The invention discloses a heat dissipation assembly for a radiator, which comprises louver fins and a heat dissipation pipe A. The louver fins comprise flat and straight substrates and louver fins A. The flat and straight substrates are connected with the louver fins A. The heat dissipation pipe A is provided with an elliptical groove. The spindle parts are arranged at the two ends of the louver fin A, the appearance of the louver fin A better conforms to the aerodynamic law, the overall wind resistance of the radiator is greatly reduced, the spindle parts enable the near-wall area of the louver fin A to form a low-speed area, the heat exchange effect of air and the louver fin A is more sufficient, and the radiating efficiency is improved. Oval grooves are formed in the radiating pipes A, so that the turbulence degree of cooling liquid in the pipes is increased, and the Nusselt number of the radiating pipes is increased. Under the condition of the same heat dissipation requirement, due to the fact that the heat dissipation performance of the oval groove pipes is improved, the overall size of the automobile radiator can be reduced. The heat dissipation assembly is suitable for being used on the automobile radiator, and the heat dissipation effect of the radiator can be improved.

    本发明公开了一种用于散热器的散热组件,包括百叶窗翅片和散热管A,所述百叶窗翅片包括平直基片与百叶窗窗翅A,平直基片与百叶窗窗翅A连接,所述散热管A上设置椭圆形凹槽。百叶窗窗翅A在两端设置了纺锤部,百叶窗窗翅A外形更加符合空气动力学规律,散热器整体风阻大幅下降,且纺锤部使得百叶窗窗翅A近壁区域形成低速区,空气与百叶窗窗翅A的换热作用更加充分,提高了散热效率。散热管A在散热管上设置椭圆形凹槽,增加了管内冷却液的湍流程度,散热管的努塞尔数有所提高。在同等散热需求条件下,由于椭圆凹槽管散热性能的提升,能够减小汽车散热器的整体体积。本发明的散热组件适合在汽车散热器上使用,能够提高散热器的散热效果。
