the method comprises the following steps: the first air cooler (71) and the second air cooler (72) work to quickly replace air in the shell (1) and simultaneously dissipate heat through heat exchange of the circulating pipeline (73);
step two: the induced draft fan (74) introduces new air filtered by the filter (75), and when the air pressure in the equipment is increased, the diaphragm valve (77) is opened to send out old air;
step three: the temperature sensor (78) detects the temperature in the shell (1), when the temperature is too high, the oil mist generator (79) is started to spray cooling oil to assist in cooling, and meanwhile, the mist blocking net (710) and the oil dropping groove (711) prevent oil mist from entering the circulating pipeline (73).
