[0020] Example: Figure 1-3 As shown, the utility model provides a transformer with strong heat dissipation, including a transformer body 1, a heat dissipation fin 11 is fixedly arranged on the side wall of the transformer body 1, a bottom plate 12 is fixedly arranged on one side of the bottom of the transformer body 1, a cooling box 13 is installed on the upper surface of the bottom plate 12, the interior of the cooling box 13 is divided into a cooling groove 16 and a heat dissipation groove 15 by a partition 14, the cooling groove 16 is located above the heat dissipation groove 15, the cooling groove 16 is filled with cooling water, and two symmetrically distributed first delivery pipes 17 are installed on the upper surface of the outer wall of the cooling box 13, and the first delivery pipes 17 are installed on the upper surface of the outer wall of the cooling box 13. A first cooling water pipe 18 is connected to the top of the tube 17. One end of the first cooling water pipe 18 away from the first delivery pipe 17 passes through the heat sink 11. A second delivery pipe 19 is fixedly provided at the bottom of the heat sink 11. One end of the bottom of the second delivery pipe 19 away from the first cooling water pipe 18 is connected to the heat sink 15 inside the cooling box 13. A second cooling water pipe 2 is installed together at one end of the two second delivery pipes 19 located in the heat sink 15. One end of the second cooling water pipe 2 away from the second delivery pipe 19 passes through and is inserted into the cooling sink 16.

[0021] One end of the first delivery pipe 17 close to the cooling box 13 is connected via a first water pump 171 .

[0022] By adopting the above technical solution, the first water pump 171 can transport the cooling water filled in the cooling tank 16 to the first cooling water pipe 18 through the first delivery pipe 17 .

[0023] The second cooling water pipe 2 and the first cooling water pipe 18 are both arranged in an S shape.

[0024] By adopting the above technical solution, the S-shaped setting can make the cooling water flow paths more frequent and the contact area larger, so as to achieve better heat dissipation.

[0025] An inclined fan 21 is installed at the upper end of the inner wall of the heat dissipation groove 15 close to the transformer body 1 , and the output end of the fan 21 faces the second cooling water pipe 2 . An exhaust port 22 is opened at the bottom of the cooling box 13 away from the transformer body 1 .

[0026] By adopting the above technical solution, when the fan 21 is started, the cooling water in the second cooling water pipe 2 can be cooled, so that the temperature of the heat-absorbing cooling water is reduced, which is convenient for the subsequent circulation to better cool the heat on the cooling fins 11. At the same time, the exhaust port 22 can discharge the gas in the heat dissipation slot 15 to replace the cold air.

[0027] A vertically arranged dustproof net 23 is fixedly provided at the exhaust port 22 .

[0028] By adopting the above technical solution, the dustproof net 23 is provided to prevent dust from entering the cooling box 13 through the exhaust port 22 and thus preventing dust and other impurities from entering the cooling box 13 through the exhaust port 22 and causing damage to the interior of the cooling box 13 .

[0029] A water tank 3 is installed on the side of the cooling box 13 away from the transformer body 1, and cooling water is stored in the water tank 3. A third delivery pipe 32 is connected to the side wall of the water tank 3 through a second water pump 31. The third delivery pipe 32 is connected to the cooling tank 16 at one end away from the second water pump 31. A water level detection probe 37 is installed on the upper end of the cooling box 13, and the water level detection probe 37 is electrically connected to the second water pump 31.

[0030] By adopting the above technical solution, when the overall water volume of cooling water decreases after working for a long time, the water in the cooling tank 16 is monitored by the water level detection probe 37. When the set water flow is less than the threshold value encountered, the second water pump 31 will work and input water into the cooling tank 16 through the third delivery pipe 32 to replenish water, thereby ensuring that the cooling water can be fully input into the first cooling water pipe 18 to dissipate heat for the heat dissipation fins 11, thereby ensuring the stable operation of the device.

[0031] A water inlet bucket 33 is installed at one end of the water tank 3 away from the cooling tank 13 , and a mounting frame 34 is installed at one end of the water inlet of the water inlet bucket 33 , and a fine screen filter 35 is installed in the mounting frame 34 .

[0032] By adopting the above technical solution, the water inlet bucket 33 and the fine screen filter 35 are set up so that rainwater can be collected when it rains, thereby improving the utilization of water resources. The fine screen filter 35 can filter and intercept impurities in the rainwater.

[0033] Hooks 36 in an inverted U shape are fixedly provided at both ends of the installation frame 34 , and the hooks 36 can be clamped in the water inlet bucket 33 .

[0034] By adopting the above technical solution, the hook 36 is provided to quickly install the installation frame 34 and facilitate subsequent disassembly.

[0035] Working principle: In actual use, the first water pump 171 can transport the cooling water filled in the cooling tank 16 to the first cooling water pipe 18 through the first delivery pipe 17. At this time, the cooling water will flow from the first cooling water pipe 18, so as to take away the heat on the heat sink 11, so that the temperature of the heat sink 11 itself can be cooled down, so that the heat sink 11 after cooling can more efficiently absorb heat from the transformer body 1 to cool it down. When the cooling water flows through the first cooling water pipe 18 to the second delivery pipe 19 at the bottom, it will enter the second cooling water pipe 2. At this time, the heated cooling water will flow in the second cooling water pipe 2. When the fan 21 is started, it can dissipate the heat of the cooling water in the second cooling water pipe 2, so that the temperature of the heat-absorbing cooling water is reduced, which is convenient for the subsequent circulation to better cool down the heat on the heat sink 11. The cooled cooling water will enter the cooling tank 16 and wait for the next cooling cycle.

[0036] When the overall water volume of cooling water decreases after working for a long time, the water in the cooling tank 16 is monitored by the water level detection probe 37. When the set water flow is less than the threshold value encountered, the second water pump 31 will work and input water into the cooling tank 16 through the third delivery pipe 32 to replenish water, thereby ensuring that the cooling water can be fully input into the first cooling water pipe 18 to perform heat dissipation operations on the heat sink 11.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
