以下、実施例にて本考案について更に説明する。   Hereinafter, the present invention will be further described with reference to examples.

実施例１
金属製放熱装置は、図１に示されるように、金属製ベース１００が設置され、金属製ベース１００の内部に複数の放熱通路２００が設置される。 Example 1
As shown in FIG. 1, the metal heat dissipating device is provided with a metal base 100, and a plurality of heat dissipating passages 200 are provided inside the metal base 100.

金属製ベース１００はアルミベースであり、両端が密閉されるように配置され、具体的に、端部を圧着又はレーザー溶接して密封接続を実現する。   The metal base 100 is an aluminum base and is arranged so that both ends are sealed. Specifically, the end portion is crimped or laser welded to realize a sealed connection.

なお、金属製ベース１００は、好ましくは、放熱性能に優れた材質であり、アルミベース以外、銅ベース、チタンベース又は銀ベースも使用できる。   The metal base 100 is preferably made of a material excellent in heat dissipation performance, and a copper base, a titanium base, or a silver base can be used in addition to the aluminum base.

複数の放熱通路２００は、金属製ベース１００の両端位置で密封され、それぞれの内部が真空状態になり、内部に液体作動流体が注入されており、且つ各放熱通路２００の内壁面に規則又は非規則的に配列された毛管機能層２２０が設置されている。   The plurality of heat radiation passages 200 are sealed at both end positions of the metal base 100, the insides thereof are in a vacuum state, the liquid working fluid is injected therein, and the inner wall surfaces of the heat radiation passages 200 are either regular or non-circular. A regularly arranged capillary functional layer 220 is provided.

金属製ベース１００が加熱されるとき、被加熱部位に対応した放熱通路２００の被加熱端にある液体作動流体が加熱されてガス化し、ガス化された気体が放熱通路２００の遠端へ流れて、放熱通路２００の遠端で気体が予冷により液化され、液化による液体作動流体は毛管機能層２２０の作用により遠端から徐々に被加熱端へ戻り、このように連続的にサイクルして、熱量を被加熱端から遠端へ伝達して放熱させる。   When the metal base 100 is heated, the liquid working fluid at the heated end of the heat radiation passage 200 corresponding to the heated portion is heated and gasified, and the gasified gas flows to the far end of the heat radiation passage 200. The gas is liquefied by pre-cooling at the far end of the heat radiation passage 200, and the liquid working fluid resulting from the liquefaction gradually returns from the far end to the heated end by the action of the capillary functional layer 220. Is transmitted from the heated end to the far end to dissipate heat.

具体的に、各放熱通路２００に注入される液体作動流体は冷媒媒体であり、好ましくは液体作動流体媒体である。放熱通路２００にある冷媒媒体の作用により、放熱効率が高まる。冷媒とは、吸熱して気体になったり、放熱して液体になったりすることが発生しやすい物質であり、冷媒媒体の原料としては、たとえば、フロン、クロロフルオロカーボン等の複数種があるが、ここで詳細な説明を省略する。   Specifically, the liquid working fluid injected into each heat radiation passage 200 is a refrigerant medium, preferably a liquid working fluid medium. The heat radiation efficiency is increased by the action of the refrigerant medium in the heat radiation passage 200. Refrigerant is a substance that easily absorbs heat and becomes a gas, or dissipates heat and becomes a liquid, and as a raw material of the refrigerant medium, for example, there are a plurality of types such as Freon and chlorofluorocarbon, Detailed description is omitted here.

本実施例では、放熱通路２００の断面は半円形である。なお、放熱通路２００の形状は本実施例の半円形に制限されず、円形、楕円形、長方形、正方形、三角形又は不規則形状としてもよい。   In the present embodiment, the heat dissipation passage 200 has a semicircular cross section. The shape of the heat radiation passage 200 is not limited to the semicircular shape of the present embodiment, and may be a circle, an ellipse, a rectangle, a square, a triangle, or an irregular shape.

