the inverter body 200 is mounted on a plurality of the heat dissipation posts 510.
In the present embodiment, the plurality of heat dissipation posts 510 conduct heat generated by the inverter body 200 to the bottom of the inverter case 100, thereby re-dispersing the heat of the inverter body 200.
It should be noted that, in order to better disperse the heat at the bottom of the inverter housing 100, a supporting device is required to be disposed outside the inverter housing 100, so that the bottom of the inverter housing 100 becomes hollowed out, and thus the heat is better dissipated.
Further, the material of the heat dissipation post 510 may be copper, aluminum, graphene or other materials capable of achieving a heat dissipation effect, which is not limited herein.
In one embodiment, the drying structure 600 includes a plurality of movable bearing boxes 610, clamping blocks 620, anti-skid blocks 630 and a screen 640;
the movable carrier 610 is installed in the inverter case 100;
The clamping blocks 620 are symmetrically arranged on the movable bearing box 610;
the bottom of each clamping block 620 is provided with an anti-skid block 630;
The screen 640 is arranged on the bearing box in a covering way;
the inverter housing 100 is provided with a chute 120 adapted to the fixture block 620;
The bearing box comprises an active state and a fixed state;
When the bearing box is in an active state, the bearing box is moved upwards by an external force, at this time, the anti-skid blocks 630 are separated from the bottom wall of the sliding groove 120, and at this time, the bearing box is movably installed in the inverter housing 100;
When the bearing box is in a fixed state, the anti-skid blocks 630 are tightly attached to the bottom wall of the sliding groove 120, and the bearing box is fixed in the inverter housing 100.
In this embodiment, the bagged drying agent can be placed by the movable bearing box 610, and the movable bearing box 610 can be moved by pushing the movable bearing box 610 upwards, and after the movable bearing box 610 is put down again, the anti-skid blocks 630 contact with the bottom wall of the sliding groove 120, so that the movable bearing box 610 can be fixed on the sliding groove 120 without fixing a locking piece, thereby saving materials and being convenient to operate.
It should be noted that, the movable carrying case 610 needs to be provided with a vent hole, so that a better drying effect can be achieved, and the heat dissipation element 330 is not blocked to drive the air above the inverter body 200 to flow.
Further, a plurality of movable carrying cases 610 can be installed according to the need, and because the humidity conditions of different areas are inconsistent, how many movable carrying cases 610 are needed to be installed can be determined according to the need, and expansion is performed.
