Abstract
又、熱交換器の製造工程で生産速度を速くしても、冷媒管の屈曲部が歪まないようにして、生産性を向上し得る熱交換器を提供する。
【解決手段】 熱交換のための冷媒が通過されるように複数回屈曲された各冷媒管10と、それら冷媒管10の外側壁面に配置されることで、前記各冷媒管10間を通過する空気との接触面積を拡張させる各冷却フィン12と、を含んで構成され、前記各冷媒管10は、断面楕円状に形成されて熱交換器を構成する。
【選択図】 図1
Description
図6は従来の冷凍装置に主に使用されるフィンチューブ型熱交換器を示した斜視図で、図示されたように、従来の熱交換器は、冷媒が通過しながら熱交換作用を行う各冷媒管102と、それら冷媒管102の外側壁面に所定間隔を有してそれぞれ拡大装着されて、熱伝逹性能を向上するために前記各冷媒管102間を通過する空気の接触面積を拡張させる複数の冷却フィン104と、前記各冷媒管102の両方側端に装着されて、それら各冷媒管102を支持する各支持ホルダー106と、を含んで構成されている。
又、前記冷媒管の屈曲部112の歪む現象は、生産速度が速くなるほど激しくなるため、生産性が低下するという不都合な点があった。
又、このような従来の熱交換器が冷凍装置に適用される場合、冷媒管を通過する冷媒の流動が円滑でないため、熱交換器の熱伝逹性能が低下することで、冷凍装置の冷却性能も急激に低下するという不都合な点があった。
又、熱交換器の製造工程における生産速度が速い場合にも、冷媒管の屈曲部の歪むことがないようにして、生産性を向上し得る熱交換器を提供することを目的とする。
又、前記冷媒管の長軸と短軸との長さ比は、1.4〜2.1:1であることを特徴とする。
又、熱交換器の製造工程における作業速度を速くしても、屈曲部の歪む現象を防止することで、生産性を向上し得るという効果がある。
図1は本発明に係る熱交換器を示した斜視図で、図示されたように、本発明に係る熱交換器は、冷媒が通過する各冷媒管10が所定間隔を有して配列され、前記各冷媒管10間には、それら冷媒管10間を通過する空気との接触面積を大きくして、熱伝逹性能を向上する各冷却フィン12がそれぞれ装着されて構成されている。又、前記各冷媒管10の両方側面には、熱交換器を支持するための支持ホルダー14がそれぞれ配置される。
即ち、前記冷媒管10の屈曲方向が長軸Pになり、冷媒管10の屈曲方向と直角をなす方向が短軸Qになるように形成されるが、このとき、前記冷媒管10の直線部18の長軸Pと短軸Qとの長さ比は、1.4〜2.1:1程度であることが好ましい。
又、前記冷媒管の直線部18は、断面直四角形状に形成することもできる。
又、相互対向する前記各冷媒管10間の横手方向の外側壁面に所定間隔を有して前記冷却フィン12がそれぞれ所定角傾斜して配列されることで、凝縮水の排出を円滑にすると共に、空気との接触をより円滑にさせる。
又、前記各支持ホルダー14には、前記各冷媒管10の屈曲部20が挿合される複数のスロット26が穿孔形成される。
まず、圧出成形機を利用して二つの冷媒管10と所定厚さを有する平板状の冷却フィン12形成部をそれぞれ圧出成形する。このとき、前記各冷媒管10は、断面楕円状に圧出成形する。次いで、噛合された二つのルーバリング(louvering)ギヤー間に冷却フィン12成形部をそれぞれ通過させると、前記各ルーバリングギヤーにより前記冷却フィン12成形部が所定間隔を有してパンチングされることで、各冷却フィン12がそれぞれ形成される。
次いで、冷媒管10の屈曲部20に形成された冷却フィン12を除去して、屈曲部20を支持ホルダー14のスロット26に挿合することで組立が終了される。
