Abstract

In this paper, the principle of heat dissipation for power module of electric air conditioner is analyzed mathmatically, and the method of optimizing the heat dissipation structure is proposed. The thermal analysis model of the power module is built by the finite element method. Simulation results show that the proposed method can optimize the thermal performance of the power module, extend the life cycle of the power module and increase the reliability of the system.

Abstract

This paper proposes a novel integrated magnetic-geared machine for low-speed large-torque applications. By embedding the armature windings into the air slots adjacent to the modulating segments, a complex component which can serve as the armature stator and the modulating stator simultaneously is achieved. Therefore, the proposed integrated machine is with simpler mechanical structure than the existing integrated machine. Since the permanent magnets on the two rotors are all effectively involved in the energy conversion process, high torque density can be achieved. Moreover, the proposed machine exhibits high power factor due to the week armature-excited field. [ABSTRACT FROM PUBLISHER]
