A cooling system includes a cooling loop, a cooling branch, and a refrigerant. The cooling loop includes a condenser, a first valve, an evaporator, and a compressor etc. connected to form a loop. The cooling branch is configured in parallel with the evaporator, the cooling branch includes a cooling unit with thermal contact with one or more to-be-cooled components through a thermal interfacial material. The refrigerant flows through the cooling unit with a phase change process to cool components and the flow rate is optimized for energy efficiency purpose. A traditional cooling branch featured by heat exchanger & pump with a separate coolant is not required, which reduces the cost, improves the space utilization and boosts efficient cooling of components in e-vehicles, especially autonomous ones, with sufficient cooling capability and minimized cooling delay.
