Design and simulation analysis of a new type of micro metal-plastic heat radiator

摘要：

　　With the development of micro-nano machining technology (MNMT),micro heat radiator is getting attention.In this paper,the heat dissipation mechanism of light emitting diode (LED) ball lamp is introduced.And the LED heat radiator is simplified.On the basis of that,a new type of micro metal-plastic heat radiator of LED is put forward.And the LED heat radiator is simplified.A series of numerical simulations are carried out to compare the heat dissipation performance of micro heat radiator respectively made by metal,plastic,metal-plastic composite by the FloEFD software.Micro metal-plastic heat radiator structures,including fin spacing,fin thickness,fin height and substrate thickness,are carry out to be simulated.
