Abstract:
An air duct shell, comprising a first shell (11) and a second shell (14), wherein a plurality of first support ribs (12) are provided on one side of the first shell (11), and are criss-cross to form a plurality of first resonant cavities (13) separated from each other; the first resonant cavity (13) comprises a first opening; the first opening faces towards the side of the first support rib (12) distant from the first shell (11), and further comprising an acoustic energy resonance consumption part (2) connected to the first opening in a covering manner. The second shell (14) is connected to the side of the acoustic energy resonance consumption part (2) distant from the first shell (11). A vibration interval is provided between the second shell (14) and the acoustic energy resonance consumption part (2). Also provided are an indoor air-conditioning unit comprising the air duct shell, and an air conditioner. The air duct shell, the indoor air-conditioning unit, and the acoustic energy resonance consumption part on the first shell of the air conditioner can absorb the noise energy in the air duct shell, thereby improving the sound insulation and noise reduction performance of the air duct shell.
