Abstract: An extruded wing tube section (10) according to the invention consists of a formed tube portion (12) comprising at least one first wing section (20) integrally formed thereon in a first radial plane of the tube portion (12). The first wing section (20) has a plurality of first radial cut-outs such that a plurality of first wings (22) is provided in the first wing portion (20). Each of the first wings (20) is rotated about a radial axis of rotation such that each of the first wings (22) is rotated out of the first radial plane by a first angle 0°<?1<?° A first continuous transition portion is provided between the tube region (12) and each of the first wings (22), which transition portion has a twisted portion in the portion of the axis of rotation, and at least one expansion portion adjacent thereto.

Abstract: The thermoelectric heat pump comprises one or more thermoelectric modules having a hot side connected to a first heat exchanger and a cold side connected to a second heat exchanger, and is characterized in that it comprises a pair of elongated bar-like elements made of an electrically and thermally insulating material which are arranged at two parallel sides of the heat exchangers, at least partly interposed between facing flanges of said heat exchangers, at least one of said elongated bar-like elements including electric conductors for supplying power to the thermoelectric modules, as well as conductors for supplying control signals therefor, and that said heat exchangers contacting the thermoelectric modules are linked one another via a plurality of fasteners, each fastener being formed of a substantially C-shaped metal clip.
