Abstract
Disclosed is a composite heat-dissipating system and its used fan guard which can impart a supercharging function to the heat-dissipating fans of the composite heat-dissipating system for efficient heat dissipation and reduces the noise generated when the heat-dissipating fans are operated. The fan guard includes a frame and a set of guard blades arranged inside and fixed onto an inner surface of the frame. The fan guard can be arranged upstream or downstream of the rotor blades of the heat-dissipating fans and assembled with the heat-dissipating fans in series or in parallel to supercharge the airflow out of the heat-dissipating fans.
Claims17
A fan guard adapted to be used with at least one heat-dissipating device with a plurality of rotor blades for supercharging an airflow discharging from said heat-dissipating device, comprising:
- a frame;
- and
- a set of guard blades arranged inside said frame, wherein said guard blades are arranged relative to said rotor blades to supercharge an airflow out of said heat-dissipating device;
- wherein said fan guard is disposed on a system frame in which said heat-dissipating device is disposed, and said fan guard is integrally formed with said system frame.
A composite heat-dissipating system comprising:
- at least one fan guard respectively having a frame and a set of guard blades arranged inside said frame;
- and
- at least one heat-dissipating device respectively having a main frame, a plurality of ribs, and a first rotor device with a plurality of rotor blades, wherein the first rotor device is surrounded by the main frame, and the ribs are radially arranged and mounted within said main frame;
- wherein said guard blades are arranged relative to said rotor blades of said at least one heat-dissipating device to supercharge an airflow out of said at least one heat-dissipating device.
A composite heat-dissipating system comprising:
- at least one fan guard respectively having a frame and a see of guard blades arranged inside said frame;
- and
- at least one heat-dissipating device respectively having a first rotor device with a plurality of rotor blades;
- wherein said guard blades are arranged relative to said rotor blades of said at least one heat-dissipating device to supercharge an airflow out of said at least one heat-dissipating device, and said at least one fan guard and said at least one heat-dissipating device are connected in series.
