I know very little in this field but if anyone else does I would appreciate a little advice.
I'm doing a simple project just now, more out of curiosity and fun but if it works then it's a bonus. I'm converting an 8 litre coolbox from the measly 12V Peltier system to having my car a/c cool the box instead.
It's nothing fancy, just ducting from a rear vent into the box and an outlet hole which will also have a flap so I can seal it if using the box without any active cooling.
My question is to do with the outlet hole. I'll be making it on the opposite side of the inlet and it will be at the top so as for optimum airflow. But thinking thermodynamics, will there be an ideal size of outlet hole and is it related to the inlet? (60x60mm)
Thanks
