Document Type and Number:
WIPO Patent Application WO/2019/187476
Kind Code:
A1
Abstract:
One aspect of the present invention relates to an electric pump, and the electric pump is provided with: a first pump chamber that pumps a first cooling medium using a first rotor; a second pump chamber that is disposed in parallel with the first pump chamber in the axial direction of the axis of rotation of the first rotor and that pumps a second cooling medium using a second rotor having an axis of rotation which is coaxial with the axis of rotation of the first rotor; a power chamber that is disposed in parallel with the second pump chamber in the axial direction and that is provided with an electric motor that can supply power to both the first and second rotors using a shared shaft; and a heat exchanger that is disposed between the first and second pump chambers and that exchanges heat between the first and second cooling medium. Consequently, cooling efficiency can be improved with a relatively simple configuration in an electric pump provided with pump chambers of two types.
