Claim Text:
1. A heat pipe structure, comprising a hollow pipe body including: a first sealed end; a second sealed end; a vaporizing section, a condensing section and a reducing section being provided between the vaporizing section and the condensing section, all three sections being between the first sealed end and the second sealed end; the vaporizing section having a first outer surface and a first inner surface; the first outer surface having a first planar top side and a first planar bottom side to define a vaporizing section thickness extending the full length of the vaporizing section, and the first inner surface having a first wick structure formed thereon; wherein the first wick structure can be continuously or non-continuously arranged on or around the first inner surface to define a first flow channel in the vaporizing section; and the condensing section having a second outer surface and a second inner surface; the second outer surface having a second planar top side and a second planar bottom side to define a condensing section thickness extending the full length of the condensing section, which is smaller than the vaporizing section thickness defined by the first top side and the first bottom side of the first outer surface, and the second inner surface having at least a first side and a second side opposite to the first side; the condensing section being internally provided along a part of its length with at least one second wick structure, which is located between and connected to the first side and the second side of the second inner surface, so as to define at least one second flow channel in the condensing section between the first and the second side; and the second flow channel being communicable with the first flow channel; wherein the reducing section has a reducing flow channel and a reducing section thickness, the reducing flow channel being communicable with the first flow channel and the second flow channel, and the reducing section extends and reduces the thickness from the vaporizing section thickness to the condensing section thickness.
