Definitions

  • the rough and / or porous microstructures of the device according to the invention can be distributed regularly or stochastically on the surface.
  • the preferred pore depth corresponds to a stochastic arrangement of the pores approximately the pore diameter. Particularly in the case of a mechanical incorporation of the pores into the surface, it is possible to move from round pore shapes to any desired geometric shapes, for example differently profiled longitudinal channels. The depth of the pores or of the channels or other depressions is thereby regardless of the pore width.
  • the layer thickness of the microstructured surface is preferably in the range of a few micrometers to a few millimeters, for example in the range of 1 to 10,000 microns, preferably in the range of 10 to 1000 microns.

Abstract

Dispositif de refroidissement de liquide d'un moteur à combustion interne (11) et procédé de fabrication dudit dispositif. Ce dispositif comporte un circuit de refroidissement (13) comprenant au moins un conduit de refroidissement (23, 24, 41) pour un liquide de refroidissement, qui se trouve en contact thermique avec au moins une structure (12a, 12b, 31) du moteur à combustion interne (11). Une paroi du conduit de refroidissement (23, 24, 41) se trouvant en contact avec le liquide de refroidissement possède au moins sur une partie une surface microstructurée présentant une certaine porosité et une certaine rugosité. Selon la présente invention, le procédé de fabrication d'un dispositif de ce type consiste à former un circuit de refroidissement pour un liquide de refroidissement, qui possède des conduits de refroidissement pouvant être mis au moins en partie en contact thermique avec le moteur à combustion interne, une surface microstructurée étant produite au moins sur une partie des parois des conduits de refroidissement venant en contact avec le liquide de refroidissement.
