| Abstract: | A new type of tube heat exchanger that could effectively utilize vertical convection and natural windflow is invited for high power LED.A parameterized model of this tube heat exchanger is developed for 100 W LED.Thermal design with Icepak software is performed for this tube heat exchanger.Calculation results indicate that the PN knot temperature is significantly affected by the diameter and thermal conductivity of heat tube aid speed of natural windflow.The PN knot temperature decreases with increasing the diameter and thermal conductivity of heat tube and speed of natural windflow.The PN knot temperature is not significantly affected by the surface calorific radiation and thermal conductivity of fins. |
