The invention relates to the technical field of nano-materials for cooling and cooling, and provides a nano-powder for cooling and cooling. The powder is composed of small particles with different specific mass and particle size. The main components are SiO 2, Al2O3, ZnO, MgO, B2O 3, MnO, Li2O, ZrO, BN, and a small amount of Fe2O3, Na2O, SiC and Ti. The remainder is unavoidable impurities. The invention provides a heat dissipation and cooling nanometer powder with thermal radiation coefficient as high as 98%. The coating or ink produced with the nanometer powder as filler has obvious cooling effect. Compared with common paint or ink, the cooling range is increased by 5-25%. The cooling range varies with the structure of the coated object. Heat dissipation and cooling nanometer powder is a very good new material for producing heat dissipation coatings and radiation coatings.
