Multi-Rack Immersion Cooling Distribution System

A system for controlling temperature in an immersion cooling system, comprising:

• A tank configured to contain a coolant fluid;
• a coolant distribution unit configured to pump the coolant fluid;
• a coolant manifold for redistributing the coolant fluid;
• a supply line coupled to the coolant distribution unit and the coolant manifold, wherein the supply line is configured to convey the coolant fluid from the coolant distribution unit to the coolant manifold;
• a return line coupled to the coolant distribution unit and the coolant manifold, wherein the return line is configured to convey the coolant fluid from the coolant manifold to the coolant distribution unit;
• and
• a plurality of servers disposed between the coolant distribution unit and the coolant manifold, wherein each server is coupled to the coolant manifold through a first inlet duct for receiving the coolant fluid from the coolant manifold.

A system for controlling temperature in an immersion cooling system with a single coolant distribution system, comprising:

• a component coolant tank configured to hold at least one electronic component at least partially submerged in a coolant fluid pumped into the component coolant tank;
• a buffer coolant tank;
• and
• a weir extending along an upper edge of a barrier separating the component coolant tank from the buffer coolant tank, wherein the weir is configured to allow excess coolant fluid from the component coolant tank to spill out of the component coolant tank, over the weir, and into the buffer coolant tank.
