Abstract
A capacitor structure and a power convertor are provided by the present disclosure. The capacitor structure includes a housing and at least one core arranged inside the housing, and two electrodes of the capacitor structure are respectively led out from two ends of the housing. Thus, the pole piece required in a case that electrodes are led from the same end of the housing is omitted, thereby saving material cost. Besides, the housing and the core are respectively hollow structures, and the internal heat of the capacitor structure can be ventilated and dissipated through the corresponding hollow part, thereby improving the heat dissipation performance of the capacitor structure. In addition, by arranging the fin heat dissipation teeth on the housing, the heat dissipation area can be increased to further improve the heat dissipation efficiency.
