The invention relates to a cooling device (10), in particular a cooler assembly, for a motor vehicle (50) driven by an internal combustion engine or at least partially electrically driven, comprising: a first heat exchanger (12) which is or can be connected to a coolant circuit of the motor vehicle; a second heat exchanger (14) which is connected or can be connected to the refrigerant circuit of the motor vehicle; the first heat exchanger (12) is arranged upstream of the second heat exchanger (14) with respect to the main direction of the air flow (LS) through the cooling device (10), a first base surface (12a) of the first heat exchanger (12), which is subjected to the air flow (LS), being smaller than a second base surface (14a) of the second heat exchanger (14), which is subjected to the air flow (LS). It is provided that the first base surface (12a) is dimensioned such that the first base surface and the second base surface (14a) overlap only in an input-side region with reference to a refrigerant flow (14w) in the second heat exchanger (14). The invention also relates to an at least partially electrically driven motor vehicle having such a cooling device.
本发明涉及一种用于内燃机驱动或至少部分电动驱动的机动车(50)的冷却装置(10),特别是冷却器组件,所述冷却装置具有:第一热交换器(12),第一热交换器与机动车的冷却剂回路连接或能与机动车的冷却剂回路连接;第二热交换器(14),第二热交换器与机动车的制冷剂回路连接或能与机动车的制冷剂回路连接;以空气流(LS)穿过冷却装置(10)的主方向为基准,第一热交换器(12)布置在第二热交换器(14)上游,第一热交换器(12)的受到空气流(LS)加载的第一基面(12a)小于第二热交换器(14)的受到空气流(LS)加载的第二基面(14a)。在此规定,第一基面(12a)的尺寸被设定为使得第一基面与第二基面(14a)仅在以第二热交换器(14)中的制冷剂流(14w)为基准的输入侧区域中交叠。本发明还描述了一种具有这种冷却装置的至少部分电动驱动的机动车。
