This water block is made of aluminum or copper, which offers high thermal conductivity and quickly dissipates heat generated by server chips (such as GPUs and CPUs). The micro-channel design enables the compact unit to deliver higher thermal efficiency within space-constrained servers. Vacuum brazing technology is used to join components such as the cold plate and connectors within the water block, ensuring that liquid cooling systems in data centers or liquid-cooled servers are free from the risk of leaks.
