Cooled (or air conditioned) seats work by confining cooled air directly in the seat where the passenger is seated. Multiple fans are put within the seat to provide air circulation. The air from the fans blows through a diffusion layer to spread the cool air throughout the seating material, cooling the whole surface.
The carâs cooling system is responsible for carrying heat away to the outside air. The cooling fan motor powers the cooling fan, which keeps the engine from overheating. The fan is located in the engine compartment, at the front or rear of the radiator.The fan cools the coolant as it passes through the radiator.he cooling fan motor powers the cooling fan, which keeps the engine from overheating.
