1. A server rack, comprising:
a plurality of server chassis;
a separation chamber comprising inputs to respectively receive a mixed two-phase coolant from the plurality of server chassis, a vapor output at a top portion of the separation chamber, and a liquid output at a bottom portion of the separation chamber, wherein the separation chamber comprises a geometry that is configured the mixed two-phase coolant to a liquid and a vapor, direct the liquid to the liquid output, and direct the vapor to the vapor output;
a condenser that is fluidly connected to the vapor output of the separation chamber to receive and condense the vapor to the liquid; and
a main outlet that is fluidly connected to the liquid output of the separation chamber and fluidly connected to a condenser output of the condenser, wherein the main outlet of the server rack is fluidly connected to an external cooling system which supplies the liquid back to the server rack.
