摘　　要：采用计算流体力学方法对一种微槽平板热管散热器的翅片结构和尺寸进行优化设计,并对散热器的散热性能进行实验和数值模拟研究,平板热管散热器传热性能的数值计算和实验结果吻合良好。使用高度为50mm、间距为6. 5mm的错位开缝翅片能极大增强该平板热管散热器的散热能力。与纯铝合金散热器相比,使用平板热管作为散热器基底可使散热器的总热阻降低20. 6%。The experimental and numerical investigation on the thermal performance of a fiat heat pipe radiator with micro - grooves wick was conducted.The CFD method was employed to optimize the fins structure and size.It is found that simulation re- suits of thermal performance agree well with experimental data.The heat dissipation potential of the fiat heat pipe radiator is im- proved greatly by the misplace slot fins at spacing of 6.5ram and height of 50mm.The total thermal resistance of the heat radiator by the base of a flat heat pipe is reduced by 20.6% eompored with the aluminum alloy heat radiator.
