I was thinking maybe making it a "combo" cooling device. I like how compact you made the whole sump unit and maybe to increase the cooling capcity more by putting the peltier in contact with the outflow. So one of those iCA nanochiller or "ice probes"... they're small and can be controlled with a Neptune... not sure how much more effective it would be, but wanted to see if you have any experiemental info/data on it.

I ran one of those iceprobes for many years on my 30 gallon hex. It wasn't very effective, even on a 30 gallon system. I don't think it wouldn't make any significant difference to the performance of this idea.

You're basically taking about one of these:


Problem is it would really be impossible to integrate into an evaporative cooler since they work on completely different principals. Also the idea behind the EC is be cost effective and efficient. The device above would probably use about 1000-1600 Watts to be beneficial on my system, and costs about $1500 so...

I was thinking more just the device itself, so without all the bells and whistles... you can get them as cheap as $120 but not sure the specs on it... It wouldn't be adding to the evaporative properties, but in line... But given what Untamed said, it's probably not worth it...

one sugestion to increase efficency, is to use somthing other than egg crate to creat a multi teared spill over (same idea that they use in the big cooling towers for refinerys) I don't think you could add it to yours as it might take a different configuration for air flow. The problem I see in your design is the water flows to the bottom unrestricted and quickly so I do't think you'll get much more cooling out of it. I have been playing around with this for a while trying to come up with a set up that is quiet enough to be in the same room as the tank.

basicly you have the water spilling over the sides and they are kinda stepped but instead of 90 degree steps it is like little "v"s so it fills up them spills into the one below and so one.. then the air blows upward in the oposit direction to create a counter flow open loop type design to minimize the foot print.

I'll see what I can come up with for a pic. everything has been stuffed in dark corners and packed away sence I took down my big tank.

basicly you need to use a spary nozzel to put the water in at the top, then have a series of trays, to catch, fill up and over flow, while sucking air from the bottom to the top.. trick is being able to make it not leak haha.

I have been looking for something better to make the louvers, or make them my self but haven't found anything I am happy with yet.

Number one rule in engineering is keeping things as simple as possible, your design is starting to sound pretty complicated for what's required, but I'm still interested and would like to see pics or a diagram if possible.
