密封式模块电源的散热设计通常是非常棘手的课题，对于变压器来讲尤其如此。密封式模块电源通常是采用热传导方式进行散热，由于模块内部灌封胶通常无法完全包裹变压器，以及变压器磁芯的热阻较大，尤其是在磁芯的结合面，因此造成变压器贴基板一侧的底部磁芯温度与另一侧顶部温差很大，需要将顶部磁芯热量传导至基板。The thermal design of a sealed modular power supply is often a very difficult subject, especially for transformers. The sealed module power supply usually uses heat conduction to dissipate heat. Since the module's internal potting compound usually cannot completely wrap the transformer, and the transformer core has a large thermal resistance, especially at the bonding surface of the magnetic core, the transformer is attached to the substrate side. The temperature of the bottom core is very different from the temperature of the other side, and the heat of the top core needs to be conducted to the substrate.
