The invention provides a ventilation opening structure for a heat dissipation device of an engine compartment. The ventilation opening structure structurally comprises connecting pieces, positioning grids, a frame, mounting grooves and ventilation holes. The connecting piece is communicated with the positioning grid, the positioning grid is embedded into the side end of the frame, the frame and the mounting groove are of an integrated structure and are connected with the connecting piece, and the ventilation hole penetrates through the center of the mounting groove; after the connecting piece is further improved, the clamping blocks can be matched with the noise reduction layer and other components, the clamping blocks can assist the attaching layer to improve the overall connection performance with the heat dissipation device, the displacement condition generated by continuous vibration is further prevented, meanwhile, noise generated by gas exhaust can be eliminated as much as possible through noise reduction cotton of the noise reduction layer, and the noise reduction effect is good. And in addition, according to the sealing layer, the stability of gas exhaust can be improved, and the diffusion phenomenon is prevented.
本发明提供一种发动机舱的散热装置用通风口结构,其结构包括:连接件、定位格、框架、安装槽、通风孔;连接件与定位格相通,定位格嵌入于框架的侧端,框架与安装槽为一体化结构并与连接件相连接,通风孔贯穿于安装槽的中心部位;本发明由连接件进一步改进后,其可通过新增的卡块与消音层等部件的相互配合,卡块可辅助贴合层来提升与散热装置的整体连接性能,进一步防止持续震动所产生的位移情况,同时消音层的消音棉可将气体排出所产生的噪音尽数消除,达到无声排气的效果,并且根据密闭层能提升气体排出的稳定性,防止扩散现象的产生。
