在HL-2A装置上针对各个需要加热或冷却的系统专门设计了不同的水循环回路。其水循环系统主水管道主要分为上、下两层:上层分布在上盖板上面,主要有真空室、上偏滤器、上欧姆线圈等系统的主水管道:下层分布在大底板下面,主要有纵场线圈、垂直场线圈、下偏滤器、下欧姆线圈、多极场线圈及多极场补偿线圈等系统的主水管道。管道与装 In the HL-2A device for each need heating or cooling system designed specifically for different water circuit. The main water pipe of its water circulation system is mainly divided into upper and lower layers: the upper layer is distributed on the upper cover plate, and mainly includes the main water pipe of the vacuum chamber, the upper divertor, the upper ohm coil system, etc. The lower layer is distributed under the large bottom plate, There are vertical field coil, vertical field coil, the lower divertor, the next Ohm coil, multi-polar field coil and multi-polar field compensation coil system such as the main water pipe.
