Abstract
Laptop’s cooling solution is very important. In some cases, due to poor cooling an over heat on the mother board, main chip, and other components occurs, so that the laptop is quickly broken. Therefore it is necessary to know the temperature distribution so that over heat can be overcome. One of the methods to determine the temperature distribution in this final project is a flow simulation, using CFD (Computational Fluid Dynamics), 3D method with the variation if different air flow velocity, i.e. 5 m/s, 10 m/s, and 15 m/s. The higher the air flow rate, the higher the cooling occurs. From the temperature contours it is shown that the hot temperature is built up on the back of the heat sink. The results of the validation of this study and previous studies obtained an error that occurred was around 4%.Keywords: CFD, variation of air flow velocity, laptop.
Highlights
Nowadays, many developed countries around the world are making technologies that are evolving and modernize
While at outlet because the outlet speed is greater than speed around, there will be heat transfer of convection, so that the temperature at the outlet is lower than the temperature around it
At the power supply temperature distribution is higher than other areas
Summary
Many developed countries around the world are making technologies that are evolving and modernize. The technology is widely used for research about combining free convection heat transfer and heat transfer from radiation. Forced convection is an occurrence where the heat flow is forced with aid of some devices, such as a fan or blower, to flow to destination. Convection heat transfer depends on the viscosity of the fluid's thermal properties. This is understandable since viscosity affects the velocity profile, affecting the rate of energy transfer in the wall area. In the heat transfer process by forced convection, where the flow is induced by several ways that come from fans, pumps, and blowers. This research is doing to see the phenomenon of the effect of cooling and flow characteristics when the velocity varies. The aim of this research is to use CFD software to select the numerical simulation of the cooling on laptop
