Abstract:
1. A method of reducing the fluid loss of a closed loop cooling system, said method comprised of the steps: (A) introducing a supply of liquid coolant from a supply valve to a two-phase cooling chamber; (B) utilizing said supply of liquid coolant to cool an at least one electronic component; (C) removing a portion of said supply of liquid coolant via an outlet port of said two-phase cooling chamber, wherein said outlet port is fluidly connected to a return valve; (D) stopping the operation of said electronic component; (E) stopping the flow of said liquid coolant to said two-phase cooling chamber via said supply valve; (F) allowing a substantial portion of said liquid coolant within said two-phase cooling chamber to flow through said return valve and toward a reservoir; and, (G) after said substantial portion of said liquid coolant is removed from said two-phase cooling chamber, stopping the flow of said liquid coolant between said cooling chamber and said reservoir via said return valve.
