Description

本発明は、放熱性に優れた放熱部材、および、その放熱部材を用いた装置、筐体、コンピュータ支持台、放熱部材製造方法に関する。  The present invention relates to a heat radiating member excellent in heat dissipation, and an apparatus, a casing, a computer support base, and a method for manufacturing the heat radiating member using the heat radiating member.

従来より、内燃機関や、冷蔵庫をはじめとする熱交換機、コンピュータのCPU等の電子デバイス等の熱が発生する装置は、その放熱を司る放熱部、たとえば、放熱フィンや内燃機関等のマフラー、各種電動モータ、ヒートシンクなどを、黒色塗装を施して放熱効果を向上させている。  Conventionally, heat generating devices such as internal combustion engines, heat exchangers such as refrigerators, electronic devices such as computer CPUs, etc. are used for heat dissipation, such as mufflers such as heat dissipation fins and internal combustion engines, Electric motors, heat sinks, etc. are painted black to improve the heat dissipation effect.

しかしながら、黒色塗装を施したのみでは、さらなる放熱効果の向上は期待できないため、上記したような、熱が発生する多種多様な装置は、放熱部の構造に工夫(例えば熱対流を促進させる構造など)を加え、放熱効果の向上を果たしている。  However, since it is not possible to expect further improvement of the heat dissipation effect only by applying black paint, the various devices that generate heat as described above are devised in the structure of the heat dissipation part (for example, a structure that promotes thermal convection, etc. ) To improve the heat dissipation effect.

その一例として、たとえば、電力回路を構成する複数のバスバーを具備する回路構成体を、絶縁層がコーティングされたバスバー接着面を有した放熱部材を備え、このバスバー接着面上に前記複数本のバスバーが並べられた状態で当該バスバー接着面に各バスバーが直接接着することで、簡単な構造で、バスバーを効率良く冷却する、としている(例えば特開2003−164040号公報参照)。  As an example, for example, a circuit structure including a plurality of bus bars constituting a power circuit is provided with a heat dissipating member having a bus bar bonding surface coated with an insulating layer, and the plurality of bus bars are provided on the bus bar bonding surface. In this state, the bus bars are directly bonded to the bus bar bonding surface, whereby the bus bars are efficiently cooled with a simple structure (see, for example, Japanese Patent Application Laid-Open No. 2003-164040).

また、他の例として、電流分配用回路板とプリント基板とを空隙をあけた状態で支持し、介在させる絶縁板を廃止すると共に、空隙の存在により放熱性を向上させた電気接続箱等があげられる(例えば特開2003−87938号公報参照)。  As another example, there is an electrical junction box that supports the current distribution circuit board and the printed circuit board with a gap therebetween, eliminates the intervening insulating plate, and improves heat dissipation due to the presence of the gap. (See, for example, JP-A-2003-87938).

以上、放熱効果を向上させるため構造に特徴を持たせた一例を例示したが、さらなる放熱効果の向上を果たすには、部材そのものを見直す必要がある。  As mentioned above, although the example which gave the structure the characteristic in order to improve the heat dissipation effect was illustrated, in order to achieve the further improvement of the heat dissipation effect, it is necessary to review the member itself.

しかしながら、材質自体を改良させて物性である熱伝導率を向上させることは極めて困難である。  However, it is extremely difficult to improve the thermal conductivity, which is a physical property, by improving the material itself.

そこで、上述したように、放熱および吸熱の効果がある黒色塗装を、熱伝導率が高い銅やアルミニウム等の基材に施しているわけではあるが、本発明は、その黒色塗装を基材に施した放熱部材よりも、さらなる放熱効果が期待できる放熱部材と、その放熱部材を用いた装置、筐体、コンピュータ支持台、放熱部材製造方法を提供することを目的とする。  Therefore, as described above, the black coating having the effect of heat dissipation and heat absorption is applied to a base material such as copper or aluminum having a high thermal conductivity, but the present invention uses the black coating as a base material. It is an object of the present invention to provide a heat dissipating member that can be expected to have a further heat dissipating effect than the applied heat dissipating member, and a device, a casing, a computer support, and a heat dissipating member manufacturing method using the heat dissipating member.

本発明をより詳細に説明するために、添付図面を参照してこれを説明する。  For a more detailed description of the present invention, reference will now be made to the accompanying drawings.

図中、符号1は、放熱部材を、符号11は基材を、符号12はトルマリン層を示す。  In the figure, reference numeral 1 denotes a heat radiating member, reference numeral 11 denotes a base material, and reference numeral 12 denotes a tourmaline layer.

(実施の形態1)
本実施の形態にかかる放熱部材1は、図1に示すように、熱伝導率の高い銅の薄板(板厚0.8mm)からなる基材11と、その基材11の上面に塗着されショールトルマリン粉末を主成分としたトルマリン層12とを備えてなる。
(Embodiment 1)
As shown in FIG. 1, the heat radiating member 1 according to the present embodiment is applied to a base material 11 made of a copper thin plate (plate thickness: 0.8 mm) having high thermal conductivity, and an upper surface of the base material 11. And a tourmaline layer 12 mainly composed of shoal tourmaline powder.

このトルマリン層12は、粒径が概ね6μmのショールトルマリン粉末と、アクリル系の揮発性合成樹脂塗料からなる固定剤とを、その重量比1:1の割合で混和(塗布剤生成工程)して塗布剤を生成し、その塗布剤を、ショールトルマリン粉末が1平方cmあたり0.025〜0.05グラムの面密度となるように基材11に多重塗り(塗布工程)して固化させて形成されている。
The tourmaline layer 12 is prepared by mixing a shoal tourmaline powder having a particle size of approximately 6 μm and a fixing agent made of an acrylic volatile synthetic resin paint at a weight ratio of 1: 1 (coating agent generation step). A coating agent is produced, and the coating agent is formed by multiple coating (coating process) on the substrate 11 so that the surface density of the shawl tourmaline powder is 0.025 to 0.05 gram per square centimeter, and solidified. Has been.

