Design of the Plenum Chamber for Reducing Cooling Fan Noise of the Console for Combat Systems in a Naval Vessel

Indoor noise is very important related to the morale and fighting power of the crew as well as environmental condition for them in a navel vessel. Especially, the crew members working in CIC(Combat Information Center) and sonar equipment room require much more quiet environment condition in order to increase the performance of their combat system. One of the most serious noise source in CIC is the cooling fan noise installed in the console of the combat system. Therefore, in this paper, the design of the plenum chamber is studied to reduce the noise of the fan from these consoles by numerical analysis.
