  • Patent number: 9188395
    Abstract: The method of manufacturing heat pipe is disclosed to insert a center bar into a metal tube such that the center bar contacts a clearance area of the inner sidewall of the metal tube. Then, the method is to fill the interval between the center bar and the metal tube with powder for sintering. At last, the method is to perform a sintering, extract the center bar, inject working fluid, and close the metal tube. A heat pipe is therefore formed. Because of no sintered powder on the clearance area, the heat pipe can be bent at the clearance area without damaging the capillary structure formed by the sintered powder. The flow path of the working fluid is not interrupted or influenced, so the heat transfer efficiency can be maintained, which overcomes the decrement of the heat transfer efficiency of a bent heat pipe in the prior art.

    Abstract: A method for generating a microchannel heat pipe on a substrate surface includes co-extruding a primary material and a secondary material such that the primary material forms side walls that are spaced apart by the secondary material to form a composite structure. After the primary material hardens, the secondary material is removed, whereby the hardened primary material forms a pipe body structure having an elongated central channel defined between opposing end openings. A working fluid is then inserted into the elongated central channel, and sealing structures are then formed over both end openings to encapsulate the working fluid.
