Description
特に、エアコンからの空気を通風させるためのダクトでは、管状の発泡成形体を用いることにより、断熱性に優れ、軽量なダクトを実現することができる。さらに、こうしたダクトでは、製造時の発泡倍率を上げて発泡体内部の気泡を多くすることにより、断熱性、軽量さをさらに向上させることができるため、より効果的である。
本実施形態の発泡ダクトは、自動車用ダクトであり、エアコンユニットから供給される冷暖風を所望の部位へ流通させるための軽量な管状発泡成形体である。係る発泡ダクトは、例えば発泡剤を混合させた熱可塑性樹脂を分割金型で型締めし、ブロー成形することで成形される。
・引張破壊伸び:ブロー成形により得られた発泡ダクトの管本体を切り出し、−10℃で保管後に、JIS K−7113に準じて2号形試験片として引張速度を50mm/分で測定を行った値である。
・引張弾性率:ブロー成形により得られた発泡ダクトの管本体を切り出し、常温(23℃)で、JIS K−7113に準じて2号形試験片として引張速度を50mm/分で測定を行った値である。
本実施形態の発泡ダクトは、前記凹部11の形成に加えて、板状部分であるフランジ部8に堰き止め凹部を形成することで、異音の発生をさらに抑制するものである。なお、本実施形態の発泡ダクトにおいて、先の第1の実施形態と同一の部材については、第1の実施形態と同一の符号を付し、その説明は省略する。
