Abstract

The invention relates to an electronic device which comprises a lower shell, and the lower shell comprises an opening. The electronic device also comprises a heat radiating device, a temperature detection unit, a processing unit and a driving device, and the heat radiating device is arranged at the opening of the lower shell and comprises a frame, a screw rod, a guide rod and a plurality of heat radiating fins, wherein the frame comprises a first supporting wall and a second supporting wall; the screw rod comprises a spiral groove, and the screw rod and the guide rod are arranged between the first supporting wall and the second supporting wall; the heat radiating fins are partially clamped in the spiral groove of the screw rod, and each heat radiating fin comprises a through hole; and the guide rod penetrates through the through hole of each heat radiating fin. When the internal temperature of the electronic device, which is detected by the temperature detection unit, is lower than the preset value, the processing unit controls the driving device to drive the screw rod to rotate reversely, and the heat radiating fins are driven to move until getting closer to each other. By adopting the electronic device, the distance between every two heat radiating fins can be adjusted automatically.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device for automatically adjusting the distance between heat sinks. Background technique [0002] At present, the integration degree of some electronic devices is getting higher and higher, and the volume is getting smaller and smaller, such as portable computers. Usually, for heat dissipation, a fixed exhaust channel is provided on the bottom or side of the electronic device. However, these fixed exhaust channels will enter some dust when there is no need to dissipate heat, which will affect the performance of the electronic device. At the same time, these fixed exhaust channels will also affect the appearance of the electronic device. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device that can automatically adjust the distance between the heat sinks. [0004] An electronic device includes a lower case, the lower case inc...
