This paper describes the design and attributes of an advanced
liquid cooling system that can cool single or multiple heat
sources within the computer system. The cooling system
described use copper cold plates with meso scale channels to
pick up heat from CPU and GPU type heat sources and highly
efficient liquid-to-air heat exchangers with flat copper tubes
and plain fins to transfer the heat to air by forced convection. A
water based coolant is used for high thermal performance and
additives are used to provide burst protection to the cooling
system at temperatures down to -40 ο
C and corrosion protection
to critical components. A highly reliable compact pump is used
to circulate the fluid in a closed loop. The overall system is
integrated using assembly methods and materials that enable
very low fluid permeation for long life.
