本発明は、液体弾管路を有する還流ヒートパイプは還流管の液体部位の内部が分割されて形成した小口径の管路によって液体作動液に液体弾を生成させるため、液体作動液は毛管力がない状態で還流管内部の圧力差によって液体弾を前進させることによって蒸発チャンバーにスムーズに還流できる、液体弾管路を有する還流ヒートパイプを提供することを主な目的とする。   According to the present invention, a reflux heat pipe having a liquid bullet path generates a liquid bullet in the liquid hydraulic fluid by a small-diameter pipe formed by dividing the inside of the liquid portion of the reflux pipe. The main object of the present invention is to provide a reflux heat pipe having a liquid bullet path that can smoothly flow back to the evaporation chamber by advancing the liquid bullet due to the pressure difference inside the reflux pipe in the absence of the liquid.

本発明は、液体弾管路を有する還流ヒートパイプは還流管の液体部位にメッシュ状脈管または毛細管材などを配置する工程がないため、製造コストを削減し、歩留まりを向上させることができる、液体弾管路を有する還流ヒートパイプを提供することをもう一つの目的とする。   In the present invention, since the reflux heat pipe having a liquid bullet path does not have a step of arranging a mesh-like vascular tube or a capillary material in the liquid portion of the reflux tube, the manufacturing cost can be reduced and the yield can be improved. It is another object to provide a reflux heat pipe having a liquid bullet channel.

上述した課題を解決するための、液体弾管路を有する還流ヒートパイプは蒸発チャンバー、還流管および作動液を備える。
蒸発チャンバーはハウジングおよびハウジング内に配置された毛細管材を有する。毛細管材はハウジングに充満せず、ハウジングとの間に蒸気空間を形成する。還流管は一端が気体端となり、別の一端が液体端となる。還流管の気体端はハウジングに接続され、その空間に繋がる。還流管の液体端はハウジングに接続され、ハウジングの内部に繋がる。作動液は蒸発チャンバーに注入される。還流管は長さが所定の部位が冷却部位となり、冷却部位から気体端までの部分が気体部位となり、冷却部位から液体端までの部分が液体部位となる。放熱部材は冷却部位の表面に配置される。還流管の液体部位は内部の少なくとも一つのスペーサーによって二つ以上の液体弾管路に分割される。二つ以上の液体弾管路は相互に繋がらず、それぞれ冷却部位およびハウジング内部に繋がり、口径が還流管の口径より小さい。 In order to solve the above-described problems, a reflux heat pipe having a liquid bullet path includes an evaporation chamber, a reflux pipe, and a working fluid.
The evaporation chamber has a housing and a capillary material disposed within the housing. The capillary material does not fill the housing, and forms a vapor space with the housing. One end of the reflux tube is a gas end, and the other end is a liquid end. The gas end of the reflux tube is connected to the housing and connected to the space. The liquid end of the reflux pipe is connected to the housing and is connected to the inside of the housing. The working fluid is injected into the evaporation chamber. In the reflux pipe, a part having a predetermined length is a cooling part, a part from the cooling part to the gas end is a gas part, and a part from the cooling part to the liquid end is a liquid part. The heat radiating member is disposed on the surface of the cooling site. The liquid portion of the reflux pipe is divided into two or more liquid bullet paths by at least one spacer inside. Two or more liquid bullet paths are not connected to each other, but are connected to the cooling portion and the inside of the housing, respectively, and the diameter is smaller than the diameter of the reflux pipe.

上述したとおり、本発明は還流管の液体部位の内部を小口径の管路に分割することによって液体作動液に液体弾を生成させる効果を生じるため、液体作動液は毛管力がない状態で還流管内部の圧力差によって液体弾を前進させる形で蒸発チャンバーまで還流することができる。
本発明は還流管の液体部位にメッシュ状脈管または毛細管材などを配置する工程がないため、製造コストを削減し、歩留まりを向上させることができる。 As described above, the present invention produces the effect of generating liquid bullets in the liquid working fluid by dividing the inside of the liquid portion of the reflux tube into small-diameter pipes, so that the liquid working fluid is refluxed in the absence of capillary force. The liquid bullet can be recirculated to the evaporation chamber in the form of advancing by the pressure difference inside the tube.
In the present invention, since there is no step of arranging a mesh-like vessel or capillary material in the liquid portion of the reflux tube, the manufacturing cost can be reduced and the yield can be improved.

