4. The variable frequency cabinet with good heat dissipation effect according to claim 3, wherein: the two protection plates (26) are symmetrically arranged about the central axis of the cabinet body (1).
5. The method for using the frequency conversion cabinet with good heat dissipation effect according to any one of claims 1 to 4, comprising the following steps:
s1: when the temperature inside the variable frequency cabinet is higher, the temperature of the electric element (33) in the rectangular frame (7) can be absorbed through cold water in the cooling bin (6);
s2: then starting a water suction pump (9) and a refrigerator (13), wherein the water suction pump (9) sucks hot water in the water storage bin (3) through a water suction pipe (10), so that the hot water in the cooling bin (6) is led into the water storage bin (3) through a water discharge pipe (8) and sucked out through the water suction pipe (10), and when the water suction pipe (10) sucks out the hot water in the water storage bin (3), cold air is generated through the refrigerator (13), and then the hot water in the water suction pipe (10) can be cooled, so that the cold water is led into the cooling bin (6) again through a water guide pipe (11);
s3: then starting a blowing fan (18), then guiding wind power into the rectangular frame (7) through the first air inlet hole (17) by the blowing fan (18), and then cooling the electric elements (33) in the rectangular frame (7);
s4: then an exhaust fan (32) is started, and then heat is led out of the cabinet body (1) through the second ventilation holes (20) by the exhaust fan (32) and the second ventilation holes (19), so that the frequency conversion cabinet is cooled by air;
s5: finally, when the variable frequency cabinet is impacted by external force, the protection plate (26) pushes the cross rod (25) and the movable block (23) to move towards the direction of the cabinet body (1), then the first spring (24) is compressed, so that the impact force borne by the cabinet body (1) is reduced through the elastic reset action of the first spring (24), meanwhile, the protection plate (26) pushes the fixed block (29) to move towards the direction of the cabinet body (1), then the fixed block (29) pushes the two rotating blocks (30) to rotate, then the two rotating blocks (30) push the two moving blocks (27) to be away from each other, the second spring (31) is stretched, and the impact force borne by the cabinet body (1) is reduced through the elastic reset action of the second spring (31), so that electric elements (33) in the rectangular frame (7) are protected.
