Frontal cooling

The purpose of the frontal cooling is for the cooling down of the engine and vehicle components in the engine compartment

Installed is a tracking system in the existing modified chassis dynamometer. This is tightly connected to the sound proof cabin. 
A tracking system is installed at this portal and a feeding unit with a high power fan is operated manually in front of the test vehicle allowing cool air to flow directly towards the car cooling unit. Within the portal the fan can shift from the middle of the test bench up till the exterior part of the car. This is operated by a spur gear motor is used together with a belt drive. Controls are from the installed switch board at the portal or from the SPS chassis dynamometer.

The ventilator suctions freely unfiltered air by means of a fan protective grid in the sound proof cabin making this therefore a circulating ventilation system. 

In order to adjust air flow to the car there are 3 air diffusers in the bottom unit area of a 360° adjustable nozzle and in the upper part of the unit installed is a ventilation grid with louvers and a hit-and- miss damper for quantity control.
This way air leaks can be adjusted in such a way that the cooling air intake speed of the car is 8 m/s or higher. 

If the wheel base adjustment of the chassis dynamometers on the front axle takes place, in different car types with different wheelbases and different distances between the cars radiator surface and air outlet components. This should be between 150 and 700 mm. 

The amount of air discharged is about 10.000 m³/h. On the basis of this part of the air during discharge is deviated by turbulences and passes by the radiator surface, in a car approx. 7000 m³/h an.
