Title:
気体噴出装置
Document Type and Number:
Japanese Patent JP4572548
Kind Code:
B2
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 (1) according to the present invention includes a vibrator (25) 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 (23) and (24) to deaden out each other. Also, a control section (20) optimizes the frequency of the vibrator (25), hence, by increasing the gas ejection quantity as much as possible while inhibiting noise generation, heat of a heater is effectively dissipated.
