Spray chamber valve control system
A spray chamber valve control system for ensuring that coolant is sufficiently available at the intakes of pumps in a spray cooled environment regardless of the attitude, acceleration or deceleration of a spray chassis. The spray chamber valve control system includes a spray chassis with an interior portion for spray cooling electronic devices, a plurality of valves positioned within the inner corners of the spray chassis, and a control unit in communication with the valves for controlling the operation thereof. The control unit ensures that at least one valve is open at all times. The control unit also provides a recovery routine for when only one valve is open during a valve state change.
1. A method of operating a plurality of valves in a spray chamber, said method comprising the steps of:
determining fluid presence at one or more of said valves;
opening one or more of said valves that have fluid present;
activating a pump fluidly connected to said valves; and
determining if a state change is required of any of said valves and executing said state changes if at least two valves are open;
executing a one valve open recovery routine when if a state change is required to open a second valve and only a first valve is currently open, wherein said one valve open recovery routine is comprised of the following steps:
deactivating said pump;
opening said second valve after a delay time; and
reactivating said pump.
2. The method of operating a plurality of valves in a spray chamber of claim 1 , including the step of performing a routine valve scheduler routine upon said valves for maintaining said valves in their respective desired state.
3. The method of operating a plurality of valves in a spray chamber of claim 1 , wherein said routine valve scheduler routine is comprised of the steps of:
(a) energizing a first valve to an appropriate state; and
(b) repeating step (a) for a next valve.
4. The method of operating a plurality of valves in a spray chamber of claim 1 , wherein said routine valve scheduler routine is comprised of the steps of:
(a) energizing a first valve to an appropriate state; and
(b) repeating step (a) for a next valve after a time period.
5. A method of operating a plurality of valves in a spray chamber, said method comprising the steps of:
providing a spray chamber having a plurality of valves, a spray unit, a pump fluidly connected to said spray unit providing a pressurized fluid and a heat producing device;
spraying said heat producing device with said pressurized fluid dispensed from said spray unit;
determining fluid presence at one or more of said valves;
opening one or more of said valves that have fluid present; and
determining if a state change is required of any of said valves and executing said state changes if at least two valves are open.
6. The method of operating a plurality of valves in a spray chamber of claim 5 , including the step of executing a one valve open recovery routine when if a state change is required to open a second valve and only a first valve is currently open.
7. The method of operating a plurality of valves in a spray chamber of claim 6 , wherein said one valve open recovery routine is comprised of the following steps:
deactivating said pump;
opening said second valve after a delay time; and
reactivating said pump.
8. The method of operating a plurality of valves in a spray chamber of claim 5 , including the step of performing a routine valve scheduler routine upon said valves for maintaining said valves in their respective desired state.
9. The method of operating a plurality of valves in a spray chamber of claim 8 , wherein said routine valve scheduler routine is comprised of the steps of:
(a) energizing a first valve to an appropriate state; and
(b) repeating step (a) for a next valve.
10. The method of operating a plurality of valves in a spray chamber of claim 8 , wherein said routine valve scheduler routine is comprised of the steps of:
(a) energizing a first valve to an appropriate state; and
(b) repeating step (a) for a next valve after a time period.
