I was reading instructables today and saw a piece about making a ghetto AC from a Car Heat Core, pumping the Ice cold water thru it to a fan where it would pull all the air through the manifolds and creating a nice cold air.

I'm not much of a car guy, so I don't know if they are soldered or rather just one long piece of tubing.

If it is all one piece of copper or aluminum, I imagine there would be no lead solder the wort could come in contact with. If so, a new heat core might be neat to mess with since they're only about $27.

Figured I'd ask here in case anyone knew.

The one i replaced from a 300zx was copper tubing, however i didnt remove the cooling fins to see if it was one piece or multiple pieces soldered.

The vast majority of car heatercores are constructed of multiple thin copper tubes soldered to resivoirs at either end. They are pretty easy to identify:


However, a different style of heatercore that is generally not used (less efficient) consists of a single, long copper tube such as this:

I am fairly (like, 99%) certain that the 180* turns at the ends are soldred on though. Doesn't seem like it would be possible to assemble them otherwise.

EDIT: This is also why moonshine has such a bad reputation. They would use radiators assembled in the same fasion as the normal heatercores. Consequently, lots of lead, lots of death.

Thanks for cluing me in. I'll steer clear of using these. I wonder if you could find an RoHS-like compliant part that uses silver-bearing instead.

Someone used them as prechillers but not in direct contact with wort. Waste of time IMHO.

if they diddn't have lead you could use them in a cooler for a draught box... Any way to get them lead free?
