Claim 10:
11. A system, comprising:
a server having a plurality of heat sources; and
an electronic cooling apparatus packaged with the server, the electronic cooling apparatus including:
a plurality of cold plates to extract heat from the heat sources, respectively;
a plurality of vapor separators, each of the vapor separators to receive mixed phase fluid and separate the mixed phase fluid into a vapor and a cooling liquid; and
a return unit to receive the vapor from each of the vapor separators through a plurality of vapor loops, and dissipate the received vapor from a vapor dissipation portion of the return unit;
wherein the plurality of cold plates comprise:
a first cold plate that receives a first cooling liquid through an inlet of the electronic cooling apparatus to extract the heat from a first heat source among the heat sources, produces a first mixed phase fluid, and supplies the first mixed phase fluid to a first vapor separator among the plurality of vapor separators, and
a second cold plate that receives a second cooling liquid from the first vapor separator, uses the second cooling liquid from the first vapor separator to extract the heat from a second heat source among the heat sources, produces a second mixed phase fluid, and supplies the second mixed phase fluid to the return unit or to a second vapor separator among the plurality of vapor separators.
