Example 1

The embodiment provides a multi-pipeline oil-immersed transformer, as shown in fig. 1-6, including transformer main body 1, the side of transformer main body 1 is welded closely with a plurality of circulation pipelines 11 that are rectangular plate-like structures, tube cavity 111 has been seted up to circulation pipeline 11's inside, the first and last both ends of tube cavity 111 are linked together with the inside upper and lower both sides of transformer main body 1 respectively, when transformer oil in transformer main body 1 circulates, transformer oil gets into and discharges from the other end from one end of tube cavity 111, make the heat conduction that carries in the transformer oil to in the circulation pipeline 11, increase transformer oil's radiating effect.

In this embodiment, the side surface of the circulation pipeline 11 is provided with a hollow groove 112, and the tube cavity 111 is located at the periphery of the hollow groove 112, so as to facilitate the dissipation of heat conducted to the circulation pipeline 11, thereby achieving the purpose of heat dissipation.

Specifically, one side of the transformer main body 1 on which the circulation pipeline 11 is arranged is further provided with a heat dissipation mechanism 2, the heat dissipation mechanism 2 comprises a bottom frame 21 fixed at the bottom position of the side end of the transformer main body 1 through a bolt and an outer cover plate 22 tightly welded to the top end of the bottom frame 21, a fan 211 is installed on the inner side of the bottom frame 21 through a bolt, the outer cover plate 22 is bent and covers the circulation pipeline 11, a wind gathering cover 212 is arranged between the bottom frame 21 and the outer cover plate 22, two ends of the top and bottom of the wind gathering cover 212 are respectively tightly welded to the outer cover plate 22 and the bottom frame 21, when the fan 211 is connected with an external power supply, the fan 211 starts to work and blows towards the circulation pipeline 11, cold air is sucked by the fan 211 and then blows towards the circulation pipeline 11, and when heat dissipated by the circulation pipeline 11 is taken away, the cooling effect is.
