In some embodiments of the present utility model, the inner cover 70 includes the composite plate 90, wherein the inner cover 70 may be integrally formed by the composite plate 90, or may be partially formed by the composite plate 90, the inner cover 70 is covered on at least part of the outer side of the compressor assembly 50, and noise generated when the compressor assembly 50 operates can be effectively enclosed inside the inner cover 70, thereby reducing vibration and noise transmission to the outside, and the outer casing 20 is used to secondarily enclose the vibration and noise, thereby further reducing vibration and noise transmission to the outside, and further improving vibration and noise reduction effects of the outdoor unit of the heating and ventilation device.

In some embodiments of the present utility model, the casing 20 and the inner cover 70 are both composed of the composite board 90, the casing 20 and the bottom board 10 are surrounded to form an accommodating space, the inner cover 70 is disposed in the accommodating space, at least part of the body of the compressor assembly 50 is covered by the inner cover 70, the double-layer structure formed by the casing 20 and the inner cover 70 is used to seal noise in the operation process of the compressor assembly 50, thereby reducing the noise transmission to the outside, meanwhile, the casing 20 and the inner cover 70 are both composed of the composite board 90, on the basis of the double-layer structure formed by the casing 20 and the inner cover 70, the composite board 90 has good vibration and noise reduction performance, so that mechanical energy in the vibration process can be absorbed by the composite board 90 in the vibration transmission process, the transmission of vibration is reduced, the vibration and noise reduction effect on the outdoor unit 100 of the heating and ventilation device is improved, and the use experience of a user is improved.

Specifically, when the thickness of the sheet metal layer 91 is less than 0.2mm, the sheet metal layer 91 is difficult to process and has high manufacturing cost, and meanwhile, the strength of the sheet metal layer 91 is relatively low, so that the use requirement of the outdoor unit 100 of the heating and ventilation equipment cannot be met; when the thickness of the sheet metal layer 91 is greater than 5mm, the thickness of the sheet metal layer 91 is greater, which results in a greater overall thickness of the composite plate 90 and occupies the internal space of the outdoor unit 100 of the heating and ventilation device, thereby reducing the space utilization of the outdoor unit 100 of the heating and ventilation device and increasing the weight of the outdoor unit 100 of the heating and ventilation device.

In the present utility model, the thickness of the sheet metal layer 91 is set to 0.2mm to 5mm (including 0.2mm and 5 mm), so that the influence of the composite plate 90 on the space utilization of the outdoor unit 100 of the heating and ventilation apparatus can be reduced while ensuring the strength.

Specifically, when the thickness of the sheet metal layer 91 is less than 0.002mm, the damping layer 92 is relatively thin, so that the vibration and noise reduction effect is poor, and the vibration and noise reduction requirement of the outdoor unit of the heating and ventilation equipment cannot be met; when the thickness of the sheet metal layer 91 is greater than 5mm, the thickness of the sheet metal layer 91 is greater, which results in a greater overall thickness of the composite plate 90 and occupies the internal space of the outdoor unit 100 of the heating and ventilation device, thereby reducing the space utilization of the outdoor unit 100 of the heating and ventilation device and increasing the weight of the outdoor unit 100 of the heating and ventilation device.

In the embodiment of the present utility model, the thickness of the damping layer 92 is set to 0.002mm to 5mm (including 0.002mm and 5 mm), so that the influence of the composite plate 90 on the space utilization of the outdoor unit 100 of the heating and ventilation apparatus can be reduced while the vibration and noise reduction effects are ensured.

It is noted that the thickness of the sheet metal layer 91 may be 0.002mm, 0.005mm, 0.01mm, 0.015mm, 0.02mm, 0.025mm, 0.03mm, 0.035mm, 0.04mm, 0.045mm, 0.05mm, 0.055mm, 0.06mm, 0.065mm, 0.07mm, 0.075mm, 0.8mm, 0.085mm, 0.09mm, 0.095mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm … … mm.
