The present invention relates to a cooling system for an electric vehicle. The purpose of the present invention is to provide a cooling system for an electric vehicle that can reduce coolant well resistance and flow resistance, can increase the total coolant flow rate, and can improve cooling performance. In order to achieve the above purpose, disclosed is a cooling system for an electric vehicle, wherein a coolant line through which coolant circulates includes: a main coolant line having a radiator installed thereon, and a first branch coolant line and a second branch coolant line branching off in parallel to be connected to the main coolant line, wherein components to be cooled are installed on the first branch coolant line and the second branch coolant line so that the coolant can pass therethrough, and wherein an electromotive water pump includes a first pump installed on the main coolant line and having the operation thereof controlled by a controller, and a second pump installed on either the first branch coolant line or the second branch coolant line and having the operation thereof controlled by the controller.

    본 발명은 전기자동차의 냉각 시스템에 관한 것으로서, 냉각수 통수 저항 및 유동 저항을 줄일 수 있고, 전체 냉각수 유량 증대 및 냉각 성능 향상이 가능해지는 전기자동차의 냉각 시스템을 제공하는데 그 목적이 있다. 상기한 목적을 달성하기 위해, 냉각수가 순환하는 냉각수 라인이, 라디에이터가 설치된 메인 냉각수 라인, 및 상기 메인 냉각수 라인에 병렬로 분기되어 연결된 제1 분기 냉각수 라인과 제2 분기 냉각수 라인을 포함하고, 상기 제1 분기 냉각수 라인과 제2 분기 냉각수 라인에 각각 냉각수가 통과하도록 냉각 대상 부품이 설치되며, 전동식 워터펌프는, 상기 메인 냉각수 라인에 설치되고 제어기에 의해 구동이 제어되는 제1 펌프, 및 상기 제1 분기 냉각수 라인과 제2 분기 냉각수 라인 중 하나에 설치되고 제어기에 의해 구동이 제어되는 제2 펌프를 포함하는 전기자동차의 냉각 시스템이 개시된다.
