The utility model discloses a flow guide type automobile water pump water seal cooling mechanism. The flow guide type automobile water pump water seal cooling mechanism comprises a water pump shell, a water seal and an impeller, wherein the impeller consists of a wheel disc and blades; the wheel disc is provided with a flow guide hole. The flow guide hole is of a conical structure. A water inlet of the flow guide hole is larger than a water outlet of the flow guide hole. According to the cooling mechanism, the phenomenon of water shortage of the water seal caused by a centrifugal effect is solved according to the phenomenon that the pressures at different positions in the water pump are different, and an internal cycle in the water pump is realized; the cooling mechanism has a simple structure and is low in cost; the phenomenon of dry grinding of the water seal is prevented; the service life of the water seal is prolonged; the service life of the water pump is further prolonged; the technical problem of failu
