  • Patent number: 7355848
    Abstract: A system and method removes heat from an enclosure or housing of a subscriber optical interface. When a subscriber optical interface housing is attached to a structure such that a partially enclosed volume of space remains between the structure and the subscriber optical interface housing, this partially enclosed volume of space can produce a chimney effect when heat from the subscriber optical interface housing is intended to flow from fins towards the structure. This chimney effect can refer to a fluid such as air within the partially enclosed space that is heated by the fins and that rises upward when the ambient or surrounding fluid is cooler relative to the heated fluid. According to another exemplary embodiment, the subscriber optical interface can be shaped to form an internal chimney structure that is entirely surrounded by a housing of the subscriber optical interface.

  • Patent number: 7342797
    Abstract: A heat sink device for conventional memory modules, such as DIMMs, that is configured to be positioned between adjacent memory modules mounted in substantially parallel connectors on a printed circuit board. Each heat sink device includes thermally conductive first and second members configured to thermally couple with electronic components of a conventional memory module. The first and second members may be resiliently biased away from one another so that the resilient bias causes the members to abut respective electronic components when placed between adjacent memory modules. A separate wedge, or a lever-mounted wedge, may be provided for insertion between the members to urge them away from one another and into abutting relationship with electronic components on facing surfaces of the adjacent memory modules. When abutting opposing electronic components, a single heat sink device facilitates heat dissipation from both of the adjacent memory modules.

  • Patent number: 7342788
    Abstract: An RF amplifier assembly employing a finned heat sink and a heat pipe enhanced aluminum pallet is disclosed. The hybrid heat pipe enhanced aluminum pallet reduces the spreading thermal conduction resistance associated with the conduction of localized energy from RF amplifier devices when compared to a copper pallet. The localized energy concentration of RF amplifier devices is spread along the length of the heat pipe increasing the overall efficiency of the heat sink coupled to the pallet and accommodating non-uniform heat loading. This reduces the junction temperature of the devices, which leads to higher mean time before failure and higher output levels. The pipes are formed and embedded into the pallet so as to pass under different areas of interest and extend to the under-utilized regions.

  • Publication number: 20080055864
    Abstract: There is described a module for an automation device with a plurality of adjacent modules, having a housing capsule that has at least one rear wall and two side walls and which is provided for housing electric components. There is also described an automation device having modules of said type. It is proposed that one of the side walls of the modules be embodied as being thermally conductive and that the other side wall be embodied as being thermally insulated. That will on the one hand result in improved heat dissipation for the modules and, on the other, will prevent the thermal coupling of adjacent modules of the automation device.

  • Patent number: 7333339
    Abstract: A heat dissipation system for a miniaturized form factor card allows a communications system for mobile information devices contained in the card to operate with high heat loads by employing a high conductivity pad on the printed circuit board of the mobile information device which contacts the case of the miniaturized form factor card. Additionally, heat dissipation plugs are integrated into the edge of the PCB with emitting surfaces adjacent radiation holes in the case of the mobile information device adjacent the PCB. Heat convection channels through layers of the PCB allow transfer of heat from the pad to other conductive layers in the PCB. High thermal conductivity packing in the miniaturized form factor card conducts heat from the internal components to the case of the card in contact with the high conductivity. Placement of high heat generation components within the card case adjacent the contact interface with the high conductivity pad is also employed for maximum heat dissipation.
