An electronic transformer, also called an electronic power transformer, is an electronic device for transferring energy and converting power, and is also a common device in a circuit. Electronic transformers are typically made of magnetic cores, bobbins, copper wire, adhesive paper, and the like. Conventionally, a copper wire winding mode is adopted, a layer of copper wire is wound on the bottom layer of a framework from inside to outside to form a spiral coil, then pins of the copper wire are sleeved in an insulating sheath and led to a pin end, then a layer of insulating gummed paper is wound, a layer of coil is wound, then the pins of the copper wire are sleeved in the insulating sheath and led to the pin end, then a layer of insulating gummed paper is wrapped, and the process is repeated for multiple layers. In order to avoid noise caused by resonance of the electronic transformer and improve the insulation strength between turns of the coil, the coil needs to be soaked with varnish or insulating paint.

1. The electronic transformer can generate heat due to iron loss and copper loss, and the performance and technical indexes of the transformer are influenced. Conventionally, conduction heat dissipation is adopted. The heat dissipation path is from the inner copper wire to the insulating material, then to the outer copper wire and then to the outer magnetic core, and the heat is continuously increased through the circulation of multiple layers.

2. The electronic transformer has safety requirements on insulation strength, creepage distance, electrical spacing and the like, and is difficult to balance and meet the requirements due to the small space size in the magnetic core and the low window utilization rate. Especially, the design difficulty of creepage distance and insulation strength is large, the traditional electronic transformer is designed by adopting a framework to isolate a magnetic core, insulating adhesive tapes are arranged between layers, and the outside is wrapped by the insulating adhesive tapes. The purpose is exactly in order to lengthen creepage distance, but heat accumulation is difficult to dispel the heat.

3. The winding mode is to fully utilize the limited window area of the magnetic core, and the coil-to-coil and layer-to-layer are in a spiral cross shape and irregular shapes, so that the performance consistency is poor.
