Product Description

1.Product Introduction
The role of the radiator transfers the heat absorbed by the coolant in the body to the outside air, and the temperature of the coolant is reduced.The structure of the radiator The radiator is composed of the upper water space, the lower water chamber, the radiator core, the radiator cover, the water drain switch, etc.The function of the aluminum radiator cap is to seal the water cooling system and regulate the working pressure of the system.
Under normal circumstances, both the steam valve and the air valve are closed under the action of a spring. When the temperature in the radiator rises to produce steam and the pressure rises to a certain value, the steam valve opens and water vapor is discharged from the steam discharge pipe. When the water temperature drops and the vacuum generated in the cooling system reaches a certain value, the air valve is sucked open, and the air enters the radiator from the steam exhaust pipe.
Compensation buckets Compensation buckets are also called liquid storage tanks, expansion tanks, and auxiliary water tanks. The compensation bucket is made of plastic and connected with the overflow pipe on the radiator and the coolant port with a hose. When the cooling liquid is heated and expanded, part of the cooling liquid flows into the compensation water bucket; when the cooling liquid is cooled, part of the cooling liquid is sucked back to the radiator, so the cooling liquid will not be lost.

3.Product Advantage And Application
The main function of the aluminum radiator cap is to release excess water or pressure when the cooling system expands due to the increase in temperature and pressure; it flows into the auxiliary tank, and when the temperature of the cooling system is low, the auxiliary tank is re-opened through the aluminum radiator cap. The water is sucked back into the cooling system, so that it can keep the water volume of the cooling system without water shortage when the temperature is high or low.
The other is that the aluminum radiator cap has a fixed pressure value. The water is not easy to boil under high pressure. It is easy to boil at low pressure. Boiling will produce air. Therefore, the  aluminum radiator cap can maintain a constant pressure in the system and use high pressure to make it boiling. Increase the heating efficiency, and the purpose of the radiator with pressure is to prevent the water from boiling, so that it can dissipate heat more effectively.
