they were, as I said, "black body radiators" which are not theoretically ideal black bodies, but still manage to radiate black body radiation.
- dannypgh 9y agoI think the term you're looking for is simply "radiator."
- tensor_rank_0 9y agoyes that is more parsimonious however in non-technical language the term "radiator" is associated with heat exchangers. if you put heat exchangers on the sides of your spacecraft they would function as radiators so I suppose it doesn't matter anyway, arguing semantics is a waste of time.
- pocketstar 9y agoa "radiator" is a heat exchanger and "radiator" is the industry standard term. these semantics are required for effective communication about technical topics.
