Abstract: The present application provides a heat exchanger for exchanging heat between a first fluid and a second fluid. The heat exchanger may include a number of fin plates and a number of tubes extending though the fin plates with the first fluid therein. The fin plates may include a number of louvers extending between the tubes such that the second fluid flows through the louvers.

Abstract: The invention concerns a metal fin for heat exchanger with tubes, comprising means for increasing heat transfers consisting of diverting conformations (10,11) each arranged upstream and downstream of an aperture (3) when considering the direction (F) of air flow, to force the air to pass either side of said aperture, the upstream (10) and downstream (11) diverting conformations of two superimposed apertures (3) belonging to one same column extending along a determined length so that they substantially rejoin at the plane of extension (P) of offset apertures. (Figure to be published: FIG. 2).

Abstract: The invention relates to a heat exchange device including at least one heat exchange wall (6) between the refrigerant fluid (3) and the fluid to be cooled (4) having on one side a so-called hot surface (7) in contact with the fluid to be cooled, and at least one mechanical system (10) antagonist to the deposition on the hot surface of the exchange wall, of a solid layer of the fluid to be cooled. According to the invention, the means antagonist to the deposition is formed with a friction means (11) including a planar surface extending parallel to the hot surface of the exchange wall and having a heat conductivity such that the ratio of the heat conductivities of said friction means on the hot surface is larger than or equal to 3, and the mechanical system (10) includes means for supporting the friction means, adapted so that the latter rubs on the hot surface of the exchange wall via its planar surface.
