Abstract
A magnetic integrated structure comprises a magnetic core, a first framework, a transformer winding and an inductor winding. The magnetic core comprises a magnetic cover, and a middle column and an inductance column which are arranged on the magnetic cover; the air gap is located on the center pillar. The first framework is arranged on the middle column. The middle column penetrates through the first hollow part of the first framework. In the second direction, the first framework comprises two oppositely-arranged first open holes. The transformer winding is at least partially wound on the first framework. The inductor winding is wound on the inductor column. And in the third direction, the two first open pores and the air gap are the same in height. The two first open holes and the air gap form a first heat dissipation channel in the second direction. A gap exists between the transformer winding and the inductor winding in the first direction. In the second direction, the gap forms a second heat dissipation channel. And in the second direction, air inlets and air outlets of the first heat dissipation channel and the second heat dissipation channel are formed in the two opposite sides of the magnetic cover. According to the magnetic integrated structure, the first heat dissipation channel and the second heat dissipation channel are arranged, so that the heat dissipation capability of the whole magnetic integrated structure is enhanced.
