【発明の詳細な説明】 生態学的熱電冷却機構 明細書の記載 本発明により開発された冷却機構は、市販で入手可能な半導体素子を用いるこ とを基礎にした完全に生態学的冷却装置(モジュール)の形成によって構成され たものである。このためには、発生される熱を最適化してガスを用いない冷却( 生態学的冷凍)の分野で近時は未だ既知でない水準にまで達する熱伝達機構を開 発しなければならなかった。 この分野に関する特許は他に幾つかある。 米国特許第3,137,141 号は熱電型水冷却装置を開示し、同装置は複数の横設貫 通孔を備えた支持壁と、金属ブロック内に鋳設された第1の水コイルを備えて該 コイルの一端を水源に接続し、他端を冷却水が放出される出口に接続した冷却部 材と、第2の金属ブロック内に鋳設された水コイルを備え、そのコイルの一端を 水源に接続し、他端を通路で加熱された水の出口に接続した放熱要素と、それら の間に設けられた熱電装置(モジュール)とを具備している。 2つの放熱要素は、熱電装置に対して両者間における熱架橋(サーマルブリッ ジ)を回避することが不可能なように配設される。 米国特許第3,450,572 号は、熱電々池を開示しており、この電池は2つの熱交 換器の間に固定され、同熱交換器は固定領域外に熱絶縁材層を間に挟持した2つ の対向面を有している。この米国特許に提案されている装置は最適な機械的剛性 を得る上では良好でなく、また2つの面の間で適正な熱絶縁を得て熱架橋を回避 する上でも良くない。 熱電装置は市販で入手可能な形式の熱電板と、2つの放熱器または放冷器とか ら成り、同熱電板の側面に好ましくはアルミニウム材から成る金属補充体が冷却 効果の発生に使用すべき側に付加されており、また、上記2つの放熱器は、その 一方を発熱側に、また他の一方を金属補充体の自由担持体側に付加して備えてい る。 この際に、問題となる表面同志の間(板と補充体、板と放冷器1、金属補充体 の自由端と放熱器2等の間)の接触性を完璧にすることが極めて重要である。こ のために、何らかの高導電体を用い、接触品質の向上を図り、それによって有害 な熱抵抗が生ずるのを回避することが望ましい。上記の高導電体としては高導電 性の硫酸シリコンまたは硫酸銅等がある。 冷却機構における他の重要な点としては、放熱器ないし放冷器、特に発熱側の 放熱器の設計に掛かっている。本願のモジュールないし装置に用いた設計は、市 販の放熱器に基づいて独自の設計を導入したものである。この際に導入した変更 は、可及的に熱抵抗(放熱器と大気との間の抵抗)を軽減して強制対流作用を活 性化することを狙った点である。このために、市販放熱器を機械加工してその基 部を4mmまで低減させ、またフィンの幅は2mmに低減した。そして後者、つ まりフィンを完全に直線化した。この結果、空気を前方の放熱器に向けて吹き出 す軸流ファンと共働させることで0.05°C/wの熱低値に低減させることが できた。このとき、空気は上述のように、市販入手可能な低姿勢のファンを用い 、前方に向けて吹き出させて最大限の乱流を得るようにしなければならない。 熱電モジュール(装置)の機械的剛性を確保するには何らかの形式の保持手段 が必要である。このような機械的剛性の向上は、冷却側と発熱側との間の熱架橋 の増加を来すことなく達成しなければならない。すなわち、例えば、金属ボルト やナットの使用により何らかの異常が発生した場合、結果的なロスは大きく(約 32%)になると言うことを念頭におかなければならない。このために、絶縁材 製の中間板を使用せねばならず、この中間板を介して各放熱器から金属杆を交互 配置でボルト締結しているのである。 この機構の応用例としては、図1に図示のような原型機構が開発された。この 原型機構は、液体タンク(例えば、水タンク)を備え、この液体タンクに3個ず つ2つのグループにした6つのモジュールを両側に固定し、冷凍側(2)を備え た放冷器(1)を同タンク内に残置させる。そして、金属補充体(8)を放熱器 (3)と熱電板の冷凍側(2)との間に配置する。発熱側4を有する放熱器(3 )は外側に置かれ、低姿勢軸流ファンの助勢を得て、強制対流式に作用するので ある。上述した各グループの3つの熱電モジュールに対して2つのファンが用い られ、空気流は小さなノズルによりファンの前方へ指向される。 各モジュールの機械的な剛性は、2つの放熱器を図2に図示するように結合す ることにより達成することができる。この図2において、絶縁材料(6)から成 る部分が設けられいることが理解でき、同時に金属杆(7)が相互に接触して熱 架橋を形成することなく、上記部分内に埋設されている。 同モジュールに対する電力の供給は、市販の直流動力源により確実に供給が成 される。最も信頼性のあるモデルでは、動力源を製造して全体的に機構内に格納 するようにもできる。 原型モデルの場合にはモジュールは60Wの板を装備して周囲温度30°Cの 時に次の温度を達成する。 周囲温度:30°C 冷却側温度= −10°C 温熱側温度= 33°C 水温 = −2°C もし飲料販売機(例えば、ビール販売機や清涼飲料販売機)の冷却コイルを本 機構内に配設すると、液体は適正温度に冷却される。 本機構は種々の利点を有するが、次の諸点を列記することができる。 ・冷媒ガスを使用することなく冷却することができる。 ・ファン以外の可動要素がない。 ・高性能である。 ・低電圧動力供給で済む。 ・機構が簡単でコンパクト化ができる。 ・適用性が広く簡単である。Detailed Description of the Invention Ecological thermoelectric cooling mechanism Description of description The cooling mechanism developed by the present invention uses a commercially available semiconductor element. Consists of the formation of a completely ecological cooling system (module) based on and It is a thing. To this end, the heat generated is optimized for gas-free cooling ( In the field of ecological refrigeration), a heat transfer mechanism reaching a level that is not yet known in recent years has been developed. I had to leave. There are several other patents in this area. U.S. Pat.No. 3,137,141 discloses a thermoelectric water cooling device, which has a plurality of horizontal A support wall having a through hole and a first water coil cast in a metal block are provided. A cooling unit with one end of the coil connected to a water source and the other end connected to an outlet through which cooling water is discharged. Material and a water coil cast in the second metal block, with one end of the coil Radiating elements connected to a water source, the other end of which is connected to the outlet of water heated in the passage, and And a thermoelectric device (module) provided between the two. The two heat dissipation elements are connected to the thermoelectric device by thermal bridges (thermal bridges). It is arranged in such a way that it is impossible to avoid U.S. Pat. No. 3,450,572 discloses a thermoelectric cell, which has two heat exchangers. It is fixed between two heat exchangers, and the heat exchanger has two heat insulating material layers sandwiched outside the fixed area. Have opposite surfaces. The device proposed in this US patent has optimum mechanical rigidity Is not good in obtaining heat insulation and avoids thermal cross-linking by obtaining proper heat insulation between two surfaces It's not good to do. A thermoelectric device consists of a commercially available thermoelectric plate and two radiators or coolers. And a metal replenisher, preferably made of aluminum material, is provided on the side surface of the thermoelectric plate for