Power train cooling requirements

The following are the major factors that determine the power train cooling requirements for a vehicle

The chemist s role is not limited to materials and analysis of designed components. The role also extends into power train applications and processes. Power train, refers to the set of components that generate power (engine) and deliver power (transmission, differential, and drive shafts) to the road. The combustion process, lubrication of components, and cooling requirements—along with ways to improve these processes and requirements—must be understood. The automotive chemist s tools and training allow for these challenges to be met properly as we head into the future. 

The conditions shown in Figure 10.47 are typical of those produced by a process simulator during the fourth step in process s)rnthesis, in which the heating and cooling requirements are established, as well as the power demands for the five-stage compression train. The former are tabulated below the... 

The compressor train is driven by the motor/generator, which has a pair of clutches that enable it to act as a motor when the compressed air is being generated for storage in the cavern, declutches it from the expander train, and connects it to the compressor train. The compressor train consists of a three-section compressor each section having an intercooler to cool the compressed air before it enters the other section, thus reducing the overall compressor power requirements. 

The passive contaimnent cooling water storage tank outlet piping is equipped wifli three sets of redundant isolation valves. Failure of a component in one train does not affect the operability of the other mechanical train or the overall system performance. The feil-open, air operated valves require no electrical power to move to their safe (open) position. The normally open motor-operated valves are powered fi om separate redundant Class 1 dc power sources.
