DIY ventilation heat exchanger

Xringer · 06-23-10, 04:04 PM

I was thinking of using something like a hair-dryer or a weak heat gun
on the warm air input 'port' and a cool air fan on the 'heat-pick-up' port.

Maybe let the warmed-up air blow out on a strip of copper,
so the temperature can be easily measured with the IR Pistola.?.

I'll have to check my stock of 4mm coroplas and see if there is enough
available to make a small X-block exchanger.

Yeah, I have some left-over sheets of white, blue and yellow,
and two larger un-cut sheets of yellow, if it comes to that..

Yeah, it looks like I could use it all and make an 8x8x8 core..

Wow, I was just looking at the specs for the Airiva units and they are using a 12x12 core that's 11.25" tall..

It's 74 12x12 (4mm thick) sheets..

Maybe a little DIY 8x8x8 core could be used in a practical application after
testing is complete.. (If it has good heat transfer)..
