Abstract
An acoustically improved cooling system is provided for an energy storage system including a battery with air from a carpeted vehicle compartment, the cooling system including: a carpet portion sufficiently spaced from a floor panel of a vehicle to define a cavity forming an air passage through which air may flow and including an air inlet opening integrally formed therein through which the air from the compartment may be drawn; a fan for circulating air from the cavity into heat exchange relationship with the battery for cooling the battery; and a vent opening connecting the cavity and the fan in air flow communication. The frame is curved above the vent opening, to force noise reflection off the curved portion of the frame. A sound absorption layer is installed underneath the curved portion of the frame for noise attenuation.
