Description
以下、図示実施形態により本発明を説明する。
図1は本発明の実施の形態1に係る空気調和機の室内側熱交換器を正面側から見た鉛直方向断面の部分拡大図、図2はその室外側熱交換器を正面側から見た鉛直方向断面の部分拡大図であり、いずれの図も隣り合う伝熱管の断面とその間のフィンを示している。
図3は本発明の実施の形態2に係る空気調和機の室内側熱交換器を側面側から見た鉛直方向断面の部分拡大図、図4はその室外側熱交換器を側面側から見た鉛直方向断面の部分拡大図であり、各図中、前述の実施形態1と同一部分には同一符号を付してある。
図5は本発明の実施の形態3に係る空気調和機の室内側熱交換器を側面側から見た鉛直方向断面の部分拡大図、図6はその室外側熱交換器を側面側から見た鉛直方向断面の部分拡大図であり、各図中、前述の実施形態1と同一部分には同一符号を付してある。
図7は本発明の実施の形態4に係る空気調和機の熱交換器の製作手順を示す正面側から見た鉛直方向断面の部分拡大図であり、図中、前述の実施形態1と同一部分には同一符号を付してある。なお、室内側熱交換器および室外側熱交換器は、いずれも同様の手順により製作されるため、ここでは室内側熱交換器を例に挙げて説明する。
前述の実施形態4においては、ヘアピン管の拡管のみによってフィン11とヘアピン管(伝熱管12D)とを接合しているが、拡管率を規定しなければ製品にばらつきが発生する。したがって、この実施の形態5では室内側熱交換器の伝熱管の拡管率を規定する。
前述の実施形態4においては、ヘアピン管の拡管のみによってフィン11とヘアピン管(伝熱管12D)とを接合しているが、拡管率を規定しなければ製品にばらつきが発生する。したがって、この実施の形態6では室外側熱交換器の伝熱管の拡管率を規定する。
