What is a shell and tube heat exchanger?
This asymmetric design determines its wide range of applications in the field of steam-water heat transfer. The maximum heat transfer efficiency can reach 14000w / m2.k, greatly improve production efficiency and cost savings.
Greatly improving the efficiency of heat transfer, in 2012 also gradually spread in the domestic market. Shell and tube heat exchanger, spiral tube bundle design, can maximize the increase in turbulence effect, increase the heat transfer efficiency. Internal shell and tube asymmetry design, the maximum can reach 4.6 times.
Pipe models are different, the process is generally diameter 16mm 20mm or 25mm three models, the wall thickness is generally 1mm, 1.5mm, 2mm and 2.5mm. Imported heat exchanger, the minimum diameter can be 8mm, wall thickness is only 0.6mm.
In the case of heat transfer within the tube heat exchanger of the two kinds of fluid, a flow in the tube, the stroke called the tube; a flow outside the tube, the stroke called the shell. The wall of the tube is the heat transfer surface.
Shell and tube (also known as tube-type) heat exchanger is shell and tube heat exchanger mainly shell, tube bundle, tube plate and head and other components, the shell was round, with parallel tube bundles or spiral , Both ends of the tube bundle fixed to the tube plate.