なお、ドラバイトトルマリン、ショールトルマリン、ミックストルマリン、リチアトルマリン等の代表的なトルマリンを用いて放熱に関する予備試験を行い、最も放熱効果があった黒色をしたショールトルマリンを採用している。  In addition, preliminary tests on heat dissipation were conducted using typical tourmalines such as drabbit tourmaline, shawl tourmaline, mixed tourmaline, lithia tourmaline, etc., and black shawl tourmaline with the most heat dissipation effect was adopted.

そもそも、トルマリンがイオンをだす、或いは電気を発生する、という事は周知のことであるが、エネルギ不変の法則から、トルマリンがイオンや電気を出力するためには何らかの入力エネルギが必要であり、本発明の効果から推察すると、熱エネルギをイオンや電気に転化しているものと思われる。  In the first place, it is well-known that tourmaline generates ions or generates electricity, but from the law of energy invariance, some input energy is required for tourmaline to output ions and electricity. Inferring from the effects of the invention, it is considered that heat energy is converted into ions and electricity.

したがって、電極間の電圧が高いショールトルマリンが最も放熱効果があったものと推定している。  Therefore, it is estimated that the shawl tourmaline having a high voltage between the electrodes has the most heat radiation effect.

また、固定剤とショールトルマリン粉末との重量比1:1としたのは、固定剤が乾燥して固化した際に、ショールトルマリン粉末が緊密な状態を保つのに好バランスであることが実験から確認されており、固定剤をショールトルマリン粉末より少なくすると基材から剥離しやすくなり、固定剤をショールトルマリン粉末より多くすると、所望したショールトルマリンの面密度となるまで多重塗りすることになり施工性が悪い。因みに20gの液状状態のアクリル系の揮発性合成樹脂塗料が、乾燥すると4gとなっている。
Moreover, the weight ratio of the fixative to the shoal tourmaline powder was set to 1: 1 because the experiment shows that the shoal tourmaline powder has a good balance in maintaining a tight state when the fixative is dried and solidified. It has been confirmed that if the fixing agent is less than the shawl tourmaline powder, it will be easy to peel off from the base material, and if the fixing agent is more than the shawl tourmaline powder, multiple coatings will be applied until the surface density of the desired shawl tourmaline is reached Is bad. Incidentally, 20 g of liquid acrylic volatile synthetic resin paint is 4 g when dried.

さらに、このトルマリン層12は、最も放熱効果があった上記したショールトルマリンについて、さらに、粒径別選定実験、塗布量選定実験、固定剤選定実験を行い、その実験結果から際だって優れたデータに基づいて構成している。その各選定実験の詳細は後述する。  Furthermore, this tourmaline layer 12 further performs a selection experiment according to particle size, an application amount selection experiment, and a fixative selection experiment on the above-described shawl tourmaline, which has the most heat dissipation effect, and the results of the experiment show outstanding data. Based on the configuration. Details of each selection experiment will be described later.

また、このショールトルマリン粉末を混入させる液体は、上記したアクリル系の揮発性合成樹脂塗料に限定されず、水性エマルジョン系塗料、二液混合エポキシ塗料などの周知の耐熱塗料でも良いものであり、すなわち、固化し、かつ、基材11から容易に剥離しない(長期に亘って塗着状態を維持)ものであれば、いずれの液状物でも良い。  Further, the liquid in which the shoal tourmaline powder is mixed is not limited to the acrylic volatile synthetic resin paint described above, and may be a well-known heat resistant paint such as an aqueous emulsion paint or a two-component mixed epoxy paint, Any liquid material may be used as long as it solidifies and does not easily peel from the substrate 11 (maintains the coating state over a long period of time).

また、溶融状態のアルミニウムやプラスチックの基材に、粒径が概ね3〜7μmのショールトルマリン粉末を混和して所望の形状に固化させても良い。  Further, a shoal tourmaline powder having a particle size of approximately 3 to 7 μm may be mixed into a molten aluminum or plastic base material and solidified into a desired shape.

なお、トルマリン(ショールトルマリンに限らない)は、900℃以上の熱を加えると破壊してしまうので、熱伝導の優れると共に融点が660℃であるアルミニウムが、上記したように基材自体にショールトルマリン粉末を含有させる場合において最も好適な部材である。  Note that tourmaline (not limited to shawl tourmaline) is destroyed when heat of 900 ° C. or higher is applied. Therefore, aluminum having excellent heat conduction and a melting point of 660 ° C. is formed on the substrate itself as described above. This is the most suitable member when powder is contained.

また、プラスチックの基材自体にショールトルマリン粉末を含有させる場合、ペレットとショールトルマリン粉末とを重量比、概ね10%の割合で混和し、一般的な射出成形などの従来の成形手段をそのまま用いて所望形状の放熱部材が製造できる。  In addition, when the plastic substrate itself contains the shoal tourmaline powder, the pellet and the shoal tourmaline powder are mixed at a weight ratio of approximately 10%, and a conventional molding method such as general injection molding is used as it is. A heat radiating member having a desired shape can be manufactured.

次に、以上のように構成された本実施の形態にかかる放熱部材1を用いた放熱実験について説明する。  Next, a heat radiation experiment using the heat radiating member 1 according to the present embodiment configured as described above will be described.

