本発明は電子管陽極円筒軸ｌこ平行な面をもつ縦吹き冷
却型マグネトロンに係り、特にラジェータフィン構造に
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.
従来の縦吹き冷却型マグネトロンは＃ｉｌＥに示すよう
な構造よりなる。すなわち、ラジェータフィン１は外周
部のエアダクト２を介してバンド３によって締め付けら
れ陽極円筒（図示せず）との熱接触を得る。図中、４は
上板、５は下板を示す。A conventional vertically blown cooled magnetron has a structure as shown in #ilE. That is, the radiator fin 1 is tightened by 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.
しかしながら、ラジェータフィンｌは第２図に示すよう
に平板を単に折曲げた形状よりなるので、バンド締付時
、ラジェータフィン１は円周方向に力を受け、ラジェー
タフィン同志が密着してしまう。この結果、密着したと
ころｌこは冷却風が通らず、冷却性能を劣化させる欠点
をもっていた。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, when they were in close contact, cooling air could not pass through them, resulting in a 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図により説明する。なお
、９１図と同じｒたは相当部材には同一符号を付しその
説明を省略する。ラジェータフィン１の外周部に隣接す

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 reference numerals as in FIG. 91 or equivalent members are given the same reference numerals, and the explanation thereof will be omitted. A protrusion 1a protruding toward 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ｌζ、ラジェータフィンｌに突起１ａを設けて
なるので、バンド３１＃付けなどによる片寄りが防止さ
れるので、ラジェータフィン間隔が均一化し、また密着
をも防止でき、ラジェータフィ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 protrusion 1a is provided on the radiator fin l, it prevents the radiator fin from shifting due to attachment of the band 31#, etc., making the radiator fin spacing uniform and preventing close contact, maximizing the radiator fin surface area. Can be used effectively and improves cooling efficiency.
ここで、下、［５に隣接したラジェータフィン１の突起
１ａは下板５側に形成すると、ラジエータフイ／１は下
板５への接触が非常に小さくなるので、下マグネット（
図示せず）への熱伝導を少なくすることができる。Here, if the protrusion 1a of the radiator fin 1 adjacent to the lower [5 is formed on the lower plate 5 side, the contact of the radiator fin/1 with the lower plate 5 will be very small, so the lower magnet (
(not shown) can be reduced.

フトの面で効果がある。According to the present invention, the radiator fin spacing is made uniform, the cooling surface area can be obtained as effectively as possible, and the wind pressure is made uniform, so that better cooling can be achieved. In addition, heat conduction from the lower plate to the lower magnet is reduced, which is effective in terms of cooling efficiency and drift.
