Abstract

The invention discloses a heat dissipation structure of laser radar and laser radar, wherein the heat dissipation structure of laser radar includes a cooling cavity arranged inside the hollow cavity of laser radar, and the heat dissipation structure also includes an inlet and an outlet arranged on the hollow cavity, and the inlet The outlet is connected to the cooling cavity respectively, and the refrigerant can flow through the cooling cavity through the inlet and the outlet. The specific refrigerant enters the hollow cavity through the inlet, flows through the hollow cavity and then is discharged through the outlet, so as to dissipate the cooling capacity of the external refrigerant When entering the hollow cavity or when the refrigerant passes through the hollow cavity, it absorbs the internal heat of the hollow cavity, and then discharges it from the outlet, so as to reduce the internal heat of the hollow cavity, indirectly improve the heat dissipation of the laser radar, and further improve the stability and stability of the laser radar. reliability.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a heat dissipation structure of a laser radar and the laser radar. Background technique [0002] Various electronic components are arranged inside the rotor of the laser radar. The laser radar housing is a closed structure. The internal lasers, motors and other components will generate a large amount of heat during operation. The heat dissipation performance of the laser radar directly affects the working of the laser radar. stability and reliability. The high temperature working environment will easily cause the device to work outside its allowable temperature, reduce the service life, and ultimately affect the service life of the entire radar. In addition, some devices need to work in a relatively suitable temperature environment. If the temperature is too high, the performance of the device itself will be degraded, which will affect the accuracy and ranging of the entire radar....
