Customised design of a water-cooled cold plate fabricated by selective laser melting

A water-cooled cold plate which is capable of dissipating up to 320 W of heat while maintaining the surface temperature below 33°C has been successfully fabricated by selective laser melting (SLM) using aluminium alloy, AlSi10Mg, as the base powder due to its high thermal conductivity to specific...
