Study on application of heat pipe radiator in high power LEDs for street lamp

• 摘要：

  Heat pipe radiator was experimental and numerical studied to solve the cooling problem of high power LEDs for street lamp. Firstly, the surface temperature of the lamp housing was measured by IR sensor then surface temperature of the heat pipe radiator was also measured. Experimental results show that the average temperature of the heat pipe radiator is about 38°C and the distribution is even. So heat pipe radiator is applicable for high power LED street lamp and is one of the methods for solving the heat dissipating problem. Secondly, a mathematical model was built to simulate the distribution characteristics of the flow and temperature fields. Simulation results agree well with the experimental results and therefore the model is proved to be reliable. The results also suggest that there are several disadvantages of the heat dissipation fins. Optimizing designs and methods are discussed and put forward finally.
