Double-layer honeycomb aluminum core sound absorption and insulation board introduced into buried pipe
The invention provides a double-layer honeycomb aluminum core sound absorption and insulation board with an introduced buried pipe. Comprising a back plate layer, a second honeycomb aluminum core layer, a perforated plywood layer, a first honeycomb aluminum core layer and a perforated top plate layer which are arranged from bottom to top, wherein the second honeycomb aluminum core layer is formed by a plurality of honeycomb aluminum cores and comprises a plurality of sound absorption cavities; the perforated plywood layer comprises a plurality of plywood buried pipes; the first honeycomb aluminum core layer is formed by a plurality of honeycomb aluminum cores and comprises a plurality of sound absorption cavities; the perforated top plate layer is a sound absorption surface of the sound absorption and insulation plate, the positions of the top plate buried pipes, the sound absorption cavities of the first honeycomb aluminum core layer, the clamping plate buried pipes and the sound absorption cavities of the second honeycomb aluminum core layer are in one-to-one correspondence in the overlook direction and are sequentially communicated from top to bottom, and a plurality of sound absorption and insulation channels communicated with the sound transmission small holes of the sound absorption surface are formed; when sound enters the sound absorption and insulation channel, friction, resonance and thermal viscosity loss are generated to lose sound energy; the adaptive capacity of the sound absorption and insulation board in the severe environment can be improved, the overall noise reduction performance of the sound absorption and insulation board is improved, and meanwhile it is guaranteed that the structural material of the sound absorption and insulation board is safe and reliable.
本发明提出一种引入埋管的双层蜂窝铝芯吸隔声板，包括自下而上设置的背板层、多个蜂窝铝芯形成的含多个吸声空腔的第二蜂窝铝芯层、含多个夹板埋管的穿孔夹板层、多个蜂窝铝芯形成的含多个吸声空腔的第一蜂窝铝芯层、含多个顶板埋管的穿孔顶板层；穿孔顶板层为为吸隔声板的吸声面，各顶板埋管、第一蜂窝铝芯层的各吸声空腔、各夹板埋管、第二蜂窝铝芯层的各吸声空腔的位置在俯视向上一一对应且自上而下顺序连通，形成与吸声面的各传声小孔相通的多个吸隔声通道；当声音进入吸隔声通道后，产生摩擦、共振和热粘性损耗以损耗声能；本发明能提高吸隔声板在恶劣环境下的适应能力，提高吸隔声板的整体降噪性能，同时保证吸隔声板的结构材质安全可靠。
