大流量增压回路在水循环冷却系统中的应用

摘要

This paper introduced the different pressured circuit in water recycling cooling system and the requirements to cool the large flow rate system.The clustered pressured circuit could be operated in closed circuit and cooled down by program.It could offer cooling water with the flow rate of 320 m3/h and pressured of 2.5 MPa.Parallel pressured circuit would offer the cooling water in two modes when it was under stable situation i.e.the mode with flow rate of 170 m3/h and pres-sured of 1.2 MPa and the mode with flow rate of 150 m3/h and pressured of 2.5 MPa.Adjusting the flow rate through the by-pass pipe would let the pressured circuit work in different cooling modes and satisfy the requirements of cooling water in different situations.Application of pres-sured circuit in cooling system would be reference for energy exchange between heat loads and offer experiences for following large flow rate cooling system design.%介绍了通过在水循环冷却系统中设计不同方式的增压回路，达到负载大流量冷却的要求。串联方式的增压回路可以闭合循环运行，按程序冷却，提供2.5 MPa、320 m3/h 的冷却循环水；并联方式的增压回路稳态运行时，可分别提供1.2 MPa、170 m3/h和2.5 MPa、150 m3/h的冷却水。通过旁路调节循环水流量，使增压回路可在不同冷却模式下运行，满足多种工况对冷却水的需求。增压回路在冷却系统中的应用可为处理发热负载的能量交换提供参考，为后续更大流量冷却系统的设计积累经验。
