AI Technical Summary

Technical Problem

Brayton cycle heat exchange equipment is prone to scaling in microchannels, which can clog the channels and affect the heat exchange effect. In addition, traditional cooling systems have a large number of cooling water inlets, which affects the environmental friendliness and structural safety and reliability of deep-sea platforms.

Method used

The Brayton direct contact circulation cooling system utilizes poorly water-soluble media such as carbon dioxide, helium, and xenon to directly contact filtered seawater for cooling, eliminating wall heat exchange and employing a direct contact main cooler, which enhances compactness and avoids scaling and clogging of microchannels.

Benefits of technology

It improves heat exchange capacity, reduces the number of cooling water inlets, enhances the compactness and safety reliability of the power system, avoids wall corrosion and leakage, and strengthens environmental adaptability.
