Specifically, each of the main fan groups 20 is respectively disposed corresponding to one or more servers 10 such that the air blowing direction of the main fan group 20 faces the corresponding server 10, thereby dissipating heat for the server 10.

The server cabinet 100 is further provided with a spare fan group 30 for dissipating heat to the corresponding server 10 instead of the stopped main fan unit 20 when any of the main fan groups 20 fails to operate. The main fan group 20 and the backup fan group 30 each include at least one cooling fan.

In this embodiment, the server cabinet 100 is provided with a transport mechanism 200, which carries the spare fan group 30, and can drive the spare fan group 30 to move in the server cabinet 100 to drive the spare fan group. 30 corresponds to the corresponding server 10, so that instead of the stopped main fan group 20, the corresponding server 10 is dissipated. Viewed from a top view, for example, as shown in FIG. 2, the server 10, the main fan pack 20, and the backup fan pack 30 are respectively located on different planes. The plane where the main fan group 20 is located and the plane where the backup fan group 30 is located are separated by a certain distance, so that the standby fan group 30 is not hindered by the main fan group 20 when sliding on the sliding mechanism 22.

Specifically, the transport mechanism 200 includes a sliding mechanism 22 and a connecting member 21 disposed on opposite side walls of the server cabinet 100. The sliding mechanism 22 defines two sliding trajectories. The connecting member 21 connects the spare fan group 30 to the sliding mechanism 22 and slides on a sliding track defined by the sliding mechanism 22 under the driving of a driving motor 40.

In addition, a motor controller 50 and a fan controller 60 are further disposed on the server cabinet 100. The drive motor 40 is used to drive the transport mechanism 200 to move the spare fan pack 30 on the slide mechanism 22. The motor controller 50 is used to control the operation of the drive motor 40. The fan controller 60 is configured to control the working states of the main fan group 20 and the backup fan group 30, for example, controlling the rotational speeds of the fans in the rotating main fan group 20 and the backup fan group 30, and monitoring the operating status of the fans.

In this embodiment, the main fan group 20, the backup fan group 30, the drive motor 40, the motor controller 50, and the fan controller 60 constitute a heat dissipation control system that dissipates heat from the servers in the server cabinet 100.

As shown in FIG. 3, it is a schematic diagram of the connection of the components of the heat dissipation control system.

The fan controller 60 is electrically connected to each of the main fan group 20, the backup fan group 30, and the motor controller 50. The fan controller 60 immediately monitors the operating state of the main fan group 20, and sends a trigger signal to the motor controller 50 when it detects that any of the main fan groups 20 has failed to operate. In this embodiment, the trigger signal includes location information indicating the failure of the main fan group 20, and the like. The fan controller 60 may be a baseboard management controller (BMC) disposed on the server cabinet 100 for monitoring the server 10 or a control component such as a motherboard of the server 10.

When the trigger signal is received, the motor controller 50 controls the driving motor 40 to drive the transport mechanism 200 to move the backup fan group 30 to the corresponding position of the faulty main fan group 20, instead of the trigger signal. The failed main fan group 20 dissipates heat from the corresponding server 10.

In this embodiment, the motor controller 50 first calculates the distance that the standby fan group 30 needs to move according to the trigger signal, and then sends a control command to the driving motor 40 according to the calculated distance to move the standby fan group 30 accordingly. distance. Specifically, each main fan pack 20 position and its distance relative to the spare fan pack 30 may be pre-stored in the motor controller 50, and then the motor controller 50 may be directly based on the location of the failed main fan pack 20. The distance that the spare fan group 30 needs to move is obtained. The drive motor can be, but is not limited to, a traction motor.

When the backup fan group 30 is moved to the corresponding position of the failed main fan group 20, the fan controller 60 controls the standby fan group 30 to start working and sends an alarm signal, for example, an audible alarm signal is transmitted through the buzzer and/or Or send a text message to an administrator device (such as a computer or a mobile phone) through any server 10 to notify the administrator to process the failed main fan group 20.

When the fan controller 60 monitors that the failure of the failed main fan group 20 is released and resumes operation, the fan controller 60 controls the standby fan group 30 to stop operating. Then, the fan controller 60 sends a reset signal to the motor controller 50, so that the motor controller 50 controls the drive motor 40 to drive the transport mechanism 200 to drive the backup fan pack 30 back to the initial position of the spare fan group. It is set in advance.

It should be understood that in other embodiments, the backup fan set 30 can also be manually moved to the corresponding position of the failed main fan set 20 and the initial position. That is to say, when the standby fan group 30 is manually controlled, some of the components in the heat dissipation system may be omitted, and for example, the drive motor 40, the motor controller 50, and the fan controller 60 may be omitted.

In summary, the present invention can improve the server in the server cabinet 100 by using a spare fan group 30 to temporarily replace the faulty main fan group 20 to dissipate the corresponding server 10 when the main fan unit 20 fails. 10 stability.