以下、本発明による液体弾管路を有する還流ヒートパイプを図面に基づいて説明する。   Hereinafter, a reflux heat pipe having a liquid bullet path according to the present invention will be described with reference to the drawings.

（第１実施形態）
図１から図６に示すように、本発明の第１実施形態による液体弾管路を有する還流ヒートパイプ１０は、蒸発チャンバー１１、還流管２１および作動液３１から構成される。 (First embodiment)
As shown in FIGS. 1 to 6, the reflux heat pipe 10 having the liquid bullet path according to the first embodiment of the present invention includes an evaporation chamber 11, a reflux pipe 21, and a working fluid 31.

蒸発チャンバー１１は、ハウジング１２およびハウジング１２内に配置された毛細管材１４を有する。毛細管材１４はハウジング１２に充満せず、ハウジング１２との間に蒸気空間１６を形成する。
蒸気空間１６は共有室１６１および複数のサイドスペース１６２を有する。複数のサイドスペース１６２は毛細管材１４によって相互に距離を保つ。複数のサイドスペース１６２はそれぞれ共有室１６１に繋がり、それ以外の部位において相互に繋がらない。本実施形態において、毛細管材１４は銅粉末の焼結によって成形される。 The evaporation chamber 11 has a housing 12 and a capillary material 14 disposed in the housing 12. The capillary 14 does not fill the housing 12, and forms a vapor space 16 with the housing 12.
The vapor space 16 has a shared chamber 161 and a plurality of side spaces 162. The plurality of side spaces 162 are kept at a distance from each other by the capillary 14. The plurality of side spaces 162 are each connected to the shared room 161 and are not connected to each other at other portions. In the present embodiment, the capillary material 14 is formed by sintering copper powder.

還流管２１は、一端が気体端２１４となり、別の一端が液体端２１６となる。還流管２１の気体端２１４はハウジング１２に接続され、その空間に繋がる。還流管２１の液体端２１６はハウジング１２に接続され、ハウジング１２の内部に繋がる。   One end of the reflux tube 21 is a gas end 214 and the other end is a liquid end 216. The gas end 214 of the reflux pipe 21 is connected to the housing 12 and connected to the space. The liquid end 216 of the reflux pipe 21 is connected to the housing 12 and is connected to the inside of the housing 12.

作動液３１は、蒸発チャンバー１１に注入される。本実施形態において、作動液は純水からなり、毛細管材１４に吸着し、かつ還流管２１の一部分に存在する。   The working fluid 31 is injected into the evaporation chamber 11. In the present embodiment, the hydraulic fluid is made of pure water, adsorbs on the capillary material 14, and exists in a part of the reflux pipe 21.

還流管２１は長さが所定の部位が冷却部位２２となり、冷却部位２２から気体端２１４までの部分が気体部位２４となり、冷却部位２２から液体端２１６までの部分が液体部位２６となる。放熱部材１００は冷却部位２２の表面に配置され、複数のフィンから構成されてもよい。
還流管２１の液体部位２６は内部に一つのスペーサー２８を有することによって分割され、二つの小管路すなわち液体弾管路２９を形成する。還流管２１の液体部位２６において、二つの液体弾管路２９は相互に繋がらず、それぞれ冷却部位２２およびハウジング１２内部に繋がり、口径が還流管２１の口径より小さい。実際に製作する際、スペーサー２８は還流管２１と一体成型される板体であってもよい。作動液３１は還流管２１の液体部位２６内に位置する。 In the reflux pipe 21, a portion having a predetermined length becomes a cooling portion 22, a portion from the cooling portion 22 to the gas end 214 becomes a gas portion 24, and a portion from the cooling portion 22 to the liquid end 216 becomes a liquid portion 26. The heat dissipating member 100 may be disposed on the surface of the cooling portion 22 and may be composed of a plurality of fins.
The liquid portion 26 of the reflux pipe 21 is divided by having one spacer 28 inside, thereby forming two small pipes, that is, a liquid bullet pipe 29. In the liquid part 26 of the reflux pipe 21, the two liquid bullet paths 29 are not connected to each other, but are connected to the cooling part 22 and the inside of the housing 12, respectively, and the diameter is smaller than the diameter of the reflux pipe 21. When actually manufacturing, the spacer 28 may be a plate integrally molded with the reflux pipe 21. The working fluid 31 is located in the liquid portion 26 of the reflux pipe 21.

