Latest Patents

Aoki’s listed patents address cooling and electrical integration in power conversion equipment.

- **Power converter.** This invention describes a housing containing a wind-tunnel cooling structure with two parallel ducts. Each duct has an inlet, an outlet, a cooling-air path, and a blower fan. The ducts’ inlets and outlets are positioned adjacent to one another, while heat-generating components are divided between the ducts. The arrangement is designed to direct cooling air around components within the converter.

- **Wiring board and power conversion device.** This invention describes a wiring board with a conductor plate that includes a wiring portion and an electrode portion connected to a power-conversion semiconductor element. A liquid-cooling pipe is mounted near the conductor plate, and insulating resin is placed at least between the plate and the pipe. The design combines electrical connections, insulation, and liquid cooling in a power-conversion device.
