Solar Heat Exchanger - Heat Transfer Tube

Step 2Bend the copper tube

With the copper tube full of sand or salt you may now bend the copper tube without fear of squishing the tube or deforming it to a point where a liquid cannot flow through it.

I used a 1" pipe to wrap the copper around. I am a pretty strong guy and this was a difficult task. In the future I may go with 1/4 inch tube rather than 3/8 inch diameter.

The reason I used fittings on the end was because I was not able to get the proper bend at the end of the copper tube. The turn was to tight to make without deforming the copper.

The copper coil you see in this photo will rest inside a 2" wide copper pipe.

I'll be adding more photos soon.
