Brush in the direction of the radiator fins to remove dirt and grim (not against -- this may cause damage the fins).
The design parameters consisted of the fin geometry (i.e., length, thickness, arrangement, and number of fins), coolant direction, exchanger wall thickness, and the length of the heat exchanger.
It has been experimentally proven that the heat transfer coefficient may not be uniform and there are large differences in the heat transfer coefficient both from fin base to fin tip and along the fin in the direction of the airflow.
Defining a base-case for the fin geometry, fin thickness, fin radius and number of fins are increased.
Various types of fins achieved enhancement in the performance such as longitudinal fins, corrugated fins and fins attached with baffles.
The increased number of fins resulted in a reduction of the space between fins.
If your country has yet to ban the act of finning or sale of fins, make your voice heard.
Try different shapes of fins.
The fins are arranged perpendicular to the direction of air flow to enhance the heat transfer rate and efficiency.
The tubes are externally finned with continuous plate fins and the tube rows are arranged staggered in the direction of the air flow.
