To provide a multi-cooling device for a vehicle, which is capable of simultaneously cooling refrigerants for engine cooling, electric parts cooling, and a condenser, and also which is capable of satisfying reference cooling temperatures of the refrigerants.

The multi-cooling device for the vehicle is characterized in that one or more heat pipes are mounted to pass through two or more refrigerant passage pipes which go through with the same cooling system core unit. The refrigerant passage pipes include an engine refrigerant passage pipe, an electric part refrigerant passage pipe, and a condenser refrigerant passage pipe. In a pipe structure, the refrigerant passage pipes are sequentially stacked and arranged from top to bottom in a descending order of a refrigerant temperature, or any one of the refrigerant passage pipes is sequentially inserted into and arranged with any of the others so as to be multiplexed.