具体的に、毛管機能層２２０は、放熱通路２００の内壁面に付着した貼付け面と、貼付け面に付着したハニカム層とを少なくとも含む。貼付け面の金属粒子の粒子径が０．１〜０．１５ｎｍ、貼付け面の厚みが０．０１〜０．０５ｍｍであり、ハニカム層は、金属粒子が接続されて複数の間隙構造を有する骨格を構成し、骨格を構成する金属粒子の粒子径が０．２〜０．５ｎｍ、ハニカム層の厚みが１．５〜４．５ｎｍである。貼付け面を設置することにより、放熱通路２００の内壁面とよく貼り付けることが可能になる。ハニカム層を設置することにより、間隙は接触面積を向上させるとともに、液体貯蔵空間を提供し、数秒間だけで蒸散させるような効率を実現できる。毛管機能層２２０は、めっきプロセスにより製造された銅粉構造層である。   Specifically, the capillary functional layer 220 includes at least a sticking surface attached to the inner wall surface of the heat radiation passage 200 and a honeycomb layer attached to the sticking surface. The particle diameter of the metal particles on the affixed surface is 0.1 to 0.15 nm, the thickness of the affixed surface is 0.01 to 0.05 mm, and the honeycomb layer has a skeleton having a plurality of gap structures to which the metal particles are connected. The particle diameter of the metal particles constituting the skeleton is 0.2 to 0.5 nm, and the thickness of the honeycomb layer is 1.5 to 4.5 nm. By installing the affixing surface, it becomes possible to affix well to the inner wall surface of the heat dissipation passage 200. By installing a honeycomb layer, the gap can improve the contact area and provide a liquid storage space, so that the efficiency of evaporating in just a few seconds can be realized. The capillary functional layer 220 is a copper powder structure layer manufactured by a plating process.

該金属製放熱装置を使用するとき、ベースの一面がたとえば回路基板等の熱源に取り付けられ、熱源が作動するときに生じた熱量が放熱ベースに伝達されて、被加熱部位に対応した放熱通路２００の被加熱端にある液体作動流体が加熱されてガス化し、ガス化された気体が放熱通路２００の遠端へ流れて、放熱通路２００の遠端で気体が予冷により液化され、液化による液体作動流体は毛管機能層２２０の作用により遠端から徐々に被加熱端に戻り、このように連続的にサイクルして、熱量を被加熱端から遠端に伝達して放散させる。   When using the metal heat dissipating device, one surface of the base is attached to a heat source such as a circuit board, and the heat generated when the heat source is operated is transmitted to the heat dissipating base, and the heat dissipating passage 200 corresponding to the heated portion. The liquid working fluid at the heated end of the gas is heated and gasified, the gasified gas flows to the far end of the heat radiation passage 200, the gas is liquefied by pre-cooling at the far end of the heat radiation passage 200, and the liquid operation by liquefaction The fluid gradually returns from the far end to the heated end due to the action of the capillary functional layer 220, and continuously cycles in this way, thereby transferring the amount of heat from the heated end to the far end and dissipating it.

実験の結果、本考案に係る金属製放熱装置は、小型化の要件を実現でき、数秒間だけで放熱させるような効率を有し、熱効果が高いことが確認された。   As a result of the experiment, it was confirmed that the metal heat dissipating device according to the present invention can realize the requirement for miniaturization, has an efficiency of dissipating heat in only a few seconds, and has a high thermal effect.

As shown in FIG. 2 and FIG. 3, the cross section of the heat dissipation passage 200 is rectangular, the sawtooth surface 210 is installed on the inner surface of the heat dissipation passage 200, and the capillary functional layer 220 is positioned on the surface of the sawtooth surface 210, The remaining structure of the metal heat dissipation device is the same as that of the first embodiment. By installing the sawtooth surface 210, the adhesion area of the capillary function layer 220 of the heat radiation passage 200 is increased, and the heat radiation efficiency is improved.

鋸歯面２１０を構成する歯の断面は、三角形、長方形、半円形、円弧形又は不規則形状であり、鋸歯面２１０を構成する歯の形状は、同じで又は異なり、鋸歯面２１０を構成する歯の大きさは同じで又は異なる。   The cross-sections of the teeth constituting the sawtooth surface 210 are triangular, rectangular, semicircular, arc shape or irregular shape, and the tooth shapes constituting the sawtooth surface 210 are the same or different and constitute the sawtooth surface 210. The size of the teeth is the same or different.

実施例３
図４に示されるように、放熱通路２００の断面は平行四辺形で、且つ放熱通路２００の内表面の各面に鋸歯面２１０が設置され、毛管機能層２２０は鋸歯面２１０の表面に位置する以外、金属製放熱装置の残りの構造は実施例２と同様である。鋸歯面２１０の設置により、放熱通路２００の毛管機能層２２０の付着面積は増大して、放熱効率は向上する。 Example 3

実施例４
図５に示されるように、金属製ベース１００の表面に固定された複数群の放熱フィン３００が設置される以外、金属製放熱装置の残りの構造は実施例１又は２又は３と同様である。 Example 4
As shown in FIG. 5, the remaining structure of the metal heat dissipating device is the same as that of the first, second, or third embodiment except that a plurality of groups of heat dissipating fins 300 fixed to the surface of the metal base 100 are installed. .

