AI Technical Summary

Technical Problem

Existing cold plate liquid cooling circulation systems suffer from complex system architecture, energy efficiency loss and reliability challenges due to heat transfer temperature differences, and numerous maintenance nodes.

Method used

The internal piping of the liquid-cooled plate is directly connected to the external heat dissipation piping by using inlet and outlet water manifolds, eliminating the need for heat exchangers. It uses a single coolant and is equipped with redundant pumping capacity. Combined with a constant volume exhaust mechanism and water replenishment system, the piping design is optimized to reduce the impact of gas.

Benefits of technology

The system structure has been simplified, energy efficiency has been improved, reliability and maintenance convenience have been enhanced, cooling effect has been ensured, and stable circulation has been achieved through an automatic exhaust and water replenishment system.
