英文摘要：

The heat-generation model, heat-exchange model and 3D computational fluid dynamics （CFD） model for Ni/MH batteries are established with boundary conditions defined. Then the flow field and temperature field of cooling structure are analyzed and predicted with the factors affecting the unevenness of temperature field discussed. Finally through the simulation and structural optimization, a cooling structure scheme of Ni/MH batteries with good performance is proposed.