なお、実験の際に、比較対象として、0.8mm銅板の基材11の上面にのみ黒色塗装を施したもの(以下、比較試料A)と、その基材11そのままのもの(以下、比較試料B)とを用い、本実施の形態にかかる放熱部材との放熱状態を比較した。  In addition, in the experiment, as a comparison object, a material in which a black coating is applied only to the upper surface of a base material 11 of a 0.8 mm copper plate (hereinafter referred to as a comparative sample A) and a base material 11 as it is (hereinafter referred to as a comparative sample). B) and the heat dissipation state with the heat dissipation member according to the present embodiment were compared.

実験の概要は、図2に示したように、トルマリン層12や黒色塗装面とは反対側の面の一端部(比較試料Bのみ、温度センサー貼付面の方向性無し)に温度センサーCを貼付し、この放熱部材1と、比較試料Aまたは比較試料Bのいずれか選んで、家庭用電熱器(ホットプレート)Dの上に2つ同時に載置する。このとき、トルマリン層12や黒色塗装が上方となるように、また、温度センサーCが家庭用電熱器D自体の熱の影響を受けないように、電熱器から遠ざけるように、放熱部材1や比較試料A、比較試料Bを家庭用電熱器Dに載置している。  As shown in FIG. 2, the outline of the experiment is as follows. The temperature sensor C is attached to one end of the surface opposite to the tourmaline layer 12 or the black painted surface (only the comparative sample B, no directionality of the temperature sensor application surface). Then, the heat radiating member 1 and either the comparative sample A or the comparative sample B are selected, and two are placed on the household electric heater (hot plate) D at the same time. At this time, the heat dissipating member 1 and the comparison are made so that the tourmaline layer 12 and the black paint are on the upper side, and the temperature sensor C is away from the electric heater so as not to be affected by the heat of the household electric heater D itself. Sample A and comparative sample B are placed on a home electric heater D.

そして、家庭用電熱器Dを通電させることで、家庭用電熱器Dの上に載置したこれらものを、適当な温度に上昇させていき、そのときの家庭用電熱器Dから離れた温度上昇を計測することで、上面から放熱される状態が把握できる。すなわち、基材11自体の材質、載置条件、加熱条件を揃えているため、基材11表面に形成された黒色塗装層、トルマリン層12、形成層なし、各部材の放熱効果が把握できる。  Then, by energizing the home electric heater D, those placed on the home electric heater D are raised to an appropriate temperature, and the temperature rise away from the home electric heater D at that time. By measuring, the state of heat radiation from the upper surface can be grasped. That is, since the material of the base material 11 itself, mounting conditions, and heating conditions are aligned, the black paint layer formed on the surface of the base material 11, the tourmaline layer 12, no formation layer, and the heat dissipation effect of each member can be grasped.

このような条件のもとで、まず、放熱部材1と比較試料A、比較試料Bとの放熱の実験結果を説明する。  Under such conditions, first, an experimental result of heat radiation between the heat radiation member 1 and the comparative sample A and the comparative sample B will be described.

まず、放熱部材1と比較試料Bを同時条件のもとで温度計測したところ、放熱部材1が43.5℃であったのに対し、比較試料Bは、51.7℃であった。その温度差は、8.2℃あり、放熱部材1の方が放熱効果があることが認められた。  First, when the temperature of the heat radiating member 1 and the comparative sample B was measured under the same conditions, the heat radiating member 1 was 43.5 ° C., whereas the comparative sample B was 51.7 ° C. The temperature difference was 8.2 ° C., and it was confirmed that the heat dissipating member 1 had a heat dissipating effect.

次に、放熱部材1と比較試料Aを同時条件のもとで温度計測したところ、放熱部材1が54.5℃であったのに対し、比較試料Aは、57.8℃であった。その温度差は、3.3℃あり、放熱部材1の方が放熱効果があることが認められた。  Next, when the temperature of the heat radiating member 1 and the comparative sample A was measured under the same conditions, the heat radiating member 1 was 54.5 ° C., whereas the comparative sample A was 57.8 ° C. The temperature difference was 3.3 ° C., and it was confirmed that the heat dissipating member 1 had a heat dissipating effect.

以上のことから、本実施形態にかかる放熱部材1は、比較試料Aおよび比較試料Bよりも放熱効果があることが認められた。また、本実施の形態にかかる放熱部材1は、薄板状に構成したことから、切断加工や折り曲げ加工が容易であり、さまざまな放熱部分に適するように加工することができる。  From the above, it was confirmed that the heat dissipating member 1 according to the present embodiment has a heat dissipating effect than the comparative sample A and the comparative sample B. Moreover, since the heat radiating member 1 concerning this Embodiment was comprised in the shape of a thin plate, a cutting process and a bending process are easy and can be processed so that it may be suitable for various heat radiating parts.

次に、上記した本実施の形態にかかる放熱部材のショールトルマリンを用いたトルマリン層を選定するために実施された、粒径別選定実験、塗布量選定実験、固定剤選定実験について詳細に説明する。  Next, the selection experiment by particle size, the coating amount selection experiment, and the fixing agent selection experiment conducted in order to select the tourmaline layer using the shawl tourmaline of the heat dissipation member according to the above-described embodiment will be described in detail. .

1.粒径別選定実験
ショールトルマリンの粒径別の放熱効果について説明する。
1. Selection Experiment by Particle Size The heat radiation effect by the particle size of shawl tourmaline will be described.

