EJECTION TURBOFAN

About Solution

A conventional fan does not cool the air itself. It only creates a flow of air that cools the surfaces of other objects.

The ejection fan cools the air already in its housing on 5-10 dergee of Celsius.

This effect is achieved by the fact that the fan cowl  has Lavale nozzle-shaped cuts.

When the propeller pump out  air from the casing, then air enters through the cone-shaped cuts.

According to Bernoulli's law, air is compressed in a wide part of the cuts, and when it leaves the narrow part, it expands  and cools.

The propeller does not spend additional energy on creating a vacuum inside the casing. So the work on cooling is carried out by atmospheric pressure.

Other configurations are possible with different propeller locations:
