A centrifugal fan includes a frame and an impeller rotatably disposed in the frame. The frame has an air inlet and an air outlet. The impeller includes a plurality of blades and an upper ring. The upper ring is connected to the blades and is located between the blades and an upper cover of the frame. The upper cover has a first annular groove and a second annular groove. The first annular groove and the second annular groove are provided on an inner surface of the upper cover and are arranged around the air inlet. The upper ring has a first annular projection and a second annular projection. The first annular projection axially extends towards the first annular groove. The second annular projection extends towards the second annular groove and is bent away from the air inlet.

Centrifugal fan

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.

Heat dissipation assembly

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.

Impeller

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.

Asymmetrical double-outlet blower

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.

Fan and motor thereof

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.

A centrifugal fan includes a frame and an impeller. The impeller is disposed within the frame. The impeller includes a hub, a first blade group and a second blade group. The hub includes a center part, an inclined part and a connection part. The first blade group is connected with the connection part of the hub. The second blade group is disposed on the inclined part of the hub. There is a first distance between the second blade group and the first blade group. There is a second distance between the second blade group and the center part of the hub.

Impeller and centrifugal fan with same

A computing device is provided. The computing device includes a first and second housing. The first housing includes a first and second set of electrical connection ports. The first set of electrical connection ports is positioned at a first location and in a first orientation. The second set of electrical connection ports is positioned at a second location and in a second orientation, which is different from the first set of electrical connection ports. The second housing is fixed within the computing device. The first housing is slidable, with respect to the second housing, within the computing device to enable access to the second set of electrical connection ports.
