Elimination Of Seal In Compressor And Use Of Leakage Flow For Bearing Cooling

Defensive Publications Series

Labyrinth seals play a crucial role in shaft sealing applications in protecting bearings and preventing contamination. However, they tend to have high leakage values which negatively impact compressor efficiency. This proposed solution eliminates the seal and makes the clearance between thrust collar and seal plate big enough to have a controlled leakage. The leakage is used to cool the bearings.

Uniform And Quick Heat Transfer Between High Power Section To Low Power Section Of A Hardened Outdoor Conduction Cooled Chassis, Anonymous

Defensive Publications Series

This disclosure relates to an improved conduction‐cooled enclosure for outdoor networking and electronics systems. Traditional designs often place high‐power components (e.g., switch ASICs, processors) in a “base” section and power supply units in a “lid” section, leading to significant thermal imbalances and potential chassis deformation over time. To resolve these issues, a novel approach adds a Graphite‐over‐Foam (GoF) thermal gasket along the entire mating interface between the base and lid. This gasket works alongside the existing rubber gasket for hermetic sealing and the electrically conductive gasket for EMI/EMC compliance. By providing a dedicated high‐conductivity path (on the order of 3 …