本実施形態において、スペーサー２８は液体部位２６に配置されるだけでなく、気体部位２４に届かず冷却部位２２の全体まで延長され、延長距離は冷却部位２２全体の長さまでである。
冷却部位２２は気体作動液が冷却して液体作動液に変化する部位である。スペーサー２８の延長距離が冷却部位２２の長さと一致すれば、液体弾管路２９が冷却部位２２の全体に形成される。液体弾管路２９は還流管２１の口径より小さい管路であり、液体作動液に液体弾３１１を生成させる効果を生じるため、液体作動液は毛管力がない状態で還流管２１内部の圧力差によって液体弾３１１を前進させる形で蒸発チャンバー１１内にスムーズに還流し、毛細管材１４に吸着することができる。 In this embodiment, the spacer 28 is not only disposed in the liquid part 26 but also reaches the entire cooling part 22 without reaching the gas part 24, and the extension distance is up to the entire length of the cooling part 22.
The cooling part 22 is a part where the gas hydraulic fluid cools and changes to a liquid hydraulic fluid. If the extended distance of the spacer 28 matches the length of the cooling part 22, the liquid bullet path 29 is formed in the entire cooling part 22. The liquid bullet line 29 is a pipe line smaller than the diameter of the reflux pipe 21 and produces an effect of generating the liquid bullet 311 in the liquid hydraulic fluid. Therefore, the liquid hydraulic fluid has a pressure difference inside the reflux pipe 21 in a state where there is no capillary force. Thus, the liquid bullet 311 can be smoothly recirculated into the evaporation chamber 11 in the form of advancing, and can be adsorbed on the capillary material 14.

本実施形態において、気体部位２４および液体部位２６は口径が同じである。液体弾管路２９の口径は還流管２１の気体部位２４の口径より小さい。以上により、液体弾管路２９と還流管２１の関係、即ち口径の大きさが判明した。つまり、液体弾管路２９は口径が比較的小さいため、液体弾を生じさせることが容易である。   In the present embodiment, the gas part 24 and the liquid part 26 have the same diameter. The diameter of the liquid bullet channel 29 is smaller than the diameter of the gas portion 24 of the reflux pipe 21. From the above, the relationship between the liquid bullet channel 29 and the reflux tube 21, that is, the size of the aperture was found. That is, since the liquid bullet channel 29 has a relatively small diameter, it is easy to generate a liquid bullet.

図４に示すように、板体のスペーサー２８’は断面形状が直線状に限らず、円弧状であってもよい。図５に示すように、スペーサー２８”の数は一つに限らず、三つでもよい。これによって、還流管２１”は三つの液体弾管路２９”に分割される。図６に示すように、スペーサー２８’’’の形は板状に限らず、柱体に形成された中空管体の管壁であってもよい。   As shown in FIG. 4, the cross-sectional shape of the plate spacer 28 'is not limited to a straight line, but may be an arc. As shown in FIG. 5, the number of spacers 28 "is not limited to one, but may be three. Thereby, the reflux pipe 21" is divided into three liquid bullet paths 29 ". As shown in FIG. In addition, the shape of the spacer 28 '' 'is not limited to a plate shape, and may be a tube wall of a hollow tube formed in a column.

以上は本発明の第１実施形態の構造についての説明である。続いて本発明の第１実施形態の作動状態について説明を進める。   The above is the description of the structure of the first embodiment of the present invention. Subsequently, description will be given on the operating state of the first embodiment of the present invention.

