Description

本発明は、放熱装置に関し、詳しくは同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプに関するものである。   The present invention relates to a heat radiating device, and more particularly to a reflux heat pipe in which the same pipe is divided into an air flow channel and a liquid flow channel.

特許文献１により掲示された還流ヒートパイプにおいて、中空パイプは折り曲げられ、二つの管路に分割され、一つの管路が蒸発部位となり、別の一つの管路が冷却部位となる。二つの管路の開口部は密封キャップに嵌合され、相対する側の管壁が平坦な壁面に形成され、相互に密着する。密封キャップは密封端部および嵌合端部を有する。嵌合端部はスリーブの形である。二つの管路を組み合わせる際、密封キャップはスリーブの形で二つの管路を連結することができる。
特許文献２により掲示された還流ヒートパイプにおいて、中空パイプは二つの管路を有し、一つの管路が蒸発部位となり、別の一つの管路が冷却部位となる。密封キャップは密封端部および嵌合端部を有する。嵌合端部はスリーブの形である。二つの管路を組み合わせる際、スリーブの形の嵌合端部と二つの管路の開口部との間の隙間を充填剤で埋める。
特許文献１および特許文献２において、蒸発部位となる管路および冷却部位となる管路は同じ大直径の管体であるが、冷却した液体を容易に流動させるように設計されなかったため、液体状態で流動する作動液は蒸発チャンバーに還流することが順調でなく、循環速度が遅く、放熱効率に影響を与える。一方、密封キャップと管体は組み合わせにくいため、管体の形を変えるか、再び隙間に填充剤を充填することが必要であれば、製造コストが増加する。 In the reflux heat pipe posted by patent document 1, a hollow pipe is bent and divided | segmented into two pipe lines, one pipe line becomes an evaporation part, and another one pipe line becomes a cooling part. The openings of the two pipe lines are fitted into a sealing cap, and the opposite pipe wall is formed on a flat wall surface so as to be in close contact with each other. The sealing cap has a sealing end and a mating end. The mating end is in the form of a sleeve. When combining two lines, the sealing cap can connect the two lines in the form of a sleeve.
In the reflux heat pipe posted by patent document 2, a hollow pipe has two pipe lines, one pipe line becomes an evaporation site | part, and another one pipe line becomes a cooling site | part. The sealing cap has a sealing end and a mating end. The mating end is in the form of a sleeve. When combining the two lines, the gap between the mating end in the form of a sleeve and the opening of the two lines is filled with a filler.
In Patent Document 1 and Patent Document 2, the pipeline serving as the evaporation site and the pipeline serving as the cooling site are the same large-diameter tube, but the liquid state is not designed to easily flow the cooled liquid. The working fluid that flows in the flow is not smoothly returned to the evaporation chamber, the circulation speed is slow, and the heat dissipation efficiency is affected. On the other hand, since it is difficult to combine the sealing cap and the tube, the manufacturing cost increases if it is necessary to change the shape of the tube or to refill the gap with a filler.

本発明は、同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプを提供することを主な目的とする。
同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプは少なくとも一つのスペーサーで還流管を仕切って構成した少なくとも一つの気流流路および液流流路と、連結キャップとを組み合わせて流動部位を形成し、同じ還流管内に位置する少なくとも一つの気流流路および液流通路を繋げることによって液体作動液に液体弾を生成させ、圧力差によって液体弾を前進させるため、液体作動液を蒸発チャンバーまで順調に還流させ、放熱効率を向上させることができる。 The main object of the present invention is to provide a reflux heat pipe in which the same pipe line is partitioned into an air flow channel and a liquid flow channel.
A reflux heat pipe in which the same pipe is divided into an air flow channel and a liquid flow channel is a combination of at least one air flow channel and liquid flow channel configured by partitioning the reflux pipe with at least one spacer and a connection cap. The liquid hydraulic fluid is formed to form a liquid bullet in the liquid hydraulic fluid by connecting at least one air flow channel and a liquid flow channel located in the same reflux pipe and to advance the liquid bullet by the pressure difference. Can be circulated smoothly to the evaporation chamber to improve the heat dissipation efficiency.

