The terms used in this specification in the description of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0022] Please refer to Figure 1 , this application provides an embodiment of an electronic device 1000. The electronic device 1000 includes a heat dissipation device 100, an upper shell 200, a lower shell 300, a power component and a support step 400. The lower shell 300 and the upper shell 200 jointly enclose a receiving space. The heat dissipation device 100, the power component and the support step 400 are arranged in the receiving space 1000a. The upper shell 200 is provided with upper air holes, and the lower shell 300 is provided with lower air holes. The lower air holes correspond to the heat dissipation device 100. The support step 400 is fixed to the lower shell 300. When the electronic device 1000 works, the power component generates heat and transfers it to the gas in the receiving space 1000a. The heat dissipation device 100 can drive the gas in the receiving space 1000a to move, so that the external gas enters the receiving space 1000a from the upper air holes, and then is discharged to the outside from the lower air holes. Furthermore, the gas in the receiving space 1000a exchanges heat with the gas in the external environment, thereby realizing heat dissipation.

[0023] In some embodiments, the support step 400 and the lower shell 300 are integrally formed.

[0024] This application provides an embodiment of a heat dissipation device 100. The heat dissipation device 100 includes an upper cover 10, side plates 20, a fan 30, and support columns 40, as Figure 2 shown. The upper cover 10 is fixed to the upper shell 200 of the electronic device 1000 by bolts 50. The side plates 20 are fixed to the upper cover 10. The upper cover 10 and the side plates 20 jointly enclose an air inlet, an air outlet, and an installation space 100a. Both the air inlet and the air outlet communicate with the installation space 100a. The side plates 20 are used to abut against the support step 400 of the electronic device 1000. The fan 30 is located in the installation space 100a, and the fan 30 is fixed to the upper cover 10. One end of the support column 40 is connected to the upper cover 10. The end of the support column 40 away from the upper cover 10 protrudes from the side plates 20, and the end of the support column 40 away from the upper cover 10 is used to abut against the lower shell 300 of the electronic device 1000. The projection of the lower shell 300 in the direction of the fan 30 is exposed to view, and the support step 400 has a lifting effect on the side plates 20, so that the deformation space between the fan 30 and the lower shell 300 of the electronic device 1000 is increased. When the user clamps the electronic device 1000, the lower shell 300 elastically deforms in the direction of the fan 30, and the increase in the distance between the lower shell 300 and the fan 30 can reduce the risk of contact between the lower shell 300 and the fan 30. In addition, the support column 40 can resist the elastic deformation of the lower shell 300 of the electronic device 1000 towards the upper shell 200 and the lower shell 300 towards the upper shell 200, reduce the elastic deformation of the lower shell 300 in the direction of the fan 30, further reduce the risk of contact between the lower shell 300 and the fan 30, reduce abnormal noises emitted by the fan 30, and improve the user experience.

[0025] In some embodiments, a limiting notch 400a is provided at one end of the support step 400 away from the lower shell 300, as Figure 2 shown. The side plates 20 abut against the limiting notch 400a to realize the support of the support step 400 on the side plates 20.

[0026] In some embodiments, the shape of the support step 400 is arc-shaped, and the limiting notch 400a is provided on the inner side of the support step 400. The side plates 20 abut against the limiting notch 400a, allowing the side plates 20 to move along the vertical direction y, but not allowing the side plates 20 to move along the horizontal direction x, so as to limit the side plates 20 and reduce the deviation of the side plates 20. It should be noted that the vertical direction y is the same as the direction of the lower shell 300 towards the fan 30.

[0027] In some embodiments, in order to stably fix the support step 400 to the lower shell 300, through holes are provided on the support step 400, and screw holes are provided on the lower shell 300. Bolts are passed through the through holes and screwed into the screw holes, thereby increasing the stability of the support step 400.

[0028] For the above-mentioned fan 30, the fan 30 includes a driving member and blades. The driving member is fixed to the upper cover 10, and the blades are rotatably connected to the driving member. When the electronic device 1000 operates, the driving member drives the blades to rotate, and the blades rotate relative to the driving member, thereby realizing the movement of the gas in the accommodation space 1000a. In some embodiments, the number of the support columns 40 is several, and the several support columns 40 are arranged at intervals along the circumferential direction of the fan 30.

[0029] In the embodiment of the present application, when the side plate 20 abuts against the support step 400 of the electronic device 1000, the support step 400 of the electronic device 1000 has a lifting effect on the side plate 20, and the projection of the lower shell 300 of the electronic device 1000 in the direction of the fan 30 is exposed to the view, so that the deformation space between the fan 30 and the lower shell 300 of the electronic device 1000 is increased. When the user clamps the electronic device 1000, the support columns 40 can resist the elastic deformation of the lower shell 300 of the electronic device 1000 towards the upper shell 200 and the lower shell 300 towards the upper shell 200, reducing the risk of contact between the lower cover and the fan 30, thereby solving the problem of abnormal noise generated by the fan 30 and enhancing the user experience. In addition, compared with the traditional technical solution, the lower cover mentioned in the background art is cancelled in the present application. Therefore, the distance between the lower shell 300 and the upper shell 200 of the electronic device 1000 can be reduced, and the thickness of the electronic device 1000 is decreased, realizing the thin and light of the electronic device 1000.