図１および図２に示すように、液体弾管路を有する還流ヒートパイプ１０が作動する前に、コンピューターの中央処理装置（ＣＰＵ）などの発熱源に蒸発チャンバー１１を付着させ、還流管２１の冷却部位２２に放熱部材１００を配置する。本実施形態において、放熱部材１００は複数のフィンから構成される。   As shown in FIG. 1 and FIG. 2, before the reflux heat pipe 10 having a liquid bullet channel is operated, the evaporation chamber 11 is attached to a heat source such as a central processing unit (CPU) of a computer, and the reflux pipe 21 The heat radiating member 100 is disposed in the cooling portion 22. In the present embodiment, the heat dissipation member 100 is composed of a plurality of fins.

液体弾管路を有する還流ヒートパイプ１０を起動すると、発熱源の熱エネルギーは蒸発チャンバー１１に伝導する。続いて蒸発チャンバー１１内の毛細管材１４に吸着した作動液は蒸発し、気体作動液に変わって蒸気空間１６内に拡散する。
蒸気空間１６内の気体作動液は複数のサイドスペース１６２によって十分に拡散し、共有室１６１を通って還流管２１の気体部位２４に流入し、冷却部位２２に到達する。このとき冷却部位２２に位置する放熱部材１００は空気によって熱エネルギーを拡散させ、冷却部位２２の内部温度を蒸発チャンバー１１の温度以下に降下させるため、冷却部位２２内の気体作動液は冷却および凝結し、水滴状の液体作動液に変わって冷却部位２２内の液体弾管路２９の管壁に付着する。
冷却して凝集した液体作動液が多ければ水滴状の液体作動液が大きくなり、液体弾管路２９の断面に充満する液体弾３１１を生成する。続いて、液体弾管路２９は口径が還流管２１より小さいため、液体作動液に液体弾３１１を生成させる効果を有する。気体作動液は気体部位２４から冷却部位２２に持続的に流れ込み、圧力差を生じる。液体弾３１１は気体作動液の生じた圧力差によって冷却部位２２から液体弾管路２９へ前進し、そののち蒸発チャンバー１１に流れ込み、再び毛細管材１４に吸着する。
このような循環作用により発熱源の熱エネルギーを持続的に誘導し、良好な放熱効果を達成することができる。 When the reflux heat pipe 10 having a liquid bullet path is activated, the heat energy of the heat source is conducted to the evaporation chamber 11. Subsequently, the working fluid adsorbed on the capillary material 14 in the evaporation chamber 11 evaporates and diffuses into the vapor space 16 instead of the gas working fluid.
The gas hydraulic fluid in the vapor space 16 is sufficiently diffused by the plurality of side spaces 162, flows into the gas portion 24 of the reflux pipe 21 through the shared chamber 161, and reaches the cooling portion 22. At this time, the heat radiating member 100 located in the cooling part 22 diffuses heat energy by air and lowers the internal temperature of the cooling part 22 to be equal to or lower than the temperature of the evaporation chamber 11, so that the gas hydraulic fluid in the cooling part 22 is cooled and condensed. Then, the liquid hydraulic fluid is changed to a water droplet-like liquid and adheres to the tube wall of the liquid bullet channel 29 in the cooling region 22.
If there are many liquid hydraulic fluids that have cooled and aggregated, the liquid hydraulic fluid in the form of droplets becomes larger, and liquid bullets 311 that fill the cross section of the liquid bullet channel 29 are generated. Subsequently, since the diameter of the liquid bullet channel 29 is smaller than that of the reflux pipe 21, the liquid bullet line 29 has an effect of generating the liquid bullet 311 in the liquid hydraulic fluid. The gas hydraulic fluid continuously flows from the gas part 24 to the cooling part 22 to generate a pressure difference. The liquid bullet 311 advances from the cooling site 22 to the liquid bullet path 29 due to the pressure difference generated by the gas hydraulic fluid, and then flows into the evaporation chamber 11 and is adsorbed on the capillary 14 again.
By such a circulation action, the heat energy of the heat source can be continuously induced, and a good heat radiation effect can be achieved.

