METHOD FOR PRODUCING A DIRECT FLOW ALUMINIUM ABSORBER FOR A SOLAR THERMAL COLLECTOR AND A DIRECT FLOW ALUMINIUM ABSORBER AND A SOLAR THERMAL COLLECTOR

摘要

The application relates to a method (100) for producing a direct flow aluminium absorber of a solar thermal collector, the absorber comprising an absorber plate having at least one tube for a heat transport fluid, and at least one end tube for a heat transport fluid, the at least one end tube being connected to the absorber plate. The method com-prises laser welding (130) the at least one end tube to the absorber plate for producing the complete absorber to be coated by at least one layer configured to absorb light.
