顺排翅柱结构散热器在LED集渔灯上的应用研究

Research on Application of Sequential Finned Heat Sink to the LED Fish Aggregation Lamp

采用Fluent有限元分析软件进行模拟分析,研究了大功率LED集渔灯的顺排翅柱结构水冷散热器翅柱之间距与散热性能、均匀性的关系。在此基础上,提出了一种混合结构达到均匀性与散热性能兼顾的方案;同时研究了流速与散热器厚度的关系,以达到散热器的轻型化目的。

The relation between the finned columns distance with the heat transfer uniformity and performance of the water cooled heat sink for the high power LED lamp is analyzed by using Fluent ,a finite-element analysis software .On the basis of this ,a kind of hybrid bal-anced structure with good cooling performance is put forward ,and the heat sink thickness is optimized in order to decrease the weight of the heat sink .
