Title (EN) HEAT EXCHANGER CORE WITH END COVERS
(FR) NOYAU D"ECHANGEUR DE CHALEUR AVEC COUVERCLES EXTREMES
Abstract: front page image
(EN)The outermost tubes (50) of a heat exchanger core (20) have not been as adequately cooled as have the interior tubes (50) by the flow of air between the fins (40) and the tubes (50). Herein, a cover (80 or 85) is connected over the edges (45) of the fins (40) defining a respective one of first and second end surfaces (70, 75) and is spaced from the inlet surface (60) of the core (20). Consequently, the outermost tube (50), which is nearest the cover (80 or 85), is cooled substantially to the same degree as the other tubes (50). In one embodiment of the present invention, about a 5% increase in the thermal efficiency of the core (20) is attained.
(FR)Les tubes exterieurs (50) d"un noyau d"echangeur de chaleur (20) ne sont pas aussi bien refroidis que les tubes interieurs (50) par l"ecoulement d"air entre les ailettes (40) et les tubes (50). Un couvercle (80 ou 85) est relie sur les bords (45) des ailettes (40) definissant des premiere et seconde surfaces extremes respectives (70, 75), ce couvercle etant espace de la surface d"entree (60) du noyau (20). En consequence, le tube exterieur (50), qui est le plus pres du couvercle (80 ou 85), est refroidi sensiblement au meme degre que les autres tubes (50). Dans un mode de realisation, on obtient environ une augmentation de 5% du rendement thermique du noyau (20).
