## Main Question or Discussion Point

Are there any equasions out there which can calculate the heat dissipation of a water-cooled radiator with a fan on it? I would assume some of the variables would include:

-Volume of the radiator (240 x 199 x 45mm)=2149200mm^3

-Specific heat of water (

-Specific heat of the copper radiator fins (0.385 kJ/kgK)

-Rate at which air moves over the radiator fins (3.115 cubic meters/minute)

-Rate at which water moves through the fins (3.785 Liters/minute)

-Energy being dumped into the system (500 watt heat source)

Ultimately what I want to accomplish, is find out if said radiator can adequately radiate 500W of heat (ΔT of less than 40 degrees C

-Volume of the radiator (240 x 199 x 45mm)=2149200mm^3

-Specific heat of water (

*4.187 kJ/kgK)*-Specific heat of the copper radiator fins (0.385 kJ/kgK)

*-*ΔT between the temperature of the coolant (variable we are solving for), and the ambient air temperature (lets assume 20 degrees C)-Rate at which air moves over the radiator fins (3.115 cubic meters/minute)

-Rate at which water moves through the fins (3.785 Liters/minute)

-Energy being dumped into the system (500 watt heat source)

Ultimately what I want to accomplish, is find out if said radiator can adequately radiate 500W of heat (ΔT of less than 40 degrees C

*)*in an ideal environment. Is there some equasion into which I can plug these variables? Did I leave anything out?
