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.

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: An impeller and a fan are provided. The impeller includes a hub, a plurality of first blades, a plurality of second blades and a connecting member. The plurality of first blades are disposed around the hub separately. Each first blade is connected with a periphery of the hub. The plurality of second blades are disposed around the hub separately. Each second blade is disposed away from the periphery of the hub and located between two adjacent first blades of the plurality of first blades. The connecting member is disposed around the hub and penetrated through the plurality of first blades and the plurality of second blades. The connecting member is not in contact with a first edge of any side of each first blade. The connecting member is not in contact with a second edge of any side of each second blade.

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: A fan impeller includes a hub, a shaft, a metal housing and a plurality of blades. The outer periphery of the hub has a curved surface. The shaft is disposed in the hub and connected to the hub. The metal housing has an annular shape and is disposed in the hub. A magnetic ring is disposed at the inner side of the metal housing. The blades are disposed around the outer periphery of the hub. The blades are projected along an extension direction toward the shaft to define projection areas thereof, and the projection area of a top and a bottom of any one of the blades is partially overlapped with other two adjacent blades. A distance between an outer edge of each blade and a rotational axis of the fan decreases proximate the top of the blade and then increases towards the bottom of the blade.

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.
