A method of manufacturing a heat pipe 3 comprises deaerating a gas and filling a cavity (33, fig 13) of the heat pipe 3 with a working fluid 5 via an opening 32 on a flat surface 31 of the heat pipe 3, and compressing the heat pipe 3 perpendicular to the flat surface 31 to deform a part of the heat pipe 3 to seal the opening 32. Prior to filling the cavity (33), the working fluid 5 may be vaporized (fig 8). Working fluid 5 may be water, methyl alcohol or other liquids. Sealing the opening 32 comprises of moving a first 71 and/or second 72 loading element (figs 16 - 18), and soldering or spot welding the opening 32. Soldering techniques may include gas, supersonic or laser soldering. Gas is deaerated by mounting a sucking disk 61 onto opening 32 that comprises of a deformation part 611 having a through hole 612, which receives a pipe 62 for deaerating and filling the cavity (33). The method maintains air tightness during deaerating and filling and improves the quality of the heat pipe 3. |
