As shown in Figure 2, embodiments provide a kind of fan board, can comprise:
The fuse be connected with outside copper bar, for being fused by the actual output current of described outside copper bar when described fan board fault, to disconnect the connection of described fan board and described outside copper bar, wherein, the actual output current of described outside copper bar is greater than the maximum electrical current of described fuse.
Fuse connection fan board and outside copper bar are to make fan board from outside copper bar power taking; when fan board fault; when making copper bar occur over-current phenomenon avoidance; by blown fuse; to cut off the connection of fan board and outside copper bar; thus ensure that outside copper bar can not be protected by triggering voltage, normally work to make equipment cabinet server.
In the present embodiment, metal-oxide-semiconductor as shown in Figure 2 is also comprised and the heat in parallel with it plugs in controller in fan board, when heat inserts fan board, the fan board input inserted in this heat can produce a larger transient current, the Copper Foil in fan board is caused to produce a larger equivalent inductance, this equivalent inductance is to metal-oxide-semiconductor as shown in Figure 2, heat plugs in controller, input capacitances etc. can produce a reverse induction voltage, this reverse induction voltage may damage metal-oxide-semiconductor, input capacitance etc., and then make in fan board, to occur that short circuit causes copper bar to occur over-current phenomenon avoidance, the actual output current of copper bar is caused to exceed its maximum supply current, this actual output current fusible safe silk, thus disconnect the connection of fan board and copper bar.
In fan board fault, when copper bar occurs that over-current phenomenon avoidance causes blown fuse, the metallic particles produced after this blown fuse may to be splashed in fan board or equipment cabinet server on other assemblies, may cause, to the damage of other assemblies in fan board or equipment cabinet server, causing the problem that fault coverage expands.Therefore, in order to the problem produced after preventing blown fuse, in a preferred embodiment of the invention, can to fuse outer cover protection tube, for when fuse is fused to equipment cabinet server in other assemblies form protection.
