Description

Technical field The invention relates to a holding arrangement, in particular for a motor vehicle. State of the art Due to increasing charging capacities, thermal demands on a multitude of components, particularly in motor vehicles such as batteries, busbars, charging sockets, etc., are increasing. As a result of these increased charging capacities, the operating temperatures of these components can rise significantly. Description of the invention The object of the present invention is to provide a solution by which local overheating of a power line can be avoided particularly well. This problem is solved by the subject matter of the independent claim. Further possible embodiments of the invention are disclosed in the dependent claims, the description, and the figures. The invention relates to a holding arrangement, in particular a holding arrangement for a motor vehicle, in which at least one electrical conductor and at least one cooling line designed to carry a cooling fluid are held together by a holding element. This allows heat to be conducted from the electrical conductor to the cooling line by means of the holding element. Consequently, the electrical conductor can be cooled particularly effectively by the holding element through the conduction of heat and its transfer to the cooling line. The electrical conductor is in particular a high-voltage conductor. For example, the electrical conductor can be designed as a busbar. The holding element can be manufactured, for example, using a multi-component injection molding process, in particular a two-component injection molding process. For example, the holding element can comprise a rigid plastic part with an overmolded soft component, which can, for example, comprise rubber. The soft component can, for example, be a rubber lip. By means of this soft component, the electrical conductor could be particularly well fixed to the holding element. The holding arrangement thus comprises at least one power cable, at least one cooling line, and the holding element. The cooling line defines a cooling channel in which the cooling fluid can flow. In particular, the cooling fluid is a coolant such as water or oil. It is specifically provided that the holding element is formed in one piece. Furthermore, it is specifically provided that the holding element holds the at least one power cable in a central area arranged axially between the respective ends of the power cable, and thus not in an end area encompassing each end of the power cable. The axial direction runs in the longitudinal direction of the power cable. It is thus provided that the holding element holds the power cable not in its respective end areas, but outside the end areas in an intermediate area or the central area arranged between the end areas. Holding the at least one power cable and the at least one cooling line by means of the holding element makes it possible for the power cable and the cooling line to be held together, at least in certain areas, and thereby positioned together, particularly within the motor vehicle. The holding arrangement allows the at least one electrical conductor and the at least one cooling line to be routed together from a first vehicle component to a second vehicle component. The at least one electrical conductor can be cooled particularly effectively in the defined areas where the holding element rests against the conductor by transferring heat from the conductor to the holding element. It is possible to specify areas of the at least one electrical conductor to be cooled and to position the holding element against the conductor in one of these areas, thereby establishing a thermal connection between the conductor and the cooling line in this area. The holding element thus enables, firstly, the positioning of the at least one cooling line relative to the at least one electrical conductor, thereby at least locally holding the at least one cooling line against the at least one electrical conductor, and secondly, at least locally cooling the at least one electrical conductor by conducting heat away from the conductor to the cooling line via the holding element. In a possible further development of the invention, it is provided that the retaining element rests against at least one of the current conductors over a certain length, wherein the length of this length is at most 30 percent, and in particular at most 10 percent, of the total length of the current conductor. This means that the retaining element does not extend over a portion of the at least one current conductor in the longitudinal direction. The entire length of the power line is in contact with the power line, but only in the section where it is connected to at least one power line. This allows the retaining element to be made particularly small and lightweight. The retaining element also enables particularly effective local cooling of the power line in specific areas.
