[0030] Example 1: See Figure 1-9 A heat dissipation cabinet door is installed on a server rack. The heat dissipation cabinet door includes a door body 01 and a heat dissipation component 02. A square exhaust area 11 is provided on the upper part of the heat dissipation cabinet door, and exhaust holes 111 are densely distributed in this area. The heat dissipation component 02 is installed on the inner side of the exhaust area 11. The heat dissipation component 02 blows hot air from inside the server rack out through the exhaust area 11, thereby reducing the temperature inside the server rack.

[0031] The heat dissipation assembly 02 includes a plurality of cooling fans 21 and a fan mounting bracket 22. The cooling fans 21 are mounted on the fan mounting bracket 22. The fan mounting bracket 22 has evenly distributed circular air holes 221 corresponding to the cooling fans 21.

[0032] The size and outline of the fan mounting bracket 22 correspond to the size of the exhaust area 11. This allows all the cooling fans 21 to be connected as a whole, improving the modularity of the heat dissipation assembly 02.

[0033] There are 9 circular air vents 221, and there are also 9 cooling fans 21.

[0034] A weight-reducing perforation 222 is provided between adjacent circular air holes 221. This allows for weight reduction of the fan mounting bracket 22, thus lowering the overall weight.

[0035] A louvered air deflector 03 is also provided between the heat dissipation component 02 and the exhaust area 11 of the heat dissipation cabinet door. The size and outline of the louvered air deflector 03 correspond to the size of the exhaust area 11. This can prevent external sand and gravel from affecting the cooling fan 21.

[0036] The louvered air deflector 03 includes a frame 31 and several parallelly arranged guide blades 32, which are fixed downwards within the frame 31. This design guides the blown hot air, preventing it from blowing directly to the outside.

[0037] The cabinet door is also equipped with a locking device 04.

[0038] The locking device 04 includes a rotating handle 41, a transmission assembly 42, guide rods 43, guide blocks 44, and a fixed base 45. The rotating handle 41 is rotatably connected to the transmission assembly 42, with the rotating handle 41 installed on the outside of the cabinet door and the transmission assembly 42 installed on the inside of the cabinet door. Two guide rods 43 are provided, each connected to the transmission assembly 42. Several guide blocks 44 and fixed bases 45 are provided. The fixed bases 45 are located on the inside of the cabinet door, and the guide blocks 44 are correspondingly installed on the fixed bases 45. The guide blocks 44 and guide rods 43 are slidably engaged. A roller 431 is provided at the end of the guide rod 43 away from the transmission assembly 42. The transmission device converts the rotation of the rotating handle 41 into linear motion of the guide rod 43. After the guide rod 43 extends along the direction of the guide block 44, it can cooperate and fix with the cabinet body, thereby locking the cabinet door.

[0039] The transmission device in this embodiment can adopt the structure disclosed in the prior art (Chinese Patent: CN219106807U - A power distribution cabinet with a top and bottom locking mechanism).

[0040] The working principle of this embodiment:

[0041] Hot air inside the cabinet is drawn out by the cooling fan 21 and blown out through the louvered air deflector 03 and the ventilation holes. At the same time, ventilation holes in other parts of the cabinet replenish the cabinet with cool air from the outside, achieving thermal circulation of air inside the cabinet and maintaining the temperature inside the cabinet at a low level.

[0042] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that both the front and back of the cabinet are equipped with heat dissipation cabinet doors; the heat dissipation components 02 on the front cabinet door are installed facing forward, while the heat dissipation components 02 on the back cabinet door are installed in reverse. The reverse installation of the heat dissipation components 02 on the back of the cabinet allows external air to be drawn into the cabinet, and the opposite installation of the cooling fans 21 on both sides improves the efficiency of air circulation inside the cabinet.

[0043] Dustproof cotton is installed between the louvered air deflector 03 on the rear heat dissipation cabinet door and the exhaust area 11 of the cabinet door body 01. This prevents external dust from entering the cabinet and affecting the equipment inside.
