Thermal - Acoustic enclosure

An enclosure (27) for apparatus that, during operation, generates heat and/or sound energy comprises at least one wall (26) defining at least a portion of the enclosure hollow interior. The wall (26) comprises in sequence outwardly from the enclosure hollow interior an inner panel (28), an outer panel (30), a support frame (32) between the inner (28) and outer (30) panels to hold the inner (28) and outer (30) panels spaced apart, and a vibrator isolator (64) between the support frame (32) and the panels (28,30). Panels (28,30) or panel segments of the wall (26) primarily are made of non-metallic composites to provide a structurally strong, lightweight enclosure (27) that includes enhanced acoustic characteristics and reduced heat transfer through enclosure walls (28,30), along with fire protection and in-plane shear loading capabilities.