供試体である放熱部材M2は、ショールトルマリンの粒径が、1.2μm、3μm、325メッシュ、6μmの夫々のショールトルマリン粉末を、アクリル系の揮発性合成樹脂塗料からなる固定剤に、重量比1:1の割合(30g:30g)で混和して、4つの試料用塗布剤を生成し、大きさ(縦幅×横幅×厚み)300×200×0.8mmの銅板の一表面に、1平方cmあたり、夫々のショールトルマリンの面密度が0.05グラムとなるように塗布(一表面を塗りきる)して、4つの試料用の放熱部材M2を用意する。
The heat-dissipating member M2, which is a specimen, has a shawl tourmaline particle size of 1.2 μm, 3 μm, 325 mesh, and 6 μm as a fixing agent made of an acrylic volatile synthetic resin paint. Mixing at a ratio of 1: 1 (30 g: 30 g) to produce four sample coating agents, on one surface of a copper plate having a size (length × width × thickness) 300 × 200 × 0.8 mm, 1 Coating is performed so that the surface density of each shawl tourmaline is 0.05 grams per square centimeter (one surface is completely painted), and four heat radiation members M2 for samples are prepared.

そして、図8及び図9に示すように、サーモスタット付きの電熱器の上に、大きさ(縦幅×横幅×厚み)200×300×0.8mmの銅板M1を載置し、その銅板M1の上に、試料用の放熱部材M2を下部同士を揃えるように、かつ、トルマリン層が上側となるように載置する。  And as shown in FIG.8 and FIG.9, on the electric heater with a thermostat, the magnitude | size (vertical width x horizontal width x thickness) 200x300x0.8mm copper plate M1 is mounted, The copper plate M1 of On the top, the heat dissipating member M2 for the sample is placed so that the lower portions are aligned and the tourmaline layer is on the upper side.

そして、銅板M1の右端中央部より内側に10mmずれた位置と、放熱部材M2の上部中央部より内側に10mmずれた位置(トルマリン層側)とに、温度計測装置S2に接続された温度センサーS1を貼付する。  And temperature sensor S1 connected to temperature measuring device S2 in the position shifted 10mm inward from the center part of the right end of copper plate M1 and the position (tourmaline layer side) shifted 10mm inward from the upper center part of heat dissipation member M2 Affix.

そして、電熱器D1の温度設定に50℃に設定し、予熱時間として約1時間を経過した後、銅板M1と、供試体である放熱部材M2の温度を15秒おきに計測した(なお、電熱器を4つ用意し、4つの銅板と供試用放熱部材とを同時に計測している)。  Then, the temperature setting of the electric heater D1 was set to 50 ° C., and after about 1 hour as a preheating time, the temperature of the copper plate M1 and the heat radiating member M2 as the specimen was measured every 15 seconds (in addition, the electric heating Four instruments are prepared, and four copper plates and a test heat radiation member are measured simultaneously).

上記の条件のもと、得られた実験結果を下表に示す。各表における右側最下欄部以外においては、15秒ごとに測定された温度が示されており、tで示された欄に示された値はこの経過時間(分)である。なお、各表の右側最下欄部は、供試用放熱部材の平均温度、銅板の平均温度、銅板の平均温度から供試用放熱部材の平均温度を引いて算出した平均温度差を示す。
The experimental results obtained under the above conditions are shown in the following table. In the tables other than the rightmost bottom column, the temperature measured every 15 seconds is shown, and the value shown in the column indicated by t is this elapsed time (minutes). In addition, the lower right column part of each table | surface shows the average temperature difference which subtracted the average temperature of the heat radiating member for a test from the average temperature of the heat radiating member for a test, the average temperature of a copper plate, and the average temperature of a copper plate.

以上のことから、ショールトルマリンの粒径が6μmの供試用の放熱部材が10分間の平均温度差5.24℃が最も高く、これに続いて、3μmが4.48℃、325メッシュが4.39℃、1.2μmが2.95℃の実験結果が得られた。このことから、ショールトルマリンの粒径が6μmをピークに3μmあたりから際だった放熱効果が得られ、粒径が6μmより大きく(325メッシュ)なると、僅かながら放熱効果の減少が認められた。したがって、基材との一体感(塗着力)や、表面粗さ(液状の固定剤が乾燥するとショールトルマリンによって微細な凹凸が形成される)をなるべく小さくしたいことを考慮すると、最低3μmから最大で325メッシュの範囲のショールトルマリンが好適である。特に、放熱効果が最も高く、かつ、実用上問題のない表面粗さが得られる粒径が概ね6μmのショールトルマリンが極めて好適である。
From the above, the heat dissipation member for test with a particle size of shoal tourmaline has the highest average temperature difference of 5.24 ° C. for 10 minutes, followed by 4.48 ° C. at 3 μm and 4. An experimental result of 39 ° C. and 1.2 μm of 2.95 ° C. was obtained. From this, a remarkable heat dissipation effect was obtained from around 3 μm with the peak particle size of shoal tourmaline being 6 μm, and when the particle size was larger than 6 μm (325 mesh), a slight decrease in the heat dissipation effect was recognized. Therefore, considering that we want to minimize the sense of unity (coating power) with the base material and the surface roughness (fine irregularities are formed by shawl tourmaline when the liquid fixative is dried), the minimum is 3 μm to the maximum. A shawl tourmaline in the range of 325 mesh is preferred. In particular, shawl tourmaline having a particle size of approximately 6 μm, which has the highest heat dissipation effect and provides a practically satisfactory surface roughness, is extremely suitable.

