The structural composition of an automobile radiator
2026-02-25
Basic components:
Inlet/Outlet Chamber: Guides the coolant to flow into and out of the radiator.
Radiator core: The core heat-exchange area, composed of cooling tubes and fins, is primarily made of aluminum alloy (accounting for over 80%); copper is more commonly used in commercial vehicle applications.
Core structure:
Plate-type: The fine cooling tubes and heat sinks are arranged alternately. The cooling tubes feature a flattened circular cross-section to reduce air resistance and increase the heat transfer area.
Tubular-fin type: The corrugated fin strips and cooling tubes are arranged alternately and welded together. The heat dissipation area is 12% larger than that of the plate-fin type. The fins are equipped with louvered holes to disrupt the boundary layer of air, thereby enhancing heat dissipation performance.
Plate-type: Achieves efficient heat exchange through a flat-plate structure, suitable for the specific requirements of certain vehicle models.
Auxiliary components:
Fan: Forces air flow to enhance heat dissipation. The electric fan can automatically adjust its speed for precise cooling.
Thermostat: Controls the coolant circulation path to ensure the engine warms up quickly or dissipates heat efficiently.
Expansion tank: Stores coolant and compensates for volume changes in the system caused by temperature fluctuations.
