The radiator is a car cooling system. The radiator in the engine water cooling system consists of three parts: the water inlet chamber, the water outlet chamber, the main board and the radiator core. Antifreeze flows inside the radiator core, and air flows outside the radiator core. Hot antifreeze cools because it radiates heat to the air, and cold air warms because it accepts heat from the antifreeze, so radiators are heat exchangers.
Radiators are also used to store water and dissipate heat. An air steam valve is arranged on the automobile radiator cover, and the public air hole communicates with the atmosphere.
When the water temperature rises, the cooling water in the car radiator expands, causing the water vapor pressure to rise, and the steam valve is deflated; when the water temperature drops, the pressure drops, the air valve opens, and the outside air enters the heat dissipation through the shared air hole. radiator so that the pressure inside the radiator remains constant.
Attention should be paid to the role of the car radiator.
When in use, the public air hole should be kept unblocked and cannot be blocked or lost its function, otherwise it will affect the heat dissipation performance of the radiator and engine. The cooling water in the radiator is not pure water, but the assimilation of water, coolant and various special preservatives, also called antifreeze.
The content of coolant in these antifreezes is 30% to 50%, which advances the boiling point of the liquid. Under a certain working pressure, the allowable working temperature of automobile antifreeze can reach 120 degrees Celsius, which exceeds the boiling point of water and is not easy to evaporate.
What Does a Car Radiator Do – What Does a Radiator Cap Do?
The role of the radiator is to seal the water cooling system and adjust the working pressure of the system. When the engine is working, the temperature of the antifreeze gradually rises. Because the volume expansion of antifreeze will increase the pressure of the cooling system. When the pressure exceeds the predetermined value, the pressure valve opens, and a part of the antifreeze enters the compensation barrel through the overflow pipe to prevent the expansion of the antifreeze from cracking the radiator.
When the engine is stopped, the temperature of the antifreeze drops and the pressure in the cooling system drops accordingly. When the pressure drops below the atmospheric pressure and there is a vacuum, the vacuum valve opens, and part of the antifreeze in the compensation bucket flows back into the radiator, which can prevent the radiator from being crushed by the atmospheric pressure.
Car radiator – a brief introduction to the function
Its most direct function is “heat dissipation”, as the name suggests. Since the radiator and water tank are used as the radiator of the car, in terms of their material, the metal is not corrosion-resistant, and should avoid contact with corrosive solutions such as acid and alkali to avoid damage. When adding water to the car radiator, the water tank cover should be slowly opened, and the body of the small partners and other staff should be kept away from the water inlet as much as possible to avoid scalding by the high-pressure and high-temperature oil and gas ejected from the water inlet.
ATradiator radiators have great quitity. alt spray test bench: Salt spray corrosion is used to test the reliability of the tested samples to ensure that the products can meet a variety of harsh environments.Vibration test bench: Ensures that the product is Vibration resistant to high intensity Vibration of the vehicle or equipment during operation.
