Description
ところで、上述したような蒸発器のプレートフィンへの霜の付着量は、空気流れ方向の上流側、通常は下側で多くなり、空気流れ方向の下流側、通常は上側で少なくなる傾向を示す。しかしながら、特許文献1記載の蒸発器の除霜用パイプヒータの発熱量は全長にわたって一定であり、しかも除霜用パイプヒータの直管部の数は、プレートフィンへの着霜量の多い空気流れ方向上流側部分と着霜量の少ない空気流れ方向下流側部分とで均等になっているので、空気流れ方向上流側部分においてプレートフィンに付着した霜を短時間で除霜するには、除霜用パイプヒータ全体の発熱量を多くする必要があり、除霜用パイプヒータにおけるプレートフィンへの着霜量の少ない空気流れ方向下流側部分に配置された直管部および屈曲管部からの発熱量が余剰になって消費電力量が増加し、コストが高くなる。一方、除霜用パイプヒータからの発熱量を、空気流れ方向下流側部分において余剰にならないような量に設定すると、空気流れ方向上流側部分においてプレートフィンに付着した霜を融解するのに時間がかかり、やはり消費電力量が増加してコストが高くなる。
除霜用パイプヒータにおけるパイプの外周面の単位面積当たりの発熱量である発熱密度が、長さ方向の中間部分において両端寄り部分よりも高くなっており、除霜用パイプヒータのヒータ線がコイル状であり、発熱密度の高い部分のピッチが、低い部分のピッチよりも小さくなっており、除霜用パイプヒータの上端が蒸発器高さ方向の中間部に位置し、除霜用パイプヒータの前記中間部分が、蒸発器下端から1/3までの高さ部分に存在している蒸発器
2)除霜用パイプヒータの中間部分の一部が、最も風上側に位置する熱交換管の直管部よりも風上側に配置されている上記1)記載の蒸発器。

Claims (3)
- 並列状に配置された複数のプレートフィンと、プレートフィンに貫通状に取り付けられた複数の直管部および隣り合う2つの直管部を接続しかつ直管部より1つ少ない数の屈曲管部よりなる熱交換管と、プレートフィンに接触させられた複数の直管部および隣り合う2つの直管部を接続しかつ直管部より1つ少ない数の屈曲管部よりなる除霜用パイプヒータとを備えており、除霜用パイプヒータが、ヒータ線と、ヒータ線を収納するパイプと、ヒータ線の両端に接続された給電用リード線とを有し、空気が下から上に流れるようになっている蒸発器において、
除霜用パイプヒータにおけるパイプの外周面の単位面積当たりの発熱量である発熱密度が、長さ方向の中間部分において両端寄り部分よりも高くなっており、除霜用パイプヒータのヒータ線がコイル状であり、発熱密度の高い部分のピッチが、低い部分のピッチよりも小さくなっており、除霜用パイプヒータの上端が蒸発器高さ方向の中間部に位置し、除霜用パイプヒータの前記中間部分が、蒸発器下端から1/3までの高さ部分に存在している蒸発器。 - 除霜用パイプヒータの前記中間部分の一部が、最も風上側に位置する熱交換管の直管部よりも風上側に配置されている請求項1記載の蒸発器。
- 除霜用パイプヒータのヒータ線と給電用リード線とが、パイプの両端部内に配置されたコネクタによって接続されており、コネクタの周囲がシリコンゴムによって覆われている請求項1または2記載の蒸発器。
