Abstract
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.
Claims6
Hollow-chamber profile made of metal, especially for heat exchangers, consisting of an extruded base profile (10) with two parallel wide sides (16, 17) and two narrow sides (18, 19), where at least one channel (11) extends in the longitudinal direction of the base profile (10) through the interior space (23) in the base profile (10), wherein the narrow sides (18, 19) are shaped in the direction perpendicular to the longitudinal dimension of the base profile (10), where left-oriented profilings (21) transverse to the longitudinal dimension and right-oriented profilings (22) transverse to the longitudinal dimension alternate with each other along the two narrow sides (18, 19), and where the width (B) of the base profile (10) is the same over the entire length of the base profile (10), the narrow sides with the profilings have a uniform wall thickness along the entire length of the profile.
