![]() ![]() The cooling efficiency is determined by the amount of fluid touching the tubes resulting in direct cooling. Sometimes the tubes have a tabulator to increase the turbulence of the coolant flowing through them. The fins conduct heat from the tubes and transfer the heat to air passing through the radiator. The coolant passes through the many aluminum tubes that are mounted in parallel arrangement from the inlet to the outlet through these tubes. Modern vehicles have radiators made using “brazing thin aluminum fins” to the flattened aluminum tubes. All the tubes are connected by the radiator hose. The hot coolant flowing from the engine enters the radiator through the inlet tube and from the outer part of the engine. The inlet and outlet tubes are found in the radiator. This is the point of entry and exit of the coolant liquid on the radiator. The pressure cap bleeds off the hot coolant, preventing it from damaging other cooling parts, which can happen if the pressure cap is broken or not working. The pressure cap seals off your car radiator to create pressure inside, which ultimately increases the boiling point of the coolant liquid. The pressure keeps the coolant hotter without it boiling, making the cooling more efficient. The coolant inside the radiator is always under pressure. There are one-core radiators, two-core and three-core radiators. The core classifies radiators depending on the number of cores and materials. The core mainly transfers heat from the flowing hot coolant into the air through the vent. The core is the central part of a radiator and has coiled tubes and small metal fins. This coolant circulates to prevent the car engine from overheating. The coolant liquid goes beyond the normal radiator functions as it acts as a lubricant and fights rusting. Water-cooled engines use water coolants mixed with antifreeze to withstand extreme temperatures. Coolants come in liquid form or gaseous form. The coolant liquid conducts heat away from your car engine, radiator, and transmission. A cracked radiator can leak the coolant bringing the coolant level down which causes the engine to overheat. The coolant continuously flows through the radiator to disperse heat. The car coolant is never a standalone feature as it runs through the car engine and back through the radiator for heat transfer. Understanding how radiation works are the first step towards fixing any problems that may arise. The coolant and transmission fluid flow across the radiator and air passes the radiator fins removing the heat from the fluids. Car radiator parts play a major role in cooling the engine by ensuring efficient heat transfer from the circulating coolant. Modern cars have radiators made of aluminum. In other words, the radiator cools the coolant and transmission fluid. The radiator transfers heat from the hot coolant flowing through it to the air blown via the radiator fan. ![]() The car radiator functions as a heat exchanger and is located behind the grille next to your engine. ![]()