cooling. It is added to the side that should be used to generate the effect, and the above two radiators are One is provided on the heat generating side and the other is provided on the free carrier side of the metal replenisher. You. At this time, between the surfaces in question (plate and replenisher, plate and cooler 1, metal replenisher) It is extremely important to perfect the contact property between the free end of the heat sink 2 and the radiator 2. This Use some kind of high electric conductor to improve the contact quality and It is desirable to avoid the occurrence of significant thermal resistance. High conductivity as the above high conductor Silicon sulfate or copper sulfate. Another important point in the cooling mechanism is the radiator or cooler, especially on the heating side. It depends on the radiator design. The design used for the module or device of the present application is It is an original design based on the radiators on sale. Changes introduced at this time Reduces the thermal resistance (resistance between the radiator and the atmosphere) as much as possible to activate forced convection. This is the point aimed at becoming sexual. For this purpose, a commercial radiator is machined and its base The area was reduced to 4 mm and the fin width was reduced to 2 mm. And the latter one The Marifin has been completely straightened. As a result, air is blown out toward the radiator in front. It can be reduced to a low thermal value of 0.05 ° C / w by cooperating with an axial fan. did it. At this time, for the air, as described above, use a commercially available low-profile fan. , You have to blow it forward to get maximum turbulence. Some form of holding means to ensure the mechanical rigidity of the thermoelectric module (device) is necessary. This improvement in mechanical rigidity is due to the thermal bridge between the cooling side and the heat generating side. The increase must be achieved without coming. That is, for example, a metal bolt If any abnormality occurs due to the use of nuts or nuts, the resulting loss is large (approx. 32%) should be kept in mind. For this purpose, insulation It is necessary to use an intermediate plate made of metal, and alternate metal rods from each radiator through this intermediate plate. The bolts are fastened in the arrangement. As an application example of this mechanism, a prototype mechanism as shown in FIG. 1 has been developed. this The prototype mechanism is equipped with a liquid tank (for example, a water tank), in which three 6 modules in 2 groups, fixed on both sides, with freezing side (2) The cooler (1) is left in the same tank. The metal replenisher (8) is attached to the radiator. It is arranged between (3) and the freezing side (2) of the thermoelectric plate. Radiator (3 with heat generating side 4 ) Is placed on the outside and acts with forced convection because of the help of the low profile axial fan. is there. Two fans are used for the three thermoelectric modules of each group mentioned above And the airflow is directed towards the front of the fan by a small nozzle. The mechanical rigidity of each module connects the two radiators as shown in FIG. Can be achieved by In FIG. 2, the insulating material (6) is used. It can be understood that there is a part to be heated, and at the same time, the metal rods (7) come into contact with each other to generate heat. It is embedded in the above portion without forming a bridge. The power supply to this module is ensured by a commercially available DC power source. Is done. Most reliable models manufacture the power source and store it entirely within the mechanism You can also do it. In the case of the prototype model, the module is equipped with a 60W plate and the ambient temperature is 30 ° C. At times the following temperatures are achieved. Ambient temperature: 30 ° C Cooling side temperature = -10 ° C Temperature on warm side = 33 ° C Water temperature = -2 ° C If you have a cooling coil for your beverage vending machine (eg beer vending machine or soft drink vending machine) When placed in the mechanism, the liquid is cooled to the proper temperature. Although this mechanism has various advantages, the following points can be listed. -Can be cooled without using refrigerant gas. ・ There are no movable elements other than the fan. -High performance. ・ Low voltage power supply is enough. -The mechanism is simple and can be made compact. -Widely applicable and simple.
