  • Publication number: 20240175797
    Abstract: An acoustic focusing chip is irradiated with ultrasonic waves from an acoustic element P. A flow path having an inlet and an outlet is formed inside of a plate body along a plate surface. A region proximate to the inlet of the flow path of the plate body is set as an ultrasonic wave application region for receiving irradiation of the ultrasonic waves. The acoustic element is arranged on the plate surface in the ultrasonic wave application region. A reflective portion capable of reflecting the ultrasonic waves toward the flow path is formed along the flow path in the ultrasonic wave application region. Thereby, the flow focusing ability, heat dissipation, and strength retention can be cost-effectively improved with a simple configuration.
