Abstract
【解決手段】熱交換器1Aは、間隔を置いて平行に配置された2本のヘッダパイプ2、3と、ヘッダパイプ2、3の間に複数配置され、内部に設けた冷媒通路5をヘッダパイプ2、3の内部に連通させた偏平チューブ4と、偏平チューブ4同士の間に配置されたコルゲートフィン6を備える。複数の偏平チューブ4の中で最も外側に位置する偏平チューブ4の、外側に向いた偏平面には、襞が鎧戸状に重なる形状の最外側コルゲートフィン6aが取り付けられる。
【選択図】図1
Description
襞を寝かせない場合、最外側コルゲートフィン6aの厚さは、最も薄い部分でコルゲートフィンの素材板1枚分の厚さしかない。襞を寝かせて重なり合わせることにより、素材板1枚分の厚さしかない箇所を極力減らすことができる。このようにしておけば、先端の尖った物体が最外側コルゲートフィン6aに横から接近しても、襞が重なり合った部分に接触する可能性が高くなる。そして襞が重なり合った部分に接触した、先端の尖った物体は、襞の重なりにより阻止され、最外側コルゲートフィン6aを突き抜けにくくなる。このため、従来最外側の偏平チューブ4を保護するために必要であったサイドプレートやサイドシートといった部品は必要でなくなり、部品コストを低減することができる。
1であっても構わない。
