  • Heat exchange device for a cold-producing machine
    Patent number: 7380403
    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.
