Thedatafor the natural convection condition has been collected at 0.3 m/s (60 ft/min) of airflow, which is the typical airflow generated by other heatdissipatingcomponentsinmany ofthesystemsthatthesetypesofmodules are used in. In the final system configurations,theairflowrateforthenatural convection condition can vary due to temperature gradients from other heat dissipatingcomponents.
