fins: shapes & applications
Fin Type | Characteristics | Common Uses | |
---|---|---|---|
Louvered | Louvered fins increase the heat-transfer capacity by creating air turbulence which reduces the boundary layer on the fin's surface, but at a cost of increased air-pressure drop across the coil. |
|
|
Corrugated (low and high) | Corrugated fins improve the heat transfer factor to a lower degree than louvered fins. They also have a lower resistance to air flow. |
|
|
Sine Wave | Sine wave fins improve the heat transfer factor to a higher degree than corrugated fins. These have about the same resistance to air flow as the corrugated fins. |
|
|
Flat | Flat fins reduce ice accumulation on fins. They have the lowest resistance to air flow. |
