“…The heat dissipation of radiation is proportional to the radiation coefficient and the radiation area. The radiation coefficient of different materials is shown in Table 2 [5]. It is known that the heat dissipation performance of the radiator made by conductive plastics is better than that by the metal with the same structure.…”

With the development of micro-nanomachining 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.

“…Surface structures have been considered as an effective way to enhance heat transfer properties under natural convection [7,14]. Lee et al [15] used a conventional mechanical machine to fabricate micro-channels with hydraulic diameters ranging from 318 to 903 μm on copper, and indicated that the heat transfer coefficient was inverse proportional to channel size at a given flow rate.…”

Optimization for heat dissipation plays a significant role in energy saving and high-efficiency utilizing of integrated electronics. In this paper, we present a study of micro structuring on polymer-based flexible substrate coupled with aluminum-alloy heat sink. The heat dissipation performance was investigated by temperature evolution of a heat sink under natural convection by infrared (IR) camera, and results showed that the heat dissipation enhancement could be up to 25%. Moreover, the heat dissipation performance of a typical heat sink in terms of light-emitting diode (LED) hip was investigated via both thermal transient measurement and the finite element analysis (FEA). The maximum LED chip temperature of the laser-textured heat sink was approximately 22.4% lower than that of the as-received heat sink. We propose that these properties accompanied with the simplicity of fabrication make laser surface texturing a promising candidate for on-chip thermal management applications in electronics.

“…Test results are displayed in air pressure and coolant under the same pressure conditions, and the heat flow of polymer material microstructure heat exchanger can obtain cooling effect similar to the metal and ceramic. Bahadur and Bar-Cohen [12] and Han et al [13] studied the plastic radiator cooling effect. The results indicate that the plastic radiator can replace the metal radiator in certain situations.…”

A metal-plastic composite heat radiator with a hemispherical microstructure array was studied. A quantitative analysis was carried out for various factors that influence the radiator. The ratio of microstructure area, the heat generated by the heat source, the thermal conductivity of plastic, radiant emissivity of the plastic, the surface convection coefficient, and the environmental temperature were included in the analysis. The results suggested that we could achieve the exact influence size on the temperature of heat source.
