Abstract
Description
冷却液が流通されるチューブと、前記チューブに取り付けられたフィンと、前記フィンに一体に設けられたルーバとを備える熱交換器であって、
少なくとも前記ルーバと前記フィンの接続部を、線膨張係数の異なる複数の金属による多層構造としたことを特徴とする熱交換器が提供される。
(1)ルーバ4とフィン3は、必ずしもその全体を多層構造とする必要はなく、少なくともルーバ4とフィン3の接続部を多層構造とすればよい。こうすることによりフィン3に対するルーバ4の傾斜角を冷却水温度に応じて可変とできるからである。従って当該接続部のみを多層構造とする変形例が当然に可能である。但し作製の手間を考慮すると全体を多層構造とする方が有利である。
(2)本実施形態では、初期位置のルーバ4の傾斜角をゼロとしたが、必ずしもそうする必要はなく、ゼロより若干大きい傾斜角としてもよい。この場合、フィン作製時において切り込み5の加工後にルーバ4がフィン3に対し若干折り曲げられる。
(3)切り込み5は、必ずしもコ字状もしくはU字状でなくてもよく、例えば一般のラジエータに見られるようなI字状であってもよい。
(4)本発明はラジエータ以外、例えばインタークーラ、オイルクーラ等にも適用可能である。従って冷却液はエンジン冷却水以外、例えばオイル等であってもよい。
