Technical Field

[0001] The utility model relates to the technical field of fire extinguishing tanks, in particular to a low-pressure carbon dioxide tank with a constant temperature function. Background Art

[0002] A fire extinguisher tank, also known as a fire extinguisher, is a portable fire-fighting tool that contains chemicals for extinguishing fires. It is one of the common fire prevention facilities and is stored in public places or places where fires may occur. It can be divided into portable and trolley types according to its mobility. Different types of fire extinguishers have their own specific scope of use and advantages. The correct selection and use of fire extinguishers is crucial to effectively control and extinguish early fires.

[0003] Low-pressure carbon dioxide cylinders are usually used to store liquid carbon dioxide. Low-pressure carbon dioxide fire extinguishing is highly economical, especially in large-scale engineering projects. As the scale of the project increases, its investment saving effect becomes more obvious.

When storing liquid carbon dioxide, it needs to be kept at an extremely low temperature. The insulation requirements are very high, and a series of measures need to be adopted to ensure the stability of the low-temperature environment. At present, low-pressure carbon dioxide cylinders usually use insulation materials to effectively reduce heat transfer and improve the insulation effect of the tank. However, relying on insulation materials to maintain the stability of the tank has certain limitations.
