It is mainly composed of components such as tube bundle, tube plate, shell, head, and baffle. The tube bundle is usually composed of a large number of heat exchange tubes, which are the core parts for heat transfer. Different temperatures of fluids flow inside and outside the tubes respectively; Tube plate is used to fix the tube bundle and separate the tube side from the shell side; The shell provides external protection for the entire device and accommodates the fluid in the shell side; The head plays a sealing role, and the baffle plate promotes multiple changes in the flow direction of the shell side fluid, enhancing the heat transfer effect.

The characteristics of shell and tube condenser are significant. Firstly, it has a sturdy structure, high reliability, can withstand high pressure and temperature, adapt to complex and harsh industrial environments, and has a long service life. Secondly, the heat transfer efficiency is considerable. Through reasonable arrangement of tube bundles and setting of baffles, the two fluids can fully contact and exchange heat, meeting the requirements of large-scale heat transfer. Furthermore, it has great operational flexibility and can operate stably even when working conditions such as flow rate and temperature change, with a wide range of adjustments and adaptability. In addition, its mature technology, relatively low manufacturing, installation, and maintenance costs, and outstanding cost-effectiveness advantages make it the "main force" of heat exchange in industrial production
