[0043] Example 2

[0044] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 8 The difference between the technical solution of the embodiment 1 and the embodiment 2 is that, in the embodiment 2, three bases 1 are provided, and the three bases 1 are arranged side by side. Two vertical panels are connected to each base 1, and each vertical panel is composed of three vertical panel blocks 6 spliced ​​together. Each vertical panel block 6 is provided with a second connecting groove 16 on both panel surfaces.

[0045] According to actual conditions, the number of the base 1, the top cover 2, the vertical plate and the back plate 3 can be increased or decreased accordingly, so as to increase or decrease the number of the formed accommodating chambers accordingly to meet the needs of classified installation of electrical components; since the accommodating chambers formed inside the cabinet are independent of each other, and each accommodating chamber is provided with a first air vent 18 and a first exhaust fan 19 on the base 1 corresponding to the accommodating chamber, and a second air vent 20 and a second exhaust fan 21 on the top cover 2, an independent gas flow path can be formed in each accommodating chamber, effectively avoiding the internal gas of the cabinet from circulating between the various accommodating chambers and causing mutual interference, and avoiding heat conduction between the various accommodating chambers, thereby improving the heat dissipation efficiency; by adjusting the air volume of the first exhaust fan 19 and the second exhaust fan 21 corresponding to each accommodating chamber, the gas flow speed in each accommodating chamber can be changed individually, which can not only discharge heat in time and ensure the normal operation of the electrical components, but also reduce energy consumption. For the accommodating chambers installed with electrical components with low heat generation, the air volume of the two exhaust fans can be reduced, and for the accommodating chambers installed with electrical components with high heat generation, the air volume of the two exhaust fans can be increased.