2.塗布量選定実験
次にショールトルマリンの塗布量別の放熱効果について説明する。

供試体である放熱部材は、ショールトルマリンの粒径が6μmのショールトルマリン粉末とし、アクリル系の揮発性合成樹脂塗料からなる固定剤に、重量比1:1の割合(9g:9g、15g:15g、30g:30g、60g:60g)で混和して、4つの試料用塗布剤を生成し、大きさ(縦幅×横幅×厚み)300×200×0.8mmの銅板の一表面(片面のみ)に、全ての塗りきって、面密度の異なる4つの試料用の放熱部材を用意する。すなわち、1平方cm当たりの密度は0.015g、0.025g、0.05g、0.1gとなる。
The heat radiating member, which is a specimen, is a shawl tourmaline powder having a particle size of 6 μm, which is a ratio of 1: 1 (9 g: 9 g, 15 g: 15 g) to a fixing agent made of an acrylic volatile synthetic resin paint. , 30 g: 30 g, 60 g: 60 g) to produce four sample coating agents, one surface (only one side) of a copper plate having a size (length × width × thickness) 300 × 200 × 0.8 mm In addition, four heat dissipating members for samples having different surface densities are prepared. That is, the density per square cm is 0.015 g, 0.025 g, 0.05 g, and 0.1 g.

そして、粒径別選定実験と同じように、サーモスタット付きの電熱器の上に、大きさ(縦幅×横幅×厚み)200×300×0.8mmの銅板を載置し、その銅板の上に、試料用の放熱部材を下部同士揃えるように、かつ、トルマリン層が上側となるように載置する。  Then, as in the selection experiment for each particle size, a copper plate having a size (length × width × thickness) 200 × 300 × 0.8 mm is placed on an electric heater with a thermostat, and the copper plate is placed on the copper plate. The sample heat dissipating members are placed so that the lower portions are aligned with each other, and the tourmaline layer is on the upper side.

そして、銅板の右端中央部より内側に10mmずれた位置と、放熱部材の上部中央部より内側に10mmずれた位置(トルマリン層側)とに、温度計測装置に接続された温度センサーを貼付する(図8,図9参照)。  And the temperature sensor connected to the temperature measuring device is affixed to the position displaced 10 mm inward from the central part of the right end of the copper plate and the position displaced 10 mm inward from the upper central part of the heat radiating member (tourmaline layer side) ( (See FIGS. 8 and 9).

そして、電熱器の温度設定に50℃に設定し、予熱時間として約1時間を経過した後、銅板と、供試用放熱部材の温度を15秒おきに計測した(なお、電熱器を4つ用意し、4つの銅板と供試用放熱部材とを同時に計測している)。  Then, the temperature of the electric heater was set to 50 ° C., and after about 1 hour as a preheating time, the temperature of the copper plate and the heat radiation member for test was measured every 15 seconds (in addition, four electric heaters were prepared. And four copper plates and a heat-dissipating member for test are measured simultaneously).

上記の条件のもと、得られた実験結果を下表に示す。なお、各表の右側最下欄部は、供試用放熱部材の平均温度、銅板の平均温度、銅板の平均温度から供試用放熱部材の平均温度を引いて算出した平均温度差を示す。  The experimental results obtained under the above conditions are shown in the following table. In addition, the lower right column part of each table | surface shows the average temperature difference which subtracted the average temperature of the heat radiating member for a test from the average temperature of the heat radiating member for a test, the average temperature of a copper plate, and the average temperature of a copper plate.

以上のことから、放熱効果が最も高いのが、ショールトルマリンの1平方cm当たりの面密度が、0.05g(温度差4.39℃)であり、次いで、0.025g(温度差3.3℃)、0.1g(温度差3.20)、0.015g(温度差3.18)となっている。したがって、ショールトルマリンの1平方cm当たりの面密度、0.05〜0.025gが経済的で、かつ、放熱性が高いことが確認された。
From the above, the heat radiation effect is the highest in that the surface density per square centimeter of shawl tourmaline is 0.05 g (temperature difference 4.39 ° C.), and then 0.025 g (temperature difference 3.3). ° C), 0.1 g (temperature difference 3.20), and 0.015 g (temperature difference 3.18). Therefore, it was confirmed that the surface density per square centimeter of shoal tourmaline, 0.05 to 0.025 g, is economical and has high heat dissipation.

3.固定剤選定実験
次に固定剤別の放熱効果について説明する。
3. Fixing Agent Selection Experiment Next, the heat radiation effect for each fixing agent will be described.

供試体である放熱部材は、ショールトルマリンの粒径が6μmのショールトルマリン粉末とし、アクリル系の揮発性合成樹脂塗料と、水性エマルジョン系塗料、二液混合エポキシ塗料の3種類の固定剤に、それぞれ重量比1:1の割合(30g:30g)で混和して、3つの試料用塗布剤を生成し、大きさ(縦幅×横幅×厚み)300×200×0.8mmの銅板の一表面に、1平方cmあたり、ショールトルマリンの面密度が0.05グラムとなるように塗布(一表面を塗りきる)して、3つの試料用の放熱部材を用意する。
The heat-dissipating member, which is a specimen, is a shawl tourmaline powder having a particle size of 6 μm, which is a volatile synthetic resin paint based on acrylic, an aqueous emulsion paint, and a two-component mixed epoxy paint. Mixing at a weight ratio of 1: 1 (30 g: 30 g) to produce three sample coating agents on one surface of a copper plate having a size (length × width × thickness) 300 × 200 × 0.8 mm Coating is performed so that the surface density of shawl tourmaline is 0.05 grams per square centimeter (one surface is completely coated), and three heat dissipating members for samples are prepared.

