| 1. A complete, forced-circulation, liquid cooling system for cooling heat-generating components in an electronic system comprising:
one or more heat transfer units coupled to one or more heat-generating components for receiving cooled liquid coolant and
generating heated liquid coolant by transfer of heat from the heat-generating components to the liquid coolant;
a heat exchange unit having a heat dissipater for receiving heated liquid coolant from the heat transfer units and generating
cooled coolant for transportation to the heat transfer units;
a forced circulation means disposed within the heat exchange unit in proximity to the dissipater for forcing transportation,
at accelerated rates, of cooled liquid coolant from the heat exchange unit to the heat transfer units and of heated liquid
coolant from the heat transfer units to the heat exchange unit;
a liquid coolant pathway for delivery of the cooled liquid coolant from the heat exchange unit to the heat transfer units
and for delivery of the heated liquid coolant from the heat transfer units to the heat exchange unit; and
wherein the complete liquid cooling system has no component acting as a liquid coolant reservoir while the liquid cooling
system is in operation.
