Abstract

The invention provides a magnetic assembly and a power supply module and relates to the technical field of power electronics. The magnetic assembly comprises a first heat dissipation structure, a magnetic core extending in the transverse direction and a winding structure arranged on the magnetic core in a winding mode. The winding structure at least comprises a first winding package and a second winding package which are adjacently arranged in the transverse direction. A gap is formed between the first winding package and the second winding package; at least a part of the first heat dissipation structure is arranged in the gap; the first heat dissipation structure is in thermal contact with the first winding package, the second winding package and the magnetic core such that the first heatdissipation structure can help the magnetic core, the first winding package and the second winding package dissipate heat in the vertical direction and the longitudinal direction at the same time, the heat dissipation path is shortened, the thermal resistance is reduced, and the heat dissipation effect of the magnetic assembly is improved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a magnetic component and a power module. Background technique [0002] With the continuous development of switching power supply technology and the continuous development of various new energy power generation and electrical equipment, high-power power supply modules have become an obvious direction of development and demand; and with the increasing power demand, how to The heat dissipation of the magnetic components in the power module has become a research hotspot. [0003] The magnetic component may be a transformer or an inductor, which generally includes a magnetic core and multiple winding packages arranged on the magnetic core. The heat generated inside the magnetic component mainly comes from the heating of the magnetic core and the winding packages. The heat generated by the magnetic components is often dissipated by using a liquid-cooled heat dissipation cavi...
