US 8,619,427 B2 · Media content device chassis with internal extension members

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.

Dependent claims

A system comprising:

a thermally conductive chassis having at least one panel with internal and external surfaces, and wherein the external surface is exposed to an environment having an environment temperature that is lower than an internal chassis temperature;
a circuit board located within the chassis;
at least one integrated circuit chip having a die, the chip positioned on the circuit board, the die operable to radiate an amount of thermal energy;
an electronic component positioned on the circuit board within a vicinity of the chip;
and
a heat shield coupled to the chassis, the heat shield configured to protrude from the internal surface by an amount that sufficiently shields the electronic component from radiated thermal energy generated by the die.
