本発明は電子管陽極円筒軸に平行な面をもつ縦

フイン構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertically blown cooled magnetron having a surface parallel to the cylindrical axis of an electron tube anode, and particularly to a radiator fin structure.

通らず、冷却性能を劣化させる欠点をもつてい
た。 A conventional vertically blown cooled magnetron has a structure as shown in FIG. That is, the radiator fin 1 is connected to the band 3 via the air duct 2 on the outer periphery.
to obtain thermal contact with the anode cylinder (not shown). In the figure, 4 indicates the upper plate and 5 indicates the lower plate. However, since the radiator fin 1 is formed by simply bending a flat plate as shown in FIG. 2, when the band is tightened, the radiator fin 1 receives a force in the circumferential direction, causing the radiator fins to come into close contact with each other. As a result, cooling air cannot pass through the areas in close contact, which has the disadvantage of deteriorating cooling performance.
本発明の目的は冷却効率向上を図ることができ
るマグネトロンを提供することにある。 An object of the present invention is to provide a magnetron that can improve cooling efficiency.
以下、本発明の一実施例を第３図により説明す

突出する突起１ａを第４図に示すように切起しに
より、または第５図に示すように折曲げにより形
成してなる。 An embodiment of the present invention will be described below with reference to FIG. Note that the same or equivalent members as in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted. A protrusion 1a protruding toward the side of the radiator fin 1 adjacent to the outer peripheral portion of the radiator fin 1 is formed by cutting and raising as shown in FIG. 4 or by bending as shown in FIG.
このように、ラジエータフイン１に突起１ａを
設けてなるので、バンド３締付けなどによる片寄
りが防止されるので、ラジエータフイン間隔が均
一化し、また密着をも防止でき、ラジエータフイ
ン表面積を最大限有効に使用でき、冷却効率が向
上する。 In this way, since the radiator tuff fin 1 is provided with the protrusion 1a, deviation due to tightening of the band 3 is prevented, so the radiator tuff fin spacing is made uniform, and close contact can also be prevented, making the radiator tuff fin surface area maximally effective. can be used to improve cooling efficiency.
ここで、下板５に隣接したラジエータフイン１
の突起１ａは下板５側に形成すると、ラジエータ
フイン１は下板５への接触が非常に小さくなるの
で、下マグネツト（図示せず）への熱伝導を少な
くすることができる。 Here, the radiator fin 1 adjacent to the lower plate 5
When the protrusion 1a is formed on the lower plate 5 side, the radiator fin 1 makes very little contact with the lower plate 5, so that heat conduction to the lower magnet (not shown) can be reduced.
本発明によれば、ラジエータフイン間隔が均一
化し、冷却表面積を最大限有効に得られ、しかも
風圧が均一化することにより、より良く冷却でき
る。また下板から下マグネツトへの熱伝導は少な
くなるので、冷却効率、ドリフトの面で効果があ
る。 According to the present invention, the spacing between the radiator fins is made uniform, the cooling surface area can be obtained as effectively as possible, and the air pressure is made uniform, so that better cooling can be achieved. Also, since heat conduction from the lower plate to the lower magnet is reduced, it is effective in terms of cooling efficiency and drift.
