摘　　要：高性能的激光雷达需要额外辅助散热,不同的散热方式意味着不同的布置方案,即要求整车不同零部件进行匹配设计,同时也会对造型的设计、结构匹配设计、零部件材料的选择以及对人体感观的影响提出要求,进而确定方案的可行性。同时论述自然风冷却激光雷达的布置方案的实施路径,从流场设计、风噪消除、密封设计、隔振设计及模态提升等方面进行了方案的分析。The high-performance LiDAR requires additional auxiliary heat dissipation.Differ⁃ent heat dissipation methods imply different layout schemes,which require matching design of differ⁃ent vehicle components.It also imposes requirements on the style design,structural matching,mate⁃rial selection of components,and the impact on human sensory perception,thereby determines the feasibility of the scheme.At the same time,the implementation path of the layout scheme for natural air cooling of the LiDAR is discussed,and the scheme is analyzed from the design of the flow field,wind noise elimination,sealing design,vibration isolation,and modal improvements.
