[0004] 1. Integrated aluminum profile, aluminum profile shell or panel with holes, i.e. air cooling;
[0005] 2. Integrated aluminum profile is divided into two aluminum profiles (or multiple, even add other structure types), and circuit board is pressed in the middle to ensure that aluminum profile directly or indirectly presses the chip on circuit board that needs to be cooled, i.e. cold conduction.
[0006] The disadvantage of the above method 1 is that it needs to be additionally drilled, which is labor-intensive and has poor heat dissipation effect; The disadvantage of method 2 is that the assembly is complex, the shell parts are more, and even multiple aluminum profile molds are needed.

[0015] The vertical strips are vertically arranged, one end of each vertical strip is connected to the upper wall of the box body, and the horizontal strips are perpendicularly connected to the other end of each vertical strip.
[0016] The tray is installed between the two sliding strips.
[0017] By adopting the technical scheme, the tray is installed on the box body in a sliding manner, and the horizontal strips on the two sliding strips lift the tray, so that the tray is attached to the upper inner wall of the box body.
[0018] Optionally, the vertical strips on the two sliding strips are in contact with the two sides of the tray.
[0019] By adopting the technical scheme, the vertical strips on the two sliding strips limit the two sides of the tray, so that the tray cannot shake left and right on the box body.

Mounting strips 11 are protrusively arranged on the inner walls of both sides of the box body 1, and the mounting strips 11 are arranged along the front-rear direction of the box body 1, and through holes or blind holes are formed in the mounting strips 11 and are tapped at both ends, and the front and rear panels are mounted on the box body 1 by screwing screws into the holes.
[0040] Referring to Figure 2 、 Figure 3 Two slide strips 12 are protrusively arranged on the upper inner wall of the box body 1, and the slide strips 12 are L-shaped as a whole, comprising vertical strips 121 and horizontal strips 122. The vertical strips 121 are vertically arranged, and one end is connected to the upper wall of the box body 1, and the horizontal strips 122 are perpendicularly connected to the other end of the vertical strips 121. The two slide strips 12 are arranged at intervals, and the horizontal strips 122 on the two slide strips 12 are arranged between the two vertical strips 121.
[0041] The tray 2 is mounted on the box body 1, and the tray 2 is mounted on the slide strips 12, and the tray 2 is mounted between the two slide strips 12, and the horizontal strips 122 on the two slide strips 12 lift the tray 2, so that the tray 2 is attached to the upper inner wall of the box body 1. The vertical strips 121 on the two slide strips 12 limit the two sides of the tray 2, so that the tray 2 cannot shake left and right when it is on the box body 1. In addition, a fixing screw 13 is threaded through the box body 1, and the fixing screw 13 is threaded into the tray 2 to reinforce the tray 2, prevent the tray 2 from shaking on the box body 1, and ensure that the tray and the box body are in contact to ensure the heat dissipation effect.
[0042] Referring to Figure 3 、 Figure 4 A circuit board 3 is mounted on the tray 2, and the circuit board 3 is fixedly connected to the tray 2 by the fixing screw 13, and when the tray 2 is mounted on the box body 1, the circuit board 3 is arranged on the lower side of the tray 2.
