HEATING BODY WITH COPPER WATER PIPE STRUCTURE WELDED TO ALUMINIUM SHEETS BY MEANS OF LASER BEAM BUNDLE

摘要

he invention relates to an indoor heating body composed of a copper water pipe structure welded to one or several aluminium sheets, via laser beam bundle concentrated to the acute angle formed between the copper pipes and the adjacent aluminium sheet. The water pipe structure has the form of a serpentine or meander and can be configurated before welding effected as above by laser beam bundle. The heating body in question can bear additional aluminium sheets, adequately shaped to increase heat exhaust.
