摘　　要：对为解决高集成、高功率的通讯机柜的散热要求,设计了一种利用R22为工质,基于相变和自然循环散热技术,面向可热插拔通讯机柜的散热方案,并按照实际通讯机柜尺寸搭建了一套实验系统。通过模拟实际通讯模块的运行环境,进行了实验,结果表明:系统在没有额外驱动、冷却水温度在低于28℃的情况下,具备了3000W以上的散热能力,并能满足模拟电子设备的模块侧温度不超过65℃的要求。此外,非平衡热载荷的测试结果表明,非平衡载荷的启动、变化等情况不影响系统的稳定运行,说明该系统可以满足通讯模块载荷发生变化和热插拔等实际应用的需求。Based on the two phase natural convection,a system with R22 for the hot-swappable communication cabinet is built and tested for its heat dissipation capability.The result shows that this system can handle more than 3000W with the cooling water at about 28℃,meanwhile,it keeps the temperature of the electronic module to be lower than 65℃.Moreover,the tests of unbalance heat load start up and varying during operation are carried out to simulate cases of the heat load changing and hot swapping in a real cabinet.The result tells that the system operates stable with unbalance heat load and meets the requirement for hot swapping.
