Fan support
Particular embodiments described herein provide for an electronic device that can be configured to include a fan where the fan blades are decoupled from the center shaft. The fan can include a center shaft, a motor coil support, motor coils coupled to the motor coil support, a rotator coupled to the center shaft, and fan blades coupled to the rotator, where rotation of the fan blades is decoupled from the center shaft by the rotator. A blade support can be coupled to the rotator, where the blade support couples the fan blades to the rotator and magnets can be coupled to the blade support. In an example, the rotator can include an inner, an outer race, and bearings.
1. A fan comprising:
a center shaft;
a motor coil support;
motor coils coupled to the motor coil support;
a rotator coupled to the center shaft, wherein the rotator is between the center shaft and the motor coils; and
fan blades coupled to the rotator, wherein rotation of the fan blades is decoupled from the center shaft by the rotator.
2. The fan of claim 1 , further comprising:
a blade support coupled to the rotator, wherein the blade support couples the fan blades to the rotator; and
magnets coupled to the blade support.
3. The fan of claim 2 , wherein the rotator includes an inner race, bearings, and an outer race, wherein the blade support is coupled to the outer race.
4. The fan of claim 3 , wherein the inner race is coupled to the center shaft.
5. The fan of claim 1 , wherein the center shaft, the motor coil support, and the motor coils are static and do not rotate.
6. The fan of claim 1 , wherein the fan is in a chassis of an electronic device and the center shaft extends from a first side of the chassis towards a second side of the chassis and there is a gap less than about one (1) millimeter between the second side of the chassis and the center shaft.
7. The fan of claim 1 , wherein the fan is located in a laptop computer.
8. An electronic device comprising:
memory;
at least one heat source; and
one or more fans, wherein at least one of the one or more fans includes:
a center shaft;
a motor coil support;
motor coils coupled to the motor coil support;
a rotator coupled to the center shaft, wherein the rotator is between the center shaft and the motor coils; and
fan blades coupled to the rotator, wherein rotation of the fan blades is decoupled from the center shaft by the rotator.
9. The electronic device of claim 8 , wherein the at least one of the one or more fans further includes:
a blade support coupled to the rotator, wherein the blade support couples the fan blades to the rotator; and
magnets coupled to the blade support.
10. The electronic device of claim 9 , wherein the rotator includes an inner race, bearings, and an outer race, wherein the blade support is coupled to the outer race.
11. The electronic device of claim 10 , wherein the inner race is coupled to the center shaft.
12. The electronic device of claim 8 , wherein the center shaft, the motor coil support, and the motor coils are static and do not rotate.
13. The electronic device of claim 8 , wherein the center shaft extends from a first side of a chassis of the electronic device towards a second side of the chassis and there is a gap less than about one (1) millimeter between the second side of the chassis and the center shaft.
14. The electronic device of claim 8 , wherein the at least one heat source is a processor.
15. A method comprising:
receiving data related to thermal properties of at least one heat source; and
activating a fan based on the received data, wherein the fan includes:
a center shaft;
a motor coil support;
motor coils coupled to the motor coil support;
a rotator coupled to the center shaft, wherein the rotator is between the center shaft and the motor coils; and
fan blades coupled to the rotator, wherein rotation of the fan blades is decoupled from the center shaft by the rotator.
16. The method of claim 15 , wherein the fan further includes:
a blade support coupled to the rotator, wherein the blade support couples the fan blades to the rotator; and
magnets coupled to the blade support.
17. The method of claim 16 , wherein the rotator includes an inner race, bearings, and an outer race, wherein the blade support is coupled to the outer race.
18. The method of claim 17 , wherein the inner race is coupled to the center shaft.
19. The method of claim 15 , wherein the center shaft, the motor coil support, and the motor coils are static and do not rotate.
20. The method of claim 15 , wherein the fan is located in a laptop computer.
