上述した課題を解決するための、口径の異なる還流ヒートパイプは蒸発チャンバー、冷却部材、気流管部および液流管部を備える。
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発空間を形成する。冷却部材は外部に放熱部材を有し、内部に流体流路を有する。流体流路は一端が気体接続端部になり、別の一端が液体接続端部になる。気体接続端部の内径は液体接続端部の内径より大きい。気流管部は一端がハウジングに連結されて蒸発空間に繋がり、別の一端が冷却部材の気体接続端部に連結されて流体流路に繋がる。液流管部は一端がハウジングに連結されてハウジングの内部に繋がり、別の一端が冷却部材の液体接続端部に連結されて流体流路に繋がる。液流管部の内径は気流管部の内径より小さい。 In order to solve the above-described problems, a reflux heat pipe having a different diameter includes an evaporation chamber, a cooling member, an airflow pipe section, and a liquid flow pipe section.
The evaporation chamber has a housing and a capillary material disposed within the housing. The capillary material does not fill the housing, and forms an evaporation space with the housing. The cooling member has a heat radiating member on the outside and a fluid flow path on the inside. One end of the fluid channel is a gas connection end, and the other end is a liquid connection end. The inner diameter of the gas connection end is larger than the inner diameter of the liquid connection end. One end of the airflow tube portion is connected to the housing and connected to the evaporation space, and the other end is connected to the gas connection end portion of the cooling member and connected to the fluid flow path. One end of the liquid flow pipe portion is connected to the housing and connected to the inside of the housing, and the other end is connected to the liquid connection end portion of the cooling member and connected to the fluid flow path. The inner diameter of the liquid flow tube portion is smaller than the inner diameter of the air flow tube portion.

上述したとおり、本発明は液流管部の口径が気流管部の口径より小さいことで液体弾を生成する効果を生じるため、液体作動液は毛管力がない状態で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に順調に還流し、放熱効率を向上させることができる。   As described above, the present invention produces an effect of generating liquid bullets because the diameter of the liquid flow pipe part is smaller than the diameter of the airflow pipe part, so that the liquid hydraulic fluid advances the liquid bullets by pressure difference in the absence of capillary force.

作動液５１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５１は純水からなり、毛細管材１３に吸着し、かつ還流ヒートパイプ１０の一部分に存在する。   The working fluid 51 is injected into the evaporation chamber 11. In the present embodiment, the hydraulic fluid 51 is made of pure water, adsorbs on the capillary material 13, and exists in a part of the reflux heat pipe 10.

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.

還流ヒートパイプが作動する際、電子装置などの発熱源（図中未表示）は蒸発チャンバー１１の上に配置され、暫く稼働した後、熱エネルギーを生じ、熱伝導方式によって蒸発チャンバー１１に伝導させ、同時に毛細管材１３へ拡散させる。作動液５１の大部分は液体状態で毛細管材１３内に保存される。熱エネルギーが毛細管材１３に伝導する際、毛細管材１３は昇温し、毛細管材１３内の液体作動液に熱エネルギーを十分に吸収させ、蒸発反応を起こして気体作動液を生成する。
気体作動液は毛細管材１３の複数の流路１３１の開口部１３２から蒸発空間１２５に流入し、集結した後、気流管部３１を流動し、冷却部材２１の方向に前進し、気体接続端部２１２から冷却部材２１に流入する。冷却部材２１の外部の放熱部材１００は冷却部材２１を流動する気体作動液の熱エネルギーを空気中に拡散させるため、気体作動液は冷却し、水滴状の液体作動液を凝結させて冷却部材２１の管壁に付着させる。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る。冷却部材２１の液体接続端部２１３の孔径が比較的小さいため、水滴状の液体作動液は迅速に液体接続端部２１３に充満して液流管部４１に流入し、液流管部４１の断面に充満する液体弾５１１を生成する。続いて、液流管部４１の口径が比較的小さいため、液体弾５１１は毛管力がない状態で気流管部３１および液流管部４１内の圧力差によって前進し、かつ液流管部４１を容易かつ迅速に流動することができる。
一方、気体作動液は気流管部３１から冷却部材２１に持続的に流れ込んで液体弾５１１を前進させる力を生じ、続いて蒸発チャンバー１１に還流し、再び毛細管材１３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 operates, a heat source such as an electronic device (not shown in the figure) is disposed on the evaporation chamber 11 and after operating for a while, generates heat energy and conducts it to the evaporation chamber 11 by a heat conduction method. At the same time, it is diffused into the capillary material 13. Most of the working fluid 51 is stored in the capillary 13 in a liquid state. When the thermal energy is conducted to the capillary material 13, the capillary material 13 is heated, and the liquid hydraulic fluid in the capillary material 13 sufficiently absorbs the thermal energy to cause an evaporation reaction to generate a gas hydraulic fluid.
After the gas hydraulic fluid flows into the evaporation space 125 from the openings 132 of the plurality of flow paths 131 of the capillary material 13 and is collected, the gas hydraulic fluid flows through the airflow tube portion 31 and advances in the direction of the cooling member 21, and the gas connection end portion It flows from 212 to the cooling member 21. The heat dissipating member 100 outside the cooling member 21 diffuses the thermal energy of the gas working fluid flowing through the cooling member 21 into the air. Therefore, the gas working fluid is cooled and the water droplet-like liquid working fluid is condensed to form the cooling member 21. Adhere to the tube wall. If there are many liquid working fluids that have cooled and aggregated, the liquid working fluid in the form of droplets becomes larger. Since the hole diameter of the liquid connection end portion 213 of the cooling member 21 is relatively small, the water droplet-like liquid working fluid quickly fills the liquid connection end portion 213 and flows into the liquid flow tube portion 41. A liquid bullet 511 that fills the cross section is generated. Subsequently, since the diameter of the liquid flow tube portion 41 is relatively small, the liquid bullet 511 moves forward due to a pressure difference between the air flow tube portion 31 and the liquid flow tube portion 41 in the absence of capillary force, and the liquid flow tube portion 41. Can flow easily and quickly.
On the other hand, the gas hydraulic fluid continuously flows into the cooling member 21 from the air flow tube portion 31 to generate a force for moving the liquid bullet 511 forward, then returns to the evaporation chamber 11 and is adsorbed on the capillary material 13 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、本発明は液流管部４１の口径が気流管部３１より小さく、気流管部３１および液流管部４１を連結する冷却部材２１の液体接続端部２１３の孔径が気体接続端部２１２より小さいため、図３に示すように、断面積の小さい液流管部４１の中に液体弾５１１を生成できるだけでなく、毛管力がない状態で気流管部３１および液流管部４１内の圧力差によって液体弾５１１を前進させる方式で液体作動液を蒸発チャンバー１１に順調かつ迅速に還流させることができる。   As described above, in the present invention, the diameter of the liquid flow pipe part 41 is smaller than that of the air flow pipe part 31, and the hole diameter of the liquid connection end part 213 of the cooling member 21 connecting the air flow pipe part 31 and the liquid flow pipe part 41 is the gas connection end. Since it is smaller than the portion 212, as shown in FIG. 3, not only can the liquid bullet 511 be generated in the liquid flow tube portion 41 having a small cross-sectional area, but also the air flow tube portion 31 and the liquid flow tube portion 41 in the absence of capillary force. The liquid hydraulic fluid can be smoothly and quickly refluxed to the evaporation chamber 11 by a method in which the liquid bullet 511 is advanced by the pressure difference inside.

