A recently granted patent (Publication Number: US11818872B2) discloses an electrical device with buoyancy-enhanced cooling. The device includes a housing with one or more fins extending away from it, with at least one fin having a partially hollow interior. A cover plate separates the fin interior and the housing interior, with openings connecting them. An electrical component within the housing heats the air inside, and the design of the housing, fins, and cover plate directs the heated air through the fins using buoyancy forces.

Furthermore, the patent details variations in the design, such as the positioning of openings, the use of different types of fins like hollow pin fins or corrugated heat sink fins, and the configuration of ducts within the housing to facilitate airflow. The device is particularly suited for applications like rectifiers, where heat dissipation is crucial for optimal performance. The innovative design allows for efficient cooling of the electrical components by utilizing natural buoyancy forces to circulate the heated air through the fins, ensuring effective thermal management within the device.
