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. The co-extrusion process is modified such that the side and upper walls are self-formed either while flowing inside a co-extrusion printhead, or immediately upon exiting the printhead.
