Abstract
A vehicle cooling system for a mobile vehicle consists of three essential parts. These are a compressed air reservoir, a heat exchanger and a duct connecting the reservoir and the heat exchanger. On demand, the compressed air will be released to the duct and will expand (as the end connected to the reservoir is expected to be lower in cross-sectional area compared to the end connected to the face of the heat exchanger). This expansion will lead to the reduction in air temperature. This helps in increasing the heat rejection capacity of the cooling system. The colder air passes through the heat exchanger and carries away the heat. This air exits from the other end of the heat exchanger into the environment. A fan is optional to operate behind the heat exchanger to help draw the air though it. The compressed air may originate in the vehicle air system for operating air brakes found on medium and heavy-duty trucks or the compressed air may originate from a separate air compressor. The system may be located in various locations on the vehicle due to the lack of reliance on ram air caused from vehicle movement.
