Embodiment Construction

[0051] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0052] figure 1 is a perspective view of a gas injector according to one embodiment of the present invention, figure 2 is a cross-sectional cutaway view of the gas injector.

[0053] The gas injector 1 comprises a separate housing 22 . A vibrator 25 is provided in the housing 22, and the inside of the housing 22 is divided into two chambers 22a and 22b by the vibrator 25. As shown in FIG. Chambers 22a and 22b contain, for example, air. A plurality of opening portions 22c and 22d are formed in the housing 22 so as to allow the above-mentioned divided chambers 22a and 22b to communicate with the outside of the housing 22, respectively. In this case, the numbers of the opening portions 22c and 22d are the same as each other. The number of opening portions 22c (22d) may be single. The nozzles 23 and 24 are respectively provided on the opening portions 22c and 2...

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.

Description

technical field [0001] The present invention relates to a gas injector for injecting gas to dissipate heat generated by a heater, an electronic device equipped with the gas injector, and a gas injection method. Background technique [0002] As the performance of PCs (Personal Computers) increases, an increase in heat generated by heaters such as ICs (Integrated Circuits) poses a problem, and various heat dissipation methods have been proposed or commercialized. One method of heat dissipation is by placing a heat sink made of metal such as aluminum in contact with the IC so that heat is transferred from the IC to the heat sink to dissipate heat, and another method is to use a fan to move heat from inside a case such as a PC. The hot air is forcibly dissipated, and the cold indoor air is guided around the heater, thereby achieving heat dissipation. Another method is to use a heat sink and a fan at the same time, and the fan will force the hot air around the heat sink to dissi...
