Heat exchangers, also known as heat exchangers, are devices that transfer a portion of the heat from a hot fluid to a cold fluid. They are widely used in various industrial sectors such as chemicals, petrochemicals, power, food, and many others, holding a significant position in production. In chemical production, heat exchangers can act as heaters, coolers, condensers, evaporators, and reboilers, with a broader range of applications. There are many types of heat exchangers, but they can generally be categorized into three main types based on the principles and methods of heat exchange between the cold and hot fluids: wall-type, mixed-type, and regenerative-type. Among these three types, wall-type heat exchangers are most commonly used.
Shell and Tube Heat Exchanger Types
According to the principle of operation, they can be categorized into partitioned heat exchangers, regenerative heat exchangers, and mixed heat exchangers.
Coolers, heaters, condensers, and vaporizers can be categorized based on their application purposes.
According to the structural material, heat exchangers can be divided into metal material heat exchangers and non-metallic material heat exchangers.
Heat exchangers are categorized into tubular and plate-type based on the shape and structure of the heat transfer surface.
According to usage, they can be categorized into collective heating heat exchangers and residential heat exchangers.