各群の放熱フィン３００は、リブ３１０と、リブ３１０の両側に位置する第１側面３２０及び第２側面３３０とが設置され、リブ３１０が金属製ベース１００に接続された接続線はリブ３１０の延長線として定義され、リブ３１０を通り且つ延長線に垂直な断面はリブ３１０の正面断面として定義される。   In each group of radiating fins 300, ribs 310, first side surfaces 320 and second side surfaces 330 located on both sides of the ribs 310 are installed, and the connection lines where the ribs 310 are connected to the metal base 100 are the ribs 310. A cross section defined as an extension line and passing through the rib 310 and perpendicular to the extension line is defined as a front cross section of the rib 310.

いずれか２つのリブ３１０の間に位置するリブ３１０は中間リブ３１０として定義され、中間リブ３１０の正面断面の両側の第１側面３２０と第２側面３３０に対応した位置が鋸歯状構造３４０をしており、外部両側に位置するリブ３１０の正面断面の隣接リブ３１０寄りの一面が鋸歯状構造３４０をしている。   The rib 310 positioned between any two ribs 310 is defined as the intermediate rib 310, and the positions corresponding to the first side surface 320 and the second side surface 330 on both sides of the front cross section of the intermediate rib 310 form the sawtooth structure 340. One surface near the adjacent rib 310 in the front cross section of the rib 310 located on both sides of the outside forms a sawtooth structure 340.

本実例の金属製放熱装置では、複数群の放熱フィン３００は平行に配列されている。なお、実際に使用されるとき、放熱フィン３００は、平行に配列される形態に制限されず、必要に応じて、非平行に配列されてもよい。   In the metal heat dissipating device of this example, a plurality of groups of heat dissipating fins 300 are arranged in parallel. When actually used, the radiating fins 300 are not limited to the form arranged in parallel, and may be arranged non-parallel as necessary.

該金属製放熱装置を使用するとき、金属製ベース１００の一面がたとえば回路基板等の熱源に取り付けられ、熱源が作動するときに生じた熱量が金属製ベース１００に伝達されて、被加熱部位に対応した放熱通路２００の被加熱端にある液体作動流体が加熱されてガス化し、ガス化された気体が放熱通路２００の遠端へ流れて、放熱通路２００の遠端で気体が予冷により液化され、液化による液体作動流体は毛管機能層２２０の作用により遠端から徐々に被加熱端に戻り、このように連続的にサイクルして、熱量を被加熱端から放熱フィン３００に伝達して、放熱フィン３００から放散させる。放熱フィン３００の表面を鋸歯状に設置することは、熱量の放散に役立ち、放熱効率が高いという特徴を有する。   When the metal heat dissipation device is used, one surface of the metal base 100 is attached to a heat source such as a circuit board, and the amount of heat generated when the heat source is operated is transmitted to the metal base 100 to be heated. The liquid working fluid at the heated end of the corresponding heat radiation path 200 is heated and gasified, the gasified gas flows to the far end of the heat radiation path 200, and the gas is liquefied by pre-cooling at the far end of the heat radiation path 200. The liquid working fluid by liquefaction gradually returns from the far end to the heated end by the action of the capillary functional layer 220, and is continuously cycled in this way to transfer the heat amount from the heated end to the heat radiating fin 300, thereby radiating heat. Dissipate from the fin 300. Installing the surface of the heat radiation fin 300 in a sawtooth shape is useful for dissipating heat and has a feature of high heat radiation efficiency.

本考案に係る金属製放熱装置は、小型化の要件を実現でき、数秒間だけで放熱させるような効率を有し、熱効果が高い。   The metal heat dissipating device according to the present invention can realize the requirements for downsizing, has an efficiency of dissipating heat in only a few seconds, and has a high thermal effect.

最後に、なお、以上の実施例は、本考案の技術案を説明するためのものに過ぎず、本考案の保護範囲を制限するものではなく、好適実施例を参照して本考案について詳細に説明したが、当業者であれば、本考案の技術案の主旨及び範囲を逸脱することなく、本考案の技術案について修正又は同等置換を行うことができることが理解できる。   Finally, the above embodiments are only for explaining the technical solutions of the present invention, and are not intended to limit the protection scope of the present invention. Although described, those skilled in the art will appreciate that modifications or equivalent replacements can be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
