In order to improve the manufacturing accuracy of NC machine tool, it is crucial to reducing the temperature rise of high-speed motorized spindle. The cooling effect and temperature distribution of water-cooling system are simulated and analyzed based on thermodynamics, heat transfer theory and computational fluid dynamics in this paper. The results show that the cooling system has fine cooling effect; the temperature of cooling liquid is changed from low to high and then to decrease, the highest temperature is at the roundabout of helical water channel and the reason for this phenomenon is found out. The results provide the theory basis for the structure optimization for water-cooling system. |
