The invention provides an automobile engine compartment sound-insulation and heat-insulation foaming plate, which comprises a closed-cell foaming plate layer and an open-cell foaming plate layer, andfurther comprises a vacuum heat-insulation plate layer, sound absorption cotton and a plurality of inserting columns. The vacuum heat-insulation plate layer is provided with a side-opening cavity; theclosed-cell foaming plate layer and the open-cell foaming plate layer form an opening spacing channel with the inner side wall of the side opening cavity of the vacuum heat-insulation plate layer along the transverse direction; one part of the inserting columns are arranged between the left longitudinal side wall of the open-cell foaming plate layer and the left longitudinal side wall of the sideopening cavity; one part of the inserting columns are arranged between the transverse side wall of the open-cell foaming plate layer and the top side wall of the side opening cavity, the other part of the inserting columns are arranged between the right longitudinal side wall of the open-cell foaming plate layer and the right longitudinal side wall of the side opening cavity, and the opening spacing channel is filled with the sound absorption cotton. Compared with the prior art, due to the fact that the structure is adopted, the sound insulation and heat insulation performance can be furtherimproved through the arrangement of the opening spacing channels and the structural arrangement of the sound absorption cotton and the inserting columns, and use is convenient.

    本发明提供一种汽车发动机舱隔音隔热发泡板,包括闭孔发泡板层、开孔发泡板层,还包括真空隔热板层、吸音棉、数根插柱,真空隔热板层具有侧开口腔,闭孔发泡板层和开孔发泡板层均沿横向方向与真空隔热板层的侧开口腔内侧壁构成开口间隔道,其中一部分插柱设置于开孔发泡板层的左纵向侧壁和侧开口腔的左纵向侧壁之间,一部分插柱设置于开孔发泡板层的横向侧壁和侧开口腔的顶侧壁之间,另一部分设置于开孔发泡板层的右纵向侧壁和侧开口腔的右纵向侧壁之间,吸音棉填充于所述开口间隔道。本发明与现有技术相比,由于采用了此种结构,通过设置开口间隔道,并结合吸音棉、数根插柱的结构设置,能够进一步地提升隔音、隔热性能,使用方便。