上述したとおり、本発明において、還流管２１の液体部位２６は内部が分割されて形成した小口径の液体弾管路２９によって液体作動液に液体弾３１１を生成させる効果を生じるため、液体作動液は毛管力がない状態で還流管２１内部の圧力差によって液体弾３１１を前進させる形で蒸発チャンバー１１内にスムーズに還流することができる。一方、還流管２１の液体部位２６にはメッシュ状脈管または毛細管材などが配置されないため、従来の技術と比べて、本発明は製造コストを削減し、歩留まりを向上させることができる。   As described above, in the present invention, the liquid portion 26 of the reflux pipe 21 has an effect of generating the liquid bullet 311 in the liquid hydraulic fluid by the small-diameter liquid bullet passage 29 formed by dividing the inside thereof. Can smoothly recirculate into the evaporation chamber 11 by advancing the liquid bullet 311 by the pressure difference inside the reflux tube 21 in the absence of capillary force. On the other hand, since the mesh-like vascular or capillary material is not disposed in the liquid portion 26 of the reflux tube 21, the present invention can reduce the manufacturing cost and improve the yield compared with the conventional technique.

（第２実施形態）
図７は本発明の第２実施形態による液体弾管路を有する還流ヒートパイプ４０を示す横断面図である。第１実施形態との違いは次のとおりである。 (Second Embodiment)
FIG. 7 is a cross-sectional view showing a reflux heat pipe 40 having a liquid bullet path according to the second embodiment of the present invention. Differences from the first embodiment are as follows.

第２実施形態において、毛細管材４４はハウジング４２との間に形成された貯水空間４７を有する。貯水空間４７は蒸気空間４６に繋がらず、還流管の液体端に繋がる。管貯水空間４７は作動液の調節に用いられ、かつ従来の還流ヒートパイプに液体作動液を還流させる液体部位が必要であるために設計される。
蒸発チャンバー内の作動液の大部分が還流管の気体部位、冷却部位および液体部位に留まり、蒸発チャンバーに還流してこない場合、蒸発チャンバーは内部の水量が少な過ぎるため効果的に作動できない状態、即ち空焼きを発生させる。それに対し、貯水空間４７は作動液の水量を調節する効果を有するため、蒸発チャンバー１１内の作動液４９の量を一定にし、空焼きを防止することができる。 In the second embodiment, the capillary material 44 has a water storage space 47 formed between it and the housing 42. The water storage space 47 is not connected to the vapor space 46 but is connected to the liquid end of the reflux pipe. The pipe water storage space 47 is used for adjusting the working fluid, and is designed because the conventional reflux heat pipe needs a liquid portion for refluxing the liquid working fluid.
If most of the working fluid in the evaporation chamber stays in the gas part, cooling part and liquid part of the reflux pipe and does not return to the evaporation chamber, the evaporation chamber is in an inoperable state due to too little water inside, That is, empty baking is generated. On the other hand, since the water storage space 47 has an effect of adjusting the amount of the hydraulic fluid, the amount of the hydraulic fluid 49 in the evaporation chamber 11 can be made constant to prevent empty baking.

第２実施形態において、スペーサー５８は冷却部位５２まで延長されないため、冷却部位５２内の液体作動液は直接液体弾管路５９に流入できなくても、ある程度の量が貯まると液体弾管路５９に流入できる。第２実施形態は液体弾を生成する効果が第１実施形態ほどではないが、液体部位５６の液体弾管路５９によって液体作動液に液体弾を生成させる効果を発揮できるため、液体作動液は蒸発チャンバー４１に容易に還流できる。   In the second embodiment, since the spacer 58 is not extended to the cooling portion 52, even if the liquid hydraulic fluid in the cooling portion 52 cannot directly flow into the liquid bullet passage 59, if a certain amount is accumulated, the liquid bullet passage 59 is accumulated. Can flow into. In the second embodiment, the effect of generating a liquid bullet is not as great as that of the first embodiment, but since the liquid bullet can be generated in the liquid hydraulic fluid by the liquid bullet channel 59 of the liquid portion 56, the liquid hydraulic fluid is It can be easily refluxed to the evaporation chamber 41.

