This water block is made of copper, which offers high thermal conductivity and can quickly dissipate the heat generated by server chips (such as GPUs and CPUs). The water block uses vacuum brazing technology to join components such as the cold plate and connectors, ensuring that the liquid cooling system in data centers or liquid-cooled servers is free from the risk of leaks. The water block, along with components such as tubing and quick-connect fittings, can form a flexible and customizable liquid cooling loop.
