In principle heat can be gotten rid of with radiators, like the EATCS[1] on the International Space Station. To maximize the heat radiated away, you'd need radiators with as much surface area as possible with an unobstructed view of the sky (no cloud cover). They'd also need to be as hot as possible, because thermal radiation power rises with the 4th power of absolute temperature There have been attempts to detect such thermal radiation from alien civilizations[2].

It should be detectable, but the Ĝ Infrared Search[1] didn't find any in the WISE[2] data. Jason Wright talked about this and related topics in a SETI institute video[3].

> About the only way you could detect such an event is to look at very distant galaxies for examples that had spherical chunk taken out of them. There have been actual studies searching for the waste heat of Dyson spheres[0]. You basically image an "empty" part of the sky in the visual spectrums and look for infrared waste. (The studies turned up nothing but were also limited in scope.) [0] - http://arxiv.org/abs/1408.1134
