I just did a little quick model using some scrap 3/8" tubing and some solder I had here on my desk to do a mock up of a turbulator.

What I did was simply wrap the solder around the tube using approx. 1/4" spaces between each wrap and it looks like it would do a very adequate job of adding turbulence to the flow inside the rad.

I even cooked up a way to suspend it in the center.

Bend the ends of the wire to create a sort of spring that rests aganst the tube walls just past the end of the smaller diameter tube and shape it so that the spring when compressed inside the larger tube holds the smaller tube in the senter of the larger tube at each end.

I am definitely going to give this a try.

Now I just have to find 2 tubing sizes that when a wire is wrapped around it fit tightly together or at l;east as close as I can get. I am thinking perhaps 5/8" outer tubing and 3/8" inner tubing.

Or perhaps 3/4" and 1/2"

Dunno but this definitely gives me more to think about
