195 results about "Hybrid heat" patented technology

A hybrid heat system reacts to changing temperatures and automatically adjusts to the most efficient energy saving method available to heat or cool a home. It can be a fuel-saving alternative to traditional heating and cooling systems in that it combines a furnace with a heat pump, rather than an air conditioner.

The hybrid core is comprised of a plurality of parting sheets and interposed by a plurality of high thermal conductivity, light weight bridging elements and enclosure bars. These core members are comprised of dissimilar materials. The parting sheets and bridging elements are interconnected by a specially tailored joint which forms form a substantially strong, high thermal conductivity bond. In particular embodiments, carbon-based bridging elements are bonded to metallic parting sheets using a brazed joint. The parting sheets, in certain embodiments, may comprise titanium or Ni-based superalloys or carbon composites, while the carbon-based bridging elements may comprise fiber-reinforced composites. The carbon-based bridging elements reduce the core weight and increase the core thermal conductivity over conventional all-metal designs, while the brazed joint provides for improved leak resistance over all-composite designs.

RF power amplifier assembly with heat pipe enhanced pallet

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.
