No? Passive systems don’t do anything to cool other than simply exist.
These systems use energy and are deliberately activated to influence how heat is transferred. That’s the difference of active vs passive.
Hmm that's interesting, how does this system use energy to move heat around then, if there are no moving parts? Not a rhetorical question, I'm genuinely curious about this system, would you have more info or links to share?
Edit: I just saw the link from @Acters above, that's pretty cool. I'm not sure if it qualifies as "no moving parts" given that "Inside AirJet® are tiny membranes that vibrate at ultrasonic frequency", but I'm not gonna be hung up on a technicality, as it does seem a nice technology.
