AI Technical Summary
Existing heat exchangers have low pressure ratings, single channels that cannot be independently adjusted for heat, and low plate heat exchange efficiency. They cannot be adapted to both closed-loop cooling and open-loop water supply systems in wells at the same time, and are susceptible to high temperature, high humidity and dust in wells, leading to frequent failures and shortened lifespan.
The multi-channel core-shell heat exchanger adopts a cylindrical shell pressure bearing and plate bundle pressure self-balancing design. It utilizes 316L stainless steel plate bundles to form a permanent metallurgical seal through brazing process. Combined with superhydrophobic coating and chemical nickel plating layer, it achieves high pressure bearing, non-interference of multiple fluid channels and independent heat adjustment. The whole unit design meets the 10MPa pressure bearing requirement, and the built-in pressure stabilizing pipe ensures the pressure balance inside the shell.
It achieves efficient multi-channel independent heat regulation, meets the high-pressure water supply requirements downhole, improves heat exchange efficiency and equipment life, avoids the influence of external environment, adapts to complex downhole working conditions, and has anti-corrosion, anti-wear and anti-scaling functions.
