Abstract:
1. A cooling apparatus comprising: a fan having axial-flow blades and centrifugal blades; a case containing said fan rotatably, and having an inlet port for permitting air enter in an axial direction of rotation from outside by a rotary action of said axial-flow blades under rotation of said fan, a first outlet port, which is disposed opposite to said inlet port, for permitting air entered through said inlet port to exit to said outside in said axial direction, and a second outlet port for permitting air entered through said inlet port to exit to said outside in a centrifugal direction under a rotary action of said centrifugal blades; and a driving part for driving said fan to rotate; wherein said case is a substantially rectangular shape; said second outlet port has a first side surface outlet port provided at a first side surface of said case and a second side surface outlet port provided at a second side surface, which is substantially orthogonal to said first side surface; wherein said cooling apparatus further comprises a first radiator plate provided at said first side surface outlet port and a second radiator plate provided at said second side surface outlet port; wherein said second radiator plate is formed to have a smaller surface area than that of said first radiator plate; said cooling apparatus further comprises a heat transporting body having an endothermic part for absorbing heat by vaporizing working fluid and a radiating part for dissipating heat by condensing said working fluid; wherein said heat transporting body is disosed such that said radiating part contacts with said first radiator plate and a portion closer to said endothermic part than said radiating part is disposed so as to make contact with said second radiator plate.
