Copper nano coated radiator for enhanced thermal efficiency

The present invention discloses a copper nano coated radiator for
enhanced thermal efficiency. The copper nano coated radiator comprises a radiator body comprising a plurality of heat exchange tubes and fins configured to transfer
heat from a working fluid to an окружа surrounding medium. The base substrate forming the heat exchange tubes and fins. The copper nano-coating layer uniformly
deposited on at least an outer surface of the heat exchange tubes and fins, wherein the copper nano-coating layer comprises copper nanoparticles having a nano-scale
dimension and is configured to increase surface area, thermal conductivity, and heat transfer efficiency of the radiator as compared to an uncoated radiator. The copper
nanoparticles have an average particle size in the range of 1 nm to 100 nm. The copper nano-coating layer is deposited by at least one of electrochemical deposition,
physical vapor deposition, chemical vapor deposition, thermal spraying, or sol–gel coating. The copper nano-coating layer has a thickness in the range of 50 nm to 10
micrometers
