That's a subsystem with three major sections, a working fluid, and its own heat rejection requirements. A resistive heater contains two parts - a properly placed wire and a switch.
Cooling for active outdoor technology has extremely variable outside temperatures (basically anything from -20 to 60 °C, or more if you take direct sunshine into account) and a constant generation of heat to be taken away.
Like mobile base stations of course have AC units and some amateur astronomers use peltier cooled sensors, but I would hardly call these mass produced consumer items.
