Abstract: An impeller is provided, including a metal housing, a shaft, and a plastic member. The metal housing has a shaft mounting hole. The inner surface of the shaft mounting hole includes three or more contact points, and the contact points are closer to the shaft than other portions of the inner surface of the shaft mounting hole. The shaft passes through the shaft mounting hole and is affixed by the contact points. The metal housing divides the shaft into an upper section, a middle section, and a lower section. The plastic member passes through the shaft mounting hole and is in contact with the middle section.

Abstract: The disclosure relates to an asymmetrical double-outlet blower, including an upper case, a lower case and an impeller. The upper case includes an inlet. The lower case and the upper case are assembled to form a housing having an accommodation space, and form a first outlet and a second outlet. The accommodation space is in fluid communication with the first outlet, the second outlet and the inlet. The first outlet and the second outlet are disposed on a lateral periphery of the housing and face two opposite directions, respectively. An opening cross-sectional area of the first outlet is less than an opening cross-sectional area of the second outlet. The impeller is accommodated within the accommodation space of the housing, spatially corresponding to the inlet, and rotated around a rotation axis. An airflow is inhaled through the inlet and transported to the first outlet and the second outlet, respectively.

Abstract: A centrifugal fan is provided and includes an impeller, a motor, a first case and a second case. The motor is connected with the impeller to drive the impeller to rotate. The first case and the second case are assembled to form an accommodation space for accommodating the impeller and the motor. The first case includes a first side, a first guiding wall, a flow inlet and a flow outlet. The flow inlet is disposed on the first side, the first guiding wall is connected with the first side, and the flow outlet and the flow inlet are located at a same side of the centrifugal fan. The second case includes a second side and a second guiding wall connected with the second side. The first guiding wall and the second guiding wall are assembled to form a flow guiding channel, which has cross-sectional areas with different sizes.

Abstract: A fan includes a base, a motor and an impeller, and the motor includes a sleeve, a rotor, a position limiting element and a composite elastic element. The sleeve is disposed on the base, and the sleeve has a bottom portion and a side wall, which constitute an accommodation space. The rotor has a rotating shaft disposed within the accommodation space, and the rotating shaft has an outer wall. An annular groove is formed on the outer wall and has a surface. The position limiting element is disposed on the sleeve and extended from the side wall toward the rotating shaft, and the position limiting element has a bottom surface. The bottom surface faces toward the bottom portion, and the bottom surface is interfered with the surface, thereby eliminating the gap between the bottom surface and the surface. Therefore, noise of the up and down vibration is avoided from generating.

Abstract: A heat dissipation assembly is disclosed and includes a frame and a fan. The frame includes a heat conduction channel and an airflow intake. The heat conduction channel is communication with an exterior through airflow intake. The frame includes a first plane, a second plane and an inclined plane. The first plane is disposed adjacent to the airflow intake. The inclined plane is connected between the first plane and the second plane. The second plane includes an inlet. The heat conduction channel is in communication between the airflow intake and the inlet. A cross-section area of the heat conduction channel adjacent to the airflow intake is greater than that of the heat conduction channel adjacent to the inlet. The fan is spatially corresponding to the inlet, and assembled with the frame to form an outlet in communication with the airflow intake and the heat conduction channel through the inlet.
