Abstract

A means by which high pressure coolant can be within close proximity to electronic chips so that heat fluxes can be dissipated and yet not transfer the pressure as an excessive load on a chip is shown in 1. The figure illustrates a cooling device containing fins, inner and outer axial fins, and a metal bellows a thickness greater than that required if the bellows to behave elastically like a spring. A multi-chip is encapsulated as discussed below.

Buffered Immersion Cooling With Bellows Providing Barrier Chip and System Coolant and Pressure

       A means by which high pressure coolant can be within close
proximity to electronic chips so that heat fluxes can be dissipated
and yet not transfer the pressure as an excessive load on a chip is
shown in 1.  The figure illustrates a cooling device containing fins,
inner and outer axial fins, and a metal bellows a thickness greater
than that required if the bellows to behave elastically like a
spring.  A multi-chip is encapsulated as discussed below.

      The cooling device shell assemblies (bellows with fin
structure) are attached to the containment such that its closed
protrudes beyond its fully assembled position.  The structure is
depicted in Figs. 2A and 2B.  Radial are located beneath a supply jet
(Fig. 2B), and two of axial fins protrude from an annular tube
attached to base of the bellows (Fig. 2A).  The annular tube has
along its axial length and radially spaced so uniform heat transfer
can be achieved from the axial protruding from the tube.

      Individual cooling regulator rings with holes of diameter for
flow by-pass are placed at locations across the module for customized
 Alternatively, a single cooling regulator ring type can be used
throughout the module if customization not needed or desired.  The
regulator ring controls fluid and distribution within the annular
tube.

      Supply and return coolant chambers are attached and mak...
