Method of reducing fluid emissions from a global spray cooling system
The present invention uses multiple global cooling chambers for providing liquid cooling to a plurality of electronic components. The global cooling chambers utilize a non-electrically conductive fluid which is in direct contact with the components to be cooled. The system provides very effective heat transfer rates, environmental isolation of the electronics components and can be deployed in a wide range of applications. Multiple global cooling chambers allows for the hot swapping of cards during operation of the system. Valves provide the ability to minimize the amount of interaction between the cooling fluid and air outside the chambers.
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.
2. The method of reducing fluid loss of a closed loop cooling system of claim 1 , wherein an electronic control system controls the actuation of said supply valve.
3. The method of reducing fluid loss of a closed loop cooling system of claim 1 , wherein an electronic control system controls the actuation of said return valve.
4. A method of reducing the interaction between a fluid of a closed loop cooling system and the environment, 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;
(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; and,
(H) after said return valve closes, gaining access to said two-phase cooling chamber by opening a sealed faceplate.
