ABSTRACT:
A multi-fluid cooling system and method for cooling an electronic device are provided which employ freeze protection when in a shipping state. The cooling system includes a coolant loop having an expansion tank containing first and second fluids, which are immiscible and of different densities, and the second fluid freezes at a lower temperature than the first. The coolant loop further includes a first valve for facilitating coupling of the first fluid into the coolant loop and a second valve for facilitating coupling of the second fluid into the coolant loop, the first and second valves being independently controllable. Control logic electronically controls actuation of the first and second valves to automatically pass the first fluid through the coolant loop when the system is in an operational state and to automatically maintain the second fluid in the coolant loop when the system is in a shipping state.
