Non obstructable coolers 

Engine and intercooler coolers are laminar flow type placed in the cofferdam

 

LAMINAR FLOW

Cooling of the engine and turbo interccoler is realized by a peculiar system of radiators.
Radiators consist of a circuit which is passed through by a flowing fluid. The fluid absorbs heat from the engine and passes through a circuit that cools down the fluid before it returns to the engine. As a great amount of heat has to be dissipated a great exchange area is needed. To ensure a more efficient exchange a cooling fluid cross the external face of the exchanger.
Traditional radiators are finely perforated permitting the passage of the second fluid(air) through it's surface.
But for the MACP it was not possible to use traditional radiators.
MACP condition of work will roughly be a muddy environment, characterised by high temperatures and a high rate of humidity. MACP will pass across a great amount of debris that will affect the operations of this kind of vehicle, with consequent bad effects on cooling systems efficiency.
Indeed there will, rather often, be the possibility that leaves plastic bags or other light objects will cover the radiators and make partially unserviceable a traditional type of heat exchangers.
For these reasons MACP Cooling system is constituted by unconventional coolers where the external fluid does not pass through the holes on the surface but skirts the exchanger surface. These surfaces are positioned inside the lift-air ducts and work using the already existing air flow coming from lift fans without installing other devices.
