Replace copper with aluminium! ! !
Aluminium tubes are widely used in cooling applications. In these applications the heat transfer area is the tangential contact of tube to the surface which is very inefficient. In order to increase the heat tranfer rate we give D-form to the tubes. We produce serpantine as D-form in accordance with your application. To ensure the ease of soldering we weld copper connecter at the both ends of the serpentine.
We weld the copper connectors to the aluminium with eutechtic fluxless welding process.
