Embodiment 1
[0024] Such as figure 1 The ventilation mechanism of the power distribution cabinet shown includes a power distribution cabinet 1, the side of the power distribution cabinet 1 is provided with a vent, and the vent includes a plurality of ventilation holes, and the dust cover is provided on the ventilation hole 2. The limit bar 3 is also fixed on the side of the power distribution cabinet 1, the cross section of the limit bar 3 is "L" shaped, one side of the limit bar 3 is fixed on the power distribution cabinet 1, and the other One side is perpendicular to the side of the distribution cabinet 1.
[0025] The opening formed by the dustproof cover 2 and the distribution cabinet 1 is downward.
[0026] The dust-proof cover 2 includes two dust-proof sheets vertically fixed to each other, and one dust-proof sheet is vertically fixed on the side of the power distribution cabinet 1 .
[0027] Described air vent has two rows.
[0028] There are two limiting strips 3.
[0029] The ...
Embodiment 2
[0031] This embodiment is substantially the same as the embodiment 1. In order to facilitate heat dissipation, the following improvements are made on the basis of the embodiment: the dust cover 2 is arranged in an arc shape. According to the principle of air circulation, the dust-proof cover is set in an arc shape, which is more conducive to the flow of heat. Compared with the solution in Example 1, the flow of heat is faster.
