Radiator Design

  1. Apr 28, 2010 #1
    When calculating the required area for a radiator using the equation

    Mass flow rate of air = Required Area x density of air x velocity of air

    Does the Required Area mean the Surface area on both sides of the radiator OR does it mean the total surface area of the cooling fins and tubes etc. ?

    The value that I acquired is 0.6387m^2 which seems to be substantially larger than I expected.

    thanks in advance

    Total area that comes in (effective) contact with the flowing air.

    You'd be surprised how small the 0.64m² finned radiator will end up being.
