In the above embodiment, as shown in fig. 3, the first heat dissipation hole 16 and the second heat dissipation hole 18 are located on the same side of the frame 1. This arrangement is achieved by providing the first louver 16 and the second louver 18 on the same side of the frame 1. The arrangement of a heat sink 5 in this way enables heat to be dissipated from the strong current chamber 7 and the weak current chamber 6. And a plurality of heat dissipation devices 5 are not needed, so that the cost is reduced, and the space of the electric cabinet is increased. In addition, set up the louvre with same one side and make the louvre on the frame 1 can concentrate the distribution on same curb plate, avoid all setting up the louvre on a plurality of curb plates. Meanwhile, the arrangement also facilitates the hot air exhausted by the electric cabinet to be further intensively exhausted to the outside. Namely, the arrangement is more beneficial to further exporting the subsequent heat.

Further, when the heat sink 5 is disposed in both the strong current cavity 7 and the weak current cavity 6, the heat sink 5 of the strong current cavity 7 and the heat sink 5 of the weak current cavity 6 are located on the same side of the frame 1.
