Engine inlet air cooling device and vehicle

The invention relates to the technical field of engine cooling, in particular to an engine air inlet cooling device and a vehicle. The first heat exchange assembly is connected with one end of the engine and one end of the water pump and used for reducing the air inlet temperature of the engine through cooling liquid in the first heat exchange assembly when the air inlet temperature of the engine is larger than the preset temperature. And the second heat exchange assembly is connected with the first heat exchange assembly and the other end of the water pump and used for reducing the temperature of the cooling liquid which is output by the first heat exchange assembly and is subjected to heat absorption through cold air and returning the cooled cooling liquid to the first heat exchange assembly through the water pump. Therefore, the problem of how to efficiently utilize an existing cooling part for efficient cooling in a limited space is solved, and the air inlet temperature of the engine is efficiently contro
