Abstract: A heat exchanger assembly for a motor vehicle includes an inflow side, an outflow side, and at least one helically extending heat exchanger tube through which a heat exchanger fluid flows. A medium flows along a throughflow direction from the inflow side to the outflow side. A helix axis of a helix formed by the heat exchanger tube extends transversely with respect to the throughflow direction of the heat exchanger assembly.

Abstract: A heat exchanger assembly for a motor vehicle includes a heat exchanger formed by additive manufacturing. The heat exchanger includes two end tanks and a plurality of exchanger tubes. The plurality of exchanger tubes extend in a transverse direction relative to a longitudinal direction of the motor vehicle and connects the two end tanks to each other such that fluid is allowed to flow between the two end tanks by the plurality of exchanger tubes. The heat exchanger has a recess formed therein. A first exchanger tube of the plurality of exchanger tubes has at least one change of direction such that the first exchanger tube bypasses the recess at an angle to the transverse direction and runs along a side of the recess.

Abstract: A heat exchanger assembly for a motor vehicle includes a heat exchanger having at least one inlet tank, at least one outlet tank, and a plurality of exchanger tubes of an exchanger core. The exchanger tubes connect the inlet tank and the outlet tank and extend along a transverse axis that extends perpendicular to a longitudinal axis of the motor vehicle. Each exchanger tube defines a fluid passage path for fluid. A first pair of adjacent exchanger tubes form a first air passage path therebetween for ambient air and a second pair of adjacent exchanger tubes form a second air passage path therebetween for ambient air. The first air passage path has an air flow resistance that is different from an air flow resistance of the second air passage path.

Abstract: A motor vehicle undertray trim panel having an air inlet which is delimited toward the vehicle and the roadway by upper and lower flat elements, respectively, which extend arcuately rearward and upward in the direction of a vehicle components. The upper flat element runs, starting from a front end which lies in the vehicle longitudinal direction, in front of, adjacent to or behind an internal combustion engine of the motor vehicle and below a front radiator, first of all approximately horizontally and at a spacing below an oil sump of the internal combustion engine and then in a continuously steeper curve to its rear end which lies behind the oil sump and which is adjoined by a planar air ram plate which runs such that it is directed by a small amount substantially vertically upward, and then ends substantially freely in the engine compartment.
