Modular Jet Impingement Cooling Tank

      Disclosed is a system design for cooling printed circuit
boards.  This design provides a method of cooling high density/power
circuits on large processor and memory boards.  This design uses a
Modular Jet Impingement Cooling Tank (M-JICT).

      The M-JICT is designed to cool large processor boards by
totally immersing the electronic component area of the board in an
inert non-conductive fluid known as "Fluorinert FC-77" (Fig. 1).

      This cooling technique is achieved by allowing the
fluid/coolant to flow directly over the electronic circuits.

      The heat dissipated from these components is removed by the
continuous pumping of coolant through the sealed tank caps and
internal jet orifices (Figs. 2 and 3).

      A pump can provide the cooling required at a low pressure of 3
psi at 60 gallons/minute.  A constant operating temperature of
25ºC can be maintained on each individual electronic
component.  This improves the reliability and maintainability of the
electronic system.  The coolant is constantly being re-circulated to
meet the required temperature range.  The M-JICT contains all the
major operating devices and electronic components and allows a
practical means of expedient system access for input/output and
maintenance requirements.

      The tank cross-section, (Fig. 4) illustrates the sealing
technique using O-ring seals to contain the fluorocarbon fluid,
"Fluorinert FC-77".  The mec...
