Enhanced Micro Channel Heat Sink for Utilization in Cooling Of Electronic Components by Using CFD Approach

The micro-channel heat sinks (MCHS) are used in sophisticated cooling systems to meet the cooling requirements of electronic equipment fitted with high-performance integrated circuits, such as computer chips. In order to increase the effectiveness of heat exchange in MCHS, various types of micro-channel designs have been created. In this study, a three-dimensional micro-channel heat sink has dimensions of 18mm6.2mm0.5mm. the effective use of boehmite aluminium nanoparticles with the base fluids, water, ethylene glycol, etc. The micro channel heat sink includes numerical analyses of several MCHS designs with thermohydraulic efficacy. Throughout the micro channel heat sink, various MCHS designs are analyzed numerically. The Navier-Stokes solution and the energy equation are solved using the finite-volume method, and the hemodynamic and heat efficiencies of the micro channel heat sink is calculated. The results show that the MCHS's triangular design has the maximum heat transfer coefficient, and while its rectangular shape has the lowest heat transmission value. When the velocity is altered, the mean bottom surface temperature for both MCHS shapes decreases, increasing efficiency. The triangle shape of the MCHS establishes the lowest temperature. The triangle shape of the MCHS results in the highest pressure drops, whereas the rectangle shape results in the lowest pressure drops. MCHS has a low thermal resistance due to its triangle shape, but it has a high thermal resistance because to its rectangular shape. The rectangle-shaped MCHS produces the maximum temperature and dissipates the most heat when comparison to the triangle-shaped MCHS. the entire study is carried out by commercially available software ANSYS FLUENT.
