Cooling pipes are welded at equal intervals on the outside of the transformer body. An inlet tank and an outlet tank are fixed sequentially on one side of the transformer body.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figures 1-8 .

[0046] To address the problems in existing technologies where the structure is complex and the heat from the transformer is transferred to the heat sink, making it inconvenient to quickly circulate and cool the heat sink, thus requiring improvement in cooling efficiency, this solution proposes a fully encapsulated water-cooled transformer. The transformer body 1 is equipped with a transformer body 1 and a support bracket 4 positioned below the transformer body 1 for support. The transformer body 1 is mounted on the upper end of the support bracket 4 via a positioning component at its lower end. Cooling components are symmetrically arranged on the left and right sides of the transformer body 1.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning assembly consists of a base plate 6 and a fixing column 8 arranged in a "T" shape, a fixing block 7 to prevent rotation, and a fixing cap 9 with locking and limiting function. The lower end of the transformer body 1 is fixed with a support plate 2. The front and rear ends of the support plate 2 are provided with fixing grooves 3. The transformer body 1 is lifted by an external lifting tool and placed on the bearing bracket 4. The fixing groove 3 is aligned with the protrusions 5 fixed on the front and rear sides of the bearing bracket 4, so that the protrusions 5 are engaged in the fixing groove 3, which facilitates the positioning of the transformer body 1. After positioning, the base plate 6 drives the fixing column 8 to be inserted into the bearing bracket 4. At the same time, the fixing column 8 is inserted into the front and rear ends of the support plate 2 respectively. The base plate 6 is engaged with the fixing block 7 fixed on the inner side of the bearing bracket 4. Then, the fixing cap 9 threaded to the outer surface of the fixing column 8 is rotated so that the fixing cap 9 is fitted against the upper end of the support plate 2, which facilitates the pressing and fixing of the support plate 2 and the stable installation of the transformer body 1.

[0048] like Figure 6 , Figure 7 and Figure 8 As shown, the cooling assembly consists of a cooling box 10, cooling copper plates 11 fitted to the left and right sides of the transformer body 1, and cooling fins 12 fixed to the outside of the cooling copper plates 11 and immersed in the coolant inside the cooling box 10. A sealing gasket 13 is fitted between the cooling box 10 and the cooling copper plates 11 to prevent leakage. The cooling copper plates 11 are fixed in the cooling box 10. Mounting plates 14 are fixedly connected to both the upper and lower ends of the cooling box 10. The mounting plates 14 are fitted onto the outside of the mounting posts 15 fixed to the outer side of the transformer body 1, so that the cooling copper plates 11 are respectively fitted to the left and right ends of the transformer body 1. Then, the mounting plates 14 and the mounting posts 15 are limited by fastening bolts 16. At the same time, the connecting pipes 17 are respectively connected to the left and right sides. The individual cooling boxes 10 at each end are connected, and the connecting pipe 17, the circulating pump 18, and the refrigeration device 19 form a refrigeration circuit. The cooling boxes 10 are filled with an appropriate amount of coolant. When the transformer body 1 generates heat during operation, the heat is transferred to the cooling copper plate 11 and the cooling fins 12. The coolant in the cooling boxes 10 quickly cools the cooling fins 12 and the cooling copper plate 11. The circulating pump 18 draws out the coolant from one side of the cooling boxes 10, and after being cooled again by the refrigeration device 19, it re-enters the cooling boxes 10 on the other side. This forms a circuit, which can continuously cool the cooling copper plate 11 and the cooling fins 12, ensuring the cooling effect on the transformer body 1.
