(Akira Jitsuka
(See Publication No. 59-13876) (Problems to be Solved by the Invention) However, in the above-mentioned known heat pipe type heat exchanger, since the inside of the heat transfer tube and the fins are closed, the closed wall prevents heat transfer. The problem was that the heat transfer rate was not good.

ばフインの大形化がさけられなかつた。 Moreover, in the above-mentioned known fins, heat is radiated (heat absorbed) at the tip side of the fin, and heat is absorbed (heat radiated) at the base side of the fin, so only a part of the fin is used for heat radiation (or heat absorption). I haven't. For this reason, in order to obtain a large amount of heat exchange, it was necessary to increase the size of the fins.
そこで、本発明の目的は、フインの全体を熱伝

にある。(Means for Solving the Problems) The present invention is characterized by a fin provided in a heat exchanger tube through which a gas-liquid two-phase flow flows, and a fin formed inside the fin and communicating with the inside of the heat exchanger tube. The heat transfer tube consists of a heat pipe space formed by a fin and a wick provided on the inner wall of the heat pipe space, and heat is exchanged between the tip of the fin and the inside of the heat transfer tube.
（実施例）
以下、図によつて本発明の一実施例について声

管内２に連通されており、さらにヒートパイプ空
間４の内壁にはウイツク５が設けられている。 The heat transfer tube 1 is provided with disk-shaped fins 3, and a heat pipe space 4 is formed inside the fins 3. The heat pipe space 4 is communicated with the inside 2 of the heat transfer tube 1, and a wick 5 is provided on the inner wall of the heat pipe space 4.
加熱媒体はＧのように流れてフイン３に熱を与
えている。 The heating medium flows like G and gives heat to the fins 3.
（作用）

れて送られる。(Function) The liquid flowing inside the heat transfer tube 1 is sent to the vicinity of the tip of the heat pipe space 4 due to the capillary action of the tube 5. The fins 3 are heated by a heating medium to a high temperature, and the liquid that has penetrated into the wick 5 is evaporated. The evaporated liquid is sent into the pipe 2, where it is cooled and liquefied, or mixed into a two-phase flow and sent.
なお、フイン３の加熱は、フイン３の全面で行
なわれるものとなつている。 Note that the heating of the fins 3 is performed over the entire surface of the fins 3.
以上の説明では、フインの形状を円盤状として

薄い空間であることが望ましい。 Note that it is desirable that the heat pipe space formed in the fin be a thin space.
（発明の効果）
以上のように構成された本発明の効果は次のと
おりである。(Effects of the Invention) The effects of the present invention configured as described above are as follows.
フインに与えられた熱がウイツクに浸透してい

が一定となる上、フイン全面で熱交換を行なうも
のとなり、フインの大きさを任意の大きさとして
もその大きさに見合う熱伝達を行なうものとな
る。このため、従来のフインと比べて熱伝達率を
向上させることができるものとなる。 The heat applied to the fins evaporates the liquid that has permeated the wick, so the temperature distribution throughout the fins is constant, and heat exchange occurs over the entire surface of the fins. It also provides heat transfer commensurate with its size. Therefore, the heat transfer coefficient can be improved compared to conventional fins.
ヒートパイプ作用を利用するものであるから、
小形で大容量の熱輸送ができ、低温度差の熱授受
に効果的である。 Because it uses heat pipe action,
It is small and can transport a large amount of heat, and is effective in transferring heat at low temperature differences.
