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.
