劣化させるという問題があった。Prior Art and Its Problems For example, heat pipes in which water is sealed in an iron container are widely used because of the high strength of the container and the high performance of water as a working fluid. However, such a heat pipe has a problem in that iron and water react to generate hydrogen gas, which deteriorates the heat transfer performance of the heat pipe in a short period of time.

きない。In other words, the generated hydrogen gas diffuses within the container wall in an atomic state, and some of it is released outside the container at a constant rate, but most of it gradually accumulates in the condensation area inside the container and occupies the condensation area. This prevents the condensation of steam and leads to deterioration of the heat transfer performance of the heat pipe. Furthermore, since this deterioration progresses and increases at an accelerated rate over time, the life of the heat pipe is rapidly shortened as the usage time increases. Furthermore, the outer surface of iron containers may be aluminized for the purpose of imparting corrosion resistance and vacuum brazing of aluminum fins with a brazing layer, but containers that have been subjected to such treatment may Hydrogen gas that has diffused inside the wall is blocked by the formed aluminized film and cannot exit the container.

た。Therefore, in order to prevent the generation of hydrogen gas as described above and the performance deterioration of heat vibrators due to the generation of hydrogen gas, the condensing part of the container was made of palladium, which has good hydrogen permeability. (See Publication No. 49064),
Alternatively, by inserting a palladium wire into the condensation part of the container (see Utility Model Publication No. 142/1982), hydrogen gas accumulated inside the heat vibrator can be discharged to the outside of the heat vib through the palladium. things are provided. However, in such a heat vibrator, the permeation and discharge of hydrogen gas cannot keep up with the increased generation of hydrogen gas when used at high temperatures, and it is not only impossible to completely prevent deterioration of heat transfer performance. However, there was a problem in that the manufacturing cost was high because expensive palladium was required.

Although it is excellent in suppressing performance deterioration, it cannot be said that it is easy to manufacture because it requires modification to place the oxidizing agent inside the container, and the manufacturing cost is also high. be.

することができる。Effects of the Invention According to the heat vibrator of the present invention, a wick having the property of oxidizing hydrogen gas and returning it to water is disposed at least in the condensing part, so that water, which is the working fluid, reacts with the container and generates hydrogen. Even if gas is generated, this hydrogen gas is oxidized by the wick and returns to water. Therefore, deterioration of the heat transfer performance of the heat vibrator due to the generated hydrogen gas can be suppressed.
