Abstract
A hybrid cooling approach uses both conduction and convection cooling for circuit cards. The hybrid cooling approach also isolates sensitive circuitry in the circuit cards from the ambient environment. The hybrid cooling approach uses an electronic module with a heat spreader. The heat spreader is coupled to the circuit card. The heat spreader defines openings disposed at an opposite end of a connector. The openings permit a fluid to flow within a cavity defined by the heat spreader.
