The intake process of the auxiliary kettle usually occurs when the internal pressure of the cooling system is reduced. When the engine is cooled, the cooling liquid accumulates and contracts to form negative pressure. At this time, the outside air enters the cooling system through the intake channel of the auxiliary kettle to maintain the pressure balance in the system. The exhaust process is on the contrary, when the engine is running, the temperature of the coolant rises, the volume expands, and the excess gas and coolant are discharged through the exhaust channel of the auxiliary kettle to avoid the internal pressure of the system is too high
Advantages
Maintain system pressure balance : the auxiliary kettle ensures that the internal pressure of the cooling system is kept within a reasonable range through the intake and exhaust process to avoid system failure caused by too high or too low pressure.
buffer and exhaust : when the engine is running, the auxiliary water bottle can effectively buffer the volume change of the coolant, and discharge the excess gas and liquid through the exhaust channel to ensure the normal operation of the cooling system.
