Abstract: An air flap for an air conditioning system of a motor vehicle may include a bearing section defining a pivot axis for mounting the air flap on a housing and at least one flap wing integrally formed on the bearing section. The at least one flap wing may extend from the pivot axis at least one of radially towards an outside and in a circumferential direction relative to the pivot axis at least in regions. At least one of the at least one flap wing and the bearing section may include an outer skin and at least one inner region delimited from the outer skin towards a respective inside. At least one of the at least one flap wing and the bearing section may be composed of a plastic. The plastic may be exclusively a foamed plastic in the at least one inner region.

Abstract: A heat exchanger for cooling a vehicle battery, in particular for hybrid or electric vehicles, having at least one fluid collector made of plastic, which is connected to at least one cooling element. In a heat exchanger in which the energy efficiency of the motor vehicle is increased, the cooling element is designed as a plastic tube, in which a fluid is conducted from the first fluid collector to a second fluid collector.
