[0028] Working principle:

[0029] The water circulation adopted by the engine flows from the inlet pipe of the high-temperature water dissipation inlet and outlet pipe 23 into the high-temperature water dissipation core body 21 for heat dissipation. The water after being dissipated by the high-temperature water dissipation core body 21 flows back into the water circulation of the engine through the outlet pipe of the high-temperature water dissipation inlet and outlet pipe 23 to dissipate heat from the engine. The high-temperature water dissipation expansion tank 7 is used to reduce the pressure fluctuation in the high-temperature water radiator 2 and improve the safety and reliability of the operation of the high-temperature water radiator 2;

[0030] The water circulation adopted by the radiator of the motor controller flows into the low-temperature water dispersion core 31 through the water inlet pipe of the low-temperature water dispersion inlet and outlet pipe 33 for heat dissipation. The water after heat dissipation by the low-temperature water dispersion core 31 returns to the water circulation of the motor controller radiator through the water outlet pipe of the low-temperature water dispersion inlet and outlet pipe 33 to dissipate heat from the motor controller; the low-temperature water radiator expansion tank 8 reduces the pressure fluctuation of the low-temperature water radiator 3 and improves the safety and reliability of the operation of the low-temperature water radiator 3.

[0031] The high-temperature air flow after supercharging by the turbocharging system flows into the intercooler core 41 through the air inlet pipe in the air inlet and outlet pipe 43 for heat dissipation and cooling. The cooled air flow is discharged into the engine through the air outlet pipe in the air inlet and outlet pipe 43 to reduce the heat load of the engine and increase the air intake.

[0032] The low-temperature gaseous refrigerant flowing out of the liquid outlet pipe in the inlet and outlet liquid pipe 511 of the condenser body 51 is extracted by the compressor 6 to the cold side channel of the plate heat exchanger 53. The circulating medium of the battery pack heat dissipation device is connected to the hot side channel of the plate heat exchanger 53. Heat exchange and cooling are carried out between the low-temperature gaseous refrigerant in the plate heat exchanger 53 and the circulating medium of the battery pack heat dissipation device, so as to realize the heat dissipation and cooling of the battery pack. The high-temperature liquid refrigerant flowing out of the hot side channel of the plate heat exchanger 53 is dried by the drying liquid storage tank 54 and then returns to the low-temperature gaseous refrigerant after heat dissipation by the condenser body 51; the plate heat exchanger 53 is connected to the plate heat exchanger expansion tank 9 through a connecting pipe, and the plate heat exchanger expansion tank 9 reduces the pressure fluctuation of the circulating medium in the hot side channel of the plate heat exchanger 53 and improves the safety and reliability of the operation of the plate heat exchanger 53.

[0033] The high-temperature water radiator 2, the low-temperature water radiator 3, the intercooler 4 and the condenser body 51 are forced air-cooled and heat-exchanged by two symmetrically arranged fans 13.

[0034] The integrated heat dissipation device for unmanned vehicles disclosed in this embodiment dissipates heat from the water circulation of the engine through the high-temperature water radiator 2, dissipates heat from the water circulation of the motor controller radiator through the low-temperature water radiator 3, dissipates heat and cools the high-temperature air flow after supercharging by the turbocharging system through the intercooler 4, and exchanges heat and cools the circulating medium of the battery pack heat dissipation device through the condenser assembly 5.
