成する方法がもっばらとられてきた。A large number of antennas are installed near the high-frequency electric field to capture unnecessary electromagnetic waves, extract them to the outside, and consume them as heat. Since such an antenna generates heat due to induction, it is necessary to cool it. However, the antenna is installed in a vacuum, and almost no heat transfer occurs other than through thermal conduction of the antenna itself.
In order to cool this antenna, conventionally the most common method has been to form a water channel inside the antenna.

必要とはしない。Since the antenna 1 according to the present invention is configured as a heat pipe as described above, the antenna 1 inside the high frequency cavity 10
The working fluid (not shown) in the heat collecting part A is evaporated by the heat generated by the antenna 1, moves to the heat radiating part B having a large number of heat radiating fins 2, 2, condenses and liquefies, and collects the heat again by gravity. It flows back to part A. By this operation, the antenna 1 is quickly cooled without requiring the water cooling mechanism or the like. Therefore, in the present invention, it is only necessary to adopt an extremely simple structure of sealing the working fluid inside the antenna 1, and the addition of water channels as in the conventional example is not required. Since there is no need to operate machines for circulation or filtration, it is not only possible to record the number of machining parts and equipment costs on paper, but also to ensure airtightness and eliminate problems such as welding and I7 connections. There is no such place, so please send a reliable fig.
In addition to directing the pipe toward +, the hydraulic fluid is kept in a stable state inside the pipe by one person, so no special maintenance is required.
