the method comprises the following steps: the switch lock on the switch cabinet door (4) is opened or closed by a key to open or close the switch cabinet door, an electric component is placed in the inner cabinet body (29), the electric component emits a large amount of heat energy when working, the first driving motor (20) works to drive the bevel gears (21) to rotate, the bevel gears (21) drive the upper and lower groups of third bevel gears (18) and the third connecting shaft (17) to rotate, the third bevel gears (18) on the third connecting shaft (17) drive the second bevel gears (16) and the second connecting shaft (15) to rotate, the first bevel gears (13) on the upper and lower ends and the first connecting shaft (11) are driven by the two groups of second bevel gears (16) to rotate, the first connecting shaft (11) drives the sealing rotating seat (10) to rotate to open or close a gap on the sealing fixed seat (9), and therefore the opening and closing of the top heat dissipation port (2) and the bottom heat dissipation port (5) are realized, when the switch cabinet works, the heat dissipation port is opened to dissipate heat of the inner cabinet body (29), when the external environment is humid, the heat dissipation port is closed to prevent the humid environment from influencing electrical components inside the switch cabinet, when the heat dissipation port is opened, the two groups of heat dissipation fans (24) work simultaneously to blow and dissipate heat of the inner cabinet body (29), and the two groups of heat dissipation fans (24) are same in blowing direction to accelerate air circulation inside the outer cabinet body (1) of the switch cabinet, so that quick heat dissipation inside the outer cabinet body (1) of the switch cabinet is realized;
step two: when the electric components in the inner cabinet body (29) work, the circulating water pump (26) works to pump out the circulating water tank (25), the circulating water flows into the cooling water pipe (27) attached to the second partition plate (23), the heat energy dissipated in the inner cabinet body (29) is taken away through the heat conduction of the cooling water, the cooling water pipe (27) is continuously paved on the second partition plate (23) in an S shape to improve the water-cooling heat dissipation effect, the cooling water flows into the condenser (28) through the cooling water pipe (27) to be cooled and cooled, and then flows back into the circulating water tank (25) to be recycled, and a plurality of side heat dissipation ports (3) are arranged on the side wall provided with the circulating water tank (25) and the condenser (28) to dissipate heat of the circulating water tank (25) and the condenser (28).
