摘要
利用FLUENT软件对热电制冷不等间距的型材散热器进行了三维数值热流耦合模拟分析,得到了其流场及温度场分布,研究了在室温、强迫对流的条件下散热器尺寸、入口风速角度对其传热性能的影响,对散热器进行了结构尺寸选择,不仅使材料节省了22%,而且使散热器热阻降低了3.6%,为热电制冷冰箱用散热器的设计提供了有效的方法。
3-Dimentional and numerical simulation is done on the thermoelectric cooling and un- equal space between＇s plate fin heat sink by the FLUENT software ,and get the distribution of flow field and temperature field,on the condition of room temperature ,forced convection ,the influence on heat trans- fer performance brought by the size,angle of inlet air velocity is studied,and then made a choice about the heat sink,ont only the material decreased by 22% ,but also the heat resistant decreased by3.6% ,and an useful method is provided for the design of the heat sink used on the thermoelectric＇ cooling refrigeratory.
