Embodiment Construction

[0127] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0128] FIG. 1 is a perspective view of a jet generating device according to one embodiment of the present invention. Fig. 2 is a cross-sectional view of the jet flow generating device.

[0129] A jet generator 1 has, for example, two separate housings 11 and 12 . Housings 11 and 12 have vibration mechanisms 5 and 6, respectively. The vibration mechanisms 5 and 6 have vibration plates 7 and 8, respectively. The vibrating plates 7 and 8 are made of a soft film material such as PET (polyethylene terephthalate) film material or the like. Both vibration mechanisms 5 and 6 have structures such as speakers. The vibration mechanisms 5 and 6 are each constituted by coils, magnets, etc. (not shown). Vibration plates 7 and 8 are asymmetrical with respect to their vibration directions.

[0130] The housings 11 and 12 form chambers 11a and 12a, respectively. Bo...

Abstract

A jet flow generating apparatus that suppresses noise as much as possible and effectively radiates the heat generated by a heat generating member, an electronic device that is equipped with the jet flow generating apparatus, and a jet flow generating method are provided. According to the present invention, a jet flow generating apparatus comprises a plurality of chambers each having an opening and each containing a coolant, a vibrating mechanism for vibrating the coolant contained in each of the plurality of chambers so as to discharge the coolant as a pulsating flow through the openings, and a control unit for controlling the vibration of the vibrating mechanism so that the sound waves generated by the coolant discharged from the plurality of chambers weaken each other.

Description

technical field [0001] The present invention relates to a jet generating device for generating a jet and using the generated jet to cool a heating element such as an electronic part, an electronic component equipped with the jet generating device, and a jet generating method. Background technique [0002] As the performance of PCs (personal computers) improves, the heat generation rate of heating elements such as ICs (integrated circuits) rises sharply. In order to solve such problems, various heat dissipation techniques have been proposed and / or actually applied. As one of the heat dissipation methods, heat dissipation fins made of, for example, aluminum metal are attached to the IC, and the heat generated by the IC is transferred to the fins to dissipate heat. In addition, there is a method in which hot air remaining in the PC case can be forcibly exhausted by a fan, and cool air surrounding the PC is forcibly introduced around the heating element by using the fan. In ad...
