内燃机中的液体冷却装置及其制造方法
摘要：
本发明涉及一种内燃机(11)的液体冷却装置，并涉及生产该装置的方法。本发明的装置包括冷却回路(13)，所述冷却回路包括至少一个用于液体冷却剂的冷却通道(23、24、41)，该冷却通道与内燃机(11)的至少一个部件(12a、12b、31)热接触，冷却通道(23、24、41)的与冷却剂接触的壁在至少一部分区域内具有形成微结构的表面，所述形成微结构的表面具有一定多孔度和粗糙度。按照本发明，这种装置这样生产：建造用于液体冷却剂的冷却回路，该冷却回路具有冷却通道，所述冷却通道可以至少部分地与内燃机热接触；在冷却通道的与液体冷却剂接触的壁至少一部分上产生形成微结构的表面。
摘要（英）：

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.
