Abstract
Description
本発明は、熱交換における表面向上に関する。本発明は、より詳細には、超好熱性細菌で被覆された伝熱面を有する相変化熱交換器に関する。
相変化時の潜熱のため、沸騰は、沸騰伝熱に使用される熱交換器の表面から除去される増加した熱量に対応する。一般的に、沸騰伝熱を伴う高効率除熱システムを得るための方法を見つけることが求められている。この十年の間、製造、ナノテクノロジ及び表面処理技術の進歩は、(Li、C.ら、Nanostructured copper interfaces for enhanced boiling、small、2008、4(8)、1084〜1088ページにあるように)加熱面からの沸騰伝熱を増大させるミクロ/ナノ構造面に通じている。
本発明の主な目的は、上述した従来技術の欠点を克服することである。
本発明は、古細菌(Archaea)属から、さらにはスルフォロブス(Sulfolobus)属から、さらにはスルフォロブス・ソルファタリカス(Sulfolobus Solfataricus)種からとすることができる超好熱性細菌が与えられた伝熱面を有する熱交換器を提案する。熱交換器は、プール沸騰熱伝達に適合され得る。
次に、先に略述した図面を参照して、本発明は、好ましくは古細菌属から、より好ましくはスルフォロブス属から、さらにより好ましくはスルフォロブス・ソルファタリカス種からの超好熱性細菌が与えられた伝熱面を有する熱交換器を提案する。熱交換器は、プール沸騰熱伝達に適合されることが好ましい。
図1には、伝熱面からの除熱における被覆の性能を試験するための例示的なプール沸騰実験装置が概略化されている。装置は、プール沸騰を用いて冷却されるような高熱流束を必要とする伝熱面を有する熱交換器を模倣するように設計されている。
多数の気泡が表面から現れて離れていくことができる多数の活性核形成部位(11)をもたらすというバイオ被覆(biocoated)面の主な特徴が観察され、このことは、相変化熱の除去による流体への向上した伝熱に対応する。したがって、表面構造と活性核形成部位(11)の数が密接に関係することに従って、発明者らは、まず、スルフォロブス・ソルファタリカスコロニーの構造を、可視光又は蛍光により蛍光顕微鏡下で調査した。(活性核形成部位11に対応する)古細菌コロニーを、持続された最適条件下で取得し、次いで、培地のサンプルを、染色としてDAPI(4’,6−ジアミジノ−2−フェニルインドール)を用いて顕微鏡下で調査した。さらに、被覆面及び未被覆面のSEM(走査型電子顕微鏡)画像を取得した。SEM画像では、細菌で被覆された領域が区別可能に可視化され得る。
図2は、超好熱性細菌(ここでは、古細菌)被覆面及びベアシリコン面についての、壁部過熱(壁部温度と飽和温度との差)及び熱伝達係数が示されている。試験結果によると、細菌被覆面を用いた伝熱の向上は、未被覆面に対して20%高かった。
したがって、以下にある、
上述した従来技術の欠点を克服する、及び
加熱液体の沸騰での向上した除熱を可能にする伝熱面の提供
という目的は、本発明によって達成される。
10 加熱面
11 活性核形成部位
20 伝導体
30 容器
Q 所期の熱流方向
