Abstract
The rotation of axial-flow blades permits air entered through an inlet port to exit directly to outside of a case in the axial direction, and the rotation of centrifugal blades permits air entered through the inlet port to exit through a side surface outlet port to the outside of the case in the centrifugal direction. Accordingly, the amount of flow of air exiting from inside of the case can be increased so that the amount of heat dissipation is increased. It is therefore able to provide a cooling apparatus and electronic equipment mounting the cooling apparatus with improved cooling efficiency while achieving a small thickness.
Claims10
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 to 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;
- a driving part for driving said fan to rotate;
- and
- a radiator structure provided at at least one of said first outlet port or said second outlet port, and further wherein a heat pipe is in contact with at least a portion of the radiator structure and wherein the radiator structure is comprised of at least a plurality of fins each having a particular surface area, the surface area of the individual fins varying across different portions of the heat pipe structure.
Electronic equipment having a cooling apparatus:
- wherein said cooling apparatus is comprised of:
- a fan having axial-flow blades and centrifugal blades;
- a case containing said fan rotatably, and having an inlet port for permitting air to 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;
- a driving part for driving said fan to rotate;
- and
- a radiator structure provided at at least one of said first outlet port or said second outlet port, and further wherein a heat pipe is in contact with at least a portion of the radiator structure and wherein the radiator structure is comprised of at least a plurality of fins each having a particular surface area, the surface area of the individual fins varying across different portions of the heat pipe structure.
