Patent attributes
An electronic rack includes one or more servers, where each server is contained within a respective server container, and each server is at least partially submerged in two-phase liquid coolant, where, while the server generates heat that is transferred to the two phase liquid coolant thereby causing some of the two phase liquid coolant to turn into a vapor. The electronic rack includes a condenser container and condensing coils mounted at a top portion of the electronic rack to condense the vapor into the two-phase liquid coolant. The electronic rack includes a vapor manifold along a length of the electronic rack, the vapor manifold coupling the condenser container to a respective server, where the vapor manifold carries the vapor from the servers to the condensing coils. The electronic rack includes a first return line coupled to the condenser container, to return the two-phase liquid coolant to a coolant unit.
