Device for cooling synthetic yarns

The invention relates to a device for cooling synthetic yarns which are particularly twisted yarns in a deformation region. The cooling device comprises a rectangular radiator. The radiator is provided with a cooling groove used for guiding the yarns to open. The cooling groove is connected to a metering device used for supplying cooling liquid through a metering opening. Due to dynamic characteristics of yarns, a yarn inlet of the radiator comprises at least one ceramic insert in order to obtain uniform wetting and strong cooling. The ceramic insert forms a corrugated groove bottom in the cooling groove. Additionally, the yarns are guided in a contact manner on the surface of the ceramic insert. The metering opening is distributed to the ceramic insert. Therefore, cooling liquid is continuously provided for the yarns in a longer distance. 本发明涉及种用于合成丝线的冷却装置，所述合成丝线特别是变形区域中的捻线，所述冷却装置包括长形散热器，所述散热器具有用于引导所述丝线的敞口的冷却凹槽。所述冷却凹槽经由计量开口连接至用于供应冷却液体的计量装置。由于丝线的动力学特性，为了获得均匀的润湿和强烈的冷却，所述散热器在丝线入口处包括至少个陶瓷嵌件，所述陶瓷嵌件在所述冷却凹槽内形成波纹状凹槽