第２実施形態に対し、スペーサー５８を液体部位５６から冷却部位５２の長さの半分まで伸ばせば液体弾管路５９が冷却部位５２の長さの半分まで伸びる。このような構造によって液体弾を生成する効果は第１実施形態ほどではないが、第２実施形態に優れる。   In contrast to the second embodiment, when the spacer 58 is extended from the liquid portion 56 to half the length of the cooling portion 52, the liquid bullet path 59 extends to half the length of the cooling portion 52. The effect of generating liquid bullets by such a structure is not as good as that of the first embodiment, but is superior to the second embodiment.

第２実施形態のほかの構造および達成できる効果は第１実施形態と同じであるため、説明を省略する。   Since the other structures and effects that can be achieved in the second embodiment are the same as those in the first embodiment, description thereof is omitted.

（第３実施形態）
図８は本発明の第３実施形態による液体弾管路を有する還流ヒートパイプ６０を示す横断面図である。第１実施形態との違いは次のとおりである。 (Third embodiment)
FIG. 8 is a cross-sectional view showing a reflux heat pipe 60 having a liquid bullet path according to a third embodiment of the present invention. Differences from the first embodiment are as follows.

第３実施形態において、スペーサー６８は冷却部位６２および気体部位６４の気体端６１４まで伸びるように配置される。   In the third embodiment, the spacer 68 is arranged to extend to the cooling end 62 and the gas end 614 of the gas portion 64.

上述した構造により、気体作動液は気体部位６４から直接小口径の液体弾管路６９に流入し、冷却部位６２に到達する前に小さい水滴を凝集させる。凝集した小さい水滴は少量であるため、液体弾にならない。言い換えれば、上述した構造は全体の作動効率に影響を与えることがなく、液体弾管路６９が還流管６１の内部全体に形成されるため、直接丸々一本のパイプを組み合わせるのみでできる。
つまり、還流管６１の一部分にスペーサーを配置しない別の製造工程も、第１実施形態のようにスペーサー６８を冷却部位６２まで正確に延長する製造工程も必要ではない。従って、第３実施形態は第１実施形態より製造コストを削減できる。 With the above-described structure, the gas hydraulic fluid flows directly from the gas portion 64 into the small diameter liquid bullet channel 69 and aggregates small water droplets before reaching the cooling portion 62. Since the small water droplets that have aggregated are small, they do not become liquid bullets. In other words, the above-described structure does not affect the overall operation efficiency, and the liquid bullet channel 69 is formed in the entire interior of the reflux pipe 61, so that it is possible to directly combine a single pipe.
That is, another manufacturing process in which the spacer is not disposed in a part of the reflux pipe 61 and a manufacturing process for accurately extending the spacer 68 to the cooling portion 62 as in the first embodiment are not required. Therefore, the third embodiment can reduce the manufacturing cost compared to the first embodiment.

第３実施形態のほかの構造および達成できる効果は第１実施形態と同じであるため、説明を省略する。   Since the other structures and effects that can be achieved in the third embodiment are the same as those in the first embodiment, description thereof is omitted.

（第４実施形態）
図９は本発明の第４実施形態による液体弾管路を有する還流ヒートパイプ７０を示す横断面図である。第１実施形態との違いは次のとおりである。 (Fourth embodiment)
FIG. 9 is a cross-sectional view showing a reflux heat pipe 70 having a liquid bullet path according to a fourth embodiment of the present invention. Differences from the first embodiment are as follows.