（第２実施形態）
図４および図５は本発明の第２実施形態による還流ヒートパイプ１０’を示す斜視図および横断面図である。第１実施形態との違いは次のとおりである。 (Second Embodiment)
4 and 5 are a perspective view and a cross-sectional view showing a reflux heat pipe 10 'according to a second embodiment of the present invention. Differences from the first embodiment are as follows.

第２実施形態において、第一孔１２３’および蒸発空間１２５’は格納ケース１２２’の同じ側に位置する。第一孔１２３’および第二孔１２４’は格納ケース１２２’の異なる側に位置する。第一孔１２３’は蒸発空間１２５’に繋がり、孔径が第二孔１２４’より大きい。気流管部３１’は一端が格納ケース１２２’の第一孔１２３’に差し込まれることによってハウジング１２’に連結される。
液流管部４１’は一端が格納ケース１２２’の第二孔１２４’に差し込まれることによってハウジング１２’に連結される。冷却部材２１’は中空パイプからなる。流体流路２１１’は中空パイプの内部に位置し、中空パイプの両端を別々に貫通する気体接続端部２１２’および液体接続端部２１３’を有する。気体接続端部２１２’の内径は液体接続端部２１３’の内径より大きい。放熱部材１００’は中空パイプの周りに配列する複数のフィンから構成される。 In the second embodiment, the first hole 123 ′ and the evaporation space 125 ′ are located on the same side of the storage case 122 ′. The first hole 123 ′ and the second hole 124 ′ are located on different sides of the storage case 122 ′. The first hole 123 ′ is connected to the evaporation space 125 ′ and has a larger diameter than the second hole 124 ′. One end of the airflow pipe portion 31 ′ is connected to the housing 12 ′ by being inserted into the first hole 123 ′ of the storage case 122 ′.
One end of the liquid flow pipe portion 41 ′ is connected to the housing 12 ′ by being inserted into the second hole 124 ′ of the storage case 122 ′. The cooling member 21 ′ is made of a hollow pipe. The fluid flow path 211 ′ is located inside the hollow pipe and has a gas connection end 212 ′ and a liquid connection end 213 ′ penetrating both ends of the hollow pipe separately. The inner diameter of the gas connection end 212 ′ is larger than the inner diameter of the liquid connection end 213 ′. The heat dissipating member 100 ′ is composed of a plurality of fins arranged around the hollow pipe.

第１実施形態と同様に、液流管部４１’は口径が気流管部３１’より小さいため、図５に示すように、液体作動液は液体弾５１１’を生成し、毛管力がない状態で気流管部３１’および液流管部４１’内の圧力差によって液体弾５１１’を前進させ、液流管部４１’内の液体弾５１１’を順調に流動させることができる。従って、第２実施形態は第１実施形態と同様に液体作動液を蒸発チャンバー１１’に順調かつ迅速に還流させる効果を有する。   As in the first embodiment, since the liquid flow tube portion 41 ′ has a smaller diameter than the air flow tube portion 31 ′, the liquid hydraulic fluid generates a liquid bullet 511 ′ and has no capillary force, as shown in FIG. Thus, the liquid bullet 511 ′ can be moved forward by the pressure difference in the airflow pipe section 31 ′ and the liquid flow pipe section 41 ′, and the liquid bullet 511 ′ in the liquid flow pipe section 41 ′ can be smoothly flowed. Therefore, the second embodiment has the effect of smoothly and rapidly refluxing the liquid working fluid to the evaporation chamber 11 ′ as in the first embodiment.

第２実施形態のほかのステップ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 steps and effects that can be achieved in the second embodiment are the same as those in the first embodiment, description thereof is omitted.
