The present invention relates to an electric vacuum pump for a vehicle, and more specifically, relates to an electric vacuum pump for a vehicle, which is capable of using an air flow going into a pump chamber to improve a cooling performance of the pump. To achieve this, according to the present invention, the electric vacuum pump for the vehicle comprises: a pump housing including: a pump chamber which may accommodate a rotor inside; and a barrier rib which wraps around the pump chamber; a top plate placed on the pump housing to seal a top side of the pump chamber; a bottom plate placed on a bottom side of the pump housing to seal a bottom side of the pump chamber; an intake hole placed on the bottom plate; and a flow path formed on the barrier rib of the pump housing to make at least a part of air taken in through the intake hole flow before going into the pump chamber.

    본 발명은 차량용 전기식 진공 펌프에 관한 것으로서, 상세하게는 펌프 챔버로 유입되는 공기의 흐름을 이용하여 펌프의 냉각 성능을 개선시킬 수 있는 차량용 전기식 진공 펌프에 관한 것이다. 이러한 목적을 달성하기 위한 본 발명은, 내부에 로터가 수용될 수 있는 펌프 챔버 및 펌프 챔버를 둘러싸는 격벽을 포함하는 펌프 하우징과; 상기 펌프 하우징의 위에 배치되어 펌프 챔버의 상부를 밀폐하는 상부 플레이트와; 상기 펌프 하우징의 하부에 배치되어 펌프 챔버의 하부를 밀폐하는 하부 플레이트와; 상기 하부 플레이트에 마련되는 흡입구와; 상기 펌프 하우징의 격벽에 형성되고, 상기 흡입구를 통해서 흡입된 공기 중 적어도 일부가 펌프 챔버 내부로 유입되기 전에 유동할 수 있도록 마련되는 유동 유로를 포함하는 것을 특징으로 한다.
