An apparatus for cooling a plurality of rack-mountable servers containing heat generating electronic components in a server room including a dielectric liquid cooling apparatus located inside the tank and a secondary cooling apparatus comprising a remote heat exchanger and at least one pump. The volume of dielectric liquid coolant comprises at least one passage in the tank that is outside of the vertically oriented rack-mountable servers. When the at least one pump is operated to move the dielectric liquid coolant vertically across the heat producing components on the vertically oriented servers, a circuit is formed in which a first portion of dielectric liquid coolant is moved vertically upward across the heat producing components on the vertically oriented servers and then downward outside of the rack mountable servers in the at least one passage, while a second portion of the dielectric liquid coolant flows out of the tank.

Liquid submerged, horizontal computer server rack and systems and method of cooling such a server rack

Apparatus, systems, and methods for efficiently cooling computing devices having heat-generating electronic components, such as, for example, independently operable servers, immersed in a dielectric liquid coolant in a tank.

An apparatus for holding and cooling rack-mountable servers having heat-producing electronic components includes a tank, a volume of dielectric liquid coolant in the tank, mounting members that hold rack-mountable servers in the tank, one or more pumps, fluid velocity augmentations devices, and a liquid-to-liquid or liquid-to-refrigerant heat exchanger outside of the tank. The mounting members hold the rack-mountable servers in a vertical orientation within the tank such that the servers are commonly submersed in the volume of the dielectric liquid coolant. When a pump is operated to move the dielectric liquid coolant vertically across the heat producing components of the rack-mountable servers, a circuit is formed in which a first portion of heated dielectric liquid coolant is moved vertically upward across the heat producing components and then downward outside of the rack mountable servers in a passage external to the rack-mountable servers, while a second portion of heated dielectric liquid coolant flows out of the tank and through the liquid-to-liquid or liquid-to-refrigerant heat exchanger.
