    • 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.
    • 本发明涉及一种内燃机(11)中的液体冷却装置及其制造方法。 根据本发明的装置包括冷却回路(13),其具有用于液体冷却剂的至少一个冷却管道(23,24,41),该管道与至少一个部件(12a,12b,31)热接触, 内燃机(11)。 与冷却剂接触的冷却管道(23,24,41)的壁在至少一个部分区域中包括具有一定孔隙率和粗糙度的微结构化表面。 根据本发明,该装置通过形成用于液体冷却剂的冷却回路来制造,该回路包括至少部分地与内燃机热接触的冷却管道,以及至少在至少 与液体冷却剂接触的冷却管道的一部分壁。
