Duct structure (22) is disposed in an engine compartment (10) of an automotive vehicle and comprises a main air passageway (32) that runs from an intake (34) at one end to an outlet (36) at an opposite end. A section of the length of passageway (32) is disposed to run alongside a vertical wall of the casing of a battery (24) that is toward an engine (12). Heat impinging on the duct structure is dissipated to the airflow through the passageway. Various features are integrated with the duct structure including resonators (38, 40), a deflector (48), and a battery enclosure (50) for containment of electrolyte that is accidentally spewed or leaked from the battery casing so that the liquid does not entrain with the intake airflow to the engine.

[ What is claimed is:] [1.]1. In an engine compartment of an automotive vehicle that houses an internal combustion engine having an air intake system and that also contains an electrical system storage battery in spaced apart relation to the engine;duct structure that forms a portion of the air intake system and comprises an inlet at which intake air enters and a passageway that conveys the intake air from the inlet, lengthwise through the passageway, to an outlet;a portion of the length of the passageway being disposed in covering relation to a wall of the battery that is toward the engine;a branch that is disposed in covering relation to another wall of the battery and that comprises a space that is open to the passageway, but otherwise closed;another branch that is disposed in covering relation to a further wall of the battery and that comprises a space that is open to the passageway, but otherwise closed; and whereinat least one of the branches is constructed and arranged to form a resonator for tuning the air intake system to operation of the engine.