上述した課題を解決するため、同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプは蒸発チャンバー、還流管、放熱部材および連結キャップを備える。
蒸発チャンバーはハウジング、ハウジング内に配置された毛細管材およびハウジング内に注入された作動液を有する。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。還流管は一端が接続端となり、別の一端が嵌合端となる。還流管の接続端はハウジングに接続されて還流管とハウジング内の空間を繋げる。還流管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流路に分割される。二つ以上の流路は還流管内に相互に連絡しない少なくとも一つの気流流路および液流流路と定義される。放熱部材は還流管の嵌合端に隣接するように還流管の外部に配置される。連結キャップは還流管の嵌合端に被さり、還流管内の少なくとも一つのスペーサーに間隔を置いて流動部位を形成し、流動部位によって還流管内の少なくとも一つの気流流路および液流流路を繋げる。 In order to solve the above-described problem, a reflux heat pipe in which the same pipe line is partitioned into an air flow path and a liquid flow path includes an evaporation chamber, a reflux pipe, a heat radiating member, and a connection cap.
The evaporation chamber has a housing, a capillary material disposed in the housing, and a working fluid injected into the housing. The capillary material does not fill the housing, and forms a vapor space with the housing. One end of the reflux pipe is a connection end, and the other end is a fitting end. The connection end of the reflux pipe is connected to the housing to connect the reflux pipe and the space in the housing. The reflux tube is divided into two or more flow paths by at least one spacer inside. Two or more flow paths are defined as at least one air flow path and liquid flow path that do not communicate with each other in the reflux pipe. The heat dissipating member is disposed outside the reflux pipe so as to be adjacent to the fitting end of the reflux pipe. The coupling cap covers the fitting end of the reflux pipe, forms a flow site with an interval between at least one spacer in the reflux pipe, and connects at least one air flow channel and liquid flow channel in the reflux pipe by the flow site.

上述したとおり、本発明は少なくとも一つのスペーサーで還流管を仕切って構成した少なくとも一つの気流流路および液流流路によって液体作動液に液体弾を生成させ、圧力差によって液体弾を前進させるため、液体作動液を蒸発チャンバーまで順調に還流させ、放熱効率を向上させることができる。   As described above, the present invention generates liquid bullets in the liquid working fluid by at least one air flow channel and liquid flow channel configured by partitioning the reflux pipe with at least one spacer, and advances the liquid bullets by the pressure difference. The liquid working fluid can be circulated smoothly to the evaporation chamber, and the heat radiation efficiency can be improved.

以下、本発明による同じ管路が気流流路および液流流路に仕切られた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 in which the same pipe line according to the present invention is partitioned into an air flow channel and a liquid flow channel will be described with reference to the drawings.

（第１実施形態）
本発明の第１実施形態において、同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプ１０は蒸発チャンバー１１、還流管１５、連結キャップ１９および放熱部材１００から構成される。本明細書は二つの還流管を配置する例について説明を進める。 (First embodiment)
In the first embodiment of the present invention, the reflux heat pipe 10 in which the same pipe line is partitioned into an air flow channel and a liquid flow channel includes an evaporation chamber 11, a reflux pipe 15, a connecting cap 19, and a heat dissipation member 100. The present specification proceeds with an example in which two reflux pipes are arranged.

図１から図５に示したのは第１実施形態による同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプ１０である。   1 to 5 show a reflux heat pipe 10 in which the same pipe line according to the first embodiment is partitioned into an air flow channel and a liquid flow channel.

蒸発チャンバー１１は、ハウジング１１１、ハウジング１１１内に配置された毛細管材１２およびハウジング１１１内に注入された作動液１３を有する。毛細管材１２はハウジング１１１に充満せず、ハウジング１１１との間に蒸気空間１４を形成する。
ハウジング１１１は蓋１１１１および格納ケース１１１２からなる。毛細管材１２は格納ケース１１１２内に格納される。蓋１１１１は格納ケース１１１２に被さる。格納ケース１１１２は周りに形成された四つの側壁と、側壁に形成された穿孔１１１３とを有する。穿孔１１１３および蒸発空間１４は相互に繋がるように同じ側に位置する。還流管１５は格納ケース１１１２の穿孔１１１３に差し込まれる。 The evaporation chamber 11 includes a housing 111, a capillary material 12 disposed in the housing 111, and a working fluid 13 injected into the housing 111. The capillary material 12 does not fill the housing 111, and forms a vapor space 14 with the housing 111.
The housing 111 includes a lid 1111 and a storage case 1112. The capillary material 12 is stored in the storage case 1112. The lid 1111 covers the storage case 1112. The storage case 1112 has four side walls formed around it and perforations 1113 formed in the side walls. The perforations 1113 and the evaporation space 14 are located on the same side so as to be connected to each other. The reflux pipe 15 is inserted into the perforation 1113 of the storage case 1112.

本実施形態において、毛細管材１２は銅粉末の焼結によって成形され、複数の流路１２１を有する。複数の流路１２１の開口部１２２は蒸発空間１４に繋がる。毛細管材はさらに複数の流路１２１の開口部１２２と同じ側から外側の所定距離まで伸びていく延長部１２３を有する。   In the present embodiment, the capillary material 12 is formed by sintering copper powder and has a plurality of flow paths 121. The openings 122 of the plurality of flow paths 121 are connected to the evaporation space 14. The capillary material further has an extension 123 that extends from the same side as the opening 122 of the plurality of channels 121 to a predetermined distance outside.

