[0027] Please refer to Figure 1 and Figure 2 The present application provides an electronic device, which may refer to multiple types, such as a computer, a server, or a workstation.

[0028] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides an electronic device, which includes a base 1, an electronic accessory 2 and a radiator 3. The base 1 has a bearing surface 11; the electronic accessory 2 is supported on the bearing surface 11; the radiator 3 has an angle between its extension direction and the direction b of the bearing surface; the first part 31 of the radiator and the electronic accessory 2 are arranged along the extension direction of the bearing surface 11, and are rotatably connected to the bearing surface 11, so that the second part 32 of the radiator swings relative to the first part, and the axial direction of the swing is the direction b of the bearing surface, so that the radiator 3 has a first posture and a second posture; in the first posture, the second part 32 of the radiator is aligned with the electronic accessory 2 along the direction b of the bearing surface; in the second posture, the second part 32 of the radiator and the electronic accessory 2 are arranged along the extension direction of the bearing surface 11.

[0029] In the electronic device provided by the present application, the first part 31 of the radiator is rotatably connected to the bearing surface 11, so that the radiator 3 can switch from the first posture to the second posture. In the second posture, the second part 32 of the radiator and the electronic accessory 2 are arranged along the extension direction of the bearing surface 11, that is, the electronic accessory 2 is avoided in the direction b of the bearing surface, so that the electronic accessory 2 can be smoothly removed from the bearing surface 11. That is, when it is necessary to remove the electronic accessory 2, the radiator 3 can be rotated relative to the bearing surface 11 to remove the shielding of the electronic accessory 2 by the radiator 3, and the electronic accessory 2 can be removed without removing the radiator 3 from the base 1, and the disassembly process is relatively convenient.

[0030] The radiator 3 in the embodiment of the present application is used to dissipate heat for the heating element 9. The heating element 9 can be a central processing unit or a graphics processing unit, etc. The radiator 3 can be a water-cooled radiator 3, or an air-cooled radiator 3, etc. Exemplarily, the radiator 3 is a heat dissipation fin. It can be understood that the radiator 3 generally requires a larger volume to obtain a sufficient heat dissipation area. The larger volume requires the radiator 3 to extend a longer distance in the extension direction of the bearing surface 11, which is easy to block the electronic accessories 2 on the bearing surface 11. In this way, it is difficult to disassemble the electronic accessories 2. In the related art, the radiator 3 needs to be removed before disassembling the electronic accessories 2 to cancel the radiator 3 blocking the electronic accessories 2, and the disassembly of the electronic accessories 2 is more troublesome. Moreover, for water-cooled heat dissipation, it is easy to damage the water-cooling pipe connected to the radiator 3 during the disassembly of the radiator 3. However, the present application does not need to remove the radiator 3 from the bearing surface 11, but only needs to rotate the radiator 3, and the disassembly process is more convenient.

[0031] It can be understood that, in the embodiment of the present application, when in the first posture, along the direction b of the bearing surface, the electronic accessory 2 is located between the second portion 32 of the radiator and the bearing surface 11 .

[0032] In some embodiments of the present application, the base 1 may refer to a circuit board, and the electronic accessory 2 is mounted on the circuit board. For example, the electronic accessory 2 may be a disk, a memory stick, a processor, or the like.

In this structural form, the guide groove 4212 extends along the second arc path, which is conducive to further improving the stability of the heat sink 3 during the rotation process relative to the mounting bracket 4.

[0044] Please refer to Figure 3 and Figure 4In some embodiments of the present application, the direction of the mounting hole 4211 pointing to the guide slot 4212 is radially outward along the central axis of the extension path of the mounting hole 4211.

[0045] Please refer to Figure 5 and Figure 6 In some embodiments of the present application, the electronic device further includes a stopper 6, which is detachably disposed on the mounting bracket 4.

Such a structural form can improve safety. When the electronic accessory 2 needs to be disassembled, the first fastener needs to be removed first, and then the heat sink 3 is rotated. When the first fastener is removed, the first fastener is separated from the detection member 7, and the power is cut off in this case, that is, the power is automatically cut off before the electronic accessory 2 is disassembled, which is conducive to improving the installability.

[0049] In some embodiments of this application, please refer to Figure 5 , the first fastener abuts against the detection member 7 along the axial direction. In this way, it is beneficial to make the first fastener and the detection member 7 contact firmly.
