PERFORMANCE ANALYSIS OF HEAT DISSIPATION IN RADIATOR TUBE WITH NANO COATING

Radiators are a type of heat exchangers used to transfer thermal energy from one medium
to another for the purpose of cooling and heating. Upwards of 33% of energy generated by the
engine through combustion is lost in heat. Insufficient heat dissipation can result in the overheating
of engine, which leads to the breakdown of the lubricating oil, metal weakening of engine parts, and
significant wear between engine parts. To minimize the stress on the engine as a result of heat
generation, automotive radiators must be redesigned or material changing to be more compact while
still maintaining high level of heat transfer components. This is lead to the increased demand on the
power packed radiators, which can dissipate maximum amount of heat for any given space. This
project aims to do a comparison between ordinary radiator tube material and a new radiator tube
material with the nano coating. The existing material for the radiator tube such as aluminum alloy
and copper alloy is replace by brass material with nano coating material such as Al2O3.
