Title:
ELECTRONIC OIL PUMP
Document Type and Number:
WIPO Patent Application WO/2022/057784
Kind Code:
A1
Abstract:
An electronic oil pump (100), comprising a first rotor assembly (2), a stator assembly (4), an electric control board assembly (6), an isolation member (5) and thermal conductive members (9); the first rotor assembly (2) is located in a first chamber (70) of the electronic oil pump (100), the thermal conductive members (9) each comprise a first portion (91) and a second portion (92), the first portions (91) being located in a second chamber (80) of the electronic oil pump (100), the second portions (92) being located in a third chamber (90) of the electronic oil pump (100); the electric control board assembly (6) comprises a base plate (61) and a temperature-sensing unit (13), the base plate (61) comprising first holes (611), an upper plate layer (612), a lower plate layer (613) and at least one metal layer (614), a part of the second portions (612) being located in the first holes (611); the temperature-sensing unit (13) is located at one side of the second portion (92), there is a preset distance between the temperature-sensing unit (13) and the second portion (92); the metal layer (614) closest to the temperature-sensing unit (13) is defined as the closest metal layer (6141), the temperature-sensing unit (13) is projected on the direction parallel to the upper surface of the closest metal layer (6141), at least a part of the projection of the temperature-sensing unit (13) is located on the closest metal layer (6141), the temperature-sensing unit (13) can sense the temperature of the closest metal layer (6141), or the temperature-sensing unit (13) can sense the temperature of the upper plate layer (612) or the lower plate layer (613) in contact with the closest metal layer (6141).
