本発明はヒートパイプに関し、さらに詳しくは重力式（
熱サイフオン式）のヒートパイフッ改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat pipe, and more particularly to a gravity heat pipe (
Regarding the improvement of the heat pipe (heat siphon type).
ヒートパイプにはウィックを設けるものと、パイプ内面
に例も設けない重力式とがあるが、近来重力式が主流と
なっている。There are two types of heat pipes: those with a wick and those with a gravity type that do not have a wick on the inner surface of the pipe, but recently the gravity type has become the mainstream.

。Conventional gravity heat pipes heat the medium in the heat receiving part, and the medium evaporates and is transferred to the heat radiating part, and the heat transfer U- in the heat receiving part is not very large. On the other hand, the type with a wick is one in which a wick is attached to the entire inner surface of the heat pipe, and the medium condensed in the heat dissipation part is transferred to the heat reception part using capillary action.
It is expensive and requires less heat transport.

１ゆ膜を設けたところにある。The feature of the present invention is that the heat transfer in the heat receiving part is carried out by boiling heat transfer, and the heat receiving part has porous inner surfaces.
It is located where a 1-yu membrane is installed.
以下、図によって説明する。This will be explained below using figures.

温度を云うものではない。The heat receiving part 3 is heated by the heat of the outside ψ1j, and is selected so that boiling occurs when heat is transferred to the medium 4 through the heat receiving part 3. This boiling phenomenon occurs at the boiling point of medium 4.・Since it depends on the pressure inside the pipe 1, the boiling point and t mentioned here do not refer to a fixed temperature.

。気泡６へは云熱面３からＱｌの如く熱が与えられる。Furthermore, by providing the boiling film 5, the growth of bubbles as shown in FIG. Air bubbles 6 are generated in the recesses surrounded by the heating surface 3 and the boiling film 5. Heat is applied to the air bubbles 6 from the heating surface 3 as indicated by Ql.
一方気泡６の周面からはＱ２の如く媒体４が蒸発Ｑ２に
よって多用の熱が気泡６内へ伝達される。このようにし
て気泡６は成長し、破壊されて上昇する。On the other hand, a large amount of heat is transferred from the circumferential surface of the bubble 6 into the bubble 6 by the evaporation Q2 of the medium 4 as shown in Q2. In this way, the bubbles 6 grow, are destroyed, and rise.
上記現象は沸ｊｈ熱伝達の通常現象であシ、詳述はさけ
