The invention discloses a heat dissipation system arrangement structure of a pure electric heavy truck. The heat dissipation system arrangement structure comprises a motor heat dissipation loop and a battery heat dissipation loop. The motor heat dissipation loop comprises a motor heat dissipation water tank, a first water pump, a driving motor and an electric control accessory which are sequentially connected, and a water outlet of the electric control accessory is connected with a water return port of the motor heat dissipation water tank. The battery heat dissipation loop comprises a power battery and a battery cooling unit which are connected with each other, and the battery cooling unit is used for cooling the power battery. A first branch is arranged between the first water pump and the driving motor and is connected with a water return port of the power battery through a first control valve; a water outlet of the power battery is provided with a second branch, and the second branch is connected with a water return port of the power battery through a second control valve. According to different working conditions, the working modes of the system are synchronously switched, the working efficiency of the heat dissipation circulating system is improved to the maximum extent, power consumption is reduced, and the purposes of energy conservation and environmental protection of the whole vehicle are achieved.
