（作用）
密閉容器の内部に作動流体が内包された熱伝達素子の一
部分で熱が加えられると、その部分の作動流体が吸熱に
より気化して作動流体蒸気となる。(Operation) When heat is applied to a portion of the heat transfer element in which the working fluid is contained inside the closed container, the working fluid in that portion is vaporized by heat absorption and becomes working fluid vapor.
この蒸気が移動して外部から冷却されると液化して、そ
の際潜熱を放出する。液化した作動流体は、加熱されて
いる部分に還流してこの一連の状態変化が連続的に行わ
れて熱伝達素子として作用する。When this vapor moves and is cooled externally, it liquefies, releasing latent heat. The liquefied working fluid flows back to the heated portion, and this series of state changes occurs continuously to act as a heat transfer element.
この容器の内部に作動流体を吸着又は捕獲する性質を有
する素材が挿入されていると、作動流体の蒸発、還流が
円滑になり熱伝達が良好となる。すなわち、熱が外部か

材のために蒸発や還流が円滑で良好な熱伝達を行うもの
である。If a material that has the property of adsorbing or capturing the working fluid is inserted into the container, the evaporation and reflux of the working fluid will be smooth and heat transfer will be improved. In other words, when the heat transfer element is not in operation and no heat is applied from the outside, the space occupied by the heat transfer element is very small, and when it is in operation, the space occupied by the heat transfer element is very small due to the material having the property of adsorbing or capturing the working fluid inserted. It provides smooth evaporation and reflux and good heat transfer.

2 is inserted, and the working fluid 3 is in the container. In the heat transfer element constructed as described above, since the container is made of a lightweight and flexible material, the shape can be changed relatively freely, and heat can be transferred using the same conventional principle. Compared to the heat transfer element that moves the heat transfer element, the volume occupied by the heat transfer element when not in operation is very small. Furthermore, the inserted nonwoven fabric facilitates evaporation and reflux.
