  • Publication number: 20050145368
    Abstract: A heat pipe structure, having a tubular member, a support member and a wick structure. The tubular member is hollow to accommodate the support member and the wick structure therein. The wick structure is located between the tubular member and the support member. The wick structure is supported by the support member to be attached to an interior wall of the tubular member. The material melting point of the wick structure is lower than those of the tubular member and the support member. Therefore, the support member maintains good supporting function during sintering process, such that the wick structure can be adequately attached to interior wall of the tubular member.

  • Publication number: 20050051301
    Abstract: A circular tubular heat pipe has a sealed structure closing a distal opening thereof. The improvement of the sealed structure provides a concave wall portion formed on the heat pipe adjacent to the distal opening. A pressed recess portion is formed on the concave wall portion adjacent to the distal opening, the heat pipe being formed to have a overlapping wall at the pressed recess portion. A volume reduced portion is formed on the pressed recess portion adjacent to the distal opening. A sealed welding portion is formed on the volume reduced portion at the distal opening, thereby reducing an area of the sealed welding portion. As the formation of the pressed recess portion and the volume reduced portion reduces the area of the sealed welding portion, the shrinking process is eliminated, and the welding time of the heat pipe with a large diameter is shortened.

  • Publication number: 20050051305
    Abstract: A heat pipe has a hollow pipe body, a wick structure of screen mesh disposed on an internal wall of the pipe body and at least one support structure extended to press the wick structure of screen mesh tightly to the internal wall of the pipe wall. The support structure spiral in shape, and is formed by a continuous board. The support structure provides a support force to support the wick structure of screen mesh on the internal wall of the wick structure of screen mesh by a surface of the spiral board. The heat pipe provides capillary action.
