A server automatic fire extinguishing system

Abstract

The invention discloses an automatic fire extinguishing system for a server. Smoke sensors are installed on the PCB; There is fire extinguishing material inside; there is a blowing port on one side of the turntable, and a blowing pipe is set on the outside of the rotating shaft in a gap. In the present invention, a smoke sensor is set on the air outlet of the chassis, a storage tank is set in the fan of the fan module, and the fire extinguishing material is filled inside the storage tank. When the smoke sensor detects that there is smoke in the system, it sends a signal After the BMC receives the smoke sensor signal, it controls the solenoid valve on the connecting pipe to open, and the fire extinguishing material is dispersed inside the system through the blowing port under the action of the wind flow, so as to realize the fire extinguishing demand and avoid the further spread of the fire. Further loss of personnel and property.

Description

technical field [0001] The invention belongs to the technical field of servers, in particular to an automatic fire extinguishing system for servers. Background technique [0002] The server is exposed to various environmental stresses during the product life cycle, including changes in temperature, humidity, voltage, and current. The accumulation of stress exceeds the rated range that parts and boards can withstand, resulting in high temperature and fire; the existing early warning mechanism is mostly monitored by using temperature sensors, which are read by BMC (Baseboard Management Controller) on the PCB board. The temperature sensing circuit on the computer and the built-in temperature value of the IC chip are used for calculation. When the temperature exceeds the set threshold, an alarm will be generated to notify the IT personnel. After receiving the alarm, the IT personnel will go to the scene to eliminate it. However, there is a time gap between the discovery of the ...

[0002] The server is exposed to various environmental stresses during the product life cycle, including changes in temperature, humidity, voltage, and current. The accumulation of stress exceeds the rated range that parts and boards can withstand, resulting in high temperature and fire; the existing early warning mechanism is mostly monitored by using temperature sensors, which are read by BMC (Baseboard Management Controller) on the PCB board. The temperature sensing circuit on the computer and the built-in temperature value of the IC chip are used for calculation. When the temperature exceeds the set threshold, an alarm will be generated to notify the IT personnel. After receiving the alarm, the IT personnel will go to the scene to eliminate it. However, there is a time gap between the discovery of the alarm and the arrival of the IT personnel at the scene, which makes this kind of passive management have the problem of low operation and maintenance efficiency; in addition, today's large server data centers generally adopt an unattended mode, when the server fails When the system catches fire, if the maintenance personnel cannot rush to the scene in time, it will cause huge loss of personnel and property
