The second side plate assembly 23 includes four side plates arranged corresponding to the four sides of the mounting plate 22. The second side plate assembly 23 can make the bracket 20 have a certain thickness, improve the structural strength, and reduce the deformation of the bracket 20 due to the weight of the fan 40. Bolt holes or a clamping structure can be set on the mounting plate 22 to connect with the fan 40.

[0053] like Figures 1 to 4 As shown, in some embodiments of the present invention, the connecting member 31 also includes a third connecting plate 34, which is connected to the end of the first connecting plate 32 away from the opening 111 along the direction away from the opening 111, that is, along the depth direction of the accommodating cavity 11, and the third connecting plate 34 is used to be connected to the second side panel assembly 23 through fasteners.

[0054] It can be understood that the third connecting plate 34 is arranged on one side of the first connecting plate 32 along the length direction of the shell 10, and the third connecting plate 34 is connected to the end of the first connecting plate 32 away from the opening 111. The third connecting plate 34 can limit the sliding direction of the bracket 20. Bolt holes are provided on the third connecting plate 34, and bolt holes are also provided at corresponding positions on the bracket 20, so that the bracket 20 and the third connecting plate 34 can be connected by bolts, thereby further improving the reliability of the connection.

[0055] Specifically, a notch 25 is further provided on the second side panel assembly 23, and the notch 25 is coaxially arranged with the bolt hole on the third connecting plate 34, so that when installing the fastener, for example, when tightening the bolt, the screwdriver can pass through the notch 25 and extend into the bolt hole of the side panel assembly to tighten the bolt to connect the side panel assembly and the third connecting plate 34, making the operation more convenient.

[0056] like Figures 1 to 4 As shown, in some embodiments of the present invention, the connecting member 31 also includes a fourth connecting plate 35, and along the direction toward the opening 111, that is, along the depth direction of the accommodating cavity 11, the fourth connecting plate 35 is connected to one end of the first connecting plate 32 close to the opening 111, and the bracket 20 also includes an extension portion 26, the extension portion 26 protrudes from the outer surface of the second side plate assembly 23, and the fourth connecting plate 35 is used to be connected to the extension portion 26 through a fastener.

[0057] The fourth connecting plate 35 and the fifth connecting plate 36 are arranged on the other side of the first connecting plate 32.
