Wuhan Donghai has adopted patented single- and dual-shell anti-short-circuit helical baffle heat exchanger technology in numerous large-scale refining and chemical units, enabling optimized process calculations and structural design of the heat exchangers. This approach ensures not only cost-effective operation but also long-term efficiency for the equipment—features that outperform traditional bow-and-baffle heat exchangers.

The medium flows continuously and smoothly in a spiral pattern within the shell, eliminating the severe pressure losses caused by transverse flow redirection—thus giving it the advantage of low pressure drop. At the same pressure drop, this design significantly boosts the velocity of the shell-side fluid, enhancing the Reynolds number and, consequently, improving the medium's heat-transfer efficiency.
Keywords:
Currently, shell-and-tube heat exchangers are widely used in process industries in China, including petroleum, chemical, and power generation. Their dominant position among various types of heat exchange equipment stems from their versatility—capable of handling a wide range of challenging process conditions such as high temperatures, high pressures, and complex media.
