FIG. 5 shows the flow path of the forced air cooling airflow in a conventional magnetron device, where the forced air cooling airflow 2 flowing between the plates of the heat dissipation vanes 1 flows on both sides in the vicinity of the anode cylinder 3 of the magnetron. Because the flow is largely divided into
There was a problem in that it was difficult to efficiently cool the anode cylinder, which is the highest temperature. In addition, 4 in the figure shows the cylindrical part for penetrating the anode cylinder of the heat radiation vane plate 1, and 5 shows the side wall part of the frame-shaped yoke.

The shortest distance between the cylindrical part formed in the horizontal wing part and passing through the anode cylinder and the vertical wing part is set to 10 to 3 of the outer diameter of the cylindrical part.

能となる。Function: Due to this configuration, the forced air cooling air flow that enters the radiator is divided to both sides near the anode cylinder of the magnetron, but since the vertical blades act as partition walls, the deflection of the divided flow is reduced. The corners are narrowed and the air flows around the back side of the anode cylinder.In other words, the air cooling airflow hits the anode cylinder and the radiator near it more, making it possible to efficiently air-cool the magnetron. It becomes possible.

Each horizontal blade part 8 of the radiator 7 is arranged in multiple stages via a forced air cooling air flow passage, and each horizontal blade part 8 is formed with a cylindrical part 9 for penetrating the anode cylinder of the magnetron 6. has been done. Further, a pair of vertical wing sections 10 that bridge the horizontal wing sections 8 to each other are provided between the horizontal wing sections, and the shortest distance A between the cylindrical section 9 and the vertical wing section 10 is determined by the outer side of the cylindrical section 9. The diameter is 10 to 30% of the diameter B.

can be obtained relatively inexpensively by forming by press working. Note that one magnetic pole part 1 of the magnetron 6
An annular permanent magnet (not shown) is coaxially stacked on top of the magnet 1, and the outer magnetic pole of this magnet is magnetically coupled to the outer magnetic pole of another annular permanent magnet 13 through the frame-shaped yoke 12. The inner magnetic pole of the magnet 13 is magnetically coupled to the other magnetic pole part of the magnetron 6.

とができる。As shown in FIG. 3, among the forced air cooling airflow 14 flowing between the horizontal blades 8 of the radiator 7, a pair of vertical blades 10
．． Those that enter between 10 and 10 are divided to both sides near the anode cylinder of magnetron 6.
Due to the partitioning effect of the anode, it does not deflect to both sides to a great extent, but instead travels at a high density through the narrow portion between the anode cylinder and the vertical wing portion 10, and then changes its direction significantly inward. Therefore, the entire circumference of the anode cylinder of the magnetron 6 and the radiator portion in the vicinity thereof can be better air-cooled. In addition, the vertical wing portion 10
The air cooling air flowing between the side wall of the frame-shaped yoke 12 travels straight along the vertical wing section 10, and the radiator section in this region is also appropriately air-cooled, so that the heat dissipation area by the vertical wing section 10 is Coupled with the expansion of , a good heat dissipation effect can be obtained.

得られな（なる。When the shortest distance A between the cylindrical portion 9 and the vertical wing portion 10 becomes less than 10% of the outer diameter B of the cylindrical portion 9, the air resistance at the shortest distance A increases and air flows between the pair of vertical wing portions 10, 10. This causes a decrease in the airflow for cooling. Furthermore, if the shortest distance A exceeds 30% of the outer diameter B, the effect of narrowing the deflection angle as described above cannot be obtained.

。Figure 4 shows the < A/B value - anode cylinder temperature characteristic based on the experimental results, and from this, A/B = 10 to 30% (for example, B value at A = 40 mm is 4III11 to 12
II1m), the anode cylinder temperature can be lowered by 15 to 25°C compared to the conventional one (B = about 25mm), and A/B = 1
It can be seen that when the temperature is between 5% and 25%, it can be reduced by about 25 aC.
