[0022] To fully understand the present invention, detailed structures will be presented in the following description to illustrate the technical solutions proposed by the present invention. The alternative embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may have other embodiments.

[0023] Please refer to the attached Figures 1 to 2, this application provides a fireproof data storage device, including a chassis 1 in which a plurality of storage processors are placed. An interface is provided on the outer shell of the chassis 1, and the interface is connected to the storage processors. A fixing plate 2 is provided at the top of the inner cavity of the chassis 1, and the fixing plate 2 is detachably connected to the fire extinguishing unit. A small gas storage tank 3 is also provided at the top of the chassis 1. The outlet end of the small gas storage tank 3 extends into the fire extinguishing unit through a gas guide pipe 4. A plurality of gas outlets 5 are provided on the fire extinguishing unit, and the gas outlets 5 are communicated with the inner cavity. The fire extinguishing unit generates a flame retardant gas when the temperature reaches a threshold value and outputs the flame retardant gas through the gas outlets 5.

[0024] In the fireproof data storage device provided by this embodiment, a plurality of storage processors are placed in the chassis 1. An interface is provided on the outer shell of the chassis 1 and is connected to the storage processors for a data cable to be connected to the interface to transmit data to the storage processors. When the temperature in the chassis 1 reaches an abnormal threshold value, its fire extinguishing unit generates a flame retardant gas, and the flame retardant gas enters the chassis 1 through the gas outlets 5 to achieve flame retardance inside the chassis 1. When it is necessary to further increase the flame retardant intensity, gases such as nitrogen are introduced from the small gas storage tank 3 into the fire extinguishing unit, so that the nitrogen and the flame retardant gas generated by the fire extinguishing unit form a mixed fire extinguishing gas, and the mixed fire extinguishing gas enters the chassis 1 through the gas outlets 5 to achieve a better flame retardant and fire extinguishing effect.

[0025] In a possible embodiment, the fire extinguishing unit includes a heat-conducting housing 6 and a sodium bicarbonate filling layer 7. A partition 8 and a mesh plate 9 are provided inside the heat-conducting housing 6. The mesh plate 9 is arranged on both sides of the partition 8, and the sodium bicarbonate filling layer 7 is arranged between the partition 8 and the mesh plate 9. The gas guide pipe 4 passes through the mesh plate 9, and a gas outlet 5 is provided on the heat-conducting housing 6.

[0026] Specifically, the heat-conducting housing 6 transfers the heat in the chassis 1 to the sodium bicarbonate filling layer 7. When the temperature in the sodium bicarbonate filling layer 7 reaches a threshold value, for example, 50 °C, sodium bicarbonate decomposes into carbon dioxide upon heating, and the carbon dioxide passes through the holes of the mesh plate 9 and is finally output to the inside of the chassis 1 through the gas outlet 5 to achieve flame retardance.

[0027] Furthermore, when the temperature rises further, gases such as nitrogen are introduced from the small gas storage tank 3 into the fire extinguishing unit, so that the nitrogen and carbon dioxide form a mixed fire extinguishing gas. The mixed fire extinguishing gas passes through the holes of the mesh plate 9 and is finally output to the inside of the chassis 1 through the gas outlet 5 to further achieve flame retardance, thereby improving the flame retardant efficiency.

[0028] In a possible implementation, connecting plates 10 are provided at both ends of the heat-conducting housing 6. The connecting plates 10 are engaged with the fixing plate 2, and the engaged part is fixed by bolts. When installing or removing, only need to open the chassis 1, loosen / tighten the bolts, and then the heat-conducting housing 6 can be removed from or installed on the connecting plates 10.

[0029] In a possible implementation, the air duct 4 includes a first pipe body 401 and a second pipe body 402. One end of the second pipe body 402 passes through the heat-conducting housing 6 and is inserted into the first pipe body 401, and the other end passes through the mesh plate 9. One end of the first pipe body 401 is connected to the small gas storage tank 3, so that the second pipe body 402 is fixed inside the heat-conducting housing 6.

[0030] Specifically, both the first pipe body 401 and the second pipe body 402 are flexible hoses. A connector 14 is provided at the connection part of the first pipe body 401 and the second pipe body 402. The connector 14 is a clamp-type connector. Only need to insert the second pipe body 402 into the connector 14 to achieve fixation and gas transmission. It should be noted that the way of inserting and fixing the first pipe body 401 to the second pipe body 402 through the connector 14 is a conventional means for those skilled in the art, and no specific structural description is given here.

[0031] Furthermore, the second pipe body 402 is fixed inside the heat-conducting housing 6 to maintain the stability of the gas transmission process.

[0032] In a possible implementation, a solenoid valve 11 is provided at the outlet end of the small gas storage tank 3. The solenoid valve 11 is connected to the first pipe body 401. A sensor 12 and a controller 13 are provided inside the chassis 1. The sensor 12 is signal-connected to the controller 13, and the controller 13 is connected to the solenoid valve 11.

[0033] Specifically, the sensor 12 includes a smoke sensor and a temperature sensor. The controller 13 is arranged on the top of the chassis 1. The smoke sensor and the temperature sensor are arranged on the inner wall of the chassis 1 or the fixing plate 2 to sense smoke signals and temperature signals. The smoke signals and temperature signals are sent to the controller 13. The controller 13 gives corresponding action signals to the solenoid valve 11 based on the smoke signals and temperature signals, so as to drive the solenoid valve 11 to open, so that the gas in the small gas storage tank 3 enters the heat-conducting housing 6 along the first pipe body 401 and the second pipe body 402 and mixes with the carbon dioxide gas.

[0034] The above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the said claims.
