Claim 9:
10. An electronic component heat dissipation apparatus comprising:
a heat dissipation housing having a wall defining a chamber having at least one airflow inlet opening and an airflow outlet opening, the housing being aligned with at least one electronic component so as to define a thermal chimney through the chamber for the flow of heated air, the wall having a plurality of heat dissipation nozzles, each heat dissipation nozzle having an air inlet opening having an inlet diameter (Id) located within the wall and an air outlet opening having an outlet diameter (Od) located within the chamber, the inlet diameter being greater than the outlet diameter; and
a wind vane rotationally secured to the heat dissipation housing, the wind vane having a venturi tube and an airflow passage, the venturi tube having inlet section, a diverging diffuser section, and a throat section having an airflow inlet, the airflow passage being in direct communication with the venturi tube airflow inlet and heat dissipation housing airflow outlet to allow passage of the flow of heated air from the heat dissipation housing through the venturi tube.
