7. The frequency conversion cabinet with good heat dissipation effect as claimed in claim 5, wherein: the two protection plates (26) are symmetrically arranged around the central axis of the cabinet body (1).
8. The use method of the frequency conversion cabinet with the good heat dissipation effect according to any one of claims 1 to 7, characterized by comprising the following steps:
s1: when the temperature inside the frequency conversion cabinet is higher in use, the temperature of the electric elements (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), sucking water in the water storage bin (3) by the water suction pump (9) through a water suction pipe (10), leading hot water in the cooling bin (6) into the water storage bin (3) through a water discharge pipe (8), sucking the hot water through the water suction pipe (10), generating cold air through the refrigerator (13) when the hot water in the water storage bin (3) is sucked out by the water suction pipe (10), and then cooling the hot water in the water suction pipe (10), so that the water is led into the cooling bin (6) again through a water guide pipe (11);
s3: then starting a blast fan (18), guiding wind power into the rectangular frame (7) through the first air inlet hole (17) by the blast fan (18), and cooling the electric element (33) in the rectangular frame (7);
s4: then, the exhaust fan (32) is started, and then heat is led out of the cabinet body (1) through the second vent hole (20) through the exhaust fan (32) and the second air inlet hole (19), so that the air cooling and the temperature reduction of the frequency conversion cabinet are completed;
s5: finally when this frequency conversion cabinet receives external force and assaults, guard plate (26) promote horizontal pole (25) and movable block (23) and remove towards the direction of the cabinet body (1), then compress first spring (24), thereby elasticity reset action through first spring (24), reduce the impact force that the cabinet body (1) received, meanwhile, guard plate (26) promote fixed block (29) and remove towards the direction of the cabinet body (1), then promote two turning blocks (30) through fixed block (29) and rotate, and then promote two movable blocks (27) through two turning blocks (30) and keep away from each other, and tensile second spring (31), thereby elasticity reset action through second spring (31), reduce the impact force that the cabinet body (1) received, thereby protect electric elements (33) in rectangular frame (7).
