[0034] like Figure 1-Figure 4As shown, this embodiment provides a transformer with a cooling function, which includes a box 100, a transformer 200, an air-water heat exchanger 300 and a spoiler fan 400. A heat dissipation channel 101 is formed in the box 100, the transformer 200 is arranged in the heat dissipation channel 101, the air-water heat exchanger 300 is fixed on the inner wall surface of one side of the box 100 and is located in the heat dissipation channel 101, and the industrial cooling water exchanges heat with the air in the heat dissipation channel 101 at the air-water heat exchanger 300, and the air in the heat dissipation channel 101 can be cooled by the air-water heat exchanger 300. The spoiler fan 400 is arranged on one side of the air-water heat exchanger 300 and is located in the heat dissipation channel 101. The spoiler fan 400 can blow the low-temperature air 10 after heat exchange to the transformer 200. When the low-temperature air 10 contacts the high-temperature transformer 200, the low-temperature air 10 absorbs the heat of the transformer 200 and becomes high-temperature air 20. The temperature of the transformer 200 drops, and then the high-temperature air 20 flows back to the air-water heat exchanger 300 through the heat dissipation channel 101 for cooling. This cycle is repeated, and the air circulating in the heat dissipation channel 101 continuously takes away the heat of the transformer 200, thereby avoiding heat accumulation and overheating of the transformer 200.

[0035] In addition, the heat dissipation channel 101 in this embodiment is a closed channel, and the air in the heat dissipation channel 101 and the air-water heat exchanger 300 transfer heat to the industrial cooling water through wall-connected heat exchange. Since the temperature of the industrial cooling water is relatively constant, the heat of the air in the heat dissipation channel 101 can be continuously taken away by the industrial cooling water, and then the low-temperature air 10 in the heat dissipation channel 101 can cool the transformer 200, and the transformer 200 is kept at a normal operating temperature, and the temperature of the transformer 200 is well controlled. In addition, there is no contact between the air in the heat dissipation channel 101 and the external environment, and the heat dissipation channel 101 will not be affected by external dust and sand, and the heat dissipation channel 101 is kept clean.

[0036] See also Figure 1 and Figure 3 The air-water heat exchanger 300 includes a circulating water pipe 310 and a fin assembly 320. Industrial cooling water flows in the circulating water pipe 310. The fin assembly 320 is arranged on the inner wall surface of the box body 100. The circulating water pipe 310 is penetrated by the fin assembly 320 and is in heat exchange contact with the fin assembly 320. The turbulent fan 400 is arranged on the side of the fin assembly 320 close to the transformer 200. The turbulent fan 400 can blow the cooled air to the transformer 200. The fin assembly 320 increases the heat exchange area between the circulating water pipe 310 and the air, which is conducive to quickly transferring the coldness of the industrial cooling water to the air in the heat dissipation channel 101, and has a good cooling effect on the air.

[0037] As an optional solution, in this embodiment, a water inlet 311 and a water outlet 312 are provided at the bottom of the box 100, and the water inlet 311 and the water outlet 312 are both connected to the circulating water pipe 310. The water inlet 311 delivers industrial cooling water to the circulating water pipe 310, and the industrial cooling water in the circulating water pipe 310 exchanges heat with the air in the heat dissipation channel 101 and flows out from the water outlet 312. By arranging the water inlet 311 and the water outlet 312 at the bottom of the box 100, on the one hand, it will not occupy the layout space around the box 100, and the structure is relatively regular; on the other hand, it also has a certain heat preservation function, which prevents the water inlet 311 and the water outlet 312 from receiving sunlight for a long time, causing the temperature of the industrial cooling water to rise. Optionally, the water inlet 311 and the water outlet 312 are both connected to a cooling tower, and the industrial cooling water is delivered to the circulating water pipe 310 of the air-water heat exchanger 300 through the cooling tower, and the cooling tower can keep the temperature of the industrial cooling water constant. The specific flow direction of the industrial cooling water is that it flows from the cooling water tower through the water inlet 311 into the circulating water pipe 310, flows out through the water outlet 312 after heat exchange with the air in the heat dissipation channel 101, and flows back to the cooling water tower for cooling, thereby forming a circulation loop of industrial cooling water. The industrial cooling water can circulate between the air-to-water heat exchanger 300 and the cooling water tower.

[0038] Furthermore, in this embodiment, the fin assembly 320 includes a plurality of heat dissipation fins 321, and the plurality of heat dissipation fins 321 extend along the height direction of the box body 100, and the plurality of heat dissipation fins 321 are sequentially arranged at intervals along the width direction or the length direction of the box body 100. Optionally, the intervals between the plurality of heat dissipation fins 321 are equal. The circulating water pipe 310 is arranged on the plurality of heat dissipation fins 321 in a serpentine coil, and the circulating water pipe 310 and the heat dissipation fins 321 are arranged in an interlaced manner, thereby increasing the contact area between the circulating water pipe 310 and the heat dissipation fins 321, so that the industrial cooling water and the air in the heat dissipation channel 101 can quickly exchange heat.

[0039] In this embodiment, a plurality of spoiler fans 400 are also provided, and the plurality of spoiler fans 400 are arranged at intervals on the fin assembly 320. By way of example, six spoiler fans 400 are provided in this embodiment, and three spoiler fans 400 form a row, and two rows are provided on the fin assembly 320. Of course, in other embodiments, the number of spoiler fans 400 can be flexibly arranged according to the size of the transformer 200 and the box 100, which is not limited here.

[0040] Continue to see Figure 2 and Figure 4The box body 100 in this embodiment includes a top wall 130, a bottom wall 140 and four side walls 110. The air-water heat exchanger 300 is fixed on the inner wall surface of one of the side walls 110, and the transformer 200 is located on one side of the side wall 110. Two windshields 120 are arranged between the transformer 200 and the air-water heat exchanger 300. One end of the two windshields 120 is connected to the side wall 110. The two windshields 120 are inclined in a direction away from the air-water heat exchanger 300. The transformer 200 is located on the inner side of the windshield 120. A trumpet-shaped ventilation channel is formed between the air-water heat exchanger 300 and the transformer 200. The trumpet-shaped ventilation channel is a part of the heat dissipation channel 101. The transformer 200 is located at the large end of the trumpet-shaped ventilation channel, and the air-water heat exchanger 300 is located at the small end of the trumpet-shaped ventilation channel. Through the air diversion effect of the windshield 120 on the air, the cooled air can be gathered and blown to the transformer 200, and the cooling effect of the transformer 200 is better.

[0041] Furthermore, the heat dissipation channel 101 includes a cold air outlet section, a heat exchange section and a return air section. A cold air outlet section is formed between the air-water heat exchanger 300 and the transformer 200, that is, the above-mentioned trumpet-shaped ventilation channel. A heat exchange section is formed at the transformer 200, and a return air section is formed at the top of the transformer 200 and the air-water heat exchanger 300. The specific air flow path in the heat dissipation channel 101 is: from the air-water heat exchanger 300, it blows toward the transformer 200 through the cold air outlet section, exchanges heat with the transformer 200 at the heat exchange section, flows to the top space of the transformer 200, then deflects into the return air section, and returns to the air-water heat exchanger 300 for cooling again, thereby forming an air circulation loop, and the air can circulate between the air-water heat exchanger 300 and the transformer 200 to achieve good heat dissipation of the transformer 200.
