摘要/Abstract

摘要： 为了提升电动汽车控制器可靠性与经济性,对控制器冷却系统进行改进优化。建立简化的等效仿真模型,根据流体能量耗散公式、壳体散热公式进行针对性优化,得出最适合的结构搭配。与原方案相较,实现流阻、温升双降低,为后续同类产品设计、优化工作提供了案例。

Abstract: In order to improve the reliability and economy of the electric vehicle controller, the controller cooling systemwas improved and optimized. A simplified simnlation model was establish, according to the fluid energy dissipation formula, shell cooling formula for targeted optimization, the most suitable structural matching was reached. The optionization was achieve flow resistance and temperature rise double reduction compared with the original scheme, it is provided for the follow-up similar product design, optimization work.

Key words: electric vehicle controller, cooling waterway, flow resistance, temperature rise
