Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle thermal management control, in particular to an integrated thermal management system of a transport vehicle and a control method thereof and an electronic device. BACKGROUND

[0002] In the related art, the current transport vehicles (such as heavy-duty cold chain transport vehicles) mainly face the following key problems:

[0003] 1) Complexity of multi-system coordination and integration. Long-distance transport vehicles usually require multiple thermal management subsystems. The demand for heat and the heat dissipation of each subsystem vary significantly with the working condition, and the control requirements for temperature are also different.

[0004] 2) A large amount of waste heat generated by the fuel cell system is not effectively recycled, resulting in significant energy waste, which is not conducive to improving the vehicle range;

[0005] 3) Transport vehicles, such as heavy-duty cold chain transport vehicles, have very high performance requirements for refrigeration systems, resulting in huge power consumption, shortening the range, and indirectly increasing the whole life cycle operating cost, which has become the main bottleneck restricting the development of long-distance pure electric cold chain transport vehicles;

[0006] 4) At present, environmental protection regulations are becoming more and more stringent worldwide. Traditional fuel-powered cold chain transport vehicles are limited by their emission levels, and their future development space will be significantly limited, which is not in line with the low-carbon strategy.

[0007] In summary, the technical problems in the related art need to be improved. SUMMARY

[0056] The heat pump air conditioning module, the adsorption refrigeration air conditioning module, the power battery module, the motor thermal management module, the fuel cell thermal management module, and the heating and ventilation module are coupled through the central heat exchange module, the heat pump air conditioning module exchanges heat through a refrigerant (such as R134a, etc.), the power battery module, the motor thermal management module, and the fuel cell thermal management module all exchange heat through a cooling liquid (such as 50% ethylene glycol aqueous solution, etc.), and the adsorption refrigeration air conditioning module uses water as a heat exchange medium, specifically, the fluid input ends of the central heat exchange module are used to receive heat transfer media from the target modules, and the fluid output ends of the central heat exchange module are used to output the heat transfer media to the target modules.
