Frame of fan

A centrifugal fan includes a housing and an impeller. A top side of the housing has a main air inlet. A bottom side of the housing has a holder, a board, and plural supporting ribs connecting the holder and the board. The holder, the board, and the supporting ribs define a first secondary air inlet and a second secondary air inlet. In the extending direction of the central axis of the impeller, the impeller projects an upper projection to the top side, and projects a lower projection to the bottom side. The size of the upper projection is greater than the size of the main air inlet. At least one portion of the outer edge of the first secondary air inlet, the outer edge of the lower projection and the central axis are arranged in sequence.

Centrifugal fan

A fan module is adapted to be disposed on a mainboard. The fan module includes a base, a stator unit, a circuit board, a first restriction structure and a second restriction structure. The base includes a mounting shaft and a base opening, wherein the mounting shaft has an axis. The mounting shaft is telescoped in the stator unit. The circuit board is coupled to the stator unit, wherein the circuit board includes a circuit board connection port. The first restriction structure restricts the circuit board, wherein the first restriction structure is arranged on the first straight line, and the first restriction structure is disposed a first distance away from the axis. The second restriction structure restricts the circuit board, wherein the second restriction structure is arranged on the second straight line, the second restriction structure is disposed a second distance away from the axis.

Fan module

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.

A fan structure includes a fan impeller, a motor and a fan frame. The motor has a rotating shaft connected to the fan impeller. The fan frame encloses the motor and the fan impeller to form a flow passage. The fan frame has a bottom wall and a side wall. The side wall includes a first relatively hard portion and a first relatively soft portion that is exposed in the flow passage.

Fan structure

An axial fan assembly includes a first axial fan and a second axial fan arranged side by side. The second axial fan includes an impeller having a shaft, and a frame. The frame includes a surrounding wall and a lateral guiding structure. The surrounding wall forms an axial flow channel for accommodating the impeller, wherein the surrounding wall includes a first outer wall surface facing the first axial fan, and an airflow generated by the impeller flows out of the axial flow channel through an outlet end. The lateral guiding structure is protrudently disposed at the outlet end on an edge surface connected with the first outer wall surface, wherein the lateral guiding structure guides a partial airflow of the airflow at the first edge surface toward a first direction, and the first direction and a normal direction of the first outer wall surface include a first acute angle.

Axial fan and axial fan assembly

A fan includes a fan frame and a driving device. The fan frame includes a base, a frame shell and static blades arranged on the periphery of the base. The driving device includes a stator structure and a rotor structure. The stator structure includes a stator magnetic pole group and a bushing. The rotor structure includes a bearing, a shaft, a rotor shell, a magnetic structure, a magnetic shell and blades. The shaft is connected with the rotor shell and disposed through the bearing. The stator magnetic pole group magnetically drives the magnetic structure to rotate the rotor shell. Two ends of the frame shell are configured with two turning portions, respectively. The two turning portions are disposed between parts of the frame shell with different curvatures. A curvature of the first turning portion is larger than a curvature of the second turning portion.

Fan frame

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 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.

Impeller and fan employing same

A fan frame includes a housing, a shaft seat, a curved rib, a plurality of first ribs, and a plurality of second ribs. The shaft seat is disposed at the center of the housing. The curved rib is disposed between the housing and the shaft seat. The first ribs extend through the curved rib and connect the shaft seat to the housing, and the second ribs connect the curved rib to the shaft seat.

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.
