Heat dissipation structure of laser radar

Abstract

A heat radiation structure of a laser radar is disclosed by the present invention and comprises an outer shell, an inner shell and a heat radiation fan, the inner shell is arranged in the outer shell, an interlayer space is arranged between the inner shell and the outer shell, a laser radar assembly is arranged in the inner shell, the outer shell is equipped with a vent hole enabling the interlayer space to be communicated with the external space, and the heat radiation fan is arranged on the outer shell. And air circulation between the interlayer space and the external space can be accelerated. The outer shell has the effects of protecting the inner shell and rectifying inlet air, the laser radar assembly can be separately mounted on each side wall of the inner shell, so that the structure is more compact, the volume miniaturization design is facilitated, heat generated by the laser radar assembly is guided out from each side wall of the inner shell and diffused to the whole inner shell, and the heat dissipation effect is greatly improved. Meanwhile, the heat radiation fan is matched to enhance air flow in the interlayer space to improve the cooling efficiency, the cooling effect is good, it is ensured that the laser radar assembly can normally and stably operate for a long time, the working stability is good, and wide application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a heat dissipation structure of laser radar. Background technique [0002] LiDAR instruments have certain heat dissipation requirements, and there are a certain number of power consumption components on an instrument, so the heat dissipation problem will definitely affect the performance of the instrument. At present, the heat dissipation structure commonly used in lidar instruments is mainly: at the bottom of the instrument, a material with high thermal conductivity is in contact with the heating device to conduct the energy of the heating device, and through the heat sink in contact with the air, the energy of the heat conducting material is conducted out. In the above method, the bottom of the instrument is in contact with the heating device, and the heat sink is in contact with the air, so more metal materials will be used, which increases the weight and cost of the produ...

AI Technical Summary

Problems solved by technology

It dissipates heat through the base, and this structure requires power-dissipating components to be placed at the bottom of the whole, which limits the placement of power-dissipating components and also limits the overall shape and size of the product

Moreover, the heat dissipation method adopts a passive heat dissipation method to dissipate heat, and it ends after the components are conducted to the heat dissipation base. This technical solution limits the overall radar appearance size and heat dissipation performance
