1. Flow Type:Crossflow Radiators:Coolant flows horizontally across the radiator core, usually from one side tank to the other.Downflow Radiators:Coolant flows vertically down through the radiator core, from a top tank to a bottom tank.
2. Material Type:Aluminum Radiators:Commonly used in modern vehicles due to their lightweight and efficient heat transfer properties.Copper-Brass Radiators:Traditional material, often found in older vehicles, known for good heat dissipation but heavier than aluminum.Plastic Radiators:Used in conjunction with aluminum cores, often for the tanks, to reduce weight and cost.
3. Core Construction:Single Core Radiators: Have a single row of tubes and fins, suitable for standard vehicles.Dual Core Radiators: Feature two rows of tubes and fins, offering increased cooling capacity for high-performance engines or vehicles in demanding conditions.
4. Other Considerations:Dual Pass Radiators: Coolant travels through the core twice, enhancing heat dissipation.Performance Radiators: Often feature larger cores, increased fin density, and enhanced materials for improved cooling in high-performance applications.Electric Radiators: Some vehicles may utilize electric water pumps and radiators, often in hybrid or electric vehicle systems.
