    • PURPOSE:To obtain the heat pipe which is excellent in its heat transfer capacity and is flexible by a method wherein a wick consisting of a number of extremly fine carbon fibers are attached closely to the inner peripheral surface of a sealed metallic pipe. CONSTITUTION:A number of extremely fine carbon fibers 2 serving as the wick attached to the inner peripheral surface of the sealed metallic pipe 1 an outer covering and a stop means 3 for fixing the carbon fibers 2 closely to the inner peripheral surface of the metallic pipe 1. The metallic pipe 1 may be straight but when it is required to be made flexible, a corrugated pipe may preferably be used. With the above structure, it is possible to obtain a high capillary pressure and to minimized the loss of pressure of a liquid phase operating fluid flowing back to a heating section. Thereby, it is made possible to obtain the heat pipe which is excellent in its heat transfer capacity and is flexible due to the flexibility and elasticity of the carbon fibers.
    • 目的:为了获得传热能力优良的热管,其特征在于,将由多根极细碳纤维组成的灯芯紧密地安装在密封金属管的内周面上。 构成:作为附着在密封金属管1的内周面的芯的许多极细碳纤维2,外覆盖层和用于将碳纤维2紧密地固定在金属管的内周面上的止挡装置3 金属管1可以是直的,但是当需要制成柔性时,可以优选使用波纹管。 利用上述结构,可以获得高毛细管压力并且使流回到加热部分的液相工作流体的压力损失最小化。 由此,能够获得传热能力优异且由于碳纤维的柔软性和弹性而变得柔软的热管。
