Meanwhile, the heat dissipation pipeline of the unmanned computing platform is connected in parallel in the whole vehicle heat management system, temperature control is little influenced by other parts, and the unmanned computing platform is guaranteed to be good in heat dissipation effect and stable in temperature. In addition, as the power and the generated heat of the unmanned computing platform, the driving motor and the motor controller are changed, the temperature of the cooling liquid in the thermal management system is changed, and the volume of the cooling liquid is also changed; thus, the pressure formed in the thermal management system is different from the atmospheric pressure, and the cooling liquid in the expansion water tank automatically enters the radiator under the action of the pressure difference, so that automatic liquid supplementing is realized.
