Patent ID: 7403385

Claim:
A unit comprising: a printed circuit board having at least one component having a thermal load; and an air control device generally parallel to the printed circuit board, the air control device disposed between an intake opening and an exhaust opening to direct air from low impedance airflow pathways and having at least one air passage aperture positioned relative to the at least one component having the thermal load for directing a flow of air from the intake opening disposed in proximity to a first side of the air control device to the exhaust opening disposed in proximity to a second side of the air control device, the second side of the air control device opposing the first side of the air control device and the air flowing in proximity to the at least one component having the thermal load thus cooling the at least one component with the thermal load, the at least one air passage aperture spaced and sized based on the location of the at least one component having a thermal load located on the printed circuit board; wherein: the air control device comprises a component engaging portion extending from the air control device and into a local circuit board space defined by the air control device and the printed circuit board, the component engaging portion disposed in proximity to the at least one air passage aperture and in thermal communication with the at least one component having the thermal load; and the air control device is formed of high thermal conductivity material configured to (i) receive heat from the at least one component having the thermal load, via the component engaging portion and (ii) dissipate the received heat.
