Title
(EN) A FILTER AND HEAT EXCHANGER DEVICE
(FR) DISPOSITIF COMPRENANT UN ECHANGEUR DE CHALEUR ET UN FILTRE
Abstract
(EN)
A filter and heat exchanger device comprises a substantially cylindrical housing (11) accommodating a tubular heat exchanger body (31) having fins (35) on the outer side thereof and an axial through passageway (32, 33) communicating with secondary-liquid inlet and outlet ports (19, 20). A heat exchanger compartment (26) inside a cylindrical partition (28) in the housing (11) accommodates the heat exchanger body (31) and a filter compartment (27) outside the partition accommodates a filter body (30). The two compartments (26, 27) communicate with one another and form successive sections of a primary-liquid flow path extending between primary-liquid inlet and outlet ports (17, 18). An elongate opening in the partition (28) is substantially coextensive with the heat exchanger body (31) and defines a flow passage (29) which interconnects the heat exchanger and filter compartments (26, 27). The heat exchanger body (31) is positioned in the heat exchanger compartment (26) and defines together with the inner side of the partition (28) circumferentially extending channels between the fins (35) of the heat exchanger body (31). An axially extending channel (36) formed in the cylindrical partition (28) diametrically opposite to the flow passage (29) is substantially coextensive with and open towards the heat exchanger body (31) and communicates with the primary-liquid outlet port (18).
(FR)
Ce dispositif comprenant un échangeur de chaleur et un filtre présente un carter sensiblement cylindrique (11), logeant un corps (31) d'échangeur de chaleur, tubulaire et doté d'ailettes (35) sur son côté extérieur, ainsi qu'un passage traversant et axial (32, 33) communiquant avec des orifices d'entrée et de sortie (19, 20) d'un second liquide. Un compartiment (26), destiné à l'échangeur de chaleur et situé à l'intérieur d'un séparateur cylindrique (28) placé dans le carter (11), loge le corps de l'échangeur de chaleur (31), et un compartiment (27) destiné au filtre et situé à l'extérieur de ce séparateur loge un corps de filtre (30). Les deux compartiments (26, 27) communiquent l'un avec l'autre et forment des sections successives d'un trajet d'écoulement d'un premier liquide, s'étendant entre les orifices d'entrée et de sortie (17, 18) de ce premier liquide. Une ouverture longitudinale, ménagée dans l'élément séparateur (28) s'entend sensiblement le long du corps de l'échangeur de chaleur (31) et elle délimite un passage d'écoulement (29) qui relie le compartiment de l'échangeur de chaleur et celui du filtre (26, 27). Le corps de l'échangeur de chaleur (31) est placé dans le compartiment correspondant (26) et il délimite avec le côté intérieur du séparateur (28) des canaux s'étendant de manière circonférentielle entre les ailettes (35) dudit corps (31). Un canal s'étendant axialement (36) et formé dans l'élément cylindrique (28) de manière diamétralement opposée au passage d'écoulement (29) s'étend sensiblement le long du corps (31) et est ouvert vers celui-ci et communique avec l'orifice de sortie (18) du premier liquide.
