Shell and tube heat exchangers are one of the most widely used heat exchange devices in the industrial field. They have reliable structures and strong adaptability, and are suitable for high-temperature, high-pressure and high-flow working conditions. Its core design is composed of components such as the shell, tube bundle, tube sheet and baffle plate
It is composed of components such as the shell, tube bundle, tube sheet, baffle plate, and head. Each component can be independently designed or replaced (for example, changing the material of the tube bundle to adapt to different media), facilitating maintenance and customization.
Through the use of process separation baffles, multiple process combinations of the tube side (tube side) and the shell side (shell side) can be achieved (such as types 1-2, 2-4), flexibly adjusting the fluid path and flow rate, and optimizing the heat transfer efficiency.
The heat transfer area per unit volume is large, and the capacity can be expanded by increasing the length or quantity of the tube bundle, making it suitable for small-scale to large-scale industrial applications.
By adjusting the pipe diameter, arrangement method (triangle/square), and baffle plate spacing, the ratio of pressure drop to heat transfer is optimized (such as the pressure drop in the shell side is usually 10-50 kPa).
The fluid in the tube passageway enters from the head and flows within the tubes (either in a single direction or in multiple round trips).
The fluid in the shell passage enters from the shell inlet and flows outside the tube bundles, guided by baffles to form a tortuous path.
The high-temperature fluid transfers heat to the low-temperature fluid through the tube wall (by conduction), without direct contact between the two.
The efficiency of heat transfer depends on the fluid properties, flow rate, temperature difference, tube wall material and surface area.
The counter-flow has a larger temperature difference, resulting in higher heat exchange efficiency (commonly seen in multi-pass designs). The co-flow has a smaller temperature difference and is suitable for special conditions.
The baffles force the shell-side fluid to crosswise wash the tube bundle, breaking the boundary layer and increasing the heat transfer coefficient. Through the head separation, the tube-side fluid makes multiple round trips, prolonging the heat exchange time.
Cooling/Heating: For example, in power plant condensers and chemical reactor cooling.
Evaporation/Condensation: For instance, in evaporators of refrigeration systems and reboilers of distillation towers.
Waste Heat Recovery: Utilization of industrial waste heat.
