AIR-GUIDING UNIT AND COOLING MODULE

An air-guiding unit is provided with a shroud (50) in which a vent hole (50b) is formed, an air-guiding duct (60), and a valve section (70) provided to the air-guiding duct. A heat radiator (20) of an air conditioning device, an engine-cooling heat exchanger (30) for cooling a travel engine (16), and an air blower (40) are secured to the shroud. Through an engine compartment opening (2) of an engine compartment (14), said opening (2) being open towards the front of the vehicle, the shroud guides air passing through the radiator and the engine-cooling heat exchanger. The air-guiding duct has a first opening (61) that is connected to the shroud through the vent hole and opens into the vent hole, and a second opening (62) that opens to the rear of the vehicle relative to the travel engine within the engine compartment. The air-guiding duct forms a duct interior channel (60a) for channeling air between the first opening and the second opening. The valve section increases and reduces the opening degree of the duct interior channel.
