My 29 cents... I hadn't considered them to be A/C...
EVAPS because I saw no fittings so I was leaning towards specific model heater cores. Now that it was mentioned, they certainly do look like EVAPS.
They also seem to have pre-bent tubing for a specific vehicle and now that the fittings have been tossed, it would be difficult to re-use them as either kind of core. OH... and if they were an A/C evap, they would be able to stand about 150 pounds of pressure, and a heater core would only need to confine about 30 pounds. So, it would be OK for an evap core to be a heater core, but probably not the other way around.*
They would indeed make a great radiator for a Motorcycle or a Trans cooler or a Power Steering Pump cooler... for the do-it yourself-er.
Actual NEW models that are guaranteed sell for quite reasonable prices.
*So without going through all the hassle to sell them and not knowing if they have leaks and the pressures they will contain... I think recycling them as scrap would be your best bet as well.
Oh... definitely not for AIR or inter-cooling either... volume is not there...
HTH...
