    • There are provided a cooling device and a heat sink that can effectively radiate heat generated by a heat source while reducing the volume of discharged gas to avoid noise, and an electronic apparatus in which the cooling device and the heat sink are mounted. A heat sink 3 includes cutouts 24a and 24b through which air serving as gas can be taken in from the outside and which are provided on a side where air discharged from first and second nozzles 6 and 7 serving as openings of a jet generating mechanism 2 is received. Therefore, the pressure near the cutouts is decreased by air flow discharged from the first and second nozzles 6 and 7, and outside air is taken in through the cutouts 24a and 24b. Consequently, more gas than gas discharged from the first and second nozzles 6 and 7 is discharged from an outlet of the heat sink. This can minimize the volume of jetted gas to avoid noise, and effectively radiate heat generated by a heat source.
    • 提供了一种冷却装置和散热器,其能够有效地辐射由热源产生的热量,同时减少排出的气体的体积以避免噪音;以及电子设备,其中安装有冷却装置和散热器。 散热器3包括切口24a和24b,通过该切口24a和24b,可以从外部吸入用作气体的空气,并且设置在从用作喷气发生机构2的开口的第一和第二喷嘴6和7排出的空气的一侧 收到了 因此,通过从第一和第二喷嘴6和7排出的空气流,切口附近的压力减小,并且外部空气通过切口24a和24b被吸入。 因此,比从第一和第二喷嘴6和7排出的气体多的气体从散热器的出口排出。 这样可以最大程度地减少喷射气体的体积,以避免噪音,并有效地辐射热源产生的热量。
