Patent ID: 8182095

Claim:
A heat generating spot cooling method for an apparatus for cooling a heat generating spot of an electronic device which comprises a plurality of components which are disposed side by side to have the same in-plane direction, said components including heat generating spots within surfaces thereof, the apparatus comprising: a first air cooling unit for feeding an air stream to said heat generating spot in an orientation of the in-plane direction; and a second air cooling unit for feeding an air stream to said heat generating spot in said in-plane direction in a different orientation from the air stream by said first air cooling unit, said method comprising: feeding a first air stream by said first air cooling unit for said components of said electronic device in a first direction in the gaps between opposing surfaces of said components; and feeding a second air stream by said second air cooling unit in a second direction different from the first direction in the gaps between opposing surfaces of said components; and causing said first air stream and said second air stream to collide with each other near central positions of heat generating spots on opposing surfaces of said components, thereby generating evolutional flows which go perpendicularly to one or both of the opposing surfaces of said components.
