Abstract The constant temperature tank as industrially important pressure vessel equipment, used in metallurgy and chemical industry, food processing, bio fermentation, health and other fields, the temperature control system is widely used in heating furnace, fermentation tank, water supply system, hot water temperature control system. With the development of computer control technology, constant temperature control has been widely used in the field of industrial production, and has made great economic and social benefits. This design first introduces the basic knowledge of the container, including the classification and structure of the pressure vessel, the type and selection of the head, the parts of the container, heating device design, etc.. Then, taking the design of the heating constant temperature storage tank as an example, the author gives a brief account of the mild design of the internal pressure thin wall cylinder and the standard elliptical head and the selection of the main parts of the container and the constant temperature control.

Key words: heating; constant temperature storage tank; head; heating device; strength check; constant temperature control;