本実施形態において、作動液１３は純水からなり、蒸発チャンバー１１に注入され、毛細管材１２に吸着し、かつ還流管１５の一部分に存在する。   In the present embodiment, the working fluid 13 is made of pure water, injected into the evaporation chamber 11, adsorbed on the capillary tube 12, and exists in a part of the reflux pipe 15.

還流管１５は、一端が接続端１５１となり、別の一端が嵌合端１５２となる。接続端１５１はハウジング１１１の穿孔１１１３に差し込まれてハウジング１１１内の空間に繋がる。還流管１５は内部にスペーサー１６を有する。本実施形態において、スペーサー１６は板状を呈し、還流管１５を気流流路１７および液流流路１８に仕切る。気流流路１７および液流流路１８は還流管１５内に相互に連絡しない。スペーサー１６を製作する際、スペーサー１６および還流管１５は一体成型されてもよい。
毛細管材１２の延長部１２３は還流管１５の液流流路１８の形に対応するように配置される。本実施形態において、還流管１５の液流流路１８は半円形を呈する。毛細管材１２の延長部１２３は還流管１５の液流流路１８内の所定長さまで入り込んで蒸発チャンバー１４と液流流路１８の間の流路を遮断し、図５に示すように気体作動液が液流流路１８へ流入することを抑制することが目的である。延長部１２３は上述に限定されず、本発明に必須な部材でないため、配置されなくてもよい。 One end of the reflux pipe 15 serves as a connection end 151, and the other end serves as a fitting end 152. The connection end 151 is inserted into the perforation 1113 of the housing 111 and connected to the space in the housing 111. The reflux tube 15 has a spacer 16 inside. In the present embodiment, the spacer 16 has a plate shape and partitions the reflux pipe 15 into an air flow channel 17 and a liquid flow channel 18. The air flow channel 17 and the liquid flow channel 18 do not communicate with each other in the reflux pipe 15. When the spacer 16 is manufactured, the spacer 16 and the reflux pipe 15 may be integrally formed.
The extension 123 of the capillary material 12 is arranged so as to correspond to the shape of the liquid flow channel 18 of the reflux pipe 15. In the present embodiment, the liquid flow channel 18 of the reflux pipe 15 has a semicircular shape. The extension part 123 of the capillary material 12 enters a predetermined length in the liquid flow path 18 of the reflux pipe 15 to block the flow path between the evaporation chamber 14 and the liquid flow path 18, and the gas operation is performed as shown in FIG. 5. The purpose is to prevent the liquid from flowing into the liquid flow channel 18. The extension part 123 is not limited to the above, and is not an essential member of the present invention, and may not be arranged.

連結キャップ１９は、内側に凹状部１９１を有する。凹状部１９１は階段状の穴を呈し、開口端部１９１１、末端部１９１２および環状ストッパー１９１３を有する。開口端部１９１１の内径は末端部１９１２の内径より大きい。環状ストッパー１９１３は開口端部１９１１と末端部１９１２との間に形成される。
還流管１５の嵌合端１５２が凹状部１９１の開口端部１９１１に差し込まれる際、還流管１５の嵌合端１５２は連結キャップ１９の凹状部１９１の末端部１９１２に接触せず、環状ストッパー１９１３に当接して固定されるため、還流管１５の嵌合端１５２と連結キャップ１９の凹状部１９１の末端部１９１２との間には流動部位１９２が形成される。連結キャップ１９が還流管１５の嵌合端１５２に被さる際、還流管１５内の気流流路１７および液流流路１８は流動部位１９２によって繋がる。 The connection cap 19 has a concave portion 191 on the inner side. The concave portion 191 has a stepped hole and has an open end 1911, a terminal end 1912, and an annular stopper 1913. The inner diameter of the open end 1911 is larger than the inner diameter of the end 1912. An annular stopper 1913 is formed between the open end 1911 and the end 1912.
When the fitting end 152 of the reflux pipe 15 is inserted into the opening end 1911 of the concave portion 191, the fitting end 152 of the reflux pipe 15 does not contact the end portion 1912 of the concave portion 191 of the connection cap 19, and the annular stopper 1913. Therefore, a flow portion 192 is formed between the fitting end 152 of the reflux pipe 15 and the end portion 1912 of the concave portion 191 of the connection cap 19. When the coupling cap 19 covers the fitting end 152 of the reflux pipe 15, the air flow channel 17 and the liquid flow channel 18 in the reflux pipe 15 are connected by the flow portion 192.

放熱部材１００は、還流管１５の嵌合端１５２に隣接するように還流管１５の外部に配置される。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。   The heat radiating member 100 is disposed outside the reflux pipe 15 so as to be adjacent to the fitting end 152 of the reflux pipe 15. In the present embodiment, the heat dissipation member 100 is composed of a plurality of fins.