そして、粒径別選定実験と同じように、サーモスタット付きの電熱器の上に、大きさ(縦幅×横幅×厚み)200×300×0.8mmの銅板を載置し、その銅板の上に、試料用の放熱部材を下部同士を揃えるように、かつ、トルマリン層が上側となるように載置する(図8,9参照)。  Then, as in the selection experiment for each particle size, a copper plate having a size (length × width × thickness) 200 × 300 × 0.8 mm is placed on an electric heater with a thermostat, and the copper plate is placed on the copper plate. The sample heat dissipating member is placed so that the lower portions are aligned with each other and the tourmaline layer is on the upper side (see FIGS. 8 and 9).

そして、銅板の右端中央部より内側に10mmずれた位置と、放熱部材の上部中央部より内側に10mmずれた位置(トルマリン層側)とに、温度計測装置に接続された温度センサーを貼付する。  And the temperature sensor connected to the temperature measuring device is affixed to the position displaced 10 mm inward from the center part of the right end of the copper plate and the position displaced 10 mm inward from the upper center part of the heat radiating member (tourmaline layer side).

そして、電熱器の温度設定に50℃に設定し、予熱時間として約1時間を経過した後、銅板と、供試用放熱部材の温度を15秒おきに計測した(なお、電熱器を3つ用意し、3つの銅板と供試用放熱部材とを同時に計測している)。  Then, the temperature setting of the electric heater was set to 50 ° C., and after about 1 hour as a preheating time, the temperature of the copper plate and the heat radiating member for test was measured every 15 seconds (in addition, three electric heaters were prepared. And three copper plates and a heat-dissipating member for test are measured simultaneously).

上記の条件のもと、得られた実験結果を下表に示す。なお、各表の右側最下欄部は、供試用放熱部材の平均温度、銅板の平均温度、銅板の平均温度から供試用放熱部材の平均温度を引いて算出した平均温度差を示す。  The experimental results obtained under the above conditions are shown in the following table. In addition, the lower right column part of each table | surface shows the average temperature difference which subtracted the average temperature of the heat radiating member for a test from the average temperature of the heat radiating member for a test, the average temperature of a copper plate, and the average temperature of a copper plate.

以上のことから、固定剤として使用する塗料については、アクリル系の揮発性合成樹脂塗料が好適であることが確認された。  From the above, it was confirmed that an acrylic volatile synthetic resin paint is suitable for the paint used as the fixing agent.

このように、粒径別選定実験、塗布量選定実験、固定剤選定実験の結果から、粒径が概ね6μmのショールトルマリン粉末と、アクリル系の揮発性合成樹脂塗料からなる固定剤とを、その重量比1:1の割合で混和して塗布剤を生成(塗布剤生成工程)し、その塗布剤を、ショールトルマリン粉末が1平方cmあたり0.05グラムの面密度となるように基材に塗着して形成したトルマリン層が極めて好適であることが確認された。
In this way, from the results of the selection experiment by particle size, the coating amount selection experiment, and the fixing agent selection experiment, the shoal tourmaline powder having a particle size of approximately 6 μm and the fixing agent made of acrylic volatile synthetic resin paint A coating agent is produced by mixing at a weight ratio of 1: 1 (coating agent production step), and the coating agent is applied to the substrate so that the surface density of the shoal tourmaline powder is 0.05 grams per square centimeter. It was confirmed that the tourmaline layer formed by coating was extremely suitable.

(実施の形態2)
次に、放熱部材1を具体的なさまざまな装置等に適用したものを説明する。この場合、必ずしも実施形態1で例示した薄板状の放熱部材1で形成するわけではなく、所望の形状(放熱フィン等)・材質(アルミニウム等)で形設された基材11に、実施形態1で例示したトルマリン層12を形成させたり、基材自体にショールトルマリン粉末を混入させて構成する。
(Embodiment 2)
Next, what applied the heat radiating member 1 to various various apparatuses etc. is demonstrated. In this case, the thin plate-like heat radiating member 1 illustrated in the first embodiment is not necessarily formed, but the base material 11 formed in a desired shape (heat radiating fin or the like) / material (aluminum or the like) is formed on the first embodiment. The tourmaline layer 12 exemplified in (1) is formed, or shawl tourmaline powder is mixed into the substrate itself.

まず、冷蔵庫の熱交換機系に用いて構成した例を、図3を参照しながら説明する。  First, the example comprised using for the heat exchanger system of a refrigerator is demonstrated, referring FIG.

冷蔵庫の熱交換機系Eは、図3に示すように、コンプレッサe1、冷媒タンクe2、被冷却室e3、熱発散機能部e4、それらを結ぶ管部材e5と、を備えて構成される周知構造のもので、それらの各構成体を、それぞれ所要形状に形設された基材11にトルマリン層12を形成させた放熱部材1で構成する。  As shown in FIG. 3, the heat exchanger system E of the refrigerator has a known structure that includes a compressor e 1, a refrigerant tank e 2, a cooled room e 3, a heat dissipating function part e 4, and a pipe member e 5 that connects them. Therefore, each of these components is constituted by a heat radiating member 1 in which a tourmaline layer 12 is formed on a base material 11 formed in a required shape.

このように放熱部材1を用いて構成された冷蔵庫は、放熱効果の向上によって熱交換率が向上して、極めて好適な冷蔵庫となる。  Thus, the refrigerator comprised using the heat radiating member 1 improves a heat exchange rate by the improvement of the heat dissipation effect, and becomes a very suitable refrigerator.

次に、放熱部材1をコンピュータFの所要箇所に用いて構成した例を、図4を参照しながら説明する。  Next, an example in which the heat dissipating member 1 is configured as a required portion of the computer F will be described with reference to FIG.

