The first system board card is installed in the main box body 100.

[0025] The screen mounting structure 200 is rotatably connected to the main box body 100. When the computer with the light-weight dual-system reinforced case is used, the user rotates the screen mounting structure 200, so that the light-weight dual-system reinforced case is switched from the state shown in Figure 1 and Figure 2 to the state shown in Figure 3 .

[0026] The board card fixing structure 300 is used for fixing the second system board card and the plurality of function board cards. The second system board card and the plurality of function board cards can be simultaneously fixed and installed in the same board card fixing structure 300, so that higher integration is achieved. The board card fixing structure 300 is located in the main box body 100 and close to the heat dissipation air duct, the heat generated by the second system board card and the plurality of function board cards is transferred to the board card fixing structure 300, the board card fixing structure 300 is close to the heat dissipation air duct, and the heat on the board card fixing structure 300 can be dissipated to the outside of the main box body 100 through the heat dissipation air duct. The board card fixing structure 300 is partially connected to the inner wall of the main box body 100, so that the board card fixing structure 300 bears the weight of the second system board card and the plurality of function board cards, and the second system board card and the plurality of function board cards can also be cooled outwardly through the side wall of the main box body 100.

[0027] The guide rail structure 400 is connected to the board card fixing structure 300, and forms two sliding channels 410 for sliding the second system board card and the plurality of function board cards. When the board cards are installed, two board cards are inserted into the two sliding channels 410 and slid to the fixed positions, and then the second system board card and the plurality of function board cards are fixed to the board card fixing structure 300.

[0028] The main box body 100, the screen mounting structure 200, the board card fixing structure 300 and the guide rail structure 400 are all made of magnesium-lithium alloy.

[0031] The second cold plate 320 is arranged parallel to the first cold plate 310 and close to the heat dissipation air duct. After the heat generated by the second system board card and the plurality of function board cards during operation is transferred to the second cold plate 320, the second cold plate 320 exchanges heat with the air in the heat dissipation air duct, and the heat of the second cold plate 320 is taken away by the air in the heat dissipation air duct and discharged out of the main box body 100 through the first heat dissipation hole 132 and / or the second heat dissipation hole 141.

[0032] The back plate 330 is connected to the side of the first cold plate 310 and / or the side of the second cold plate 320 and is orthogonal to the first cold plate 310 and the second cold plate 320, and is used for fixing the second system board card and the plurality of function board cards.

[0035] The bottom of the board fixing structure 300 is fixedly connected to the lower shell 120, and the board fixing structure 300 is partially connected to the inner side of the front side plate 150. The first heat dissipation hole 132 and the second heat dissipation hole 141 are located between the rear side plate 160 and the board fixing structure 300.

[0036] Further, referring to Figure 5 , the main box body 100 further comprises a fan 170 connected to the inner wall of the left side plate 130 and corresponding to the first heat dissipation hole 132. The fan 170 can accelerate the air flow rate of the heat dissipation air duct, so that the heat on the board fixing structure 300 can be quickly taken away, improving the cooling efficiency of the board.

[0037] The computer with the lightweight dual-system reinforced case has a first system board card and a second system board card configured with different operating systems, both of which are connected with a screen, a keyboard and a mouse, and work simultaneously. The switching switch is connected to the first system board card and the second system board card, and can switch between the first system board card and the second system board card, so that the screen displays the output information of one of the system board cards, and the keyboard and mouse can operate one of the board cards.
