Taking that design idea into this one. Requires less tubing.
The pumps and fans are solar powered.

Or you could have an open system where the heat exchange water gets exposed to the air.  Some of it evaporates and dumps heat to the air, and the cool water that falls to the bottom gets pumped through the heat exchanger.

No desiccant needed on this one.

Except this does not humidify the air like a swamp cooler does.

A swamp cooler with airflow powered by the sun ... looks like it should work.
You may have seen this guy's work.  He uses a desiccant.

Thought this might work.
Can you think if any improvements?
Might be reversible for heating too.
