Abstract: A heat exchanger arrangement is made available for heating an area of a vehicle which is to be heated, having: a first heat exchanger element for transmitting waste heat from at least one vehicle electrical component to be cooled to air, and a second heat exchanger element for transmitting heat from at least one vehicle heating device to air. The first heat exchanger element and the second heat exchanger element are arranged in such a way that air (L) to be heated is successively applied to them.

Abstract: The invention relates to a motor vehicle cooling system, comprising a first cooling circuit, in which a coolant can be circulated, at least one electrical component of the vehicle, which is integrated in the first cooling circuit and is to be cooled, wherein the electrical component can be cooled by means of a coolant that can be circulated in the first cooling circuit, a refrigeration system, which is designed to provide cooling capacity, and a refrigerant-coolant heat exchanger, which is designed to transfer the cooling capacity provided by the refrigeration system to the coolant. A first coolant-air heat exchanger for cooling air for a vehicle interior is arranged in the first cooling circuit.
