Abstract
An improved precision cooling system for high heat density applications comprises a heat exchanger having more fluid outlet conduits than fluid inlet conduits to optimize the pressure drop across the heat exchanger at a given fluid flow rate. The heat exchanger may be of microchannel or tube fin construction, and the cooling system may utilize single phase or multi-phase pumped or compressed fluids.
Claims23
A cooling system for high density heat loads having an air-to-fluid heat exchanger, the heat exchanger comprising:
- an inlet manifold having a fluid inlet conduit with a predetermined cross-sectional flow area;
- an outlet manifold;
- a first plurality of heat transfer conduits fluidicly coupled between the inlet manifold and the outlet manifold;
- and
- a plurality of fluid outlet conduits coupled to the outlet manifold and having a combined cross-sectional flow area greater than the cross-sectional flow area of the inlet conduit, thereby minimizing pressure drop across the heat exchanger;
- wherein the combined cross-sectional flow area of the plurality of fluid outlet conduits is either maintained or increased over a distance sufficient to permit the minimizing of the pressure drop across the heat exchanger.
