➀ The development of a full liquid cooling system is based on the high-density computing server i24, supporting two Intel fifth-generation Xeon processors per node. ➁ The system achieves a 95% heat removal rate through liquid cooling, with the remaining 5% managed by a rear-mounted air-liquid heat exchanger. ➂ The design focuses on high energy efficiency, low cost, and ease of maintenance, exploring liquid cooling solutions for high-power memory, SSDs, OCP network cards, and more.
