摘要： A fluid distribution apparatus for servers mounted onto a rack. The apparatus includes one or more pairs of distribution units that are rotationally symmetric and are attached to each other to form the pair. Each of the distribution units includes a main supply port and main return port that are connected to the rack's fluid manifolds. Each of the distribution units also includes plurality of supply and return connectors that connect to the servers. A pump in each of the distribution units delivers fluid from the rack's fluid manifolds to the servers for cooling. Each server is connected to fluid ports on both distribution units, so as to provide full redundancy. A controller receives signals form the servers and sends operation signals to the pumps to control the fluid delivery for cooling the servers.

摘要： A two-phase immersion cooling system for cooling electronics. The electronics are immersed in immersion tank filled with phase change liquid. As liquid evaporates due to heat generated by the electronics, it enters a vapor passageway that leads the vapor to a condenser situated remotely from the immersion tank. Upon condensing at the condenser, the condensed liquid is directed to a resupply tank, wherein the condensed liquid cools. When the level of the two phase liquid in the immersion tank drops below a set threshold, a pump is activated to deliver the condensed liquid from the resupply tank to the immersion tank. The immersion tank, vapor passageway and condenser are position inside a containment passageway. The containment passageway captures any vapor not entering the vapor passageway and direct such vapor to the condenser. An air mover generates pressure differential within the containment passageway to direct the vapor towards the condenser.
