Transformer structure

By employing a square ring magnetic core structure in the transformer, and winding the secondary winding on the outside of the primary winding away from the magnetic core, the problem of poor heat dissipation of the secondary winding is solved, resulting in more efficient heat dissipation and more stable transformer performance.

AI Technical Summary

Technical Problem

The secondary windings of existing transformer devices generate severe heat due to high current, resulting in poor heat dissipation, low efficiency, and safety hazards.

Method used

The structure adopts a square ring magnetic core, with the secondary winding wound on the outside of the primary winding away from the magnetic core, which increases the heat dissipation area, optimizes the magnetic field distribution, and improves the smoothness of the heat dissipation channel.

Benefits of technology

It effectively dissipates heat from the secondary winding, prevents overheating, improves transformer efficiency and stability, reduces safety hazards, and is suitable for DC-DC transformer structures.

Abstract

Provided is a transformer (10) structure, comprising a square ring magnetic core (100) and windings. The windings comprise a first primary winding (200), a second primary winding (300), and a secondary winding (400). The first primary winding (200) is wound around a first region of the square ring magnetic core (100), the second primary winding (300) is wound around a second region of the square ring magnetic core (100), and the first region and the second region are arranged in the circumferential direction of the square ring magnetic core (100). The first primary winding (200) and the second primary winding (300) are spaced apart, and the secondary winding (400) is at least wound around part of outer sides of the first primary winding (200) and the second primary winding (300) away from the square ring magnetic core (100), thereby improving heat dissipation performance.
