In this study, thermal analysis for the design of a complex electronic enclosure, Ethernet switch box is designed. The Ethernet Switch in iDEN EBTS (integrated Digital Enhanced Network Enhanced Base Transceiver System) is required for deployment of quad two way BR (Base Radio). Most of the devices in the base case are above the allowable temperature limit without any air vents and heat enhancing devices. Hence suggested to provide heat sink that enhances heat transfer on the critical components and operating well below the allowable temperature. In this paper, the investigations are carried for the improvement of device performance with the help of heat sink and side vents on the enclosure that increases the heat transfer. The complete analysis is carried out with commercial CFD (Computational Fluid Dynamics) software, Fluent V 6.1.22.
