The invention relates to a cooling device of a power cabin of a vehicle and particularly relates to a cooling component of a laminated type integrative power cabin of a special vehicle for military and police, which is used for cooling a coolant and clean air entering an engine. The problems of large occupying space of a vehicle body and complicated structure of the present arrangement mode are solved. The cooling component of the laminated type integrative power cabin of the special vehicle for the military and the police comprises a fan cowl, a water radiator, an intercooler and an air conditioning condenser, wherein the intercooler is arranged at the front part, the water radiator is arranged at the back part, the back part of the water radiator is provided with the fan cowl, the front part of the intercooler is provided with the air conditioning condenser, sealing strips are installed among the fan cowl, the water radiator, the intercooler and the air conditioning condenser, and an integral component is combined by a frame assembly of the radiator and an installing auxiliary component so as to form the cooling component. When the distance between the water radiator and the intercooler is 5mm and the distance between the intercooler and the air conditioning condenser is 12mm, the cooling effect is the best. The cooling component of the laminated type integrative power cabin of the special vehicle for the military and the police has small structural size, high heat-radiation efficiency and strong reliability.
