Electronic device with rotatable circuit board

The present invention relates to an electronic device, and more particularly to an electronic device that uses a rotatable circuit board to perform a heat dissipation function.

The internal heat of the electronic device generates heat due to component operation. Therefore, a heat dissipation module is generally provided corresponding to the heat generating component (for example, a central processing unit, a graphics processing unit, etc.) to provide a heat dissipation effect inside the electronic device. Conventionally, the heat dissipation method of the electronic device is mostly performed by a fan or a heat pipe or the like in combination with a heat dissipating fin, and exchanges heat with air or a heat transfer medium.

As the performance of the overall system and the internal processing chip is increased, the heat dissipation requirement is also increased, and it is often necessary to provide a larger fan, a larger area of heat sink fins or a corresponding heat pipe loop configuration, etc., in order to provide better heat dissipation of the device. effectiveness. However, the arrangement of the aforementioned heat dissipating components requires relatively more internal space. For an electronic device with limited internal space, how to properly arrange the components of the internal space is a great test for the design manufacturer. If the arrangement of these heat dissipating components must increase the thickness of the electronic device, and it runs counter to the trend of thinning and thinning of current electronic devices, it will also cause trouble to the manufacturer.

Therefore, how to further improve the conventional design to design an electronic device that can meet the thin and light design and ensure the heat dissipation efficiency of the device is a subject worthy of study.

The main purpose of this creation is to provide an electronic device that performs a heat dissipation function using a rotatable circuit board.

In order to achieve the above object, the electronic device with the rotatable circuit board of the present invention comprises a device body, a rotating module and a main circuit board. The device body includes a power supply module. The rotating module is disposed in the device body. The main circuit board is coupled to the rotating module, so that the main circuit board can be rotated relative to the device body by the rotating module. The main circuit board includes at least one heating element and at least one fin structure, and each fin structure is disposed corresponding to each heating element. When the power supply module is powered to the rotating module, the rotating module drives the main circuit board to perform a rotating operation with respect to the device body to dissipate heat by at least one fin structure in the rotating operation.

Therefore, the electronic device of the present invention can be thermally convected by the rotation of the main circuit board itself and the air inside the device body to generate a high-efficiency heat exchange effect without additionally providing a heat dissipating component such as a fan, thereby effectively reducing the internal space. The use of this design can make the temperature of the whole device evenly distributed, and it is not easy to generate a state in which the local temperature is too high.
