1. A cool fluid reservoir comprising:
a cylinder having an internal volume defined between an inlet and an outlet, and a first opening;
a hollow piston slidably connected to the cylinder via one of the inlet or the outlet to split the internal volume into a first volume portion that is filled with a cool fluid and a second volume portion that is filled with a driver fluid; and
a driver fluid assembly comprising a driver pump fluidically coupled to the second volume portion via the first opening, wherein the first opening is formed on a section of the cylinder that corresponds to the second volume portion,
wherein the first volume portion is fluidically connected to a closed fluid loop of a coolant distribution unit (CDU) via the hollow piston and another one of the inlet or the outlet, and wherein the driver pump pumps the driver fluid into the second volume portion via the first opening to slidably drive the hollow piston along a first direction to reduce the first volume portion and inject a portion of the cool fluid from the first volume portion into the closed fluid loop based on an operating pressure of the cool fluid in the closed fluid loop.
