 P: 132 A spiral heat exchanger is a countercurrent flow type heat exchanger. I should clarify for all readers I am not designing a heat exchanger. I am only trying to match current manufcaturing processes with this type of heat exchanger to produce a small cheap version. Spiral HEs currently are massive stainless steel vessels handwelded and used in chemical processing. They cost $10,000 and have flowrates of gallons per minute. I am looking to decrease the cost from$10,000 to \$10 and the size down from 5' diameter to 6". The quality also goes down but consumers don't need stainless steel for shower water etc. That's the dream.
