The invention discloses a distributed electrically-driven cooling system, which comprises a first cooling link and a second cooling link, and is characterized in that the first cooling link comprises a first pump, a first heat exchanger and a first motor branch; the second cooling link comprises a second pump, a second heat exchanger and a second motor branch; a connecting pipeline is arranged between the first motor branch and the second motor branch, and a second valve is arranged on the connecting pipeline; wherein the first heat exchanger, the second heat exchanger and the first valve are arranged on a whole vehicle heat exchange pipeline, the first heat exchanger or the second heat exchanger is connected with the first valve, and the first valve determines whether to participate in heat exchange or not. By arranging the first pump, the second pump, the first valve and the second valve, the cooling requirement of the cooling system when the motor is in different working modes is met, the energy consumption of the pumps is reduced, the cooling efficiency of the cooling system is improved, and redundant control of the pumps is achieved.

    本发明公开了一种分布式电驱动的冷却系统,包括第一冷却链路和第二冷却链路,所述第一冷却链路包括第一泵、第一换热器和第一电机支路;所述第二冷却链路包括第二泵、第二换热器和第二电机支路;所述第一电机支路和第二电机支路之间设置有连接管路,所述连接管路上设置有第二阀;其中,第一换热器、第二换热器和第一阀设置在整车换热管路上,且所述第一换热器或者第二换热器与第一阀连接,由所述第一阀决定是否参与换热。本发明通过设置第一泵、第二泵、第一阀和第二阀满足了冷却系统在电机处于不同工作模式下的冷却需求,且降低了泵的能耗,提高了冷却系统的冷却效率,且实现了泵的冗余控制。
