Abstract
1342923 Making heat pipes RCA CORPORATION 13 May 1971 [18 May 1970] 14772/71 Heading B3A [Also in Division F4] A method of making a heat pipe includes cleaning its internal surface to remove contaminants preventing wetting of the surface and forming on the cleaned surface an anticontamination coating of material soluble in the working fluid at working temperature. Prior to assembly of the pipe, parts 13, 15, 17 of an envelope 11 and a capillary structure 23, all of stainless steel, are cleaned chemically and fired in a reducing atmosphere at 900‹ C. The surfaces to be internal in the pipe and the structure 23 are nickel plated and then re-fired at about 800‹ C. to remove contaminants deposited during plating. The structure 23 is then inserted in the member 13 and the end cap 15 is electron-beam welded in place. Mercury metal working fluid is added under an inert atmosphere, the cap 17 electron-beam welded in position and the assembled heat pipe evacuated at about 400‹ C., to clean the system further. Some dissolution of the nickel coatings takes place during this process and the mercury vapour formed is held in the envelope 11 by heating the end 19 of the cap 17 to about 800‹ C. Upon cooling, the end 19 is sealed to make the envelope 11 vacuum-tight. The heat pipe is now ready for use and in service the nickel is progressively dissolved by the mercury, which is preferably saturated with nickel when all the latter has dissolved. This gives optimum resistance to attack by the mercury and pumping efficiency. In an alternative embodiment, the wettable surfaces are of iron or nickel-iron alloys, in which case the initial firing may be performed in a high-vacuum atmosphere at 1000‹ C. or higher.
