Apparatus for temperature control of electronic devices
 The superior thermal conductivity of immersion cooling combined with the service convenience of conduction cooling is provided through the use of unitary thermal transfer replaceable units positioned beneath a refrigeration source. Each unit contains electronic devices in a thermal transfer fluid. The unit construction permits replaceability in service without exposing a central fluid reservoir or opening a refrigerator.
