Maybe early ships had a common practice of carrying large, cheap drop tanks of ice? The pics could have been "taken" just after dropping them but just before deploying radiators in their place. It could perhaps have been so very common that it wasn't mentioned much in the historical literature, just as a driver starting his car doesn't think much about the components of his car's internal combustion engine and radiator every time.
