3.2 Operation, function
The medium to be cooled is – depending on volumetric flow
rate– flowing through the cooler core either in one pass or
multiple passes and is cooled by the ambient air produced
by the fan.
The regular fan is a suction fan but can also be supplied as
pressure fan if required by the order specification.
To reach a high heat dissipation , oil- and air fins, fan blades
and motor power are optimally synchronised.
3.0 Design & functional description
3.1 Design, main components, materials, accessories
For a most efficient application cooling to 5 – 6 K above the
ambient air temperature is recommended.
To cool down to values below ambient air temperature is not
possible.
