Abstract

L'invention concerne un dispositif d'homogénéisation (18) de la distribution du fluide réfrigérant à l'intérieur de tubes d'un échangeur de chaleur. Le dispositif d'homogénéisation (18) comprend au moins un conduit (19) pourvu d'au moins une fenêtre (29) par laquelle le fluide réfrigérant est apte à entrer à l'intérieur du conduit (19) et au moins un orifice (22) par lequel le fluide réfrigérant est apte à sortir du conduit (19). Le conduit (19) offre au fluide réfrigérant une aire de passage. L'orifice (22) est d'un premier diamètre. Le conduit (19) loge au moins un organe de mixage (25) qui est d'une première longueur (L1) et d'un deuxième diamètre (D2). L'organe de mixage (25) comprend une pluralité d'éléments de mixage (30) identiques et répétés le long d'un axe d'allongement (A10), chaque élément de mixage (30) étant d'un pas (Pa). Un rapport de diamètre est défini par le rapport entre le deuxième diamètre (D2) et le premier diamètre, un rapport de mixage est défini par le rapport entre le deuxième diamètre (D2) et le pas (Pa), et un rapport de surface est défini par le rapport entre l'aire de passage et la première longueur (L1). Le rapport de surface est compris entre 0,02 et 1,38, le rapport de diamètre est compris entre 0,2 et 50 et/ou le rapport de mixage est compris entre 0,01 et 2,5.The invention relates to a device for homogenizing (18) the distribution of the refrigerant fluid inside tubes of a heat exchanger. The homogenizing device (18) comprises at least one duct (19) provided with at least one window (29) through which the refrigerant is able to enter the duct (19) and at least one orifice ( 22) by which the coolant is able to exit the conduit (19). The conduit (19) provides the refrigerant fluid a passage area. The orifice (22) is of a first diameter. The conduit (19) houses at least one mixing device (25) which is of a first length (L1) and a second diameter (D2). The mixing member (25) comprises a plurality of identical and repeated mixing elements (30) along an axis of elongation (A10), each mixing element (30) being one step (Pa) . A diameter ratio is defined by the ratio between the second diameter (D2) and the first diameter, a mixing ratio is defined by the ratio between the second diameter (D2) and the pitch (Pa), and a surface ratio is defined by the ratio between the passage area and the first length (L1). The surface ratio is between 0.02 and 1.38, the diameter ratio is between 0.2 and 50 and / or the mixing ratio is between 0.01 and 2.5.
