The shell 14 has reinforcing ribs 12 on both sides, and is integrally formed with the mounting base plate 13 by die casting, so that the shell is firm and durable, and the left and right shells have a heat dissipation function.
The whole water-cooling aluminum cable coil 1 is wound by adopting a water-cooling aluminum cable pipe, is provided with a hollow water-cooling pipeline, is insulated by using crosslinked polyethylene at the outside, and is internally and externally provided with a shielding layer, so that the electric field intensity of the water-cooling aluminum cable coil 1 is uniformly distributed.
All parts in the product are molded by one-step casting by using epoxy resin or polyurethane elastic materials, and all parts are tightly connected to firmly wrap the coil and the iron core. The full-sealing structure mode enables the coil and the iron core to be completely isolated from the outside, and avoids the adverse effect of the outside on the main coil structure part.
And a vertical mounting structure is adopted, so that the heat dissipation surface of the product is increased, and the heat dissipation of the iron core and the coil is facilitated.
