摘　　要：基于效能-传热单元方法建立了水冷微通道分离式热管的一维稳态热性能计算模型,在保持蒸发器截面积不变的前提下,以系统的制冷量、能效比和蒸发器单位质量铝材制冷量为指标,以蒸发器的扁管根数、扁管内高、空气流量及翅片间距为影响因素,开展正交试验设计及参数分析。通过优化设计,系统的制冷量、能效比和单位质量铝材制冷量分别提高了41.19%、390.93%~395.94%和28.54%。各因素对制冷量影响的主次顺序为:空气流量>扁管根数>翅片间距>扁管内高,对能效比影响的主次顺序为:翅片间距>空气流量>扁管根数>扁管内高,而对单位质量铝材制冷量影响的主次顺序为:空气流量>翅片间距>扁管根数>扁管内高。A one-dimensional steady-state thermal performance simulation model for water cooling micro-channel separated heat pipes was established based on the method of efficiency-number of transfer unit.Under the condition of fixed cross-sectional area of evaporator,optimization design and parameter analysis by orthogonal test were carried out.The impacts of number of flat tubes,internal height of flat tubes,air flow rate,and fin pitch of evaporator on the performance of system in terms of cooling capacity,energy efficiency ratio(EER)and cooling capacity per unit aluminum quality of evaporator were analyzed.Through optimization,the cooling capacity,EER,and cooling capacity per unit aluminum quality of the system are increased by 41.19%,390.93%~395.94%,and 28.54%,respectively.The ranking order of the effects parameters on the cooling capacity is:air flow rate>number of flat tubes>fin pitch>the internal height of flat tubes.The ranking order of EER is:fin pitch>air flow rate>number of flat tubes>the internal height of flat tubes.While that of cooling capacity per unit aluminum quality is:air flow rate>fin pitch>number of flat tubes>the internal height of flat tubes.
