[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 As shown, a transformer cooling device comprises a transformer body 1, a heat dissipation fin 2 is arranged on the outer side of the top of the transformer body 1, a device housing 3 is wrapped on the outside of the transformer body 1, an air inlet 4 is opened on the side of the device housing 3, an exhaust port 5 is opened through the top of the device housing 3, a water-cooled heat dissipation pipe 7 is laid on the outside of the transformer body 1, one end of the water-cooled heat dissipation pipe 7 is connected to a drain pipe 8, the other end of the water-cooled heat dissipation pipe 7 is connected to a water inlet pipe 11, the water inlet pipe 11 and the drain pipe 8 are respectively connected to a water tank 10, a water pump 9 is installed at the water inlet end of the water tank 10, the drain pipe 8 is connected to the water pump 9, and a heat sink 1001 is installed on the upper end surface of the water tank 10;

[0024] When the transformer body 1 is cooled, the water pump 9 can be started to drive the water in the water tank 10 to circulate in the water-cooled heat dissipation pipe 7 through the drain pipe 8 and the water inlet pipe 11. When the cooling water flows in the water-cooled heat dissipation pipe 7, the heat transferred from the transformer body 1 to the heat dissipation fins 2 is taken away through heat transfer, and after the cooling water adsorbed with heat flows into the water tank 10, it can be quickly cooled and dissipated through the heat sink 1001, so that it is convenient to flow again to dissipate heat for the transformer body 1.

[0025] like Figure 5 As shown, the heat dissipation fins 2 are evenly arranged on the transformer body 1, and a water-cooled heat dissipation pipe 7 is laid in the gap between every two heat dissipation fins 2;

[0026] A plurality of heat dissipation fins 2 are arranged on the transformer body 1, which can increase the contact area between the transformer body 1 and the air, thereby facilitating better heat dissipation, and the water-cooling heat dissipation pipe 7 is laid between the heat dissipation fins 2, which can increase the contact area between the water-cooling heat dissipation pipe 7 and the transformer body 1, thereby better transferring the heat in the transformer body 1 to the cooling water in the water-cooling heat dissipation pipe 7, thereby improving the water cooling capacity.

[0027] An air intake fan 401 is installed inside the air inlet 4, and dust covers 6 are provided at the outer ends of the air inlet 4 and the air outlet 5. A rainproof canopy 601 is installed at the top of the air outlet 5, and the upper and lower ends of the rainproof canopy 601 are conical structures;

[0028] When the transformer body 1 is dissipating heat, the water tank 10 is used for water cooling, and the air intake fan 401 can also be started to suck the cold air from the outside into the equipment housing 3 through the air inlet 4 and blow it toward the transformer body 1, so that the hot air of the transformer body 1 is discharged upward through the exhaust port 5 to achieve the purpose of air cooling, and a dust cover 6 is installed on both the exhaust port 5 and the air inlet 4, which can effectively prevent dust from entering the equipment housing 3 and play a dust-proof role for the transformer body 1, and a rainproof canopy 601 is set at the top of the exhaust port 5 to prevent rainwater from falling from the exhaust port 5 and avoid damaging the transformer body 1, and the conical structure at the upper end of the rainproof canopy 601 can play a role in preventing and discharging rain, and the conical structure at the lower end of the rainproof canopy 601 can play a role in guiding, so that the hot air emitted from the exhaust port 5 flows around along the conical surface, preventing the rainproof canopy 601 from affecting the heat dissipation of the exhaust port 5.

[0029] The structure of the water tank 10 is an anisotropic structure. The volume of the water tank 10 is small at the end connected to the drain pipe 8, and the volume of the water tank 10 is large at the side connected to the water inlet pipe 11. The heat sink 1001 is arranged in an array on the water tank 10. A heat sink fan 12 is installed on one side of the water tank 10, and the wind direction blown by the heat sink 12 is parallel to the heat sink 1001;

[0030] While water cooling is performed through the water tank 10, the cooling fan 12 can be turned on to blow air to the heat sink 1001, so that the air around the heat sink 1001 can flow faster, which is convenient for heat dissipation. In addition, the water tank 10 is small in size at the end connected to the drain pipe 8, so that the water flowing into the water tank 10 through the water-cooled heat pipe 7 through the drain pipe 8 can have a larger contact area with the water tank 10, so that the heat in the cooling water can be quickly cooled through the water tank 10 and the heat sink 1001. The water tank 10 is large in size at the side connected to the water inlet pipe 11, which can be convenient for water storage. The cooling water can be stored after cooling for easy use.

[0031] Working principle: when the transformer main body 1 is working, a large amount of heat will be generated, which needs to be dissipated in time. When dissipating heat, the water pump 9 can be started to drive the water in the water tank 10 to circulate in the water-cooled heat dissipation pipe 7 through the drain pipe 8 and the water inlet pipe 11. When the cooling water flows in the water-cooled heat dissipation pipe 7, the heat transferred from the transformer main body 1 to the heat dissipation fins 2 is taken away through heat transfer, and the cooling water adsorbed with heat can be quickly cooled through the heat sink 1001 after flowing into the water tank 10, so that it is convenient to flow again to dissipate heat for the transformer main body 1.
