Working fluid medium temperature control system and method

摘要

A working fluid medium temperature control system comprises an actuator (80) operable on a working fluid medium, a pump (60) for the working fluid medium, a fluid passage structure (66) for the working fluid medium, an electric motor (50) drivingly connected to the pump (60), and a control unit (40) for the electric motor (50), the control unit (40) including an inverter (42) and an inverter controller (41). The inverter (42) and the electric motor (50) are integrated in such a way that the inverter (42) is in heat transfer communication with the electric motor (50). The fluid passage structure (66) is in heat transfer communication with the inverter (42).
