PURPOSE:To improve efficiency by opening an air discharge valve and removing the air in a condenser and increasing the heat-exchange area of the condenser when an air sensor under the condenser detects the presence of air and the coolant pressure becomes over a set positive pressure. CONSTITUTION:The lower part of a condenser 3 is connected to a reservoir 21 for storing the auxiliary coolant through an air discharge valve 24. when an air sensor 36 detects the state where the inside of the condenser 3 is full of air, and the pressure in the coolant circulation system is positive pressure, an air discharge valve 24 is opened, and the air in the condenser 3 is discharged into the reservoir 21 by the pressure difference. When the heat radiation area of the condenser 3 increases, and the heat radiation efficiency is restored, the control precision of the cooling apparatus can be improved, ad the pressure in the system and the coolant temperature are lowered, and the over-heat of the engine can be prevented. |
