Hollow chamber profile made of metal, especially for heat exchangers

摘要

The invention relates to a hollow chamber profile made of metal, especially for heat exchangers. Said profile is made of an extruded base profile ( 10 ) having two broad parallel sides and two narrow sides or is made of a base profile which is a circular tube type or coaxial tube type. At least one channel ( 11 ) extends inside said base profile in the longitudinal direction thereof. The hollow profile has improved heat transfer properties on the sides and webs ( 13 ) which are deformed perpendicular to the longitudinal direction thereof.
