What is a Car Radiator?

[JeffreyAnn]

Car radiator, also known as a heat exchanger or overflow tank, is a crucial component of water-cooled engines. It serves as the heat exchanger for water-cooled engines, maintaining the engine's normal operating temperature through air convection cooling. The radiator is an integral part of the automobile engine and the main component of the car's cooling system. Its function is to dissipate heat and maintain the engine's temperature. The working principle of the radiator: The coolant circulates through the engine's water passages, absorbing heat from the cylinder block, and then dissipates the heat through large-area cooling fins to maintain the engine's optimal operating temperature. The reason it's called a "water tank" is that older domestic trucks used to be filled with water. With technological advancements, modern cars have higher maintenance requirements, and coolant is now added to the radiator instead of water.
