The port for a removable module of a set-top box in a cable television system incorporates guide members of a thermally conductive material to provide a new primary heat dissipation path to manage thermal energy generated by operation of the module. The guide members may also be used to guide the module into proper connection with a module connector which electrically connects the circuit on the module with the circuitry of the set-top box. The guide members may be attached to the chassis of the set-top box or integrally formed in the chassis. Thus, heat from the module is provide directly to the chassis of the set-top box from which it is released by convention into the ambient environment.

Method and apparatus for managing thermal energy emissions of a removable module in a set-top box

A guide member for accommodating a removable module is formed from a thermally conductive material having at least one thermally conductive element to provide a new primary heat dissipation path to manage thermal energy generated by operation of the module. The guide member may also be used to guide the module into proper connection with a module connector which electrically connects the circuit on the module with other circuitry. A plurality of thermally conductive elements, such as spring fingers, ribs and fins, provide additional thermal heat dissipation paths and enhance the rigidity of the guide members.

Method and apparatus for managing thermal energy emissions

If the circuitry for processing television and other data signals conventionally contained in a set-top terminal is incorporated directly into a television set, heat from a removable point-of-deployment module inserted into the television set to connect with that circuitry can be primarily dissipated by providing a guide of a thermally conductive material that is in contact with both the module and the electromagnetic interference shield of the television set. This applies in either a cathode ray tube television set or a flat panel display television set. In a flat panel television set, the interference shield takes the form of a shield bracket, which is also used to support the flat panel display. In either case, heat generated by the module is conducted to the shield or shield bracket and then released by convection. Alternatively, the module can, in either case, be installed in direct physical contact with the shield or shield bracket.
