![]() This coolant is then returned into the radiator.Īlthough the surface area of a vehicle does have a cooling effect, the added facility of a fan situated between the engine and radiator, adds effective efficiency to the cooling process. This liquid coolant combination is retained in the radiator and when entering the engine, it is dispatched around the cylinders, collecting the heat created by friction and burning fuel. ![]() As the heat of the engine increases and attains a defined temperature, this thermostat opens, permitting the flow of coolant and water. This creation of turbulence within the tubes helps maintain the temperature of the fluid touching the tubes, making it possible for more heat to be extracted during the process, with all fluid inside the tube utilised to maximum efficiency.Ĭlose to the front of a car engine is located a thermostat. This system enables a smooth and even flow of fluid through the tubes. In various instances, the tubes have a type of fin insert, which increases the turbulence of the fluid flowing through the tubes. An engine coolant flows from the inlet source to the outlet by way of thin tubes mounted in a parallel arrangement, from which heat is transferred into the air flowing through the radiator. ![]() The majority of radiators in modern vehicles are manufactured from aluminium. The function of a radiator may best be described as a heat transference system, whereby the heat from hot coolant flowing through, is dispersed by the fan. ![]()
