Laser radar heat dissipation structure and laser radar

The utility model discloses a laser radar heat radiation structure comprising a housing, a rotor and a plurality of memory heat conduction members. Wherein the rotor is arranged in the shell; the memory heat conduction piece comprises fixed ends and free ends, and the fixed ends are arranged on the outer side wall of the rotor or the inner side wall of the shell at intervals. The utility model also discloses a laser radar comprising the laser radar heat radiation structure. Heat dissipation can be automatically adjusted according to internal and external temperature differences, and the devicecan be applied to heat insulation protection of laser radars in an extremely high-temperature environment. 本实用新型公开了一种激光雷达散热结构，包括壳体、转子和多个记忆导热件；所述转子设置于所述壳体内；所述记忆导热件包括固定端和自由端，多个所述固定端间隔设置在所述转子的外侧壁上或者所述壳体的内侧壁上。本实用新型还公开了一种激光雷达，包括上述的激光雷达散热结构。本实用新型能够根据内外温差自动调节散热，可应用于极端高温环境下激光雷达的隔热保护。
