摘要

提出了一种用于直线同步电机的多通道液冷板结构。首先，建立了耦合散热模型，采用有限体积法对不同通道数和截面形状下的流体场和温度场进行了耦合分析。仿真结果表明，该冷却板的冷却能力有明显提高，特别是对于椭圆截面的6通道冷却板。随后，采用二次逼近算法进行边界优化，进一步优化椭圆截面6通道板的截面尺寸，实现传热系数和泵功率的权衡。与原方案相比，优化后的换热系数提高33.03%，压降降低85.37%。

Thermodynamic analysis and optimization design of cooling plate with multiple channels for linear synchronous motor

A liquid cooling plate structure with multiple channels is proposed for linear synchronous motor in this paper. Firstly, a conjugate heat dissipation model is established, and coupling analysis with fluid and temperature fields is performed by finite volume method with different channel numbers and section shapes. The simulation results show that, the cooling capacity of proposed cooling plate is observably improved, especially for 6-channels cooling plate with elliptical section. Afterwards, adopting boundary optimization by quadratic approximation algorithm, the section dimensions of 6-channels plate with elliptical section are further optimized to realize a trade-off with heat transfer coefficient and pump power. The optimized scheme can improve heat transfer coefficient by 33.03% and reduce the pressure drop by 85.37% compared with original scheme.

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
