results for all cases were discussed. ANSYS-Fluent software was utilized as a CFD method to solve the problem and perform analysis from simulation.
