Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1, the valve mechanism for controlling the environmental ventilation of electronic equipment according to the present embodiment includes a cabinet 1 for electronic equipment and a bracket 2 for supporting the cabinet 1.

Referring to fig. 2, the casing includes a left side panel 11, a right side panel, a left side frame 14, a right side frame, a casing rear frame 12, and a casing rear panel 13.

Fins are arranged on the left side panel 11 and the right side panel, and the left side panel 11 and the left side frame 14 are separated by a certain distance and then are brazed to form a left air cavity 31; similarly, the right panel of the case and the right frame of the case are brazed to form a right air cavity 32, and each hardware module in the electronic equipment is fixedly installed in the slots of the left frame 14 and the right frame of the case through the locking strips; the heat is transferred to the fins of the left side panel 11 and the right side panel through the heat conducting plate, and the heat is taken away during ventilation.

The rear chassis frame 12 of the chassis is separated from the rear panel 13 of the chassis by a certain distance and then brazed to form a rear air cavity 33; the left air cavity 31, the right air cavity 32 and the rear air cavity 33 are communicated. The rear frame 12 of the chassis is provided with a boss, and the rear panel 13 of the chassis is provided with a through hole aligned with the boss.

Referring to fig. 2, the bracket includes a bracket rear frame 22, a rear frame cover 24, and a valve, and the bracket rear frame 22 is brazed to the rear frame cover 24 at a distance to form a wind chamber 34. The rear frame cover 24 is also provided with an air inlet 27 which communicates with an air chamber 34.

As shown in fig. 2, taking one of the valves as an example, when the chassis is pushed into the bracket, the boss on the bracket rear frame 12 pushes the valve core 23 on the bracket open, the rear air chamber 33 is communicated with the air chamber 34, when the air inlet 27 is ventilated, the ring-controlled air flows into the rear air chamber 33 through the air chamber 34, then flows into the left air chamber 31 and the right air chamber 32 through the slots on the bracket rear frame 12, the left side frame 14 and the right side frame, and is exhausted through the air exhaust slots on the left side panel 11 and the right side panel, and takes away the heat of the fins on the left side panel 11 and the right side panel, so as to achieve the purpose of dissipating heat of the module.
