摘要
针对高频手术电刀工作腔体在高温环境下的性能优化,提出一种基于热载荷分析与热力耦合建模的结构优化方法。通过优化电极接触面形状、冷却系统流道几何和密封区域设计,显著降低了腔体的最大温升、热应力和密封间隙变化。实验与仿真结果表明,优化后的设计有效提高了腔体的温控、热管理效率及密封性能,提升了设备在高温工况下的长期稳定性和安全性。
To improve the performance of the working cavity in high-frequency electrosurgical devices under high-temperature conditions,a structural optimization method based on thermal load analysis and thermo-mechanical coupling modeling is proposed.By optimizing the electrode contact geometry,cooling channel design,and sealing structure,the maximum temperature rise,thermal stress,and sealing gap variation are significantly reduced.Experimental and simulation results demonstrate that the optimized design effectively enhances thermal control,heat management efficiency,and sealing performance,thereby improving the long-term stability and safety of the device under high-temperature operating conditions.
