Abstract
A metallic cooling fin for a motor vehicle heat exchanger has a central part having at least one set of fixed inclined lamellae, of selected form and spaced apart by apertures, the dimensions of which are predetermined to enable a fluid to pass between the lamellae. The lamellae in a common set are distributed in at least two groups, with the respective inclinations of the lamellae varying from one group to the other.
Claims15
A metallic cooling fin for a heat exchanger, the fin having a central part having at least one set of inclined fixed lamellae and apertures of select dimensions separating said lamellae from each other to enable a fluid to pass between the lamellae, wherein a set of lamellae comprises at least two groups, each group consisting of at least one lamella, each lamella defining an angle of inclination, respective angles of inclination of the lamellae in said set varying between said groups, each group having an order number, the value of the order number increasing with the magnitude of the angles of inclination of the lamellae in a respective group, the fin further defining a plurality of ranks of lamellae, the lamellae in a first rank and a last rank, in a set of lamellae, being part of a first group of lamellae having a lowest order number.
