Patent

CA 2471164

The invention relates to a device for exchanging heat, particularly for use in motor vehicle air-conditioning systems, comprising at least one coolant, at least one coolant inlet (3), and at least one coolant outlet (4), which lead into at least one head pipe (7, 8, 9), whereby the head pipe (7, 8, 9) is divided into at least one inlet section (41') and into at least one outlet section (42') by at least one separating element (49). The device for exchanging heat comprises at least one flow-through element (19), which has at least two flow paths situated at least partially parallel to one another, and at least one cross-distributor (10', 10'', 11', 11'', 12) via which the flow paths of the flow-through element (19) are fluid-connected so that the inlet section is fluid-connected to the outlet section of the head pipe (7, 8, 9).

L'invention concerne un dispositif d'échange de chaleur, notamment destiné à être utilisé dans des climatisations de véhicules, contenant au moins un agent réfrigérant, et comportant un orifice d'admission d'agent réfrigérant (3) et au moins un orifice d'évacuation d'agent réfrigérant (4) aboutissant dans au moins un tuyau de tête (7, 8, 9), ledit tuyau de tête (7, 8, 9) étant séparé par au moins un élément de séparation (46) en au moins une section d'admission (41') et au moins une section d'évacuation (42'). Ledit dispositif d'échange de chaleur comporte au moins un élément d'écoulement (19) présentant au moins deux trajets d'écoulement disposés de façon au moins partiellement parallèle l'un par rapport à l'autre, et au moins un embranchement transversal (10', 10'', 11', 11'', 12) reliant les trajets d'écoulement de l'élément d'écoulement (19) de manière que la section d'admission soit en communication fluidique avec la section d'évacuation du tuyau de tête (7, 8, 9).
