Abstract

The invention discloses an automatic pressure relief valve and a data disaster recovery storage device comprising the same. The automatic pressure relief valve comprises a valve body, a movable part and an elastic part, wherein a pressure relief hole is formed in the valve body; the movable part is configured to be capable of moving between a first position and a second position; when the movable part is located at the first position, the pressure relief hole is closed; and when the movable part is located at the second position, the pressure relief hole is opened, and the elastic part is used for providing elastic force facing the first position for the movable part. When the temperature gradually rises, the air pressure on one side of the pressure relief hole continuously rises along with the rise of the temperature, finally the elastic force of the elastic part is overcome, a gap is formed between the movable part and the valve body, cooling liquid can be discharged in a high-temperature and high-pressure steam state, and meanwhile, the temperature and the air pressure of a hollow cavity are reduced; and when the air pressure is reduced to a certain value, the elastic part pushes the movable part back to the first position, and the pressure relief hole is closed again. The process is repeated for multiple times until the cooling liquid is completely leaked, the cooling liquid can fully absorb heat, and the heat resistance durability of the data disaster recovery storage device can be improved.

Description

technical field

[0001] The invention relates to the technical field of data storage, in particular to an automatic pressure relief valve and a data disaster backup storage device including the same. Background technique

[0002] At present, some devices in vehicles, such as driving recorders, generally use built-in hard drives or SD cards to store vehicle data records. After an accident causes the vehicle to catch fire, crash, or fall into the water, the data memory (such as a built-in hard disk or SD card, etc.) is damaged due to poor protection, so that the driving data cannot be read, and the cause of the accident cannot be judged. Therefore, there is a data disaster recovery storage device for saving data storage. Protection against impact and falling water is relatively mature, but fire protection technology is not easy to realize under the premise of cost and volume constraints. In the data disaster recovery storage device in the prior art, the coolant utilization ef...
