Engine electric water pump and vehicle having same

Abstract

The invention discloses an engine electric water pump and a vehicle with the same. The engine electric water pump comprises a water pump bracket and a water pump body; the water pump body includes a water pump shell, a water pump end cover, a driving assembly, a stator, fixed shafts, a rotor and an impeller; the water pump shell and the water pump end cover form a control room; a rotor chamber is formed in one side, far from the water pump shell, of the water pump end cover; one side, far from the water pump shell, of the water pump end cover and the water pump bracket form a spiral room; a recess part is communicated with the spiral room, but not communicated with the control room; the spiral room is communicated with the internal of the water pump bracket through a cooling liquid inlet and a cooling liquid outlet; the fixed shafts are fixed in a rotor room and the spiral room; the rotor is arranged in the rotor room; the impeller is arranged in the spiral room, is fixed on the rotor, and can rotationally coat the fixed shaft around the fixed shaft; and the stator coats the outer side wall of the rotor room. The engine electric water pump can realize the flow adjustment of cooling liquid under all working conditions of an engine, and can improve the efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to an engine electric water pump and a vehicle with the engine electric water pump. Background technique [0002] The water pump is an indispensable component in the engine cooling system. It mainly provides kinetic energy for the coolant to make the coolant flow in the engine cooling system, so that the coolant can take away the heat generated in the engine system in time. [0003] In the prior art, traditional vehicles basically use mechanical water pumps. The mechanical water pumps are driven by an accessory gear train on the engine. The water pump is directly proportional to the rotational speed of the engine, but has nothing to do with the load of the engine. Since the performance of the water pump is based on ensuring that the engine does not overheat, it is usually necessary to linearize the performance based on the highest temperature point of the vehicle or the highes...

AI Technical Summary

Problems solved by technology

The impeller of the independent electric water pump is built-in, and the independent electric water pump is closed as a whole. It is necessary to introduce part of the coolant into the motor for heat dissipation. The coolant is introduced into the motor. When the power of the electric water pump is constant, the pump output will be reduced. coolant flow
