Abstract
An electronic device is disclosed. The electronic device includes a shield that provides thermal and electromagnetic interference (“EMI”) shielding benefits. The shield is secured with fan assemblies by airtight seals to prevent air leakage and promote a pressured volume when the fan assemblies are running. Further, the shield can direct airflow from the fan assemblies to one or more thermally conductive components, where the airflow can convectively cool the thermally conductive components and exit the electronic device. The shield is made from a metal, and when the shield covers a circuit board, the shield protects an EMI barrier for integrated circuits located on the circuit board. Moreover, the shield can provide a single-piece, monolithic body that provides advantages over multiple shields, such as eliminating gaps in the shield for air leakage and EMI intrusion, increasing air circulation efficiency, and decreasing costs.
