Abstract

PURPOSE: To provide a method of regularly fabricating a heat pipe wick which comprises the steps of: printing a plurality of stripes by paste on the surface of a green sheet containing an inorganic powder, repeating the application of a paste or a green sheet thereon, and sintering the same.
CONSTITUTION: An organic binder is added to a ceramic powder consisting of for example, 90% of α-AI2O3, 6% of SiO2 and 4% of MgO, and the mixture is kneaded and extruded in the shape of a sheet and dried. On the thus prepared green sheet 1 there are printed stripes 2 forming a wick layer having a width of 150 microns and a thickness of 30 microns by a mixed paste consisting of 100 parts of fine granular carbon, 20 parts of a polyvinyl butyral resin, 10% of a plasticizer phthalic acid ester, and 50 parts of butyl carbitol, through a silk screen. After drying the green sheet, on the printed surfaces thereof there is applied and printed a paste consisting of 100 parts of a ceramic powder having a composition same as that of the ceramic green sheet 1, 6 parts of a polyvinyl butyl resin, 4 parts of an ester, and 30 parts of bitol at parts corresponding to the evaporating part 4 and condensing part 5 with opening parts 6 and 6a of a diameter of 120 microns. Then, the sheet is sintered at a temperature of 1550°C and at the holding time of 1 hour to fabricate a heat pipe having a hollow wick layer.
