Claim 0:
1. An electronic component heat dissipation apparatus comprising:
a heat dissipation housing having an external wall and an internal wall defining outer chamber therebetween, the internal wall defining internal chamber having an airflow inlet opening and an airflow outlet opening,
the heat dissipation housing being aligned with at least one electronic component so as to define a thermal chimney through the internal chamber for the flow of heated air,
the external wall having at least one external air opening configured to allow external air into the outer chamber,
the internal wall having a plurality of heat dissipation nozzles, each heat dissipation nozzle having an external air inlet opening having an inlet diameter (Id) located within the internal wall and an external air outlet opening having an outlet diameter (Od) located within the internal chamber, the inlet diameter being greater than the outlet diameter,
whereby external air is pushed and/or pulled through the plurality of heat dissipation nozzles from the outer chamber into the internal chamber at an increasing velocity from the outer chamber into the internal chamber and mixing with the flow of heated air thereby increasing the velocity of the flow of heated air though the internal chamber.
