Abstract:
An EMI shielding fluid control apparatus for controlling the coolant flow between a spray plate and a printed circuit board carrying at least one component to be cooled, the EMI shielding fluid control apparatus comprising:(A) a spray plate;(B) at least one atomizer, carried by the spray plate;(C) a printed circuit board;(D) a shroud having a sidewall defining a spray cavity sized to enclose at least one generally conical spray of coolant mist discharged by at least one atomizer defined on a surface of the spray plate;(E) inlet passage means, in communication with the spray cavity, for allowing vapor to enter the spray cavity for movement in a direction following the spray of coolant mist;(F) effluent passage means, in communication with the spray cavity, for allowing vapor and coolant to leave the spray cavity;(G) fastening means for maintaining the shroud in a position between the spray plate and printed circuit board adjacent to the at least one component to be cooled; and(H) an EMI shield means, carried by the shroud, for preventing EMI passage but for allowing coolant passage.
