Abstract A new type of metal-plastic composite heat radiator with hemispherical microstructure array was proposed in this paper. The influence of the
geometrical parameters of the microstructure array, including size of the hemisphere, configuration of hemisphere, tilt angle of the radiator, thermal
conductivity and radiation emissivity of the plastic, on the process of heat transfer under natural convection were numerically simulated. It was
concluded that the metal-plastic composite heat radiator with hemispherical microstructure array had comparable heat transfer behaviors with those
of metal heat radiator. So it is possible to replace metal heat radiator by such More >
