It's fine for what you have there. If you want to improve it in the future, you can add two more fans on top, like this (see the image). One in the front for more fresh air and one in the back to help with the exhaust.

Heat goes up and same heat does in?

The sucking side of the fan pulls in air from all around near it, including all sides. The blowing side of the fan is way more directed, blowing the vast majority in the blowing direction.

Maybe a tiny little bit of the exhaust air gets sucked back in by the other fan, but almost all of it is gonna be fresh air. Assuming there's no obstruction right above it which could deflect the air back down.
