Abstract

Double stack, force-cooled cold plates, which are used as electronic chassis, are investigated for all conditions of unequal temperature and heat loading. A closed form solution that relates the plate temperatures to composite heat loads is derived. This analysis covers all regimes of operation. In particular, this includes the previously ignored regime in which no adiabatic point exists anywhere on either of the fins 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.
