What are the performance indicators of a radiator?
The key indicators for evaluating the performance of radiators include:
Thermal Resistance:
The ability of a radiator to transfer heat, measured in ℃/W (temperature rise per watt of power).
The lower the thermal resistance, the better the heat dissipation performance.
Heat dissipation area:
The larger the fin area, the more it comes into contact with air, and the higher the heat dissipation efficiency.
Wind volume and pressure (air-cooled):
Airflow (CFM): The volume of air passing through a fan per unit of time.
Wind pressure (mmH ? O): The ability of a fan to overcome resistance and push air.
Pump flow rate and head (water cooling):
Flow rate (L/h): The amount of circulating water-cooled liquid per unit time.
Head (m): The height at which the water pump overcomes resistance to push the coolant.
Noise:
The fan speed and airflow design directly affect the noise level and need to be balanced between heat dissipation and quietness.
