Addendum! Found a better image for that Songuns missile assembly:
So you can see where the nitrogen cartridges have been replaced by injection cylinders. Why is the hose under it exposed and outside the housing like that? It freezes! Don't want ice inside do you?
The injection cylinders PROBABLY are electrically operated solenoids that open to let in a burst of nitrogen linked to a temperature sensor; when the IR seeker heads cool off too much and start looking at the forbidden target aka the sun they let in another burst. The system PROBABLY alternates cooling each missile in turn to prevent too much stress during training and extended operations on the system, IR seeker heads are finicky bits of tech.
