高速电主轴水冷系统固-液耦合传热仿真分析

摘要

The fluid flow and temperature distributions in the water cooling system of the electro-spindle were simulated by Fluent based on computational fluid dynamics and numerical heat transfer theory. Temperature rises under different initial temperatures of the cooling water and section sizes of the water channel were analyzed and compared. It provides a theoretical basis for reducing the electro-spindle temperature rise and optimizing design of the water cooling system.%依据计算流体力学与数值传热理论,利用Fluent软件对电主轴水冷系统中的流体流动和温度分布进行仿真,并对比分析不同冷却水初始温度、不同水道截面尺寸条件下的电主轴温升,为降低电主轴温升、优化水冷系统设计提供了一定的理论依据.
