With development and advancement of notebook, at the same time it brings its cooling problem, it is very important that use outside surface cooling except inside. The main in study is simulate of electronic cooling in Notebook outside surface, design force convection models and placed them under the Notebook, force convection has immediate effect on the surface and produce heat dissipation. The simulation uses software FLUENT 6.0 to analysis the result of heat dissipation, the models are constructed and described by use turbulent field of three dimensions. The study has two main parameters¡GThe form of force convection models and controlled airflow. The result of numerical analysis use Nusselt number to determine the effect of heat dissipation. According to the result of numerical analysis to increase effect of heat dissipation for the following methods¡G1. Increase airflow across the designed models, 2. Decrease the angle of elevation when using notebook, 3. Airflow enter the designed models by one entrance and leave by the side exports, 4. When airflow pass through the designed models smoothly, 5. Airflow can influence the notebook surface immediately.
