Collector Structure

1. Collector manifold.
2. Insulation.
3. Copper header pipe.
4. Stainless steel. mounting frame.
5. Evacuated tube.
6. Heat transfer fin & heat pipe.

Operation

Step 1. The sunlight strikes the dark-blue absorber inside the evacuated tube.

Step 2. The heat pipe transfers the heat up to the copper header pipe location in the insulated manifold box.

Step 3. A pump circulates water through the copper header pipe warming the water. In cold regions an anti-freze water mix is circulated through the collector to prevent freezing.

Step 4. The water or anti-freeze mix circulates back into the storage tank heating the fresh water inside the tank. If anti-freeze is used,a heat exchanger is also used.
