    Abstract: The invention relates to a liquid cooling device in an internal combustion engine (11) and to a process for manufacturing same. The device according to the invention comprises a cooling circuit (13) having at least one cooling duct (23, 24, 41) for a liquid coolant, the duct being in thermal contact with at least one component (12a, 12b, 31) of the internal combustion engine (11). A wall of the cooling duct (23, 24, 41) that comes into contact with the coolant comprises in at least one partial zone a microstructured surface with a certain porosity and roughness. According to the invention, this device is produced by forming a cooling circuit for a liquid coolant, the circuit comprising cooling ducts that can be brought at least in part into thermal contact with the internal combustion engine, and by generating a microstructured surface on at least part of the walls of the cooling ducts that come into contact with the liquid coolant.

    Abstract translation: 本发明涉及一种用于内燃发动机（11）和它们的制备的方法的液体冷却的装置。 本发明的装置包括具有用于液体冷却剂，其设置有所述内燃机的至少一个部件（12A，12B，31）（11）热接触的至少一个冷却通道（23,24,41），其特征在于一个冷却回路（13） 在局部区域具有与所述冷却通道（23,24,41）的至少一个微结构化表面具有一定的孔隙度和粗糙度的冷却剂壁接触一到来。 根据本发明，这样的装置由用于液体冷却剂形成的冷却回路，具有冷却通道。制造，其可以至少部分地与在热接触的内燃机用的至少一个上的液体冷却剂的一部分使进入接触壁 冷却通道产生一个微结构化表面。
