PERFORMANCE ANALYSIS OF DOUBLE STACK COLD PLATES COVERING ALL CONDITIONS OF ASYMMETRIC HEAT LOADING

Double stack, force-cooled cold plates, which are used as electronic c hassis, are investigated for all conditions of unequal temperature and heat loading. A closed form solution that relates the plate temperatu res to composite heat loads is derived. This analysis covers all regim es of operation. In particular, this includes the previously ignored r egime in which no adiabatic point exists anywhere on either of the fin s connecting cover and splitter plates, The heat dissipating advantage of the double stack structure, over a similarly designed single stack structure, is predicted with the analysis presented in the paper.
