Preliminary specification for a closed loop liquid cooling system product reliability test plan

Future high performance systems may incorporate liquid cooling to the board. These systems will be assembled using commercially available components and subsystems, which include the pump, liquid coolant, tubing and connections, heat exchanger, and cold plate. Liquid cooling systems are known to be susceptible to more degradation and failure mechanisms than conventional solid metal heatsinks, heat pipe heatsinks or vapor chamber heatsinks. Component and system providers need guidelines to ensure that their products meet projected reliability requirements. A generic preliminary specification has been assembled based on industry standards and information collected from leading equipment suppliers.
