After adopting the above scheme, when it is necessary to dissipate heat for the electrical components inside the cabinet 1, the cooling fan 3 is started, and the cooling air enters the air inlet duct 11, and then enters the upper air duct 43, the middle air duct 44 and the lower air duct 45 respectively, and is discharged from the upper air outlet 411, the middle air outlet 412 and the lower air outlet 413. The air guide component 4 can guide the cooling air in different directions, ensuring that the cooling air quickly reaches different positions inside the cabinet 1, thereby improving the heat dissipation efficiency.

[0032] Preferably, by Figure 1 and Figure 2 As shown, in the present embodiment, air inlet ducts 11 are fixed on the left and right sides of the cabinet 1, and exhaust holes 12 are processed on the top and bottom of the cabinet 1. After adopting the above scheme, the present invention adopts a double-sided air inlet and double-sided exhaust air cooling scheme, which can greatly improve the heat discharge efficiency in the cabinet 1, thereby improving the heat dissipation efficiency. The cooling air enters the cabinet 1 from both sides at the same time to form convection, and is discharged from the exhaust holes 12 at the top and bottom of the cabinet 1, while taking away the heat in the cabinet 1.
