An aluminum honeycomb sandwich composite board is internally provided with a gas passage for air flow to pass through, and comprises an aluminum honeycomb core layer formed by arranging a plurality of hollow aluminum honeycomb core grids; the first aluminum cover plate is connected to one axial end face of the aluminum honeycomb core layer, and a first connecting part is formed; the first aluminum cover plate is connected to one axial end face of the aluminum honeycomb core layer and forms a first connecting part, the second aluminum cover plate is connected to the other axial end face of the aluminum honeycomb core layer and forms a second connecting part, the first connecting part comprises a first ventilation groove, the second connecting part comprises a second ventilation groove, and the first ventilation groove and the second ventilation groove form the gas channel. The first ventilation grooves and the second ventilation grooves are different in sectional area in the direction perpendicular to the air flow passing direction, so that the flow resistance of air passing through the first ventilation grooves and the second ventilation grooves is different, the flow speed difference is formed between an air channel where the first ventilation grooves are located and an air channel where the second ventilation grooves are located, and then the pressure intensity difference is formed.
一种铝蜂窝夹层复合板,其内部形成有供气流通过的气体通路,包括:铝蜂窝芯层,所述铝蜂窝芯层由多个空心的铝蜂窝芯格排列而成;第一铝盖板,所述第一铝盖板连接于所述铝蜂窝芯层的轴向一个端面,且形成第一连接部位;以及第二铝盖板,所述第二铝盖板连接于所述铝蜂窝芯层的轴向另一个端面,且形成第二连接部位,所述第一连接部位包括第一通风槽,所述第二连接部位包括第二通风槽,所述第一通风槽和所述第二通风槽形成所述气体通路,所述第一通风槽与所述第二通风槽在垂直于气流通过方向上的截面面积不同,以使从其中通过的气体的流阻不同,从而在所述第一通风槽所在的气体通路与所述第二通风槽所在的气体通路之间形成流速差,进而形成压强差。
