摘要： A magnetron includes: an anode tube; and cooling fins placed on a periphery of the anode tube, and arranged along a central axis of the anode tube. Each of the cooling fins includes at least two sets of fins formed by cutting a part of the cooling fin, and performing different bending works on the cut portions, respectively, so as to form a region where the cooling fins are dense and a region where the cooling fins are sparse, when viewed in a flowing direction of a cooling medium which cools the anode tube through the cooling fins. The at least two sets of fins are bent at bending angles such that intervals of the cooling fins in the region where the cooling fins are dense are ½ or less of placement intervals of the cooling fins.

摘要翻译： 磁控管包括：阳极管; 以及放置在阳极管的周边上并沿着阳极管的中心轴布置的散热片。 每个散热片包括至少两组翅片，其通过切割冷却翅片的一部分而形成，并且分别对切割部分进行不同的弯曲加工，以形成冷却翅片致密的区域， 当冷却介质通过冷却翅片冷却阳极管的冷却介质的流动方向时，散热片是稀疏的。 至少两组翅片以弯曲角度弯曲，使得冷却翅片致密区域中的冷却翅片的间隔为冷却翅片的放置间隔的1/2或更小。
