2.3.4. Cooper Tube: This tube is fabricated of copper material, which has a high thermal conductivity reaches to 386 W/m.K, 104mm as a length, and 25mm, 20mm of external, internal diameter respectively, to assure the fusion of the material inside by increasing its temperature, thanks to heaters fixed on the lateral surface of the tube, to facilitate its transfer. a b
