Abstract
The present invention relates to a kind of structure for reducing fan board input voltage fluctuation, including fan board input connector, it is characterized in that, described fan board input connector passes through ground connection, described fan board input connector is connected to feeder ear, described ground wire and power line spiral windings by power lines.Power lines and ground wire spiral winding, the input connector of copper bar and fan board is then separately connected to, after energization, the electric current on 4 power supply power lines flows to fan board from copper bar, and caused magnetic direction is clockwise；Electric current on 4 piece-root grafting ground wires flows to copper bar from fan board, caused magnetic direction is counterclockwise, both is close to each other because of spiral winding, cancel out each other, greatly reduce the electrical stability that because of voltage pulsation caused by magnetic field effect, ensure that fan board input voltage.
Description
Technical field
The invention belongs to server fan design field, and in particular to a kind of reduction fan board input voltage fluctuation
Structure.
Background technology
The development of adjoint network application, informationization are gradually coated on the every field of society.The routine work life of people
More and more exchanged by network, it is desirable to which the requirement of server working stability is also being continuously increased.
In server system, fan is most important radiator portion, and the fan board to fan power supply is in rack servers
In framework, by the way of the power supply of whole machine cabinet copper bar, i.e.,：After power taking on the copper bar of whole machine cabinet, multiple wind are given by fan board
Fan power supply.The electrical stability of fan board can directly affect the operating efficiency of fan, and then have influence on the heat dispersion of server.
In the prior art, in rack server architectures, cable is inputted to fan board using parallel cabling, i.e., 4
Power lines and 4 piece-root grafting ground wires are inserted in parallel into fan board input connector after copper bar power taking.Because the coupling effect between cable is drawn
The voltage pulsation risen reduces the stability of fan board input voltage, causes fan can not normal work.This be prior art not
Foot part.
Therefore, for drawbacks described above of the prior art, there is provided a kind of knot for reducing fan board input voltage fluctuation of design
Structure.
The content of the invention
It is an object of the present invention in view of the above-mentioned drawbacks of the prior art, a kind of reduction fan board of offer design is defeated
Enter the structure of voltage pulsation, to solve above-mentioned technical problem.
To achieve the above object, the present invention provides following technical scheme：
A kind of structure for reducing fan board input voltage fluctuation, including fan board input connector, it is characterised in that described wind
Fan plate input connector is connected to feeder ear by ground connection, described fan board input connector by power lines, institute
The ground wire and power line spiral windings stated.
Preferably, described ground wire is provided with 4, the respectively first ground wire, the second ground wire, the 3rd ground wire
And the 4th ground wire；Described power lines are provided with 4, respectively the first power lines, the 2nd power lines, the 3rd power
Line and the 4th power lines.
Preferably, described first ground wire and the first power lines spiral winding be into the first helix, described second
Ground wire is grounded and the 3rd power line spiral windings with the 2nd power lines spiral winding into the second helix, the described the 3rd
Into the 3rd helix, the described the 4th ground wire is with the 4th power lines spiral winding into the 4th helix；First helix,
Two helixes, the 3rd helix and the 4th helix spiral winding.
Preferably, the first described ground wire, the second ground wire, the 3rd ground wire and the 3rd ground wire spiral winding
Into the first helix, described the first power lines, the 2nd power lines, the 3rd power lines and the 4th power line spiral windings
