| Abstract: | 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 has been proven. |
