The structure of the radiator radiator by the upper water, water chamber, radiator core, radiator cover, water discharge switch, etc.
A, the radiator cover is used to seal the water cooling system and adjust the working pressure of the system.
In general, the steam valve and air valve under the action of the spring are in the closed state. When the temperature of the radiator rises to produce steam,
so that the pressure rises to a certain value (generally 26 ~ 37KPa, some radiator cover can reach 0. LMPA), the steam valve is opened, and the steam is discharged from the steam discharge pipe.
When the water temperature drops, the vacuum degree generated in the cooling system reaches a certain value (generally 10 ~ 20kPa), the air valve is sucked open,
and the air enters the radiator from the steam discharge pipe.
