Ko_deZ,

As I recall, you said that your heat exchanger is made of aluminum. and that it is about 1 meter long and about 10 cm by 10 cm, and that it is counter-flow, is that correct?

I wanted to build an experimental version similar in construction to your, only from plastic (I know it will not be as good).

I easily can see how I would build the counter-flow, but I don't see how I would get the air flows into the counter-flow structure.

Could you post a photo of your HX core? I am drawing a blank here...

Thanks,
