With the advent of AI technology, cloud computing power has been enhanced in edge computing used in personal devices such as laptop computers. To meet the computational demands, the performance of laptop computers has been improved. However, the improved performance leads tothe heat generation of the central processing unit (CPU) and graphicalprocessing unit (GPU). The limited size of the laptop computerlimitsthe efficiency of its cooling system, which affects its stability and lifespan. Therefore, it is necessary to develop an optimized cooling system for the laptop computer using high thermally conductive materials for efficient heat transfer. The cooling area and fan speeds must be increased, and the air duct needstobe designed to increase airflow rates. Fan type and speedmustbe selected considering cooling effects. Appropriate heat pipes and radiators are also necessary to dissipate heat to the outside of the laptop computer. In this study, we developed an optimal coolingsolutionto improve the cooling efficiency of a laptop computer and compared it with existing ones. We adopted the finite volume method for the simulation, verification, and optimization of the developed solution. At ambient temperatures of 25, 30, and 35°C, the fan speeds were adjusted to 2800, 3200, and 4000 RPM to maintain the temperatures of the CPU at 67.4, 67.3, and 67.1°C, respectively.
