Spiral-tube heat exchangers consist of one or more spirally wound coils which are, in circular pattern, connected to header from which fluid is flowed. This spiral coil is installed in a shell another fluid is circulated around outside of the tube, leads to transfer the heat between the two fluids.
Apr 25, 2015 · A spiral wound heat exchanger (SWHE) consists of a single bundle or multiple bundles. In each bundle, hundreds of tube layers are wound helically around a central core with an alternating winding direction from one layer to the next. Multiple streams flow in parallel tube layers exchanging heat with a common shell-side refrigerant in downward flow. Design Technology of Large-scale Spiral Wound Heat Spiral wound heat exchanger (SWHE) was first introduced in China because of the construction of the fertilizer industry in the last century. In synthetic ammonia units, Texaco gasification, Linde methanol washing and Topsoe synthesis are important process routes.
Apr 01, 2018 · At the same time, due to its advantages of high reliability, high compactness, high flexibility, better robustness, efficient heat transfer, and so on, spiral-wound heat exchanger (SWHE) has been widely applied as main cryogenic heat exchanger in large-scale onshore LNG plants , , , , and also has an enormous potential in FLNG plants , . Process calculation method and optimization of the spiral Apr 01, 2018 · Spiral-wound heat exchangers (SWHEs) is a special compact shell and tube heat exchangers, whose unit volume has a large heat transfer area, about 100170 m 2. With the development of China's industry and the continually improvement of energy efficiency, the comprehensive efficiency of the heat exchangers requirements are increasingly strengthened.
The consistent length of the heat exchanging cylinders and the precise core and interlayer spacing make the medium have a strong turbulent effect when flowing through the shell and tube, which greatly improves the efficiency of heat transfer. The heat transfer ability is 3-7 times greater than the conventional heat exchanger, and the maximum heat transfer coefficient can reach 14000W/. Spiral Wound Tube Heat Exchanger, innovated high efficient Spiral Wound Tube Heat Exchanger make new inovation on Tube Side. By development of Spiral Wound Tube bundle, which could create strong turlulent flow in tube side. It greatly improves the efficiency of thermal transfer, 3~7 times higher than conventional Tube and Shell Heat Exchanger. The Max. heat transfer coefficient could reach 14000W/.
