Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0020] The invention provides an active and controllable cooling device for a gas generating agent for a fire extinguishing device, such as figure 1 With the structure shown, the cooling device can perform active and controllable cooling, save fire extinguishing agent, and reduce costs.
[0021] like figure 1 The shown fire extinguishing device uses an active and controllable gas generating agent cooling device, including a starter 1, a chemical chamber 2 is provided in the starter 1, and a gas generating agent 3 is built in the chemical chamber 2, and the gas generating agent 3 will generate high-temperature gas. 2 is distributed with a release port 4, and high-temperature gas will be discharged from the release port 4; the drug chamber 2 is wrapped with an electric refriger...

The invention discloses an automatic controllable cooling device of an aerogenic agent for a fire-extinguishing device. The automatic controllable cooling device comprises a starter, wherein a medicament chamber is formed in the starter; an aerogenic agent is placed in the medicament chamber; release openings are formed in the medicament chamber; electrical refrigeration slices wrap the medicament chamber; a cooling channel is formed between two adjacent electrical refrigeration slices; discharging openings are formed in the outer electrical refrigeration slice. According to the automatic controllable cooling device of the aerogenic agent for the fire-extinguishing device disclosed by the invention, high-temperature gas can be changed into gas with a normal temperature or a temperature lower than the temperature that a fire extinguishing agent can be decomposed, and then is in contact with the fire extinguishing agent outside the starter, and the fire extinguishing agent is not decomposed in advance and is high in use ratio.
Description
technical field [0001] The invention relates to a fire extinguishing device, in particular to an active controllable cooling device for a gas generating agent used in a fire extinguishing device. Background technique [0002] The fixed non-storage fire extinguishing device is an atmospheric fire extinguishing device that does not need energy storage. It can be quickly activated in case of fire and is widely used in unattended places. The fire extinguishing device is composed of a shell, a fire extinguishing agent and a starter. Extinguishing agents include dry powder, foam, water, etc. [0003] In the existing non-storage fire extinguishing device, the starter uses a gas-generating agent such as hot aerosol agent or gunpowder. After receiving the start signal, the gas-generating agent expands rapidly, changes from solid to gas, breaks through the sealing port, and sprays the fire extinguishing agent into the fire scene to extinguish the fire. . [0004] Regardless of whet...
