A surface cooled heat exchanger that includes an extruded core member defining a plurality of spaced apart flow passages. The core member has first and second sides, one of said first and second sides defining a first set of flow openings communicating with the flow passages and one of said first and second sides defining a second set of flow openings communicating with the flow passages. A first unitary end cap connected to the first end of the core member has a first member sealing the first flow passage ends of at least some of the flow passages, and a second member extending from the first member partially over the side of the core member defining the first set of flow openings and defining at least one flow path between at least some of the first set of flow openings. A second unitary end cap connected to the second end of the core member has a first member sealing the second flow passage ends of at least some of the flow passages, and a second member extending from the first member partially over the side of the core member defining the second set of flow openings and defining with the core member at least one flow path between at least some of the second set of flow openings.
Il s'agit d'un échangeur de chaleur refroidi par ailettes qui comprend un noyau extrudé déterminant de multiples passages espacés. Le noyau comporte un premier et un second côtés, l'un de ces côtés définissant un premier groupe d'orifices de circulation communiquant avec les passages, et l'un de ces côtés déterminant un second groupe d'orifices de circulation communiquant avec les passages. Un premier embout unitaire raccordé à la première extrémité du noyau comprend un premier élément scellant les premières extrémités de certains des passages. Cet embout comprend aussi un second élément, allant du premier élément, partiellement du côté du noyau déterminant le premier groupe d'orifices de circulation et définissant au moins une première voie de passage, au moins entre l'un des premiers groupes d'orifices. Un second embout unitaire raccordé à la seconde extrémité du noyau comprend un premier élément scellant les secondes extrémités d'au moins certains passages. Cet embout comprend aussi un second élément, allant du premier élément, partiellement du côté du noyau déterminant le second groupe d'orifices de circulation et définissant avec le noyau, au moins une voie de passage, au moins entre l'un des seconds groupes d'orifices.
