Abstract

The invention provides a vehicle-mounted air conditioner duct design method based on CAE emulation technique. The method comprises a modeling procedure, an emulation analysis procedure, an air distribution and judgment procedure and an optimization procedure, wherein the optimization procedure means that one or more of multiple air duct optimization ways are adopted selectively to conduct optimization to an air duct three-dimensional model, the multiple air duct optimization ways comprise the steps of changing bending angles at one or more positions of one or more divergent air ducts; changing the cross sections at the one or more positions of the one or more divergent air ducts; arranging stream guidance structures used for reducing flow or draining flow at the upstream of air duct forks of the one or more divergent air ducts. By means of the design method, the problems that in the prior art, the cycle is long and the cost is high in the classified optimization of vehicle-mounted air conditioner ducts are effectively solved.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to a design method of a vehicle air-conditioning air duct based on CAE simulation technology. Background technique [0002] The vehicle air conditioner is closely related to the comfort of the occupants. It is responsible for defrosting, heating, cooling, ventilation and many other functions in the vehicle. It is one of the important indicators for evaluating comfort. [0003] 1. Cutting-edge air volume optimization ideas. [0004] To improve occupant comfort, the most important thing is to improve the performance of the air conditioner. As an important part of the car air conditioner, the air duct is difficult to design in place at one time. In the actual design and production process, there are cases where the air volume of some air outlets is too small or even no air flow. On the premise of excluding the lack of air volume of the air conditioner main unit, with the ra...
