US Patent 10499488 Liquid-cooled integrated circuit system

A liquid-cooled integrated circuit system includes two printed circuit assemblies having removable heat spreaders and cooling pipes coated with a thermal interface material. The two printed circuit assemblies are placed together in opposition such that the top surfaces of the heat spreaders on each printed circuit assembly contacts, and become thermally coupled with, the thermal interface material on the cooling pipes of the other printed circuit assembly. In this arrangement, each printed circuit assembly is cooled by the other.
