As an embodiment of the present invention, the cooling pipe 16 is provided around the heat sink 9, thereby improving heat conduction efficiency.
The specific working principle is as follows:
when the transformer main body 1 works, oil is used as a good cooling medium to absorb heat in the transformer main body 1, wherein the oil with higher temperature moves to a high position, and the oil with lower temperature moves relatively downwards, so that a continuous cooling process of the machine is realized; the oil with higher temperature flows out from the upper gate 4 on the side surface of the transformer main body 1, flows into the upper oil delivery pipe 7, flows into the oil inlet 10 through the upper oil delivery pipe 7, flows into the middle area of the oil tank main body 8 from the oil inlet 10, continuously rises in the oil tank main body 8, moves close to the outer wall of the oil tank under the action of the centrifugal machine 12, passes through the radiating fins 9 arranged on the oil tank main body 8, and can absorb and conduct heat in the oil to the radiating fins 30 for radiating under the condition that the flowing speed of the oil is less influenced, and the oil always naturally volatilizes and radiates in the movement, so that the simple radiation of the oil can be completed; the low-temperature oil after heat dissipation moves downwards until flowing out of the oil tank main body 8 from the oil outlet 11, flows to the lower gate 5 through the lower oil delivery pipe 6, and finally flows into the transformer main body 1 to provide a cooling effect again.
However, when the temperature of the transformer main body 1 is too high, or the environmental temperature of the whole device is extremely high, the high-temperature oil is difficult to completely dissipate through the heat dissipation fins 9 and the natural heat dissipation effect, a large amount of high-temperature oil can be accumulated at the top of the oil tank main body 8, and the temperature of the high-temperature oil closer to the top of the oil tank main body 8 is higher, and at this time, the cooling structure 3 needs to be started to cool the oil tank main body 8.
When the cooling structure 3 is started, the upper water pump 15 enables cooling water to flow around the oil tank main body 8 and the cooling fins 9 through the cooling pipe 16, the low-temperature cooling water can quickly absorb a large amount of heat to be converted into high-temperature hot water, a remarkable cooling effect is provided for the oil tank main body 8, then the high-temperature water flows into the lower water pump 14 and flows into the stainless steel pipe 20 through the lower water pipe 18, the stainless steel pipe 20 is arranged in a zigzag manner in space and passes through the cooling plate 28, so that the water volatilizes a large amount of heat in movement, and at the moment, the circulating water pump 23 is started, water is pumped out of the water storage tank 21 through the water pumping pipe 22, and then the water is conveyed to the spraying device 25 through the water supply pipe 24; after the spraying device 25 receives water, the water is sprayed into the area where the cooling plates 28 are distributed, at the moment, low-temperature air flows in from the air inlets 29 and flows upwards, sprayed water drops are quickly vaporized under the action of heat, so that a large amount of heat is absorbed to cool the water in the stainless steel pipe 20, the cooled low-temperature water continuously flows upwards under the action of the lower water pump 14, and finally flows back to the upper water pump 15 through the upper water pipe 19, so that the circulation of cooling water is realized; part of the vaporized moisture is blocked by the water baffle 26, drops downwards again for reuse, and the other part carries heat to flow into the fan 27 and finally is discharged out of the device through the fan 27; the water drops which are sprayed or dropped, without vaporization line, fall into the water storage tank 21 again, so that the water can be recycled.
