Abstract
A gas ejector capable of effectively dissipating heat generated from a heater while inhibiting noise generation as little as possible, an electronic device equipped with the gas ejector, and a gas-ejecting method are offered. A gas ejector () according to the present invention includes a vibrator () and ejects gas in a form of a pulsating flow such that vibration of the vibrator allows sound waves respectively generated upon ejection of the gas ejected from nozzles () and () to deaden out each other. Also, a control section () optimizes the frequency of the vibrator (), hence, by increasing the gas ejection quantity as much as possible while inhibiting noise generation, heat of a heater is effectively dissipated.
