In this work, the tactile temperature of home theater systems under natural convection conditions has been investigated through numerical approaches and experiment. The CFD analysis method was used to observe temperature changes of both the case top and the heat source. Based on numerical simulation results, four types of steel sheet mock-up having different vent sizes and locations were tested. As a consequence of the experiments, relationships in temperature variation between the case top and the heat source were investigated and verified. In addition, by using the validated and improved vent system, a fanless home theater system was proposed under high heat dissipating heat sources.
