Abstract

Abstract:

The calculated results for cooling electrode based on the previous design are presented. When the power is 9000W in glow discharge conditioning, the temperature of electrode cooled by water with speed of 4~6 m•s^-1 will not be over 100°C, and the temperature will not be over 200°C when the electrode is cooled by Helium with speed of 300m•s^-1. The calculation shows that cooling by water is more efficient than by Helium.

摘要：

对清洗放电时ITER 辉光放电电极采用水冷和气冷条件下的电极冷却进行了计算。当辉光放电清洗功率为9000W，冷却水的流速为4~6m•s^-1，入口温度为室温25°C时，电极的温升不会超100°C。当冷却媒介为氦(He)，速度为300m•s^-1，入口温度为室温25°C时，最高温度不会超过200°C。计算表明，当仅仅考虑因辉光放电电功率所导致电极发热时，水冷可以满足电极辉光放电时的冷却要求。
