Abstract: An impeller includes a hub, an outer ring, a plurality of first blades and a plurality of second blades. The plurality of first blades are arranged around the hub at intervals. Each of the plurality of first blades passes through the outer ring, extends inward from the outer ring, and is connected to the hub. The plurality of second blades are arranged around the hub at intervals. Each of the plurality of second blades passes through the outer ring. At least one of the plurality of second blades is disposed between the plurality of first blades. A length of each of the plurality of second blades is between 10% and 45% of a length of each of the plurality of first blades.

Abstract: A centrifugal fan is disclosed and includes a housing, a fan wheel, a first throat portion and a second throat portion. The housing includes a lower cover connected to an upper cover through a peripheral wall to form an accommodation space and an outlet. The upper cover includes an inlet communicated with the outlet. The fan wheel is disposed on the lower cover and accommodated in the accommodation space. The fan wheel is rotated along a rotation direction. The first throat portion is disposed adjacent to a lateral end of the outlet and protrudes from the peripheral wall toward the accommodation space. The second throat portion is disposed adjacent to another lateral end of the outlet, and protrudes from the peripheral wall toward the accommodation space. When the fan wheel is rotated along the rotational direction, an airflow is guided from the first throat portion to the second throat portion.

Abstract: A heat dissipation assembly is disclosed and includes a fan, a vapor chamber and a heat dissipation fin set. The fan includes a fan frame, an impeller and a fan cover. The impeller is disposed on the fan frame and accommodated in an accommodation space. The impeller includes plural metal blades and a hub, and the plural metal blades are radially arranged on the periphery of the hub to form a dense-metal-blade impeller. The fan cover is assembled with the fan frame to form an outlet, and the fan cover includes an inlet. The vapor chamber includes an upper plate and a lower plate assembled with each other. The upper plate or the lower plate is connected to the fan cover, and the vapor chamber and the fan cover are coplanar. The heat dissipation fin set is connected to the lower plate and spatially corresponding to the outlet.
