Description

A structure for reducing input voltage fluctuation of fan plate

technical field

The invention belongs to the technical field of server fan design, and in particular relates to a structure for reducing input voltage fluctuations of a fan board.

Background technique

With the development of network applications, informatization has gradually covered all areas of society. People's daily work and life are more and more communicated through the network, and the requirements for stable server work are also increasing.

In the server system, the fan is the most important heat dissipation part. In the rack server architecture, the fan board that supplies power to the fan adopts the power supply method of the copper bar of the whole cabinet, that is, after taking power from the copper bar of the whole cabinet, through The fan board supplies power to multiple fans. The power supply stability of the fan board will directly affect the working efficiency of the fan, and then affect the heat dissipation performance of the server.

In the prior art, in the rack server architecture, the fan board input cables are routed in parallel, that is, the 4 power wires and the 4 ground wires are powered from the copper bar and then inserted into the fan board input connector in parallel. The voltage fluctuation caused by the coupling effect between cables reduces the stability of the input voltage of the fan board, causing the fan to fail to work normally. This is the weak point of prior art.

Therefore, aiming at the above-mentioned defects in the prior art, it is provided to design a structure for reducing the input voltage fluctuation of the fan board.

The beneficial effect of the present invention is that the power wire and the ground wire are wound in a spiral, and then respectively connected to the input connector of the copper row and the fan board. After power-on, the current on the four power supply wires flows from the copper row to the fan board, generating a magnetic field The direction is clockwise; the current on the four ground wires flows from the fan plate to the copper bar, and the direction of the magnetic field generated is counterclockwise. The two are close to each other due to spiral winding, and cancel each other out, which greatly weakens the magnetic field effect. The voltage fluctuation ensures the power supply stability of the input voltage of the fan board.

In addition, the design principle of the present invention is reliable, the structure is simple, and has very wide application prospects.

It can be seen that, compared with the prior art, the present invention has outstanding substantive features and remarkable progress, and the beneficial effects of its implementation are also obvious.
