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 motor includes a shaft, a shell, a sleeve, an abrasion-resistance piece, a bearing, an oil seal, and several compressed springs. The shaft has an axial line. The shell is connected to the shaft. The sleeve has an accommodating space, and the wall of the accommodating space forms a first inclined surface which is inclined at an angle with respect to the axial line. The abrasion-resistance piece is disposed at the bottom of the accommodating space. The bearing is disposed in the accommodating space, and the outer wall of the bearing forms a second inclined surface corresponding to the first inclined surface. The shaft passes through the bearing and abuts the abrasion-resistance piece. The oil seal is affixed to the wall of the accommodating space and covers the bearing. The compressed springs are connected between the oil seal and the bearing.

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.

Abstract: A fan includes a hub and a plurality of fan blades. The hub has an axle center. The fan blades are disposed around the hub. Each of the fan blades has a bent portion, and the bent portions of the fan blades are extended along a surrounding direction surrounding the axle center. The hub is welded with the bent portion of each of the fan blades along the surrounding direction. As a result, the number of fan blades is maximized, the strength is simultaneously ensured to be enough, and the advantages of effectively enhancing the fan characteristics are achieved.

Abstract: A fan includes a hub and a blade assembly. The hub has a central portion and an extension portion. The extension portion is extended outwardly from a peripheral edge of the central portion. The blade assembly includes a plurality of blades. Each blade has a leading edge, each of the leading edges is an end point of each blade that is most close to the central portion. The blades are disposed around the hub. At least a part of the leading edges of the blades are connected to the extension portion, and distances between a center of the central portion and the leading edges of at least two blades are different. Therefore, the factors of fan and the quality of voice could be enhanced, and the multi-frequencies noise could be avoided during operation.
