基于CFD的曲通管电加热结构优化

Optimization of Electric Heating Structure of Flexible Tube Based on CFD

文章以整车高寒工况下曲轴箱通风管口结冰问题布置的PTC电加热单元为研究对象,通过对比不同电加热单元布置结构下窜气气流温度和电加热单元温度,得出整车在极寒高速工况下受进气气流影响更小,在使用相同加热功率条件下加热曲轴箱通风管管口效果最优的布置结构。

In this paper,the PTC electric heating unit is designed to solve the freezing problem of the blowby pipeline under the vehicle cold working condition.Under the same heating power,through the comparison of the blowby-air temperature and the temperature of the electric heating unit,the optimal layout scheme of electric heating is obtained under the condition of extremely cold and high speed,which is less affected by the inlet air flow.
