Abstract
Description
第1の熱膨張係数を有する第1の材料から作られ、その中に形成された少なくとも1つの流れチャンネルを有する第1の部分と、
前記第1の熱膨張係数と異なる第2の熱膨張係数を有する第2の材料から作られた第2の部分と、
を備え、
周囲温度の変化に応答して、流れチャンネル内に対応する変化を生じさせるために第1の部分と第2の部分を協働させるように、第1の部分と第2の部分を互いに関連させて配置し、それによって少なくとも1つの流れチャンネルの少なくとも1つのセクションの流れ抵抗を、少なくとも指定温度範囲内において少なくとも実質的に周囲温度から独立にする流れシステムを提供することによって達成される。
B=20μm
W=20μm
α=5×10-4K-1
ν=0.89×10-3パスカル秒
dν/dT=−0.0205×10-3パスカル秒K-1
これにより上記の式からD/d=26.5を得る。したがって、高分子チップが2mmの厚さを有する場合にはdが75.5μmによって与えられる。したがって追加のチャンネル5の深さは1.90mmになる。注意を要するが、上で行った計算においては、第1の部分2の蓋、言い替えると流れチャンネル4の上に位置する材料から生じる効果が省略されている。その種の効果を考慮に入れるためには、上記の計算における「d」が、蓋及び、流れチャンネル4と追加のチャンネル5の間に位置する第1の部分2の部分の有効な結合高さを表すと仮定すればよい。
