PURPOSE:To prevent the thermal influence of an engine room by mounting a fan member capable of being moved according to the running speed of an automobile, at the rear side of a heat-exchanger and radiating the heat accumulated inside the engine room. CONSTITUTION:A motor fan 14 as a fan member is mounted at the rear side of a radiator 12 functioning as a heat-exchanger. The motor fan 14 may be turned by a moving mechanism 28 according to the running speed of an automobile. When the running speed is below the specified value, the motor fan 14 is sited near the rear face of the radiator 12 so that the radiator 12 is cooled with air supplied from a front grille and the air is then heated during the passing. When the running speed is over the specified value, the motor fan 14 is separated from the rear face of the radiator 12. A communication space 24 formed in such condition is communicated with a ventilation duct 22 via an opening part 26. So, the heat generated inside the engine room 10 may be radiated outside of the engine room. |
