前記第1の流体の循環通路を画定するように、互いに離れた2つの平行なプレートと、
前記プレートの間に垂直に配置された、フィンの少なくとも1つの第1の列およびフィンの少なくとも1つの第2の列であって、フィンの前記第1および第2の列は、長手方向に延在し、前記第1の列のフィンは、好ましくは、前記第2の列のフィンに対して互い違いの列に配置され、各フィンは、第1の縁部および第2の縁部によって長手方向に画定され、前記第1の縁部は、それぞれの端部に対応するプレートとの接続領域を含む、フィンの少なくとも1つの第1の列およびフィンの少なくとも1つの第2の列と、
を備え、
前記第1の縁部の前記接続領域は、前記プレートに垂直であり方向Xに平行な平面Pにおいて、プレートに対する法線Nに対してそれぞれ角度Aおよび角度Bだけ傾斜し、前記それぞれのフィンの前記第1の縁部および前記第2の縁部は、前記平面Pにおいて同一の輪郭を有することを特徴とする。
参照される特徴は、
−角度Aは角度Bに等しいことと、
−角度Aおよび/または角度Bは平面Pにおいて40°より大きく、好ましくは、45°以上であることと、
−平面Pにおいて、第1の縁部の長さの90%超が法線Nに対して傾斜しており、好ましくは、95%超であることと、
−前記第1の縁部は、法線Nに対して傾斜している少なくとも1つの直線部分および/または少なくとも1つの円形部分および/または少なくとも1つの楕円形部分を含むことと、
−前記第1の縁部は、法線Nに対して傾斜しており、かつ同一点に集まる方向を有する2つの直線部分を含むことと、
である。
図1及び図2には、長手方向Xに流れる第1の流体(例えば、高温排気ガス)と第2の流体(例えば、空気)との間の熱交換器1が示されている。
粉末160(この場合、金属)を収容する供給トレイ170と、
トレイ170からこの粉末160の上部を静かに移動させて、構造支持体180上にこの粉末160の第1の層110を広げる、ローラ130と、
を備える。
構造支持体180は、製造軸Zに沿って平行移動可能である(支持体180は、例えば、プレート、別の部品の一部、またはゲートとすることができる)。
レーザビーム195発生器190と、
所望の粉末部分160を溶融するように、このビーム195を構造支持体180の全体に向けることができるステアリングシステム150と、