第４実施形態において、還流管７１は二つの管体７１ａ、７１ｂを有する。液体部位７６および冷却部位７２は管体７１ｂから形成される。気体部位７４は管体７１ａから形成される。気体部位７４の口径は液体部位７６および冷却部位７２の口径より小さい。液体部位７６および冷却部位７２になる管体７１ｂは気体部位７４になる管体７１ａの外部の一部分に嵌まり、管体７１ｂ、管体７１ａの内部空間を相互に連絡させる。
上述した構造により、二つの管体７１ａ、７１ｂを連結して還流管７１を形成する連結関係が明確化した。気体部位７４になる管体７１ａの内部にはスペーサーを配置せず、液体部位７６および冷却部位７２になる管体７１ｂの内部にスペーサーを配置すればよい。 In the fourth embodiment, the reflux pipe 71 has two pipe bodies 71a and 71b. The liquid part 76 and the cooling part 72 are formed from the pipe body 71b. The gas portion 74 is formed from the tube body 71a. The diameter of the gas part 74 is smaller than the diameters of the liquid part 76 and the cooling part 72. The pipe body 71b that becomes the liquid part 76 and the cooling part 72 fits in a part of the outside of the pipe body 71a that becomes the gas part 74, and connects the pipe body 71b and the internal space of the pipe body 71a to each other.
With the structure described above, the connection relationship in which the two pipe bodies 71a and 71b are connected to form the reflux pipe 71 is clarified. A spacer may be disposed inside the tube 71 b that becomes the liquid portion 76 and the cooling portion 72 without arranging the spacer inside the tube 71 a that becomes the gas portion 74.

つまり、第４実施形態の構築は二つの異なる管体を連結して還流管７１を形成することが特徴である。   That is, the construction of the fourth embodiment is characterized in that the reflux pipe 71 is formed by connecting two different pipe bodies.

第４実施形態のほかの構造および達成できる効果は第１実施形態と同じであるため、説明を省略する。   Since the other structures and effects that can be achieved in the fourth embodiment are the same as those in the first embodiment, description thereof is omitted.

（第５実施形態）
図１０は本発明の第５実施形態による液体弾管路を有する還流ヒートパイプ８０を示す横断面図である。第４実施形態との違いは次のとおりである。 (Fifth embodiment)
FIG. 10 is a cross-sectional view showing a reflux heat pipe 80 having a liquid bullet path according to a fifth embodiment of the present invention. Differences from the fourth embodiment are as follows.

第５実施形態において、還流管８１は二つの管体８１ａ、８１ｂを有する。液体部位８６および冷却部位８２は管体８１ｂから形成される。気体部位８４は管体８１ａから形成される。
気体部位８４になる管体８１ａは管体８１ｂの外部の一部分に嵌り、管体８１ａと管体８１ｂの内部空間とを相互に連絡させる。気体部位８４になる管体８１ａの口径が管体８１ｂの口径より小さいため、製造する際には、気体部位８４になる管体８１ａの末端部を拡張し、口径を大きくした後、管体８１ｂに管体８１ａを嵌める。 In the fifth embodiment, the reflux pipe 81 has two pipe bodies 81a and 81b. The liquid part 86 and the cooling part 82 are formed from the tubular body 81b. The gas part 84 is formed from the tubular body 81a.
The tubular body 81a that becomes the gas portion 84 is fitted to a part of the exterior of the tubular body 81b, and connects the tubular body 81a and the internal space of the tubular body 81b to each other. Since the diameter of the tube 81a that becomes the gas portion 84 is smaller than the diameter of the tube 81b, when manufacturing, the end portion of the tube 81a that becomes the gas portion 84 is expanded to increase the diameter, and then the tube 81b. The tubular body 81a is fitted into.

第５実施形態の構築は上述に限らず、気体部位８４になる管体８１ａの口径が管体８１ｂより小さくても、小口径の管体で大口径の管体を連結してもよい。   The construction of the fifth embodiment is not limited to the above, and the pipe body 81a serving as the gas portion 84 may be smaller in diameter than the pipe body 81b, or a large-diameter pipe body may be connected with a small-diameter pipe body.

第５実施形態のほかの構造および達成できる効果は第４実施形態と同じであるため、説明を省略する。   Since the other structures and effects that can be achieved in the fifth embodiment are the same as those in the fourth embodiment, description thereof is omitted.
