A car radiator is the central component of an internal combustion engine's cooling system. It dissipates intense heat generated by engine combustion, transferring thermal energy from circulating liquid coolant into ambient airflow.
Key Construction & Components
Radiator Core: Aluminum tubes and cooling fins maximizing heat dissipation surface area.
Plenum Tanks: Plastic or brass side tanks directing coolant inlet and outlet flow.
Radiator Pressure Cap: Maintains pressure to elevate coolant boiling threshold.
Cooling Fan Assembly: Pulls air through fins during idling and slow traffic.
