Process for producing heat pipe |
摘要 |
A process for producing a heat pipe including the steps of treating the inner surface of a steel container with an aqueous solution of a vanadate with heating, and enclosing in the container a working liquid prepared by adding an alkalinizing pH adjusting agent to pure water and having an adjusted pH of 8 to 12. When the container inner surface is treated with the aqueous vanadate solution with heating, a protective layer covering the inner surface is formed. The working liquid, when in the range of 8 to 12 in pH, maintains the protective layer in a stable state over a prolonged period of time.
