Description

本発明は、放熱装置に関し、詳しくは延伸毛細管層で複数のベイパーチャンバーを連絡する統合型ベイパーチャンバーモジュールに関するものである。   The present invention relates to a heat dissipation device, and more particularly to an integrated vapor chamber module that connects a plurality of vapor chambers with a stretched capillary layer.

周知の還流型ベイパーチャンバーにおいて、特許文献１により掲示された「冷却装置および電子設備」は受熱プレートになるベイパーチャンバーおよび放熱プレートになるベイパーチャンバーを気流管および液流管によって連結し、気液分離型還流ベイパーチャンバーを構成する。気流管および液流管は溶接方式によって受熱プレートおよび放熱プレートに連結される。   In a well-known reflux-type vapor chamber, “Cooling device and electronic equipment” posted in Patent Document 1 connects a vapor chamber serving as a heat receiving plate and a vapor chamber serving as a heat radiating plate by an air flow tube and a liquid flow tube to separate the gas and liquid. A mold reflux vapor chamber is constructed. The airflow pipe and the liquid flow pipe are connected to the heat receiving plate and the heat radiating plate by a welding method.

しかし、溶接加工作業は品質管理が難しく、製品の歩合を降下させるという問題がある。また溶接箇所の構造が比較的脆いため、衝撃を受けるか長時間にわたって使用されると製品の損壊を発生し、製品の使用寿命を短縮する。   However, the quality of the welding process is difficult, and there is a problem that the yield of the product is lowered. In addition, since the structure of the welded portion is relatively brittle, the product will be damaged when subjected to impact or used for a long time, and the service life of the product will be shortened.

延伸毛細管層１７は銅粉末焼結によって成形され、液流流路１１３内に位置付けられ、液流流路１１３の一部分に分布することによって気体が液流流路１１３を通らず第一凹状溝１１１および第二凹状溝１１２内を流動することを維持する。延伸毛細管層１７は両端が液流流路１１３の外側の所定距離まで突出し、二つの延伸部位１７１、１７２を有する。延伸部位１７１、１７２は別々に第一凹状溝１１１および第二凹状溝１１２に入り込み、端部が同じ側の所定の長さまで伸びる。   The stretched capillary layer 17 is formed by sintering copper powder, is positioned in the liquid flow channel 113, and is distributed in a part of the liquid flow channel 113 so that the gas does not pass through the liquid flow channel 113 and the first concave groove 111.

The two extending portions 171 and 172 are in contact with any one of the third capillary layer 15 and the fourth capillary layer 16 or are in contact with the third capillary layer 15 and the fourth capillary layer 16 as shown in FIG.

以上は第1実施形態の構造についての説明である。続いて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. Next, the description of the operating state will proceed.

延伸毛細管層で複数のベイパーチャンバーを連絡する統合型ベイパーチャンバーモジュール１０が作動する際、第一凹状溝１１１に対応する蓋１２の表面は受熱部位になる。
受熱部位は熱源に接触し、熱源に生じた熱エネルギーを吸収する。熱源はマイクロプロセッサ、集積回路、ＲＦコンポーネント、別の熱エネルギーを生じる部材またはモジュールである。モジュールは一つまたは複数の上述した部材または電子部品から構成された電子回路を含む。 When the integrated vapor chamber module 10 that connects a plurality of vapor chambers with the stretched capillary layer operates, the surface of the lid 12 corresponding to the first concave groove 111 becomes a heat receiving portion.
The heat receiving portion contacts the heat source and absorbs heat energy generated in the heat source. A heat source is a microprocessor, an integrated circuit, an RF component, another thermal energy generating member or module. The module includes an electronic circuit composed of one or more of the above-described members or electronic components.

