What Is A U Tube Bundle Heat Exchanger?
U-shaped tube heat exchanger refers to a shell-and-tube heat exchanger in which the tube bundle is composed of U-shaped tubes with different bend radii and both ends of the tubes are fixed on the same tube sheet.
Since each U-shaped tube can be freely stretched, there will be no temperature differential stress between the tube bundle and the shell. Baffles, longitudinal partitions, etc. are arranged in the shell side.
The baffles are fixed by tie rods. The longitudinal baffle is a rectangular flat plate installed parallel to the heat transfer tube to increase the flow rate of the medium on the shell side.
Product features of U-shaped tubular heat exchanger:
Simple structure, only one tube sheet, less sealing surface, reliable operation and low cost; the tube bundle can be pulled out, and the cleaning between the tubes (shell side) is convenient. Light weight, suitable for high temperature and high pressure occasions.
The U-shaped tubular heat exchanger is suitable for the occasions where the temperature difference between the tube and the shell wall is large or the medium on the shell side is easy to scale, but the medium on the tube side is clean and not easy to scale, and the high temperature, high pressure and strong corrosion are occasions.
Generally, the medium with high temperature, high pressure and strong corrosiveness runs in the pipe, but the high pressure space is reduced, the sealing is easy to solve, and the material can be saved and heat loss can be reduced.
U-tube heat exchangers are widely used in automobile, aviation, petrochemical, power, medicine, metallurgy, refrigeration, light industry, food, construction machinery and other industries.
