摘要：
本发明涉及变压器领域，本发明公开了一种具有导热结构的高频变压器，包括：磁芯(11、12)，所述磁芯(11、12)具有磁芯芯柱；绕组骨架(21、22)，所述绕组骨架(21、22)套在所述磁芯芯柱上；绕组(31、32)，所述绕组(31、32)缠绕在所述绕组骨架(21、22)上；以及导热结构，所述导热结构与所述绕组骨架(21、22)的多层相接合。本发明还对应公开了一种具有导热结构的高频变压器的制造方法。本发明能够显著减小变压器内部热路热阻，提升内部导热能力，降低变压器因绕组损耗与磁芯损耗而产生的内部温升，减小变压器内部温度峰化。
摘要（英）：

The present invention relates to the field of transformers, and discloses a high-frequency transformer with a heat conduction structure. The high-frequency transformer comprises magnetic cores (11, 12), wherein the magnetic cores (11, 12) have magnetic core columns; winding skeletons (21, 22), wherein the magnetic core columns are sleeved with the winding skeletons (21, 22); windings (31, 32), wherein the windings (31, 32) are wound on the winding skeletons (21, 22); and a heat conduction structure jointed with multiple layers of the winding skeletons (21, 22). The present invention also correspondingly discloses a manufacturing method of the high-frequency transformer with the heat conduction structure. Thermal path thermal resistance in the transformer can be significantly reduced, the internal heat conduction capability is improved, internal temperature rise of the transformer due to winding loss and magnetic core loss is reduced, and internal temperature peak of the transformer isreduced.
