Description
実施形態1について説明する。図1に示すように、本実施形態の熱交換器(10)は、冷凍サイクルを行う空調機(1)の冷媒回路(2)に設けられ、冷媒回路(2)を流れる冷媒を空気と熱交換させる。
図2及び図3に示すように、本実施形態の熱交換器(10)は、一対のヘッダ(16)と、多数の扁平管(20)(伝熱管)と、多数のフィン(30)とを備えている。ヘッダ(16)、扁平管(20)、及びフィン(30)は、何れもアルミニウム合金製の部材である。
ヘッダ(16)は、両端が閉塞された細長い中空円筒状に形成される。図2において、熱交換器(10)の両端には、一対のヘッダ(16)が起立した状態で配置されている。なお、扁平管(20)に対するヘッダ(16)の接合位置については後述する。
図3に示すように、扁平管(20)は、厚さよりも幅が長い扁平な形状の管である。扁平管(20)は、扁平管(20)の伸長方向と直交する断面が、角の丸い長方形状となっている。複数の扁平管(20)は、それぞれの幅方向に沿った側面が互いに向かい合う姿勢で配置されている。
フィン(30)は、概ね長方形板状に形成されたフィン本体(31)と、フィン本体(31)と一体に形成されたカラー部(32)とを備えている。フィン本体(31)には、扁平管(20)を差し込むための開口(33)が、複数形成されている。フィン本体(31)は、複数の開口(33)が並ぶ方向が長辺となっている。
図4に示すように、3列の扁平管(20)は、同じ長さに形成されている。3列のヘッダ(16)は、ヘッダ(16)の中心位置(O)が空気流通方向に一列に並ぶように配置されている。
本実施形態の熱交換器(10)は、空気流通方向に並ぶ複数列の扁平管(20)(伝熱管)と、複数列の扁平管(20)の一端部にそれぞれ接続された複数のヘッダ(16)とを備えている。そして、複数のヘッダ(16)のうち、空気流通方向の最上流側に配置される最上流ヘッダ(16a)は、空気流通方向において、最上流ヘッダ(16a)が接続された最上流扁平管(20a)の隣りの列の隣接扁平管(20b)から離れるように、最上流ヘッダ(16a)の中心位置(O)が最上流扁平管(20a)の中心位置よりも上流側にずれて配置されていること、及び/又は、複数のヘッダ(16)のうち、空気流通方向の最下流側に配置される最下流ヘッダ(16c)は、空気流通方向において、最下流ヘッダ(16c)が接続された最下流扁平管(20c)の隣りの列の隣接扁平管(20b)から離れるように、最下流ヘッダ(16c)の中心位置(O)が最下流扁平管(20c)の中心位置よりも下流側にずれて配置されているものである。
実施形態2について説明する。ここでは、本実施形態の熱交換器(10)について、実施形態1の熱交換器(10)と異なる点を説明する。
本実施形態の熱交換器(10)は、複数のヘッダ(16)は、扁平管(20)が伸びる方向にずれて配置されているものである。
