[0002] In the fields of chemical, pharmaceutical, food processing and many other industrial production, the reactor is the core equipment, and its heating and cooling efficiency plays a vital role in the quality and production efficiency of the entire chemical reaction process. The uniform heating and rapid cooling capabilities of the reactor are key factors to ensure the smooth progress of the chemical reaction, which directly affects the quality of the product and the continuity of production.

[0003] Existing reactors often face the problem of uneven heat distribution during the heating process, which not only causes changes in chemical reaction rate and selectivity, but may also cause local overheating or insufficient temperature, thus affecting the quality and consistency of the final product. In addition, the existing cooling system also has the problem of inefficiency, slow cooling speed, and inability to respond to the rapid temperature adjustment needs during the production process in a timely manner, which is particularly evident in processes that require fine control of reaction conditions.
