Abstract

A thermal management system of a ship composite energy power system and a control method thereof are provided, including a thermal management circuit, which includes a seawater heat exchange circuit, an internal combustion engine thermal management circuit, a hydrogen fuel cell thermal management circuit, and a power battery and accessories thermal management circuit. It provides a thermal management control strategy for composite energy of internal combustion engine, fuel cell, and power battery; the various circuits can be independently adjusted; the heat dissipation effect is obvious, and the temperature of each cooling circuit can be better controlled; the energy utilization rate can be improved; the heat can be transferred to the other subsystems, and the heat dissipation area can be enlarged; and the fuel cell circuit can be elevated to the temperature by the heat exchanger and the electric heater, and it can reach the target working temperature more quickly.
