Problems solved by technology

[0002] The detection device of the laser radar is equipped with various electronic components. The heat dissipation design for the electronic components can usually conduct heat to the detection device body smoothly. However, since the detection device body and the lidar shell are not in direct contact, the detection device The heat exchange between the housing and the lidar can only rely on air convection, which leads to a large thermal resistance between the detection device and the radar housing. In order to reduce the thermal resistance of this link, it is necessary to optimize the thermal resistance between the detection device and the radar housing. heat exchange

Abstract

The invention discloses a laser radar and a heat dissipating device thereof. The heat dissipating device of the laser radar is located between a top cover of the laser radar and a detecting device ofthe laser radar; the heat dissipating device comprises an impeller and a first heat dissipating part arranged around the impeller, wherein the impeller and the first heat dissipating part can rotate along with the rotation of the detecting device, and the rotation speed of the impeller is set to be greater than that of the first heat dissipating part, so that air is driven to circularly flow through the first heat dissipating part, the top cover and the detecting device when the impeller rotates along with the detecting device.

Description

technical field [0001] The present application relates to the field of ranging, in particular to a laser radar and a heat dissipation device thereof. Background technique [0002] The detection device of the laser radar is equipped with various electronic components. The heat dissipation design for the electronic components can usually conduct heat to the detection device body smoothly. However, since the detection device body and the lidar shell are not in direct contact, the detection device The heat exchange between the housing and the lidar can only rely on air convection, which leads to a large thermal resistance between the detection device and the radar housing. In order to reduce the thermal resistance of this link, it is necessary to optimize the thermal resistance between the detection device and the radar housing. heat exchange. Contents of the invention [0003] The purpose of this application is to provide a laser radar and its heat dissipation device, which ...
