[0002] The transformer radiator structure is used to solve the heat generation problem of piezoelectric transformers during operation, suppress the temperature rise of the piezoelectric transformer during operation, and thus achieve reliable operation and high power density energy transmission. A search revealed an existing technology (Announcement No.: CN202320720691.7) describing a transformer radiator structure. The description states that "the radiator includes radiator oil pipes, radiator fins, and oil pipe connection structures. Multiple radiator fins are provided at the top and bottom of each fin, and the fins are connected to the radiator oil pipes. The transformer oil tank is connected to the radiator oil pipes through the oil tank outlet pipe. The two sides of the radiator oil pipes are connected to the radiator fins and oil pipe connection structures respectively. This increases the heat dissipation area and the bottom circulation pressure, thereby improving the cooling speed of the transformer oil, enhancing the transformer's heat dissipation capacity, protecting the transformer, and further contributing to the normal operation of the transformer." However, the existing technology suffers from the problem of uneven heat dissipation caused by impurities blocking the gaps between the radiator fins on the transformer side, which obstructs the heat dissipation of certain oil pipes. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, a transformer radiator structure is provided to solve the problem that blockages in the gaps between the heat sink fins on the side of the transformer cause obstruction of heat dissipation in the oil pipe, thus affecting the heat dissipation performance.
[0004] To achieve the above objectives, a transformer radiator structure is provided, including an oil tank output pipe and an oil tank input pipe, with the oil tank output pipe and oil tank input pipe connected to both the front and rear sides of the transformer body.
[0005] The transformer body has oil coolers symmetrically fixed on its front and rear ends. The upper end of the oil cooler is connected to the oil tank output pipe through the oil inlet, and the lower end of the oil cooler is connected to the oil tank input pipe through the oil outlet. The oil cooler has oil cooling channels and ventilation chambers inside, and heat dissipation fins are welded to the outer surface of the oil cooler.
[0006] Furthermore, the transformer body has an oil tank output pipe and an oil tank input pipe distributed vertically on one side; and the oil tank output pipe and the oil tank input pipe are connected to the oil tank pipeline inside the transformer body.
[0007] Furthermore, the oil inlet and oil outlet are staggered on the upper and lower end faces of the oil cooler; and the oil inlet is connected to the oil outlet through an oil cooling channel.
[0008] Furthermore, the oil cooling channels are S-shaped and distributed inside the oil cooler, with the heat sink and ventilation cavity located at the front and rear ends of the oil cooling channels, respectively.
[0009] Furthermore, dustproof mesh plates are fixed at the left and right openings of the ventilation cavity; and the ventilation cavity is an arc-shaped channel.
[0010] Furthermore, the ventilation cavity inner wall is welded with support blocks at equal intervals, and the outer surface of the oil radiator is convex in an arc shape.
[0011] Furthermore, heat dissipation fins are symmetrically installed on the left and right outer shell surfaces of the transformer body, and the side end of the oil cooler is fixed to the transformer body shell by fixing studs.
[0012] The beneficial effects of this utility model are that the transformer radiator structure utilizes the S-shaped oil cooling channel, ventilation cavity, and heat sink inside the oil radiator, allowing the oil output from the transformer to enter the S-shaped oil cooling channel. The heat of the oil is conducted and dissipated outward through the ventilation cavity and heat sink on both sides of the S-shaped oil cooling channel, realizing a double-sided heat dissipation transformer radiator structure. This effectively increases the heat dissipation area and heat dissipation flow path, facilitates and accelerates the heat dissipation of the transformer radiator, and improves the heat dissipation performance of the transformer radiator structure.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a transformer radiator structure, including an oil tank output pipe 2 and an oil tank input pipe 3. The oil tank output pipe 2 and the oil tank input pipe 3 are connected to both the front and rear sides of the transformer body 1.
[0019] Oil coolers 4 are symmetrically fixed on the front and rear ends of the transformer body 1. The upper end of the oil cooler 4 is connected to the oil tank output pipe 2 through the oil inlet 43, and the lower end of the oil cooler 4 is connected to the oil tank input pipe 3 through the oil outlet 44. The oil cooler 4 has an oil cooling channel 45 and a ventilation cavity 46 inside, and heat dissipation fins 5 are welded on the outer surface of the oil cooler 4.
[0020] When the transformer body 1 sends oil through the oil tank output pipe 2 into the S-shaped oil cooling channel 45 of the oil radiator 4, the heat of the oil is conducted and dissipated outward through the ventilation chambers 46 and heat sinks 5 on both sides of the S-shaped oil cooling channel 45, and then flows back into the transformer body 1, thus realizing a double-sided heat dissipation transformer radiator structure, effectively increasing the heat dissipation area and heat dissipation flow path, facilitating and accelerating the heat dissipation of the transformer radiator, and improving the heat dissipation performance of the transformer radiator structure.
[0021] In this embodiment, an oil tank output pipe 2 and an oil tank input pipe 3 are distributed vertically on one side of the transformer body 1; and the oil tank output pipe 2 and the oil tank input pipe 3 are connected to the oil tank pipeline inside the transformer body 1.
[0022] As a preferred implementation, the oil tank output pipe 2 and the oil tank input pipe 3 facilitate the delivery of hot oil to the oil radiator 4, where it is cooled before being returned to the internal oil tank of the transformer body 1, thereby cooling the interior of the transformer body 1.
[0023] In this embodiment, the oil inlet 43 and oil outlet 44 are staggered on the upper and lower end faces of the oil cooler 4; and the oil inlet 43 is connected to the oil outlet 44 through the oil cooling channel 45. The oil cooling channel 45 is S-shaped and located inside the oil cooler 4, with the heat sink 5 and ventilation cavity 46 located at the front and rear ends of the oil cooling channel 45, respectively. Dustproof mesh plates 41 are fixed at the left and right openings of the ventilation cavity 46; and the ventilation cavity 46 is an arc-shaped channel. Support blocks 47 are welded equidistantly to the inner wall of the ventilation cavity 46, and the outer surface of the oil cooler 4 is arc-shaped and convex.
[0024] As a preferred embodiment, the oil inlet 43 and the oil outlet 44 facilitate the introduction of oil passing through the transformer body 1 into the oil cooling channel 45. When the oil flows along the oil cooling channel 45, it is conducted and dissipated through the heat sink 5 and the ventilation cavity 46 on both sides, which effectively increases the heat dissipation area and heat dissipation flow path, facilitates the acceleration of heat dissipation of the transformer radiator, and improves the heat dissipation performance of the transformer radiator structure.
[0025] In this embodiment, heat dissipation fins are symmetrically installed on the left and right outer shell surfaces of the transformer body 1, and the side end of the oil cooler 4 is fixed to the shell of the transformer body 1 by fixing studs 42.
[0026] In a preferred embodiment, the heat dissipation fins increase the heat dissipation area of the transformer body 1, promote airflow, and thus accelerate heat dissipation. The oil radiator 4 is used to dissipate heat from inside the transformer body 1.
[0027] The transformer radiator structure of this utility model can effectively solve the problem in the prior art where impurities blocking the gaps between the heat sink fins on the side of the transformer cause obstruction of heat dissipation in the connection of a certain oil pipe, thus affecting the heat dissipation performance. It realizes a double-sided heat dissipation transformer radiator structure, effectively increasing the heat dissipation area and heat dissipation flow path, facilitating and accelerating the heat dissipation of the transformer radiator, and improving the heat dissipation performance of the transformer radiator structure. It is applicable to transformer radiator structures.
