    • A heat pipe wherein a condensable liquid phase working fluid is encapsulated in a container sealed in air-tight condition; wherein the wick composed of the porous body for refluxing the liquid phase working fluid by a capillary pressure is provided in the container; wherein a part of the container functions as an evaporating part for evaporating the working fluid by means of inputting the heat from outside; and wherein another part of the container functions as a condensing part for condensing a vapor of the working fluid by means of radiating the heat to the outside; comprises a direct reflux flow passage for flowing the liquid phase working fluid to the evaporating part, which has a flow cross-sectional area greater than that of a cavity formed in the porous body.
    • 一种热管,其中可冷凝液相工作流体被封装在密封在气密状态的容器中; 其特征在于,在所述容器内设置由所述多孔体构成的用于使所述液相工作流体回流的毛细管压力的芯, 其特征在于,所述容器的一部分作为用于通过从外部输入热量而使所述工作流体蒸发的蒸发部件发挥功能; 并且其中所述容器的另一部分用作通过将热量散发到外部而冷凝所述工作流体的蒸汽的冷凝部件; 包括用于将液相工作流体流动到蒸发部分的直接回流流动通道,该蒸发部分的流动横截面积大于在多孔体中形成的空腔的流动横截面面积。
