摘要
在传热学的理论基础上,利用CFD软件Fluent,分析了某大功率Boost型DC/DC变换器的散热系统,建立了它的热模型,并对其进行水冷散热仿真。分析和比较通过不同水冷热设计参数得到的仿真结果,提出了改善DC/DC变换器散热特性的措施,达到提高其工作可靠性的目的,减小了散热设备所需的空间。
Based on the theory of heat transfer, the heat dissipation system of a high-power Boost type DC/DC converter is analysed by using CFD software Fluent. The thermal model is established and its cooling simulation is carried out. Through the analysis and comparison of different design parameters of water-cooled plate obtained simulation results, proposed the improvement for heat dissipation characteristics of DC/DC transform measures to improve the working reliability of the equipment, reduces the cooling space required.
