Abstract: A fan of a heat sink comprising a hub, a plurality of ribs and a set of blades is provided. A distal end of the ribs is connected to circular sidewall of the hub and the set of blades are connected to the primal end of the ribs. The set of blades comprises an outer ring, multiple first blades, a guiding ring connected to the inner side of the first blades and multiple second blades positioned at the inner side of the first blades extending upwards from the top side of the guiding ring. The primal end of the ribs is connected to the guiding ring having an inclined slope extending from the hub towards the outer ring. The first and the second blades are adopted for increasing the air flow area, and thereby increase the air volume and air pressure and the inclined slope of the guiding ring is adopted to smoothly change the flow direction of the sucked air and thereby reduce the resistance to the air flow.

Abstract: A heat sink comprising an open frame including air inlets on a top side and a rotatable fan having a plurality of blades is provided. The heat sink is installed in the frame. The frame has pluralities of supporting elements and ribs positioned between two adjacent supporting elements. The supporting elements and ribs correspond to each other to form multiple side air inlets. The operation of the fan is capable of drawing a large volume of the air into the open frame via the top side and side air inlets. The flange of the blades is parallel to the inner curved side of the ribs when the blades pass by the ribs so that a large volume of air is guided into the frame to enhance the heat dissipation effect. This may also maintain an optimum static pressure and substantially reduce the noise level during the operation of the fan.
Abstract translation: 提供一种散热器，其包括具有顶侧的空气入口的开放框架和具有多个叶片的可旋转风扇。 散热器安装在框架中。 框架具有位于两个相邻的支撑元件之间的多个支撑元件和肋。 支撑元件和肋条彼此对应以形成多个侧面空气入口。 风扇的操作能够通过顶侧和侧面空气入口将大量的空气吸入开口框架。 当叶片通过肋时，叶片的凸缘平行于肋的内弯曲侧，使得大体积的空气被引导到框架中以增强散热效果。 这也可以保持最佳的静态压力并且在风扇运行期间显着降低噪声水平。

Abstract: A fan impeller of a heat-dissipating fan device is mounted in a receiving space of a fan housing, and includes coupling ribs that extend radially and outwardly from an outer surrounding surface of a hub cap and that are spaced apart angularly from each other, a smaller-diameter first connecting ring disposed coaxially around an intermediate portion of the hub cap and connected to the coupling ribs, a larger-diameter second connecting ring disposed coaxially around a lower portion of the hub cap, and fan blades that are spaced apart angularly from each other. Each fan blade has a first blade body connected to and disposed uprightly on the first connecting ring, and a second blade body connected to and extending radially from the first blade body and having a bottom end connected to the second connecting ring.