通常のコンピュータFの内部は、ケース(筐体)f1及びシャーシf2そして各機器f3の間においてはメッキ等が施されているか、金属素材そのものが露出している。しかしながら、この状態であると、内部で発生した熱がそれぞれの部材間で反射を繰り返し、外部へ熱を逃がしにくい構造、いわゆる魔法瓶状態に近いものになっている。  The inside of the normal computer F is plated between the case (housing) f1, the chassis f2, and each device f3, or the metal material itself is exposed. However, in this state, the heat generated inside is repeatedly reflected between the respective members, and the structure is difficult to escape the heat to the outside, that is, a so-called thermos state.

そこで、ケース(筐体)f1、シャーシf2、HDDやDVD等の各機器f3、CPUf4等の各構成体を、トルマリン層12を有した放熱部材1で構成することにより、内部熱反射を防ぐとともに、内部の熱を消耗させることにより、コンピュータFの内部温度を低下することができる。  Therefore, by constituting each structural body such as the case (housing) f1, the chassis f2, each device f3 such as HDD and DVD, and the CPU f4 with the heat radiating member 1 having the tourmaline layer 12, internal heat reflection is prevented. By exhausting the internal heat, the internal temperature of the computer F can be lowered.

ここで、2台の外付けハードディスク、(IO DATA機器製[HAD−iE160])を被試験体として放熱効果の実験をした。1台のケースはHDDノーマル(未処理)とし、もう1台のケースにトルマリン層を施した。このトルマリン層を形成するにあたり、粒径が概ね6μmのショールトルマリン粉末と、アクリル系の揮発性合成樹脂塗料からなる固定剤とを、その重量比1:1の割合で混和(塗布剤生成工程)して塗布剤を生成し、ショールトルマリンの1平方cm当たりの面密度が、0.05〜0.025g以内に収まるようにケースの全面に渡り塗って所定時間ごとに温度測定を行った。以下の実験結果を表12に示す。
Here, the heat radiation effect was tested using two external hard disks (IO DATA equipment [HAD-iE160]) as test objects. One case was HDD normal (untreated), and the other case was provided with a tourmaline layer. In forming this tourmaline layer, a shoal tourmaline powder having a particle size of approximately 6 μm and a fixing agent made of an acrylic volatile synthetic resin paint are mixed at a weight ratio of 1: 1 (coating agent generation step). Then, a coating agent was produced and applied over the entire surface of the case so that the surface density per square centimeter of the shoal tourmaline was within 0.05 to 0.025 g, and the temperature was measured every predetermined time. The following experimental results are shown in Table 12.

Figure 0004404855
Figure 0004404855

この実験によれば、HDDノーマルの60分後のケース平均温度は41.540℃、トルマリン層を設けたHDDは、40.060℃の計測結果が得られ、ケース温度が低下することが確認できた。  According to this experiment, the case average temperature after 60 minutes of HDD normal is 41.540 ° C., and the HDD with a tourmaline layer gives a measurement result of 40.060 ° C., confirming that the case temperature decreases. It was.

図4に示したコンピュータFは、ディスクトップパソコンであるが、図5に示したように、ノートパソコンGでも適用可能である。通常のノートパソコンケース(筐体)g1は、金属、またはポリカーボネート等の非金属による材質で構成されている。そのためケースg1を、ショールトルマリン粉末を混入させて構成することによって、内部熱を発散・消耗させ、ノートパソコンGの内部温度の上昇を防ぐことができる。  The computer F shown in FIG. 4 is a desktop personal computer, but it can also be applied to a notebook personal computer G as shown in FIG. A normal notebook computer case (housing) g1 is made of a metal or a non-metal material such as polycarbonate. Therefore, by forming the case g1 by mixing the shawl tourmaline powder, the internal heat can be dissipated and consumed, and an increase in the internal temperature of the notebook personal computer G can be prevented.

通常の各種部品等のシャーシ及び本体筐体部においては、メッキ等が施されているか、あるいは金属素材そのものが露出している。このような状態では、内部で発生した熱は外部へ逃げにくい。  The chassis and the main body housing part of various normal parts are plated or the like, or the metal material itself is exposed. In such a state, heat generated inside is difficult to escape to the outside.

この問題を解決するため、シャーシ等を放熱部材1で構成することで、内部熱放射を促進させるとともに、内部熱を消耗させることで、機器内部の温度上昇を防ぐことができる。  In order to solve this problem, by configuring the chassis or the like with the heat radiating member 1, the internal heat radiation can be promoted and the internal heat can be consumed to prevent the temperature inside the device from rising.

たとえば、図6に示すように、電動モータHのハウジング(筐体)h1を放熱部材1で構成してもよいものである。  For example, as shown in FIG. 6, the housing (housing) h <b> 1 of the electric motor H may be constituted by the heat radiating member 1.

また、放熱部材1で既存のノートパソコンNを載置させる支持台3を構成しても良いもので、この場合、図7に示したように、放熱部材1を、ノートパソコンNが載置するのに十分な幅と所要角度傾斜させるのに好適な高さでもって側面視略L字状に折り曲げ形成して支持台3を構成する。  Further, the support base 3 on which the existing notebook personal computer N is placed may be constituted by the heat radiating member 1, and in this case, the notebook personal computer N places the heat radiating member 1 as shown in FIG. The support base 3 is formed by being bent into a substantially L shape in a side view with a sufficient width and a height suitable for tilting at a required angle.

このように構成された支持台3にノートパソコンNを載置することで、ノートパソコンNのケース(筐体)n1に伝熱された熱が、さらに支持台3に伝わり、この支持台3から効率よく放熱される。したがって、既存のノートパソコンNに何ら手を加えることなく、放熱効果をさらに向上させることができる。  By placing the notebook computer N on the support base 3 configured in this way, the heat transferred to the case (casing) n1 of the notebook computer N is further transmitted to the support base 3, and from the support base 3 Heat is dissipated efficiently. Therefore, the heat dissipation effect can be further improved without any modification to the existing notebook computer N.

