increases its total surface area, resulting in greater cooling effectiveness. There are two types of cooling pads that can be used for air cooling: one is the honeycomb design and another one is

is the height over sea level in meters. And the result is the factor that should be multiplied with the cooling capacity in to get the cooling capacity at the specified height over sea level.

When operating in an environment with lower air pressure like high altitude or airplane cabins, the cooling capacity has to be derated compared to that of sea level.

In all cases, the air has to be cooler than the object or surface from which it is expected to remove heat. This is due to the
