【摘要】：基于熱力學(xué)理論并運用Hyper Works分別對矩形翅片散熱器和環(huán)形翅片散熱器進行穩(wěn)態(tài)熱仿真分析,優(yōu)選出散熱性能較好的翅片散熱器。為了改善空調(diào)散熱器的散熱性能,本文對優(yōu)選的翅片散熱器進行基于形狀優(yōu)化的穩(wěn)態(tài)熱傳導(dǎo)和固有頻率分析。采用Hyper Morph對優(yōu)選的翅片散熱器進行預(yù)變形定義并作為形狀優(yōu)化的設(shè)計變量,通過Opti Struct求解器計算出使散熱性能最優(yōu)的翅片散熱器結(jié)構(gòu)形狀和固有頻率。該方法有效地降低空調(diào)散熱器最高溫度并改善了它的散熱性能,還大大地提升了空調(diào)散熱器的抑制振動能力。
[Abstract]:Based on thermodynamics theory and Hyper Works, the steady state thermal simulation analysis of rectangular fin radiator and annular fin radiator is carried out, and the finned radiator with better heat dissipation performance is selected. In order to improve the heat dissipation performance of air conditioning radiator, the optimal finned fin radiator is analyzed based on shape optimization of steady state heat conduction and natural frequency. Hyper Morph is used to define the predeformation of the finned fin radiator and as a design variable for shape optimization. The structure shape and natural frequency of the fin radiator with optimum heat dissipation performance are calculated by Opti Struct solver. This method can effectively reduce the maximum temperature of air conditioning radiator, improve its heat dissipation performance, and greatly improve the vibration suppression ability of air conditioning radiator.
