AI Technical Summary
In existing liquid cooling systems for mainframe cabinets, impurities in the coolant are prone to deposit, leading to increased flow resistance, uneven flow distribution, and localized blockages, which affect heat dissipation efficiency. Furthermore, long-term operation requires frequent replacement of coolant and disassembly and cleaning of cold plates, increasing labor costs and equipment instability.
A direct liquid-cooled assembly cabinet heat dissipation device was designed, which includes a filter frame, a roller brush, and a scraper. The filter frame filters impurities, and the automatic replacement of the filter frame achieves seamless connection. Combined with the roller brush and scraper, automatic cleaning is performed, reducing manual intervention and maintaining stable operation of the device.
It effectively filters impurities in the coolant, avoids increased flow resistance and blockage caused by sedimentation, ensures heat dissipation efficiency, achieves automatic cleaning, reduces downtime risk, and lowers operation and maintenance costs.
