Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-3 , a reinforced rack-mountable air-cooled chassis, comprising:
[0027] The lower box body 10 has an air outlet 17 at the rear end thereof, a fan 24 is installed at the rear end thereof, and both sides of the lower box body 10 have rail mounting threaded holes 9 for mounting the guide rails;
[0028] Specifically, such as Figure 1 and Figure 2 As shown, during installation in the prior art, guide rails are installed on both sides of the lower box body 10 to facilitate installation and coordination with the cabinet body.
[0029] The power supply component, the power conversion module 22 is arranged inside the lower box 10, and the output end of the power conversion module 22 is installed with a power filter module 21;
[0030] The board assembly includes a board body 25 , which is mounted on the inner wall of the lower housing 10 , and a board heat sink 23 is provided on the upper layer of the board body 25 ;
[0031] The board heat sink 23 is a multi-tooth structure, and a contact surface is provided between the board heat sink 23 and the board body 25, and a silicone gasket is filled between the contact surface and the board body 25;
[0032] Specifically, such as Figure 1 and Figure 3 As shown, part of the heat generated by the board body 25 is conducted to the lower box body 10 through the fixing studs, and most of the heat is conducted to the surface of the board heat sink 23 through the contact with the device. The board heat sink 23 is a multi-tooth structure. This design can increase the effective heat dissipation area. A dustproof net to improve the protection level and an electromagnetic shielding net to improve electromagnetic compatibility are provided at the air inlet of the front panel 3.

When dissipating heat, cold air enters through the heat dissipation holes of the front panel 3, passes through the board heat sink 23 for heat exchange, and the hot air carrying heat is blown out through the heat dissipation holes on the lower box body 10. This process is a front-in airflow and back-out airflow form.

The front and rear handles are connected to the various components of the chassis with high-strength carbon steel fasteners. This design is not only convenient for installation and transportation, but also can provide support and protection for the front and rear panels of the chassis.
[0037] The upper cover plate 13 is disposed above the lower box body 10 , and a plurality of countersunk holes 12 are vertically penetrated inside the upper cover plate 13 .
[0038] The power supply aviation plug 19 is electrically connected to the power conversion module 21 through a cable, the power conversion module 21 is electrically connected to the power filter module 22 through a cable, and the power filter module 22 is plugged into the board body 25 through a cable and a connector;

[0041] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the input end of the power conversion module 22 is connected to the power supply aviation plug 19 on the rear panel of the lower box 10, and the output end is connected to the power filter module 21 to power the board body 25. The fan 24 module is powered and controlled by the board body 25 through a cable. The front end connector of the board body 25 directly extends out of the front panel 3, and the external adapter connector on the rear panel is connected to the board body 25 through a cable (not shown in the figure).
