A cooling system and a vehicle. The cooling system includes: an inlet flow channel through which a cooling medium flows into the cooling system; an outlet flow channel through which the cooling medium flows out of the cooling system; a first set of cooling plates having a first inlet and a first outlet, the cooling medium flowing into the first set of cooling plates through the first inlet and out of the first set of cooling plates through the first outlet; a second set of cooling plates having a second inlet and a second outlet, the cooling medium flowing into the second set of cooling plates through the second inlet and out of the second set of cooling plates through the second outlet; and a distributor, via which the inlet flow channel is connected to each of the first inlet and the second inlet, and via which the outlet flow channel is connected to each of the first outlet and the second outlet.

The present disclosure provides a cooling device and a motor vehicle. The cooling device comprises: a cooling device housing with a cavity inside; a fluid inlet and a fluid outlet, which are arranged on the cooling device housing, a heat exchange fluid entering the cavity via the fluid inlet and flowing out via the fluid outlet; and at least two layers of flow disturbing parts arranged in the cavity. The present disclosure reduces a fin height of the flow disturbing part of each layer by providing at least two layers of flow disturbing parts inside the cavity, has a manufacturing process that is easy to implement, and has a low manufacturing cost; moreover, the flow disturbing part with the fin height reduced can be manufactured with a smaller fin pitch, such that the flow disturbing part has more fins, to increase a contact area between the flow disturbing part and the heat exchange fluid, effectively improving the heat dissipation/cooling efficiency of the cooling device. Compared with technical solutions in the prior art of a single layer of a flow disturbing part, at least two layers of flow disturbing parts may have a greater overall height, which may further increase the contact area between the heat exchange fluid and the flow disturbing part, improving the heat dissipation/cooling efficiency of the cooling device.
