Introduction of Shell and Tube Heat Exchanger

Definition: Shell and tube heat exchanger is a common type of heat transfer equipment used to transfer heat between two fluids of different temperatures to another fluid, commonly used in industrial and cooling systems.

Structure: It consists of a shell (casing), tube bundle and tube sheet, in which the heat transfer medium passes through the tube bundle and the two fluids flow through the inner and outer sides of the casing respectively.

Design points: the key includes the selection of pipe range, tube bundle arrangement, shell structure, etc., need to consider the nature of the fluid, flow rate, temperature difference and other factors.

Characteristics and advantages: Compared with plate heat exchanger, shell and tube heat exchanger has the advantages of high heat transfer efficiency, stable structure, easy maintenance and so on.

Difference Comparison:

Difference with plate heat exchanger: shell and tube type is suitable for high pressure, high temperature, large flow; plate type is suitable for low pressure, low temperature, small flow.

Difference with shell and tube heat exchanger: shell and tube type is mostly used for gas heat transfer, shell and tube type is mostly used for liquid heat transfer [7].

Common problems and solutions: including tube bundle clogging, leakage, uneven temperature and other issues, need to be regularly inspected and cleaned, replacement of seals and so on.

Application areas: widely used in chemical, petroleum, electric power and other industrial areas of cooling, heating, evaporation, condensation and other processes.

Above is the basic overview of shell and tube heat exchanger, which plays an important role in industrial production and energy field, improves the efficiency of energy utilization, and also provides a reliable heat transfer solution for industrial processes.
