Shell-and-Tube Heat Exchanger — Efficient and Reliable Heat Transfer Equipment Product Overview The shell-and-tube heat exchanger is a traditional, high-efficiency heat transfer device that transfers thermal energy between two fluids through a tubular structure. It consists of a tube bundle, tube sheets, a shell, and baffles. One fluid flows inside the tubes (tube side), while the other flows over the tubes on the shell side, with heat passing through the tube walls. Renowned for its robust co
The shell-and-tube heat exchanger is a traditional, high-efficiency heat transfer device that transfers thermal energy between two fluids through a tubular structure. It consists of a tube bundle, tube sheets, a shell, and baffles. One fluid flows inside the tubes (tube side), while the other flows over the tubes on the shell side, with heat passing through the tube walls. Renowned for its robust construction, broad adaptability, and ease of maintenance, this type of heat exchanger is widely used in industries such as petrochemical, power generation, pharmaceutical, food, and HVAC. It serves as essential equipment for process heating/cooling, waste heat recovery, and temperature regulation.
Two fluids at different temperatures enter the tube side and the shell side of the exchanger respectively. The tube-side fluid flows through the tubes, while the shell-side fluid is directed by baffles to repeatedly cross the tube bundle. Heat transfers from the hotter fluid to the cooler one through the tube walls, achieving the desired heating or cooling effect. Baffles not only increase the shell-side fluid velocity and turbulence for enhanced heat transfer efficiency but also support the tube bundle. Depending on process requirements, single-pass, double-pass, or multi-pass arrangements are available, and expansion joints can be included to accommodate thermal stress.
Robust and Durable Construction: With a mature design, it can endure high temperatures, high pressures, and corrosive media, delivering a long service life in demanding conditions.
Broad Adaptability: Capable of handling various fluid combinations—gas-liquid, liquid-liquid, vapor-liquid—across a wide range of operating temperatures and pressures.
Ease of Maintenance: The tube bundle can be pulled out for inspection or replacement, and tube-side cleaning is straightforward, making it suitable for services prone to fouling with routine cleaning.
Flexible Design: Can be designed per international and national standards such as ASME, GB/T 151, and TEMA. Various configurations are supported, including single/multi-pass, horizontal/vertical, and fixed-tubesheet/U-tube/floating-head types.
High Heat Recovery Efficiency: With optimized selection and baffle design, over 90% waste heat recovery can be achieved, significantly lowering production energy consumption.
