Patent Application
20160309615
This application claims priority to Chinese Patent Application No. 201510174449.4, filed on Apr. 14, 2015 the contents of which are incorporated by reference herein.
The subject matter herein relates to electronic devices, especially relates to a electronic devices with a fan for dissipating heat generated by the electronic device during operation.
Electronic devices, for example computers, generate heat during operation. The electronic device includes a fan to dissipate the heat. The fan rotates at a single direction increasing the temperature of the air outlet.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
The electronic device 10 further includes cooling fins 60. The cooling fins 60 are positioned on the thermal element 30. The fan 50 is positioned on the cooling fins 60. The thermal element is a central processing unit electrically connected to the motherboard 70 of the electronic device 10. The controller 40 electrically connects to the motherboard 70. The first air outlet 22 is opposite to the second air outlet 24. The first air current and the second air current are flowing in opposite directions.
In one embodiment, the controller 40 controls the fan 50 to periodically rotate clockwise and anticlockwise. When an anticlockwise rotation time of the fan 50 reaches a first preset time, the controller 40 controls the fan 50 to rotate clockwise to generate the first air current to dissipate the heat generated by the thermal element 30 out of the first air outlet 22. When a clockwise rotation time of the fan 50 reaches a second preset time, the controller 40 controls the fan 50 to rotate anticlockwise to generate the second air current to dissipate the heat generated by the thermal element 30 out of the second air outlet 24. The controller 40 further controls the fan 50 to rotate clockwise when the electronic device 10 starts to work. In an embodiment, the thermal element 30 is closer to the first air outlet 22; the first preset time is greater than the second preset time. In another embodiment, the first preset time is equal to the second preset time.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
