Abstract

The invention discloses an air conditioner unit heat preservation panel with a sound attenuation function. The air conditioner unit heat preservation panel with the sound attenuation function comprises a perforated sound absorbing plate, a glass wool layer, an inner metal plate, a heat preservation layer and an outer metal plate which all are sequentially stacked from interior to exterior. The perforated sound absorbing plate is provided with micropores which are evenly distributed, the hole diameters of the micropores are 0.5mm-1.0mm, and the percentage of holes of the perforated sound absorbing plate is 1%-3%. The thickness of the inner metal plate and the thickness of the outer metal plate are identical. The thickness of the perforated sound absorbing plate is 0.5%-4% of the thickness of the glass wool layer. The thickness of the outer metal plate is 0.25%-4% of the thickness of the heat preservation layer. The perforated sound absorbing plate faces a noise source, the noise is absorbed by the micropores and the relatively thick glass wool layer, and the noise can be greatly weakened; the heat preservation layer plays a very good role in separating a cold bridge and preserving heat, and the combination of the perforated sound absorbing plate and the heat preservation layer achieve functions of noise reducing and heat preserving at the same time; and in addition, by means ofa first separation layer and a second separation layer which have certain thicknesses, the heat preservation and noise insulation effects of the air conditioner unit heat preservation panel can be more excellent.

Description

technical field

[0001] The invention relates to the field of thermal insulation and sound insulation materials, in particular to a thermal insulation panel with a sound-absorbing function for an air-conditioning unit. Background technique

[0002] Insulation panels are widely used in air-conditioning and refrigeration equipment as a structural component for heat preservation. They only have the function of heat preservation, but have no effect of sound absorption and noise reduction. In order to reduce noise, it is necessary to make a muffler in the air supply system for sound absorption and noise reduction, resulting in increased wind resistance, increased energy consumption, and increased costs. For this reason, a panel with both functions of sound attenuation and heat preservation is specially designed and developed. This structure includes a perforated sound-absorbing panel, a glass wool layer, an inner metal plate, an insulating layer and an outer metal plate that are s...
