Mar 14, 2019 · 3. U-tube heat exchanger Figure 3 U-tube heat exchanger structure diagram Figure 3 is a structural diagram of a U-tube heat exchanger. Each bundle of U-tube heat exchangers is made into a U-shape with different radii of curvature. Both ends are fixed on the same tube sheet and used. The partition divides the head into two chambers.
Comparing exergy losses and evaluating the potential of Feb 28, 2020 · The large increase in the required heat exchanger area in the spiral-wound heat exchangers is both due to the lower surface density and lower heat transfer coefficients. The state-of-the-art technology, plate-fin heat exchangers, is likely the best choice for the heat exchangers of a large-scale Claude refrigeration LH 2 process.
From the operation experience of heat exchange tubes, there are two kinds of extreme conditions, i.e. the low temperature condition (-196162°C) in gas separator/LNG industry and the high temperature condition (400~540°C) in refinery industry. As to the first condition, the medium is relatively clean.
