Car Radiators

Car Radiators Information

Car radiators are used to cool the engine coolant liquid that is used to cool and engine as it is in use.

The coolant that flows around the engine and cylinder heat, taking away the heat that is produced in order to keep the engine at it optimum operating level. The coolant with this extracted heat is then pumped back through to the radiator where this heat is then expelled and cooled by air passing through it then; it is returned back to the engine in a closed loop.

Car radiators consist of a pair of header tanks, these are linked by a core that has lots of narrow passageways and this increases its surface area. The core is usually constructed from layers of sheet metal that are pressed together to form channels that are brazed or soldered together. In the past car radiators were made from brass or copper cores that were soldered to brass header tanks.

Modern car radiators save weight and money by constructing it using plastic headers and in some cases, aluminium cores. If this type of car radiator construction was to fail, there is less of a chance that they can be repaired.

Most cars only have one radiator; sometimes some cars are fitted with a second radiator to increase the cooling capacity. Hyper-cars such as the Bugatti Veyron have a total of 10 radiators.
