step two: then the corrugated pipe (11) is placed in the pit, the assembly and disassembly strip (20) is used for supporting the pit opening, then the low-voltage electrical cabinet (1) is placed on the assembly and disassembly strip (20), the upper end of the corrugated pipe (11) is inserted into an underground cold air inlet area, and finally the installation process is realized by screwing on a screw;
step three: when the temperature is not too high, only the fan (8) is started to guide underground cold air into the cabinet body, and the generated heat gas is discharged from the air holes or the ventilation grooves of the cabinet body, so that the internal and external pressures are balanced; when the external environment temperature or the temperature of the electric appliance elements in the cabinet is too high, the first air pump (16) and the water pump (19) are started, and the circulating heat dissipation type cooling effect in the cabinet is achieved.
