Latest Patents

Sakamoto's latest patents include a heat exchanger and a thermoacoustic device that utilizes a unique stack configuration. The first patent describes a thermoacoustic device designed to enhance heat exchange efficiency. This device features a first stack composed of stack constituent elements L and H, which are laminated together. It includes a first high-temperature side heat exchanger and a first low-temperature side heat exchanger at both ends of the stack. A self-excited acoustic wave is generated by the temperature difference between these heat exchangers, converting thermal energy within the stack. The configuration of stack constituent elements with varying thermal conductivities optimizes the device's performance.

Another notable patent is a thermoacoustic device with a suppressor. This device incorporates a loop tube with a first stack positioned between a first high-temperature side heat exchanger and a first low-temperature side heat exchanger. A second stack is also included, preventing heat from being transported between the two stacks, even when large acoustic waves are generated. The device utilizes self-excited standing and traveling waves to cool the second low-temperature side heat exchanger, enhancing its efficiency.
