摘 要：隨著汽車行業(yè)的競爭不斷激烈，空調系統(tǒng)逐漸得到重視。更好的空調系統(tǒng)能給乘員艙提高更舒適的駕駛環(huán)境，進而提高產品在同行業(yè)中的競爭力。而在空調系統(tǒng)當中，風道和出風口做為重要的組成部件，它們的性能優(yōu)劣直接影響乘員艙內的環(huán)境溫度與感官舒適性。本文以SGMW某車型為例，通過STAR-CCM+軟件模擬出空調系統(tǒng)的速度場，分析風道和出風口造型對空調出風性能的影響，并通過優(yōu)化風道和出風口造型提升空調吹面性能。

關鍵詞：CFD仿真 出風口 風道 乘員艙舒適性

The CFD Simulation Method of Optimizing the Shape to Improve the Air Conditioning Outlet Performance

Zhao Huifang Yang Li Peng jing Duan Dalu

Abstract：With the increasingly fierce competition in the automotive industry， air conditioning systems have gradually gained attention. A better air conditioning system can improve a more comfortable driving environment for the passenger compartment， thereby increasing the competitiveness of the product in the same industry. In the air conditioning system， air ducts and air outlets are important components， and their performance directly affects the ambient temperature and human comfort in the passenger compartment. Taking a SGMW model as an example， this paper simulates the speed field of the air conditioning system through STAR-CCM+ software， analyzes the influence of the air duct and air outlet shape on the air blowing performance of the air conditioner， and improves the air blowing performance by optimizing the air duct and air outlet shape.
