摘　　要：针对金属材料散热器成本高、质量大、工艺复杂、制造过程污染环境等局限性,提出一种LED车灯用导热塑料散热器,采用有限元仿真与Minitab响应面优化相结合的方法,展开优化设计,为导热塑料散热器的结构优化提供了更加简便可靠的方法。研究表明,同样构型下塑料散热器的散热性能不如金属散热器,而结构优化后的导热塑料散热器与原始金属散热器散热性能相当,PCB铝基板最高温为73.53℃,仍在车灯正常使用范围内。因为传统观念的局限,国内很少有对车灯用导热塑料散热器的研究,因此本文将高导热工程塑料应用于LED车灯散热器是一项值得研究与发展的新领域,为未来导热塑料散热器的研究应用提供了参考意义,具有广阔的发展前景。Due to its high cost,large weight,complex technique and limits such as environmental pollution during the manufacturing process for the metal radiator,this paper proposes a LED plastic thermal conductive radiator for automobile headlight.It adopts the method of finite element simulation combined with Minitab response surface optimization to develop the optimized design.It provides a much simple and reliable method to optimize the structural design of the plastic thermal conductive radiator.Research shows that the heat dissipation performance of the plastic radiator in the same configuration is worse than that of the metal radiator,while the one with optimized structure has the similar performance to that of the metal radiator.The highest temperature of the PCB aluminum substrate is 73.53℃,which is still in the normal use range of the headlamp.Due to the limitation of traditional concepts,there are few researches on heat-conducting plastic radiators for car lamps in China.Therefore,the application of high-heat-conducting engineering plastics to LED car lamp radiators in this paper is a new field worthy of research and development,which provides reference significance for the future research and application of heat-conducting plastic radiators and has a broad development prospect.
