[0002] Pressure vessels are widely used for storing and transporting various gases and liquids, including industries such as chemical engineering, petroleum, natural gas, and food processing. In many applications, the gas or liquid inside the pressure vessel needs to maintain a specific temperature range to ensure work efficiency and safety.

[0003] Especially in the production processes of industry and chemical engineering, maintaining the temperature stability inside the pressure vessel is crucial. Excessive or too low temperature may cause safety risks. For example, overheating may lead to the explosion of the container, while too cold may cause problems such as solidification or liquefaction of the material.

[0004] Traditional cooling methods for pressure vessels usually include external radiators or heat exchangers, which cool down by transferring the heat outside the heat source body to the surrounding environment. This method is sometimes inefficient, especially under working conditions such as high temperature and high pressure where efficient heat transfer is required.

[0005] Some applications require a more efficient internal cooling method to ensure rapid and effective reduction of the temperature of the heat source body to meet safety and production requirements. Summary of the Utility Model
