Abstract

Due to the enormous heat fluxes emitted by modern electronic chips, there is a persistent need to enhance the efficiency of cooling systems. This study’s focus is on optimizing heat transfer in micro-channel heat sinks that use liquid cooling. Geometric changes and the use of nano-fluids as coolants in place of water are performed to achieve this goal with little energy consumption. Numerical analysis of pipe micro-channel fluid flow and heat transfer. is presented, along with a systematic and accurate methodology for doing such an analysis provided by this work. This study examines the temperature and velocity of water passing via a little conduit. In addition, the micro-channel within the pipe is discretized using Finite Element Method. Adding domain elements and nodes discretizes finer components. MATLAB codes are designed for this. The simulation results reveal that entrance velocity variations greatly affect fluid flow and temperature research. The temperature fields affect energy sources in the domain’s midsection. The findings show that the fluid flow is upward and that the heat transfer mode is conductive. The investigation examines how adding a heat source to the temperature field changes things. This work supports the concept that our computation matches that of other academics who have studied similar fundamental geometries. FEM is effective for analyzing constant flow due to its simple measuring techniques.
