Document Type and Number:
WIPO Patent Application WO/2018/045830
Kind Code:
A1
Abstract:
A fan system (202) and a server. The fan system (202) comprises a stator body (101), a rotor body (102), fan blades (103), and noise reduction foam (104). The stator body (101) is provided within the rotor body (102) and connected to an external power module (201). The rotor body (102) is securely connected with the fan blades (103). The noise reduction foam (104) is adhered to the outer surface of the rotor body (102). When receiving a drive current inputted by the external power module (201), the stator body (101) drives the rotor body (102) to rotate around the stator body (101) along a designated direction. When rotating around the stator body (101) along the designated direction, the rotor body (102) drives the fan blades (103) to rotate. When rotating under the driving of the rotor body (102), the fan blades (103) drive air to move along the designated direction. The noise reduction foam (104) is adhered to the outer surface of the rotor body (102). At least one blind hole is provided at the side of the noise reduction foam (104) in contact with the outer surface of the rotor body (102). The noise of the fan system (202) is low.