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１０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１２へ拡散させる。作動液１３の大部分は液体状態で毛細管材１２内に保存される。熱エネルギーが毛細管材１２に伝導する際、毛細管材１２は昇温し、毛細管材１２内の液体作動液１３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１３を生成する。
気体作動液１３は毛細管材１２の複数の流路１２１の開口部１２２から蒸発空間１４に流入し、集結した後、還流管１５の気流流路１７を流動し、連結キャップ１９の方向に前進し、連結キャップ１９に流入する。続いて還流管１５の嵌合端１５２に隣接するように還流管１５の外部に配置される放熱部材１００は気体作動液１３の熱エネルギーを吸収し、同時に空気中に拡散させる。このとき気体作動液１３は放熱部材１００の冷却作用によって水滴状の液体作動液１３を凝結させる。図４に示すように、凝集した水滴状の液体作動液１３が多くなると液体弾１３１を生成する。圧力差によって液体弾１３１を前進させれば、液体作動液１３は蒸発チャンバー１１に還流し易くなり、かつ蒸発チャンバー１１まで順調に還流して放熱効率を向上させることができる。このような循環作用により電子装置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 is operated, a heat source (not shown in the figure) such as an electronic device is disposed on the evaporation chamber 11, and after operating for a while, generates heat energy and is conducted to the evaporation chamber 11 by a heat conduction method. And simultaneously diffuse into the capillary material 12. Most of the working fluid 13 is stored in the capillary 12 in a liquid state. When the thermal energy is conducted to the capillary material 12, the capillary material 12 is heated, and the liquid working liquid 13 in the capillary material 12 sufficiently absorbs the thermal energy to cause an evaporation reaction to generate the gas working liquid 13.
The gas working liquid 13 flows into the evaporation space 14 from the openings 122 of the plurality of flow paths 121 of the capillary material 12 and is collected, and then flows in the air flow path 17 of the reflux pipe 15 and advances toward the connection cap 19. , Flows into the connecting cap 19. Subsequently, the heat radiating member 100 disposed outside the reflux pipe 15 so as to be adjacent to the fitting end 152 of the reflux pipe 15 absorbs the thermal energy of the gas working liquid 13 and simultaneously diffuses it into the air. At this time, the gas hydraulic fluid 13 condenses the water droplet-like liquid hydraulic fluid 13 by the cooling action of the heat radiating member 100. As shown in FIG. 4, the liquid bullet 131 is generated when the aggregated water droplet-like liquid hydraulic fluid 13 increases. If the liquid bullet 131 is moved forward by the pressure difference, the liquid hydraulic fluid 13 can easily return to the evaporation chamber 11 and can smoothly return to the evaporation chamber 11 to improve the heat radiation efficiency. Such a circulation action can continuously induce the heat energy of the electronic device and achieve a good heat dissipation effect.

（第２実施形態）
図６から図８に示したのは第２実施形態による同じ管路が気流流路および液流流路に仕切られた還流ヒートパイプ２０である。第１実施形態との違いは下記のとおりである。 (Second Embodiment)
6 to 8 show a reflux heat pipe 20 in which the same pipe line according to the second embodiment is partitioned into an air flow channel and a liquid flow channel. Differences from the first embodiment are as follows.

第２実施形態において、還流管２５は内部に三つのスペーサー２６を有する。三つのスペーサー２６は断面が人字型であり、還流管２５を二つの気流流路２７および一つの液流流路２８に仕切る。二つの気流流路２７および一つの液流流路２８は還流管２５内に相互に連絡しない。三つのスペーサー２６を製作する際、三つのスペーサー２６および還流管２５は一体成型されてもよい。   In the second embodiment, the reflux pipe 25 has three spacers 26 inside. The three spacers 26 are human-shaped in cross section, and partition the reflux pipe 25 into two air flow channels 27 and one liquid flow channel 28. The two air flow channels 27 and the one liquid flow channel 28 do not communicate with each other in the reflux pipe 25. When the three spacers 26 are manufactured, the three spacers 26 and the reflux pipe 25 may be integrally formed.

第２実施形態において、毛細管材２２は還流管２５の液流流路２８に対応する延長部２２３を有する。図８に示すように、延長部２２３は扇形を呈し、液流流路２８内の所定長さまで入り込んで蒸発チャンバー２４と液流流路２８の間の流路を遮断し、気体作動液が液流流路２８へ流入することを抑制することができる。延長部２２３は上述に限定されず、本発明に必要な部材でないため、配置されなくてもよい。   In the second embodiment, the capillary material 22 has an extension 223 corresponding to the liquid flow channel 28 of the reflux pipe 25.
