the air flow through the engine bay may be good when the engine is running, as air enters and flows through the engine and components, and exits through the rear. this is fine, as long as the car is in motion, or even if stopped but with the engine running, the fan will take care of it.
but as soon as you stop the engine, as the air tends to go up when hot and there is no opening anywhere up, it just stops flowing (another drafting board engineering failure).
anyway, just check it, and even measure the temp. and if you left the hood down, that heat may damage components. any. particularly rubber or plastic. and seals. anything.
and even if you open the hood, if it is under the sun, it remains hot forever.
dont believe me, measure the temps.
perhaps a simple solution may be when you reach a destination, to open the hood until it cools off. and if the sun hits it, place something as a spacer and close the hood partially.
that is what i do, and it cools off dramatically.

i hope this helps.
