math + nobody likes…got that right! At least on my ends of it
I too agree those heat exchangers are an ass-ton of money for what is offered. No doubt. The expensive variants are made of copper, with pros/cons vs aluminum(application specific of course) in weight and thermal conductivity properties of the metals.
You hit it on the head with all four points. Those HE’s do use super thin cross sectional material with high density fin counts amongst other trade secret shit they probably have under wraps. Like you stated previously, higher fin density = lower overal airflow throughout the core design; thinner material cross section aids in aliviating some of that while not sacrificing surface area require for the cores overal function. You know all the details in regards to that area of discussion so we won’t carry on about it
Just a visual reference of external fin count for those still trolling this thread.
