Heat-radiant coatings and heat-radiant plate thereby

PURPOSE: A heat dissipation coating agent is provided to improve the emissivity of a heat dissipation plate and use the structure of an existing heat dissipation plate to dissipate heat by radiation as well as convection. CONSTITUTION: A heat dissipation coating agent includes infrared radiator powder and binder. The infrared radiator powder is one or a mixture of two or more selected from jade, sericite, cordierite, germanium, ferric oxide, muscovitum, manganese dioxide, silicon carbide, carbon, cupric oxide, cobalt oxide, nickel oxide, antimony peroxide, tin oxide, and chromium oxide. The binder is one selected from silane binder, organic binder, silicone compound binder, inorganic binder, organic and inorganic hybrid binder, and glass frit. The infrared radiator powder certainly includes silicon carbide and jade.
