Abstract
Technology is provided for a server facility cooling system. The system can include a coolant tank containing an electrically insulating liquid and one or more servers submerged in the liquid. At least a portion of the heat generated by the servers is transferred to the liquid. An elongate cooling loop extends vertically between a first end and a second end, wherein the first end is located in the air and the second end is located underground. A heat exchanger is positioned between the coolant tank and the cooling loop to transfer heat from the liquid to the cooling loop. A cylindrical cooling tower is positioned around the first end of the cooling loop.
Claims10
A server cooling system, comprising:
- a tank containing an electrically insulating liquid;
- one or more servers submerged in the liquid, wherein at least a portion of the heat generated by the one or more servers is transferred to the liquid;
- an elongated cooling loop extending vertically between a first end portion and a second end portion, wherein the first end portion is located in the surrounding air and the second end portion is located beneath the surface of the earth;
- and
- a heat exchanger positioned between the tank and the cooling loop configured to transfer heat from the liquid to the cooling loop,
- wherein the heat exchanger comprises a thermally conductive wall in contact with the liquid on one side and in contact with the cooling loop on an opposite side.
A server cooling system, comprising:
- a coolant tank containing an electrically insulating liquid;
- one or more servers submerged in the liquid, wherein at least a portion of the heat generated by the one or more servers is transferred to the liquid;
- an elongated cooling loop extending vertically between a first end portion and a second end portion, wherein the first end portion is located in the surrounding air and the second end portion is located beneath the surface of the earth;
- a heat exchanger positioned between the coolant tank and the cooling loop configured to transfer heat from the liquid to the cooling loop;
- and
- a cylindrical cooling tower positioned around the first end portion of the cooling loop,
- wherein the heat exchanger comprises a metal wall in contact with the liquid on one side and in contact with the elongated cooling loop on an opposite side.
A method for cooling servers, comprising:
- submerging one or more servers in an electrically insulating liquid, whereby at least a portion of the heat generated by the one or more servers is transferred to the liquid;
- positioning a heat exchanger in contact with the electrically insulating liquid;
- and
- circulating a coolant in a vertically oriented loop between the heat exchanger and at least one heat sink, wherein the at least one heat sink is the earth,
- wherein the heat exchanger comprises a thermally conductive wall in contact with the electrically insulating liquid on one side and in contact with the vertically oriented loop on an opposite side.
