Latest Patents
Natsuo Arai holds a patent for a "Method for sealing liquid coolant into module." This invention involves a module placed inside a hermetically sealable chamber. The module consists of a substrate that incorporates multiple electronic circuit parts, a frame that encloses these parts, and a cover that protects the opening of the frame. The process begins by reducing the pressure in the chamber to a first pressure P1, followed by an increase to a second pressure P2. Liquid coolant is then introduced into the module through a hole in the cover, and the chamber pressure is raised to a third pressure P3. Finally, the hole is sealed, ensuring the liquid is securely contained within the module. The chamber pressure is then returned to atmospheric pressure P0, allowing the module to be safely removed.
