Currently, transformers are essential devices in life and industrial production, and the existence of transformers is becoming more and more important. While emphasizing functionality, the structural rationality of transformers also needs to be considered. The design and use of transformers are particularly important, as they can convert the AC and high-voltage mains power commonly used in external circuits into low-voltage DC power for small power devices.

[0003] Because the transformer generates a lot of heat in actual working process, most of the existing transformers use natural cooling or thermal conductive glue or add a cooling device. The natural cooling effect is poor. Adding a cooling device to the outside of the transformer increases the overall area of the transformer, resulting in a large occupied space for the transformer and the cooling device, which is not conducive to the use of small products. In the design of thermal conductive glue, the thermal conductive glue is arranged between the magnetic core and the coil. The existing transformer generally uses PQ type magnetic core assembly, which forms a chamber with an upper and lower opening. The coil winding is exposed from the opening, and the thermal conductive glue is arranged inside the chamber and exposed outside from the opening, which makes the thermal conductive glue prone to damage, reduces the heat dissipation performance of the transformer, and thus reduces the service life of the transformer, and has a small application range.
