Abstract

A gantry crane for attachment to an immersion cooling system includes rails attachable to a tank of the immersion cooling system. The gantry also includes a collapsible frame configured to travel along the rails. A connector is adapted for connecting to a computer hardware component intended to be cooled in the immersion cooling system, and the gantry includes a winch mounted to the frame and configured to raise and lower the connector.

Claims (27)

1 . A gantry crane for attachment to an immersion cooling system, the gantry crane comprising:

rails attachable to a tank;

a collapsible frame configured to travel along the rails;

a connector adapted for connecting to a computer hardware component; and

a winch mounted to the frame and configured to raise and lower the connector,

wherein the frame comprises two supports,

an upper beam to which both of the supports are connected and extending along a first longitudinal axis, and a lower beam that hangs from the upper beam, the lower beam extending between a first end and a second end along a second longitudinal axis parallel to the first longitudinal axis,

wherein the winch is configured to raise and lower the lower beam relative to the upper beam, and

wherein the connector is configured to move along the lower-bridge beam along the second longitudinal axis between the first end and the second end.

2 . The gantry crane of claim 1 , wherein the connector is a bracket.

3 . The gantry crane of claim 1 , wherein the connector is a pair of jaws.

4 . The gantry crane of claim 1 , wherein the rails are extendable.

5 . The gantry crane of claim 1 , wherein each of the rails includes a fixed track, and the frame includes a movable track for each fixed track, and each movable track is movably connected to a respective one of the fixed tracks.

6 . The gantry crane of claim 1 , wherein the connector is connected to the lower beam.

7 . A gantry crane for attachment to an immersion cooling system, the gantry crane comprising:

rails attachable to a tank;

a collapsible frame configured to travel along the rails;

a connector adapted for connecting to a computer hardware component; and

a winch mounted to the frame and configured to raise and lower the connector,

wherein the frame comprises a first support, a second support, a first hinge, a second hinge, and a bridge, the first support comprising a first lower end and the second support comprising a second lower end, and

wherein the first support is pivotably directly connected to the bridge via the first hinge and the second support is pivotably directly connected to the bridge via the second hinge at a different location such that at least one of the first lower end and the second lower end is configured to be rotated closer to the bridge, and the connector hangs directly from the bridge.

8 . The gantry crane of claim 7 , wherein the connector is movable along the bridge.

9 . The gantry crane of claim 8 , wherein the connector is movable along the bridge in a first direction that is perpendicular to a second direction in which the frame may travel along the rails.

10 . The gantry crane of claim 7 , wherein the supports each include a first end pivotably connected to the bridge and a second end that is opposite the first end and configured to travel along one of the rails.

11 . The gantry crane of claim 10 , wherein each second end is connected to a respective one of the rails.

12 . The gantry crane of claim 7 , comprising a bar extending between the bridge and one of the supports.

13 . The gantry crane of claim 12 , wherein the bar is collapsible.
