  • Patent number: 7152671
    Abstract: A tube 101 is constituted by a pair of plates 111a, 111b which are fitted with each other in such a manner as to put an inner fin 101b between the plate 111a and the plate 111b. Differences in level 111c are formed on the second plate 111b, which fits inside, which differences in level each protrude inwardly by a distance equal to the thickness of the first plate 111a, whereby the outer wall surface of the tube 101 is made substantially level thereover. A gap which is formed between the outer wall surface of the tube 101 and a core plate, when the tube is passed through the core plate, can be as small as possible whereby the brazing properties can be improved.

  • Patent number: 7134485
    Abstract: A composite wick structure of a heat pipe which is applied with a tube circumferential surface contacted to a heat source includes a plurality of grooves and a sintered-powder layer. The circular grooves are formed on the internal sidewall of the tubular member. The sintered-powder layer filled in the grooves is attached to at least a portion of the internal sidewall of the tubular member. By the better capillary force provided by the sintered powder, the liquid-phase working fluid can reflow to the bottom side of the heat pipe quickly to enhance the heat transmission efficiency. Further, the problem caused by usage of an axial rod during the process of applying sintered powder can be resolved.

  • Patent number: 7124810
    Abstract: A heat pipe (20) includes a pipe (21), a wick (22) formed on an inner wall (23) of the pipe, and a working fluid (not shown) sealed in the pipe and soaked in the wick. The wick is formed by sintering nano-size metal powder disposed inside the pipe. First through holes (25) are defined in the wick in an evaporator section (20a) of the heat pipe. A central one of the first through holes is aligned along an axis 20c of the heat pipe, and other first through holes are parallel to the axis 20c. A second through hole (26) is defined in the wick in a condenser section (20b) of the heat pipe. The second through hole communicates with the first through holes, whereby the working fluid flows through the first and second through holes. These characteristics give the wick low thermal resistance, a high evaporator surface area, and high capillary force.
