External Thermo Electric Cooler Integrated Circuit Package

      Described is an external thermo electric cooler (TEC)
integrated circuit (IC) package designed to maintain a maximum
operating temperature of 25oC so that a given IC module will operate
approximately twenty percent faster.

      The TEC IC package is designed to optimize the cooling of an IC
module to 25oC, or lower, and to optimize the efficiency of the TEC
cooling pump.  In addition, the package is designed to reject any
shunting effects across the pump, to reject a tendency for the pump
to have water condense on it, and to minimize any "passive" heat
load. Also, the pump is designed to be reliable and reworkable.

      The figure shows a cross sectional/side view of the package
which consists of TEC unit 10, IC module 11 and heat sink 12.  TEC
unit 10 is mounted in the center of the package, on top of IC module
11, and consists of cold side plate 13, hot side plate 14 and heat
pump collar 15.  IC module 11 is positioned next to cold side plate
13, while heat sink 12 is positioned next to hot side plate 14.  Heat
pump collar 15 surrounds the package and provides four functions:
   (1) It is a mechanical mechanism by which heat sink 12 and TEC
unit 10 house IC module 11.
     (2) It serves as a stabilizer so that heat sink 12 cannot be
twist        ed relative to TEC unit 10.
   (3) It acts as a thermal insulator so that the heat from the
surrounding air does not heat up the c...
