Abstract
内部に空洞部を有するコンテナと、前記空洞部に設けられたウィック構造体と、前記空洞部に封入された作動流体と、前記空洞部に350℃以下で水素を吸収し且つ350℃以下で水素を放出しない金属が設けられたヒートパイプ。
Description
対向する2枚のステンレス製板材で、内部空間である空洞部を有するコンテナを作製し、この空洞部にウィック構造体と350℃以下で水素を吸収し且つ350℃以下で水素を放出しない金属(水素吸収金属)を配置し、作動流体を封入した。ヒートパイプは、幅50mm×長さ100mm×厚さ0.4mm(空洞部の高さ0.2mm)の平面型とした。ウィック構造体としてステンレス製のメッシュを使用した。水素吸収金属としてチタン合金(幅4mm×長さ1mm×厚さ0.1mm)を1つ空洞部に仕込んだ。また、水素吸収金属の位置は、平面型ヒートパイプの長手方向における一方の端部となるようにし、ウィック構造体であるメッシュに挟んで固定した。なお、作動流体として水を使用した。図5に、実施例1の平面型ヒートパイプの具体的な構造を示す。
対向する2枚のステンレス製板材で、内部空間である空洞部を有するコンテナを作製し、この空洞部にウィック構造体と、実施例1と同質量の350℃以下で水素を吸収し且つ350℃以下で水素を放出しない金属(水素吸収金属)とを配置し、作動流体を封入した。ヒートパイプは、幅50mm×長さ100mm×厚さ0.4mm(空洞部の高さ0.2mm)の平面型とした。ウィック構造体としてステンレス製のメッシュを使用した。水素吸収金属としてチタン合金(幅2mm×長さ2mm×厚さ0.1mm)を1つ空洞部に仕込み、その5質量%が、コンテナのステンレス製板材と合金部を形成するように、2箇所、スポット溶接をした。従って、水素吸収金属はコンテナの内面にスポット溶接にて固定した。また、水素吸収金属の位置は、平面型ヒートパイプの長手方向における一方の端部とした。なお、作動流体として水を使用した。図6に、実施例2の平面型ヒートパイプの具体的な構造を示す。
実施例2のヒートパイプを電子線プローブマイクロアナライザー(EPMA)(日本電子社製:(型式)JXA-8800RL)で加速電圧15.0kV、照射電流5.018E-08A、分光結晶LDE1、TAP、PETH、LIFを用いて倍率1500倍で元素分析を行った。その結果、コンテナからは、Cr、Fe、Niが検出された。水素吸収金属であるチタン合金からは、Tiが検出された。スポット溶接の溶融痕からは、Ti、Cr、Fe、Niが検出された。溶接痕にはコンテナのFeとチタン合金のTiが検出されていることから、コンテナと水素吸収金属が溶融して一体となった合金部が形成されていることが確認できた。
水素吸収金属を設けなかったこと以外は、上記実施例1と同様の平面型ヒートパイプの構造とした。
(1)水素ガス発生量
作動温度100℃にて連続稼働させたときの水素ガス発生量を経過時間ごとに測定した。水素ガス発生量は、後述する表面温度(T1)における飽和水蒸気圧と後述する表面温度(T2)における飽和水蒸気圧の差から、水素ガスの分圧を算出し、表面温度(T2)を測定した部位から平面型ヒートパイプの長手方向における一方の端部の端面までの空間に水素ガスが溜まっていると仮定して水素ガスの体積を算出し、上記算出結果から理想気体の状態方程式を用いて水素ガス発生量(モル数)を特定した。
作動温度100℃にて連続稼働させたときのヒートパイプ内部の温度差を経過時間ごとに測定した。ヒートパイプ内部の温度差は、50℃の湯浴に、平面型ヒートパイプの長手方向における他方の端部から30%の部位までの領域を浸漬させ、この湯浴に浸漬している平面型ヒートパイプの部位のうち、その中心部の表面温度(T1)と、平面型ヒートパイプの長手方向における一方の端部から10%の部位(湯浴に浸漬していない)の表面温度(T2)との差(ΔT=T1−T2)から算出した。
水素ガス発生量の結果を図7に、ヒートパイプの温度差の結果を図8に、それぞれ、示す。図7(a)、(b)に示すように、水素吸収金属を空洞部に設けた実施例1、2では、それぞれ、連続稼働の時間が1000時間の水素ガス発生量が0時間の水素ガス発生量の約8倍、約1倍であり、稼働開始から1000時間経過しても水素ガスの発生を抑制できた。特に、図7(b)に示すように、水素吸収金属をコンテナの内面に溶接した実施例2では、連続稼働の時間が1000時間の水素ガス発生量は、0時間の水素ガス発生量と同等程度であり、稼働開始から1000時間経過しても水素ガスの発生をさらに抑えることができた。また、図7(a)、(c)から、稼働開始から1000時間経過した実施例1の水素発生量は、比較例の前記水素発生量の約1/3にとどめることができた。これに対し、図7(c)に示すように、水素吸収金属を空洞部に設けなかった比較例では、連続稼働の時間が1000時間の水素ガス発生量は、0時間の水素ガス発生量の約10倍であり、稼働時間の経過に応じて水素ガス発生量が増大した。従って、水素吸収金属を空洞部に設けることで、ヒートパイプの内部空間における水素ガスの存在量を低減することができた。
