摘　　要：为降低机柜的散热负荷,减小散热系统的体积和质量,并且提高冷却系统的能量利用效率,提出利用微通道平行流换热器泵驱动两相回路热管系统方案,基于AMESim软件研究质量流量、换热器风量、环境温度、冷凝器结构参数对系统换热性能的影响。研究结果表明:制冷剂质量流量过大、换热器风量过大对系统制冷量无显著影响。室外温度是系统换热性能的重要影响因素,室外温度由10℃增加至35℃时,制冷量降低了57.9%。冷凝器流程布置和扁管排布需要考虑换热性能和流动阻力之间的平衡,平行流冷凝器为3流程,扁管数目为(12,12,10)时,系统运行性能最佳。In order to reduce the heat dissipation load of the cabinet,reduce the volume and mass of the cooling system,and improve the energy utilization efficiency of the cooling system,a micro-channel parallel flow heat exchanger pump to drive the two-phase loop heat pipe system was presented.Based on AMESim software,the influences of the mass flow rate,air volume of heat exchanger,ambient temperature and structural parameters of the condenser on the heat transfer performance of the system were studied.The results show that the refrigerant mass flow rate is too large and the air volume of the heat exchanger is too large,and the cooling capacity of the system is not significantly affected.The outdoor temperature is an important factor affecting the heat exchange performance of the system.When the outdoor temperature increases from 10℃to 35℃,the cooling capacity decreases by 57.9%.Therefore,condenser process layout and flat tube arrangement need to consider the balance between heat transfer performance and flow resistance.When the parallel flow condenser is 3 flows and the number of flat tubes is(12,12,10),the system operation performance is the best.
