G0600401 Experimental Study about Radiation Cooling Effect of New Electro-Magnetic Radiant Materials Based on Polar Crystal Metals

Abstract

Experiments have been carried out to examine the performance of radiation cooing by new radiation materials, which is produced by mixing the very fine polar crystal metals into the high efficiency heat radiation paints. This concept is caused by increase of the surface area due to the rough surface generated by nano-size polar crystal metals. The best choice of mixing ratio between polar crystal powder and the radiation paints is 33.3% in weight. The results obtained show that the radiation effect of new radiation materials developed in the study is superior to those of existent radiation paints such as high efficiency heat radiation paints.
