Claim 8:
9. An electronic component heat dissipation apparatus comprising:
a heat dissipation housing being aligned with at least one electronic component so as to define a thermal chimney for the flow of heated air, the housing having a wall having a plurality of heat dissipation nozzles,
each heat dissipation nozzle having an air inlet opening located within the wall and an air outlet opening located within the thermal chimney, the diameter of the air inlet opening being greater than the diameter of the air outlet opening,
whereby air is pulled through the plurality of heat dissipation nozzles into the thermal chimney at an increasing velocity and mixing with the flow of heated air thereby increasing the velocity of the flow of heated air though the thermal chimney.
