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. |

1. An apparatus for holding and cooling rack-mountable servers having heat-producing electronic components, comprising:
a tank defining an open interior volume and having a coolant inlet for receiving a dielectric liquid coolant within the open interior volume and having a coolant outlet for allowing the coolant to flow from the open interior volume, the coolant inlet and the coolant outlet being fluidly coupled to each other; a volume of dielectric liquid coolant in the tank; one or more mounting members positioned within the interior volume and configured to hold a plurality of rack-mountable servers in a horizontally stacked relationship with one another, with the rack-mountable servers in a vertical orientation within the interior volume such that the plurality of servers are commonly at least partially submersed in the volume of the dielectric liquid coolant; one or more pumps configured to move at least portion of the dielectric liquid coolant in the tank; one or more fluid velocity augmentations devices; and a liquid-to-liquid or liquid-to-refrigerant heat exchanger outside of the tank, wherein the volume of dielectric liquid coolant is thermally coupled to a distal location via the liquid-to-liquid or liquid-to-refrigerant heat exchanger, wherein at least one of the pumps, the coolant inlet, the coolant outlet, and the mounting members are configured such that the at least one pump is operable to move at least a portion of the dielectric liquid coolant vertically across heat producing components of one of the rack-mountable servers in parallel flow with dielectric liquid coolant moved vertically across heat producing components of at least one other of the rack-mountable servers, wherein each of at least one of the fluid velocity augmentation devices is configured to increase the velocity of flow of the dielectric liquid coolant through at least one of the rack-mountable servers or between adjacent ones of the rack-mountable servers, wherein the volume of dielectric liquid coolant comprises at least one passage in the tank that is outside of the rack-mountable servers, wherein, when the at least one pump is operated to move the dielectric liquid coolant vertically across the heat producing components, 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 the at least one passage, 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 such that heat is rejected to the distal location, wherein the one or more mounting members hold the rack-mountable servers such that at least one of the rack-mountable servers is independently removable, through an opening in the top of the tank, from the volume of dielectric liquid coolant while at least two other rack-mountable servers remain commonly submersed in the volume of dielectric liquid coolant in the tank and sufficiently submersed to maintain cooling by the flow of the dielectric liquid coolant in the tank across heat producing electronic components of the at least two other rack-mountable servers, wherein any one or more of the servers can be removed while at least one other of the servers remains operating. |