ここで、ノートパソコン単体と、トルマリン層のない支持台(銅板のみ)と、トルマリン層を形成させた支持台3(銅板+トルマリン層)との放熱効果を実験した。なお、トルマリン層は、粒径が概ね6μmのショールトルマリン粉末と、アクリル系の揮発性合成樹脂塗料からなる固定剤とを、その重量比1:1の割合で混和(塗布剤生成工程)して塗布剤を生成し、ショールトルマリンの1平方cm当たりの面密度が、略0.025gとなるように全面に渡り塗着して形成されている。また、温度センサーは、ノートパソコンの底面略中央に貼着させて温度計測している。その実験結果を表13に示す。
Here, the heat radiation effect of the notebook PC alone, a support base without a tourmaline layer (only a copper plate), and a support base 3 (copper plate + tourmaline layer) formed with a tourmaline layer was tested. The tourmaline layer is prepared by mixing a shoal tourmaline powder having a particle size of approximately 6 μm and a fixing agent made of an acrylic volatile synthetic resin paint at a weight ratio of 1: 1 (coating agent generation step). A coating agent is produced, and is formed by coating over the entire surface so that the surface density per square centimeter of shawl tourmaline is approximately 0.025 g. The temperature sensor measures the temperature by attaching it to the approximate center of the bottom of the notebook computer. The experimental results are shown in Table 13.

Figure 0004404855
Figure 0004404855

この実験結果から、トルマリン層を形成させた支持台3にノートパソコンを載置しただけで、効果的な放熱が可能になっている。  From this experimental result, it is possible to effectively dissipate heat only by placing the notebook computer on the support base 3 on which the tourmaline layer is formed.

このように、既存のものに対して、何ら手を加えることなく、放熱効果をさらに向上させる新たな構成体に放熱部材1を適用しても良いものである。  In this way, the heat radiating member 1 may be applied to a new structure that further improves the heat radiating effect without any modification to the existing one.

さらに、上述したパソコンの他に、放送機器、ビデオ、通信機器、ルーター、スイッチ、増幅器等、他の各種機器等へ適用できることは言うまでもない。また、液晶パネル発熱部、太陽電池受光部、各種トランス、電動モータ、冷却装置等放熱部、冷媒コンプレッサ、クーラー放熱部、車載ラジエータ、車両搭載部品等他の単体機器及び部品への適用も任意である。  Furthermore, it goes without saying that the present invention can be applied to other various devices such as broadcasting devices, videos, communication devices, routers, switches, amplifiers, etc. in addition to the personal computers described above. Also, application to other single devices and parts such as liquid crystal panel heat generating parts, solar cell light receiving parts, various transformers, electric motors, heat radiating parts such as cooling devices, refrigerant compressors, cooler heat radiating parts, in-vehicle radiators, vehicle mounted parts, etc. is optional. is there.

このように上述した実施形態は、本発明の好適な実施形態の一例を示すものであり、本発明はそれに限定されるものではなく、その要旨を逸脱しない範囲内において、種々変形実施が可能である。  Thus, the embodiment described above shows an example of a preferred embodiment of the present invention, and the present invention is not limited thereto, and various modifications can be made without departing from the scope of the invention. is there.

たとえば、トルマリン層は、上面や外界と接する面のみではなく、基材の両面に設けても良いもので、また、サンドイッチ構造となるように内部に設けても良い。基材の材質も特に限定されない。さらに形状は、薄板状、棒状、等、特に限定されるものではない。また、トルマリン層を彩色しても良い。  For example, the tourmaline layer may be provided not only on the upper surface and the surface in contact with the outside world but also on both surfaces of the base material, and may be provided inside so as to form a sandwich structure. The material of the substrate is not particularly limited. Further, the shape is not particularly limited, such as a thin plate shape or a rod shape. Further, the tourmaline layer may be colored.

本発明によれば、ショールトルマリン粉末と流動状の固定剤とを混和してなる塗布剤を、銅やアルミニウム等の熱伝導性の優れた金属からなる基材の表面に塗着して固化したトルマリン層を有して放熱部材を構成したことで、極めて安価に、かつ、容易に、製造できるにもかかわらず、従来の黒色塗装による放熱部材に比べ、大幅な放熱効果を得ることができる。 According to the present invention, a coating agent obtained by mixing a shawl tourmaline powder and a fluidized fixing agent is applied to the surface of a base material made of a metal having excellent thermal conductivity such as copper or aluminum and solidified. Although the heat dissipating member is configured with the tourmaline layer, a significant heat dissipating effect can be obtained as compared with the heat dissipating member using the conventional black coating, though it can be manufactured very inexpensively and easily.

かかる放熱部材を、放熱する必要のある機械(部品含む)、器具、電子部品、等、さまざまなものに対して適用することで、効率の向上、部品点数や構造の単純化などが期待できる。  By applying such a heat radiating member to a variety of machines (including parts), instruments, electronic parts, etc. that need to radiate heat, it is possible to expect improvement in efficiency, simplification of the number of parts and structure.

特に、冷却装置の熱交換機系に、かかる放熱部材を用いて構成することで、放熱効果の向上(熱交換の向上)によって冷却装置の温度が下がり、極めて好適な冷却装置が提供できる。  In particular, by using such a heat radiating member in the heat exchanger system of the cooling device, the temperature of the cooling device decreases due to the improvement of the heat dissipation effect (improvement of heat exchange), and an extremely suitable cooling device can be provided.
