transformer
By employing internal and external coil units in the transformer, the exposed area of the secondary side is increased, solving the problems of heat dissipation difficulties and high manufacturing costs. This achieves more efficient heat dissipation and cost reduction, while also improving the balance of components.

AI Technical Summary
Existing transformers suffer from problems such as heat dissipation difficulties, high manufacturing costs, and insufficient component balance in terms of performance improvement.
The design employs internal and external coil units, with the internal coil unit located inside the core unit and the external coil unit partially located outside the core unit. At least 50% of the outer surface area of the external coil unit is exposed outside the core unit, eliminating the need for an external coil frame, increasing the exposed area on the secondary side to improve heat dissipation characteristics, and enhancing the balance of the components through a symmetrical design.
This improved the transformer's heat dissipation performance, reduced manufacturing costs, ensured appropriate leakage inductance, and enhanced component balance and manufacturing process feasibility.
