when the temperature of the cooling oil in the protective housing 1 is too high, the gas in the square block 101 expands due to the temperature rise, so that the communication rod 103 moves downwards, the tension spring 102 is stretched, the contact block 105 and the contact groove 106 are contacted when the tension spring 102 moves downwards, the oil pump 11, the second motor 807 and the first motor 3 start to operate, the cooling oil in the protective housing 1 enters the L-shaped pipe 104, the bending pipe 14 and the oil inlet pipe 13 when the oil pump 11 operates, and the bending pipe 14 bends, so that the contact area of the cooling oil and the bending pipe 14 is increased, the first natural cooling of the cooling oil is realized, the cooling oil is conveyed to the inner cavity of the oil outlet pipe 12 through the oil pump 11, and finally the cooling oil is sprayed out from one side of the oil outlet pipe 12 close to the separation bin 801;
through the operation of the second motor 807, the third bevel gear 808 rotates, and the first bevel gear 805 and the second bevel gear 806 rotate in opposite directions, so that the inner rod 804 and the outer ring sleeve 803 respectively drive the first blade 802 and the second blade 812 to rotate at high speed in opposite directions, the cooling oil sprayed from the oil outlet pipe 12 is scattered by the device, the cooling oil is atomized, the atomized cooling oil is separated into lower-temperature oil mist and higher-temperature oil mist, the lower-temperature oil mist enters the inner cavity of the condensation bin 811 through the separation bin 801 and is condensed, and the lower-temperature oil mist enters the inner cavity of the protective housing 1 through the bottom of the condensation bin 811, so that the cooling of the lower-temperature cooling oil mist is completed;
meanwhile, the fan blades 4 are rotated by the operation of the first motor 3, so that cooling air flows generated by the fan blades 4 are conveyed to the bottom of the cooling air inlet 504 through the top of the air cooling bin 6 and then conveyed to the inner cavity of the exhaust pipe opening 503 in the inner part of the annular pipeline 501, meanwhile, oil mist with higher temperature enters the inner cavity of the annular pipeline 501 through the U-shaped pipe 809 and the oil mist air inlet 502, at the moment, the cooling air flows conveyed into the inner cavity of the exhaust pipe opening 503 cool the cooling oil mist with higher temperature which is introduced into the inner part of the annular pipeline 501, at the moment, the cooling oil mist with higher temperature in the inner part of the annular pipeline 501 is condensed into liquid, then the liquid cooling oil is discharged from the oil outlet 505 and flows into the inner cavity of the first connecting pipe 7, and finally the cooled cooling oil returns to the inner cavity of the protective housing 1 again through the bottom of the first connecting pipe 7, so that cooling of the cooling oil is completed, and normal operation of the distributor body 15 is ensured.
