Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figures, the inverter comprises a box body 1, and a control module and an inversion module which are arranged inside the box body 1, wherein the control module and the inversion module are both of conventional structures and are necessary electronic components of the inverter, and are not specifically explained here, and the box body 1 is closed to form a relatively independent unit structure.

The upper cover body 2 is installed on the upper portion of the box body 1, the lower cover body 3 is installed on the lower portion of the box body, a U-shaped installing support 12 is arranged on the right side of the box body 1, and the upper cover body 2 and the lower cover body 3 are fixedly connected with the box body 1 through bolts.

An upper cooling chamber 4 is formed between the upper cover body 2 and the upper surface of the box body 1, a lower cooling chamber 5 is formed between the lower cover body 3 and the lower surface of the box body 1, an intermediate cooling chamber 6 which is communicated with the upper cooling chamber 4 and the lower cooling chamber 5 is formed on the right surfaces of the upper cover body 2, the lower cover body 3 and the box body 1, and a cooling air circulation channel is formed by the upper cooling chamber 4, the intermediate cooling chamber 6 and the lower cooling chamber 5 together.

The left side wall of the upper cover body 2 is provided with an air inlet 21, the left side wall of the lower cover body 3 is provided with an air outlet 31, a heat radiation fan 5 is arranged at the position, corresponding to the air inlet 21, of the upper portion of the box body 1, when the heat radiation fan 5 is started, cooling air is formed to enter from the air inlet 21, sequentially pass through the upper cooling chamber 4, the middle cooling chamber 6 and the lower cooling chamber 5, form heat exchange with the outer surface of the box body 1, and finally are sent out from the air outlet 31.

By adopting the scheme, the cooling air formed by the cooling fan flows through the cooling air circulation channel, so that the surface of the box body is quickly and uniformly cooled, the air-cooled heat dissipation effect is good, the heat dissipation is more uniform and rapid, the dust accumulation of the internal electronic element is avoided, and the higher service life of the electronic element is ensured.

Further, the upper surface, the right surface and the lower surface of the box body 1 are provided with a plurality of first heat dissipation ribs 11 arranged along the flowing direction of cooling air, so that the contact area between the box body 1 and the cooling air is further increased, and the heat dissipation effect is further improved.
