Systems and methods for immersion cooling thermal management

An immersion cooling system for thermal management of information technology (IT) components, comprising:

• an immersion tank including a body defining a chamber that receives a cooling fluid,
• a cooling fluid supply loop in communication with chamber of the immersion tank providing the cooling fluid thereto;
• a cooling fluid return loop in communication with the chamber of the immersion tank allowing the cooling fluid to exit the chamber of the immersion tank to facilitate circulation of the cooling fluid therethrough;
• a pump in communication with the cooling fluid return loop and configured to drive circulation of the cooling fluid through the chamber of the immersion tank;
• an IT container that is at least partially received within the chamber of the immersion tank, and includes a body with a plurality of compartments defined therein and each configured to receive one or more IT components, the body of the IT container further includes a plurality of openings defined therein and corresponding to the plurality of compartments to selectively allow the cooling fluid to flow through plurality of compartments, each of the plurality of openings located inside a corresponding compartment of the plurality of compartments;
• a plurality of fluid gates corresponding to the plurality of openings of the body of the IT container, the plurality of fluid gates including one or more portions that are movable between a closed position preventing the cooling fluid from passing through the plurality of openings, and an open position that allows the cooling fluid to pass through the plurality of openings and through the plurality of compartments;
• and
• a control system in communication with the pump, the control system including a fluid level sensor positioned to gather information related to a fluid level of the cooling fluid in the chamber of the immersion tank, and a plurality of pressure sensors positioned along the plurality of compartments to gather information related to a fluid pressure of the cooling fluid in the plurality of compartments, the control system is configured to control the pump to alter flow of the cooling fluid based the fluid level of the cooling fluid in the chamber of the immersion tank or the fluid pressure in the plurality of compartments.

A method for thermal management of IT components, comprising:

• circulating, using a pump, a cooling fluid though a chamber of an immersion tank;
• providing one or more IT components to at least one compartment of an IT container that is received within an immersion tank;
• upon providing the one or more IT components to the at least one compartment of the IT container, opening one or more fluid gates of a corresponding plurality of openings to selectively allow the cooling fluid to flow from the chamber of the immersion tank into the at least one compartment of the IT container and flow out of the at least one compartment, the corresponding plurality of openings located inside the at least one compartment, the one or more fluid gates including one or more portions that are movable between a closed position preventing the cooling fluid from passing through the plurality of openings, and an open position that allows the cooling fluid to pass through the plurality of openings and through the plurality of compartments;
• gathering, using one or more sensors, information related to a fluid level of the cooling fluid in the chamber of the immersion tank;
• gathering, using one or more sensors, information related to a fluid pressure of the cooling fluid in the at least one compartment of the IT container,
• controlling the pump to circulate the cooling fluid through the chamber of the immersion container and the at least one compartment of the IT container such that the fluid level or the fluid pressure is substantially constant.
