摘　　要：大功率光辐射二极管(light emitting diode,LED)散热技术已成为半导体照明产业发展的一项关键技术。设计了一种含热导管的LED散热器,分析了工作原理和结构特点。利用热电类比的方法对该散热器的热阻进行了详细的分析;并且推出了散热器总传热系数的方程式,最后通过实验测试了散热器各特征点的温度,验证了该散热结构设计的可行性与正确性。Heat dissipation technology of high power LED（ Light Emitting Diode）has become a key technology of semiconductor lighting industry development. A LED Radiator contains heat pipe was designed, and analyzed its operating principle and structural characteristic. The thermal resistance of this radiator was analyzed in detail by using the thermoelectricity analogy method, and also derived the formula of total heat transfer coefficient of radiator. At last, the radiator temperature of each feature point was tested by experiment, the feasibility and correctness of the heat dissipation structure design are proven.
