Abstract
A media content receiving device, such as a set top box, includes a chassis that incorporates a heat bridge, a heat shield or both. The heat bridge may take the form of a structural wall coupled to, but preferably integrated with, the chassis to facilitate conductive heat transfer into a chassis panel. The heat bridge may be configured to receive heat radiated from a chip having a die to be cooled. The heat shield may take the form of a wall-type structure protruding from a chassis panel. For example, the heat shield may extend from a top panel of the chassis in a fin-like or flange-like manner to provide a thermal barrier between adjacent electrical components arranged on a circuit board. While the heat shield protects the adjacent component from potential thermal damage or degradation, it may also operate to transfer heat into the chassis.
