Patent ID: 7836748

Claim:
A method, comprising: providing a test fluid into a chamber associated with a cooling system for an electronic integrated circuit; partially inserting a valve a first distance into an opening of the chamber to seal the opening of the chamber, the opening having a width, wherein said valve defines an axis along which the valve is inserted into the opening, and further wherein said valve includes a first sealing portion to seal the opening of the chamber when the valve is inserted the first distance; continuing to insert the valve an intermediate distance, between the first distance and a second distance, to unseal the chamber, wherein said valve includes a second sealing portion on the valve, offset from the first sealing portion along the axis, to seal the chamber at the opening when the valve is inserted the second distance, and further wherein said valve defines a passage between the first and second sealing portions, at least some the passage having a width less than the first and second sealing portions to permit a flow of the test fluid when the valve is inserted the intermediate distance; evacuating the test fluid from the unsealed chamber while the valve is inserted the intermediate distance; filling the unsealed chamber with a coolant fluid while the valve is inserted the intermediate distance; and continuing to insert the valve from the intermediate distance to the second distance to reseal the opening of the chamber with the second portion of said valve.
