摘要:

设计了一种采暖系统和一种结构合理的风道结构,达到了改善乘员舱热环境的目的。对采暖系统的结构参数进行优化设计,针对出风口倒角半径、风道轴线与X轴角度、出风口高度、回风口形式等四个因素,根据正交试验理论,确定出最优化设计方案,即出风口倒角半径为60mm,风道轴线与X轴之间的夹角为110°,出风口高度为570mm,回风口形式为Z-6-280×5。对最优化设计方案进行CFD数值模拟,同时监测驾驶员、乘员1、乘员2头部及脚部温度值,说明最优化设计方案的采暖系统对改善驾驶员、乘员1、乘员2乘坐热感觉起到了明显的作用。

Abstract:

A heating system and a reasonable structure of the air duct structure are designed, to achieve the purpose of improving the passenger compartment thermal environment. The structural parameters of the heating system are optimized. Aiming at the four factors such as the chamfer radius of the air outlet, the angle between duct axis and X axis, the height of the outlet and the type of return air grille on the thermal environment of passenger compartment, according to the orthogonal test theory, the optimal design scheme is determined, and the optimal design scheme is that the chamfer radius of the air outlet is 60mm, the angle between duct axis and X axis is 110°, the height of the outlet is 570mm, the type of return air grille is Z-6-280×5. The CFD simulation of the optimal design is carried out, the temperature of heads and feet of driver, passenger 1 and passenger 2 are monitored, the result show that the heating system of the optimal design can greatly improve the thermal sensation of driver, passenger 1 and passenger 2.
