Abstract: An electrical component having a hybrid air cooling system. The electrical component comprises an air plenum that extends across the width of the component and a first set of air movers that is positionable in a first lateral position downstream of the air plenum within the component enclosure and a second set of air movers that is positionable in a second lateral position downstream of the air plenum within the component enclosure. The first and second sets of air movers each include at least two air movers arranged adjacent each other in series. When both positioned in the component enclosure, the first and second sets of air movers are arranged in parallel such that both serial and parallel air flows are provided within the component enclosure to dissipate heat generated therein.

Abstract: Method and system for shielding a circuit board from electrostatic discharge and from mechanical damage. A circuit board shield of dimensions roughly equivalent to those of the circuit board that the circuit board shield is designed to protect is manufactured to contain apertures complementary in shape, size, and position to heat-producing components affixed to the surface of a circuit board. When the circuit board shield is placed on top of the circuit board, the heat-producing components of the circuit board remain exposed to an external environment via the apertures, while other parts of the circuit board are protected from electrostatic discharge and mechanical damage by the overlying circuit board shield.
