True.
But that still leaves open their use in radiators (and that's basically the reverse of what a pre-cooler is)
I did not know until recently that F1 engines are built to much narrower tolerances than regular engines. The piston/engine block clearance is roughly 1/2-1/3 that of a regular car and if the block cools down the pistons cease.
So there are several fluids that need to be kept at the right temperature and REL can certainly help with this.
However the last time REL looked at this their tech was deemed "Too expensive" for F1.
Mfg Engineering work has cut REL HX mfg costs to about 1/10 of what they were.
