Description
従来のマルチシャンク型ヒーターの断面図を図1に示す。各U字ピース(線径:φ4mm、ピッチ16mm、シャンク高さ150mm)を、角度をつけずに(θ=0°)溶接して直線配列したマルチシャンク型ヒーターである。これを支持基体20に固定ピン30で取り付けた後、端子40を溶接した。このとき、横幅280mmの支持基体に対して横幅208mmのマルチシャンク型ヒーターを配置する場合、U字数は13個が上限であり、発熱部の展開長(総長)は2051mmであった。
実施例1のマルチシャンク型ヒーターの断面図を図2に示す。従来例と同様、横幅280mmの支持基体に対して横幅208mmのマルチシャンク型ヒーターを配置できるように各U字ピース(線径:φ4mm、ピッチ16mm、シャンク高さ150mm)を角度θ=±31.62°となるように傾けて溶接した。但し、ヒーターの左右両端の下向きU字のみ角度θ=±15.20°に変えて溶接した。この場合、U字数は15個となり、発熱部の展開長(総長)は2355mmであった。ヒーターの出力は発熱部の総長に比例するため、参考例と比べて15%程度の出力向上が見込まれる。
実施例2のマルチシャンク型ヒーターの断面図を図5に示す。従来例と同様、横幅280mmの支持基体に対して横幅208mmのマルチシャンク型ヒーターを配置できるように、各U字ピース(線径:φ4mm、ピッチ16mm)を角度θ=±31°となるように傾け、また、中央に1箇所、角度をつけずに(θ=0°)水平配置した部分を設けて溶接した。この場合、実施例1と同様、U字数は15個となり、発熱部の展開長(総長)は2355mmであり、従来例と比べて15%程度の出力向上が見込まれる。
実施例3のマルチシャンク型ヒーターの断面図を図6に示す。従来例と同様、横幅280mmの支持基体に対して横幅208mmのマルチシャンク型ヒーターを配置できるように各U字ピース(線径:φ4mm、ピッチ16mm、シャンク高さ150mm)を角度θ=±29.93°となるように傾けて溶接した。この場合、実施例1と同様、U字数は15個となり、発熱部の展開長(総長)は2355mmであり、従来例と比べて15%程度の出力向上が見込まれる。なお、図6の上図に示すように、右側端子部が左側端子部よりも出っ張ることになるため、左右で異なる長さ端子を用意する必要がある。
実施例4のマルチシャンク型ヒーターの断面図を図2に示す。従来例と同様、横幅280mmの支持基体に対して横幅208mmのマルチシャンク型ヒーターを配置できるように各U字ピース(線径:φ4mm、ピッチ16mm、シャンク高さ150mm)を角度θ=±35.66°となるように傾けて溶接した。この場合、U字数は16個となり、発熱部の展開長(総長)は2516mmであり、従来例と比べて22.7%程度の出力向上が見込まれる。なお、右側の端子部の向きが上向きとなるため、場合によって断熱材への接触のおそれがあるが、これについては、必要に応じて、他の接触を回避する手段を用いることができる。
