Self-radiating electronic cooling water pump

Abstract

The invention provides a self-radiating electronic cooling water pump which comprises a volute component, a rotor impeller component, a stator component, a control circuit board, and an end cover; thestator component comprises a housing and a stator part; the inside of the housing is divided into two parts by a partition plate; one part is provided with the stator part; the inside of the housingcorresponding to the stator part is provided with a rotor accommodating cavity; the rotor impeller component comprises a rotor part and an impeller part; the impeller part is fixed to the rotor part;the rotor part is placed inside the rotor accommodating cavity; the volute component is sealed at the other end of the housing to form a space; the impeller part is partially placed inside the space;the other part is sealed by the end cover to form another space; the control circuit board is placed in another space; a waterproof cup is arranged inside the rotor accommodating cavity; the outer wall of the body of the waterproof cup clings to a stator; one end of a rotor shaft of the rotor part is fixed to the bottom of the waterproof cup; and the other end of the rotor shaft is connected within a hole of a volute. The self-radiating electronic cooling water pump has the advantages of simple structure and good cooling effect.

Description

technical field [0001] The invention relates to an electronic cooling water pump. Background technique [0002] The existing electronic cooling water pump generally includes a housing, a volute part, a motor including a stator rotor, an impeller, a control circuit board, and an end cover. The cover is sealed, the control circuit board is placed in the space sealed by the end cover, the motor and impeller are placed in the space sealed by the volute parts, and the control circuit is set in the control circuit board, and the temperature controlled by the control circuit in the control circuit board according to the required temperature And adjust the motor speed, so as to control the pump flow, so as to achieve the purpose of precise temperature control.

Problems solved by technology

[0003] In the existing electronic cooling water pump motor, parts made of thermoplastics are often used to separate the cooling liquid between the stator and the rotor. Large magnetic resistance makes the efficiency of the whole water pump low, and the thermal conductivity of the plastic is poor, which is also not conducive to the heat generated by the stator winding through the cooling liquid for heat dissipation. larger size and weight
