Description
加熱可能な透明導電膜と、該透明導電膜に給電する複数のバスバーとを備える、電熱窓用板状体において、
前記複数のバスバーは、前記透明導電膜の左側縁部に接続される左バスバーと、前記透明導電膜の右側縁部に接続される右バスバーとを有し、
前記透明導電膜は、前記左バスバーから前記右バスバーまで連続的または切れ目のギャップが32mm以下で断続的に形成されるスリットによって複数の領域に区画され、
前記複数の領域は、第1の領域と、第2の領域とを含み、
前記第1の領域は、前記第2の領域よりも、前記左バスバーと前記右バスバーとの間の距離が小さく、且つ、前記スリットに対して垂直な方向における幅が小さく、
前記透明導電膜は、複数の前記スリットによって、3つ以上の領域に区画され、
前記透明導電膜は、前記スリットによって、所定周波数帯の垂直偏波の電磁波を透過させる周波数選択表面を形成しており、
前記所定周波数帯の中心周波数における空気中の波長をλ0とし、前記電熱窓用板状体の波長短縮率をkとし、前記電熱窓用板状体での波長をλg=λ0×kとして、
少なくとも1組の隣り合う前記スリットの間隔が、λg/4以下であることを特徴とする、電熱窓用板状体が提供される。
試験例1〜5では、透明導電膜を有する合わせガラスの透明導電膜に電圧を印加した時の温度分布を発熱シュミレーションによって解析した。試験例1〜4が実施例、試験例5が比較例である。
各ガラス板の厚さ:2.0mm
各ガラス板の熱伝導率:1.0W/(m・K)
各ガラス板の比熱:670J/(kg・K)
各ガラス板の質量密度:2.2g/cm3
透明導電膜の厚さ:0.002mm
透明導電膜の電気電導率:625000Ω−1・m−1
透明導電膜の熱伝導率:420W/(m・K)
透明導電膜の比熱:235J/(kg・K)
透明導電膜の質量密度:1.07g/cm3
合わせガラスの有限要素解析モデルは、アルテアエンジニアリング社製のソフトウェア(HyperMesh)を用いて作成した。このモデルのバスバー間に電圧を印加したときの温度分布は、汎用有限要素解析プログラムであるダッソー・システムズ社製のソフトウェア(Abaqus/Standard)を用いて求めた。
