1 is refluxed from the condensing section 14 to the evaporating section I2, and the entire wick layer 7 of the evaporating section 12 is fitted with a metal lid at the tip of the heat pipe. This lid 1 is composed of a body 4 having four step-shaped parts in the center, and a disc-shaped disc 2 fitted into the four parts on the distal end side of the body 4. Note that the body 4. The disk 2 is made of different metals and forms a thermocouple.

At the rear end of the heat vibrator, an oval disk-shaped stabbing member IO is provided with a through hole in the center, and the rear end of the 7-space tube 8 is inserted into this through hole. Further, the sealing portion 10 is provided with a socket 15.

次に、前述した構造の熱流計の作用について説明する。Next, the operation of the heat flow meter having the above-described structure will be explained.
捷ず、熱流（矢印）が蓋ｌにあたると、ディスク２とボ
ディ４に起電力が光中し。When the heat flow (arrow) hits the lid 1 without being separated, an electromotive force is applied to the disc 2 and the body 4.
この起電力は一対のリード線５で取り出され。This electromotive force is taken out by a pair of lead wires 5.

トパイプの凝縮部１４をフィン９で冷却することにより
液化され、放熱が行なわれる。その結果、ヒートパイプ
の外筒６の先端側に位置するボディ４が冷却される。The heat flux is determined by the voltage signal 117. At the same time, due to the heat flow hitting the lid l, the heat receiving part (evaporation part 12) of the heat pipe near the lid l vaporizes and cools the working liquid 11 in the heat pipe, and furthermore, this vaporized working liquid 1.1 By cooling the condensing part 14 of the heat pipe with the fins 9, it is liquefied and heat is radiated. As a result, the body 4 located at the tip side of the outer tube 6 of the heat pipe is cooled.
しかして、前述した構造の熱流計によれば。According to the heat flow meter having the structure described above.
自然通風でヒートパイプを冷却できるため、従来装置の
如く冷却水や水槽を用いる必要がない。Since the heat pipe can be cooled by natural ventilation, there is no need to use cooling water or a water tank like in conventional devices.
まだ、同上の理由から、ヒートパイプの凝縮部１４の長
さが従来と比べて短縮してコンパクト化できるだめ、狭
い場所での使用が可能となる。However, for the same reason as above, since the length of the condensing section 14 of the heat pipe can be shortened and made more compact than in the past, it can be used in narrow spaces.
このようにヒートパイプを利用することによ−）て押々
の利点を得ることが可能ではあるものの１弱点も有して
いる。Although it is possible to obtain many advantages by using heat pipes in this way, it also has one drawback.
すなわち、一般のヒートパイプでは、熱入力がパイプの
側面から行なわれるが、上述したような熱流側に適用し

ディ４の熱除去が不充分となり、ボディ４が溶融したり

ドライアウトしたり、動作液ＩＩが発泡したりする不具
合がある。That is, in a general heat pipe, heat input is performed from the side of the pipe, but when applied to the heat flow side as described above, the heat input from the disk 2 is equal to the heat input from the side of the outer cylinder 6. In comparison, it is about 1 to 2 orders of magnitude larger. Unfortunately, if the heat input is large, heat removal from the body 4 will be insufficient, causing the body 4 to melt or the heat load to be concentrated locally, causing the operating fluid 11 to dry out near the body 4. There is a problem that the working fluid II may foam.

土げることが可能となる。The heat flow side where the pair of lead wires are connected to dissimilar metals of the lid, a wick layer is provided on the inner surface of the lid at the tip of the heat pipe, and the heat removal area is wide and wide. It becomes possible to suppress the temperature rise of the working fluid stored in the pipe, expanding the range of applications of the heat flow meter. Alternatively, a wick layer with a cooling effect is placed around the outer circumference of the sheath pipe, so there is no need to consider the heat resistance of the sheath pipe, and a sheath pipe that is compatible with the operating fluid can be selected, making it possible to improve the heat dissipation effect. becomes.
以下本発明を第２図に示す一実施例について説明するが
、符号１ないし１７を付したものの構造・作用は第１図
のものと同一であるので説明を省略する。The present invention will be described below with reference to an embodiment shown in FIG. 2, but the structures and functions of the components denoted by numerals 1 to 17 are the same as those in FIG. 1, so the explanation will be omitted.
図において＋０７はヒートパイプ先端のボディ４の冷却
面に配設され熱Ω除去をするウィック層である。In the figure, +07 is a wick layer disposed on the cooling surface of the body 4 at the tip of the heat pipe to remove heat Ω.
従−３て、熱流が高くヒートパイプとして作動の限度を
超すような状況下にあっても、入熱を除去するウィック
層＋０７がヒートパイプのボディ４への熱入力を制限す

が拡大する。Thirdly, even under conditions where the heat flow is high and exceeds the operating limit as a heat pipe, the wick layer +07, which removes heat input, limits the heat input to the body 4 of the heat pipe, allowing normal operation. can be obtained, expanding the range of application of the heat flow meter.
すなわち、熱流（矢印）が大きい場合にもボディ４が溶
融したり１部分的に熱負荷が集中し動作液１１がドライ
アラ上したり発泡したりする事などを防止しうる。That is, even when the heat flow (arrow) is large, it is possible to prevent the body 4 from melting or from concentrating the heat load on one part, causing the operating fluid 11 to dry up or foam.
第３図には９本発明の別の実施例が示してあり、その例
では／−ス管８の外周にも入熱を除去する筒状のライ、

A surrounding layer 207 is provided.
従って前記実施よりもさらにヒートパイプのディスク４

材をソース管８の構なお、ウィック層はボディ４の冷却
面とソース管８の外周に併設することによって熱除去に
効果がある訳で、／−ス管８の外周のみにウィック層を
配設したとしてもボディ４からの入熱洲が大きく、熱除
去効果を期待することはできない。Therefore, the disc 4 of the heat pipe is further
heat removal from the area is promoted. Since there is no need to use a heat-insulating protective material for the sheath tube 8, the structure of the source tube 8 is made of paulownia wood that is compatible with the working fluid, and a wick layer is provided on the cooling surface of the body 4 and the outer periphery of the source tube 8. Therefore, even if a wick layer is provided only on the outer periphery of the space pipe 8, the heat input from the body 4 will be large and no heat removal effect can be expected.
