Abstract: Various aspects include devices, systems, and methods for multi-tank immersion cooling distribution. The devices and systems may include a coolant distribution unit, a coolant manifold, a supply and return line, and one or more immersion cooling racks. The coolant distribution unit may be configured to adjust a temperature and pump a fluid used as a coolant. The coolant manifold may redistribute the fluid. The immersion cooling racks may be disposed between the coolant distribution unit and the coolant manifold. Each immersion cooling rack may be coupled to the coolant manifold through an inlet duct for receiving the fluid from the coolant manifold and an outlet duct for returning the fluid to the coolant manifold.