第二凹状溝１１２に対応する蓋１２の表面は放熱部位になる。放熱部位は放熱モジュールに直接または間接に接触する。放熱部位が放熱モジュールに直接に接触する際、放熱モジュールは放熱フィンまたは放熱フィンおよびファンの組み合わせによって放熱部位に直接に接触し、放熱部位を冷却させる。放熱部位が放熱モジュールに間接に接触する際、放熱モジュールは放熱部位に接触せず、ファンの生じた気流などの流体によって放熱部位を冷却させる。別の実施形態において、放熱モジュールは上述に限らず、複数の放熱フィン、複数のファンまたは別の部材からなってもよい。   The surface of the lid 12 corresponding to the second concave groove 112 becomes a heat radiating portion. The heat dissipating part contacts the heat dissipating module directly or indirectly. When the heat dissipating part directly contacts the heat dissipating module, the heat dissipating module directly contacts the heat dissipating part by the heat dissipating fin or the combination of the heat dissipating fin and the fan, and cools the heat dissipating part. When the heat dissipating part contacts the heat dissipating module indirectly, the heat dissipating module does not contact the heat dissipating part, and the heat dissipating part is cooled by a fluid such as an air flow generated by the fan. In another embodiment, the heat dissipation module is not limited to the above, and may include a plurality of heat dissipation fins, a plurality of fans, or another member.

図５に示すように、受熱部位が熱エネルギーを吸収し、蓋１２から第一凹状溝１１へ伝送する際、第一凹状溝１１１内の液体動作流体は熱エネルギーを吸収した後蒸発して気体作動流体に変わる。続いて気体動作流動液は気流流路１１４によって放熱部位に対応する第二凹状溝１１２に流入し、降温して液体作動液に変わる。
続いて、相互に当接する第二毛細管層１４の複数の凸状部１４１および第四毛細管層１６の複数の凸状部１６１と、第二凹状溝１１２内に位置する延伸毛細管層１７の延伸部位１７２とによって冷却した液体作動液は誘導され、液流流路１１３内の延伸毛細管層１７を通って延伸毛細管層１７の別の延伸部位１７１へ迅速に前進し、第一凹状溝１１１に流入し、第三毛細管層１５に付着することができる。このとき液体作動液は第一凹状溝１１１内の延伸毛細管層１７が第三毛細管層１５および第一毛細管層１３に接触することによって受熱部位に還流する。上述した循環作用は熱源に生じた熱エネルギーを持続的に引き出し、良好な放熱効果を発揮することができる。 As shown in FIG. 5, when the heat receiving part absorbs thermal energy and transmits it from the lid 12 to the first concave groove 11, the liquid working fluid in the first concave groove 111 absorbs the thermal energy and then evaporates to become a gas. Change to working fluid. Subsequently, the gas working fluid flows into the second concave groove 112 corresponding to the heat radiating portion by the air flow channel 114 and is cooled to change into the liquid working fluid.
Subsequently, the plurality of convex portions 141 of the second capillary layer 14 and the plurality of convex portions 161 of the fourth capillary layer 16 that are in contact with each other, and the stretched portion of the stretched capillary layer 17 located in the second concave groove 112 The liquid working fluid cooled by the liquid flow channel 172 is guided, rapidly advances to another stretched portion 171 of the stretched capillary layer 17 through the stretched capillary layer 17 in the liquid flow channel 113, and flows into the first concave groove 111. The third capillary layer 15 can be attached. At this time, the liquid hydraulic fluid is refluxed to the heat receiving portion when the stretched capillary layer 17 in the first concave groove 111 comes into contact with the third capillary layer 15 and the first capillary layer 13. The above-described circulation action can continuously extract the heat energy generated in the heat source and exhibit a good heat dissipation effect.

As shown in FIG. 12, the difference between the fifth embodiment and the first embodiment is that the first capillary layer 13 and the fourth capillary layer 16 in FIG. 4 are deleted from the capillary structure.
An integrated vapor chamber module 50 that communicates a plurality of vapor chambers with a stretched capillary layer according to a fifth embodiment of the present invention includes a base 51, a lid 52, a stretched capillary layer 57, and a capillary structure.

Since the other structures of the fifth embodiment and the effects that can be achieved are the same as those of the first embodiment, detailed description thereof is omitted.

図１２に示すように、第５実施形態は図４に示した第１実施形態と比べて毛細管構造の層が少ない。毛細管構造の配置方式は上述に限らず、層が増減してもよい。層が比較的多い毛細管構造は毛細管層部位を分化し、多層構造を形成することができる。   As shown in FIG. 12, the fifth embodiment has fewer layers of capillary structure than the first embodiment shown in FIG. The arrangement method of the capillary structure is not limited to the above, and the number of layers may be increased or decreased.
