A sports car radiator has about that size and dumps 1 MW without boiling the coolant.

The question was about comparing the 1400KW of radiative cooling to how much convective coolig you could get from the same radiator on Earth.
A car's "radiator" doesn't actually lose heat by radiation though. It conducts heat to the air rushing through it. That's absolutely nothing like a radiator in a vacuum.
