“…Thermal management is important in many sectors [8][9][10][11][12], such as the electronics industry [13][14][15][16][17][18][19], has become a development bottleneck. Many conclusions about thermal management are focused and attributed to the increased residual heat produced by Information Technology Equipment (ITE), which include devices that have a primary function related to the collection, transfer, storage, or processing of data [20].…”

This work presents a design and model of the thermo-hydrodynamic behavior applying CFD for pin-fin heat sink with square shape (rectangular fin profile), through a novel pin arrangement that improves heat removal in the system. The novelty consist in the insertion of a deflector row that will help to direct the flow, so it hits the rectangular cross-sectional fins the presents in the system. The heat sink model is placed in channel designed in which air flows as suitable medium, and its overall performance is investigated. In addition, a constant heat flux is applied to the bottom wall of the heat sink model, equal values and amounts that correspond to the heat fluxes generated by current electronic equipment and devices. The numerical results of the global thermal resistance, the pressure drop and the Nusselt number are reported. The results allow determining best arrangement or geometry configuration, location and functionality of the fin-deflectors were collocated for evaluate thermal-hydraulic efficiency of system.
