Abstract
A tube body for a heat exchanger may include an outer structure composed of a band material. The outer structure may include two mutually opposite wide sides and two mutually opposite narrow sides delimiting an outer structure interior space. The tube body may further include an inner structure integrally arranged on the outer structure and composed of the band material. The inner structure may be arranged in the outer structure interior space and divide the outer structure interior space into at least two fluid ducts fluidically separated from one another through which a fluid is flowable. The band material may have a material thickness and, at least in certain portions, a material thickness of a portion of the band material defining the inner structure may be less than a material thickness of a portion of the band material defining the outer structure.
