トパイプの、作動性能を著しく阻害する問題があ−だ。The conventional structure and its problems In the case of the structural material of conventional water heat pipes, metal aluminum or aluminum alloy (hereinafter collectively referred to as aluminum), water and water react with each other. There is a problem in that the resulting hydrogen gas accumulates in the condensing section of the heat pipe, reducing the effective length of the heat pipe, thereby significantly impeding the operational performance of the water heat pipe.

Operation When operating with a warm box, during operation Q', container 2
Further, a boehmite film is formed on the alumite surface of the container 2 due to the effect of the triethanolamine added to the water hydraulic fluid 3, and the pinholes and cracks in the alumite film of the container 2 are sealed and repaired. The corrosion resistance is significantly improved compared to those that have undergone alumite treatment. Therefore, the corrosion reaction between the container 2 and the water hydraulic fluid 3 is suppressed, and there is no need to worry about non-condensable gas such as hydrogen gas generated by the corrosion reaction accumulating near the condensing section 4 of the water heat pipe 1, unlike in the conventional case. There is no deterioration in operating performance. In addition, if the container 2 is not anodized and the water actuator 83 to which triethanolamine is added is enclosed and sealed, a boehmite film is formed on the surface of the container 20 during operation, but normally the boehmite film is 1 to 2/l. However, the thickness of the boehmite film can be increased freely depending on the processing time.
