I read through all posts since 2010 containing "cowl flap".

Both Carlie and Matt mentioned butterfly cowl flap.

I understand it's hinged in the middle, but having a hard time visualizing it. When open, is the front then lowered into the outside air stream? If so, doesn't the rear part of the flap then block the opening from inside to outside of cowling?

If the front instead opens into the cowl (and rear down into the outside air stream), doesn't the front then block the air inside the cowling. Or maybe that's just a problem for me because my oil cooler goes all the way down to the bottom of the cowling ...

Any pictures?
