The invention discloses an automobile electronic water pump comprising a metal pump shell and a pump head. A first chamber and a second chamber separated from the first chamber are arranged in the metal pump shell. A stator, a rotor and a shaft core are sequentially arranged inside the first chamber from outside to inside. A controller electrically connected with the stator is fixedly arranged in the second chamber. The automobile electronic water pump is characterized in that a metal separation plate is arranged between the first chamber and the second chamber, the controller is fixedly arranged on the metal separation plate, and an insulating thermal conductive adhesive is arranged between the controller and the metal separation plate. The automobile electronic water pump has the advantages that heat generated by the controller can be transmitted onto the metal separation plate through the insulating thermal conductive adhesive in time, the heat is rapidly dissipated through the metal separation plate, the heat of the controller and the second chamber where the controller is located is brought away, the highest using temperature of the automobile electronic water pump is greatly increased, and thus the performance of an electric automobile is improved.
