This thread took a turn for the absurd. Oil? Water? What a practical bunch of people. /s

They make resistors with adequate cooling... Almost as if they're rated for a certain number of watts of dissipation and you can buy them based on that. They are resistors after all. 

And if they overheat-- oh wait, they're heavy duty resistors, not ICs. Get a couple, put them in a metal project box, put it inline with the cable, and call it a day.

The dummy loads that I have worked with for medium wave and below and from 5 kilowatts down have all been convection air cooled. Broadband dummy loads that I have used for higher powers (up to 25 kilowatts) have been forced air cooled.
