Actually a chiller is a radiator.... Just that a chiller has external propulsion to enhance the thermal capacity and lower the operating temperature at which it still can opperate with a DT. A radiator is reliant on the temperature of the air being moved through it, for it's operational temperature. Both are, in principle exactly the same thing, they move heat from one substance, to another... In fact... all the heat transfer devices in a system work on exactly the same set of rules, they are all radiators or "heat transducers" as I like too call them....
