摘要

为提升实车散热器的换热性能

在传统乘用车单风扇系统的基础上设计出5种风扇矩阵型式

利用数值仿真分析不同矩阵型式对散热器换热性能的影响

并提出差速控制策略

进一步优化车辆冷却前端换热。结果表明:不同矩阵风扇型式对散热器换热性能的影响不同

其中矩阵风扇(风扇数N=6)所实现的换热量最大

为最优的布置型式; 对于矩阵风扇(N=6)

当低温区风扇以较高转速运行时

能够减少怠速工况下车辆前端的热回流

降低发动机舱内部的平均温度

有效改善发动机舱的热环境; 同时在怠速工况下当转速比为3时

散热器换热量达到6.61 kW

相比匀速工况提高1.71%

而当车辆低速行驶且转速比为1.8时

散热器换热量为10.73 kW

相比匀速工况增加1.2%; 此外

低温区风扇以较高转速运行还能够抑制发动机舱内部及护板下方的流动分离

并降低车辆低速行驶时发动机舱内部流道的沿程阻力。

Abstract

To improve the heat dissipation performance of vehicle radiator

based on the single fan configuration of a traditional passenger car

this paper designs five different matrix fan configurations

and numerically analyzes of the effect of different configurations on the heat dissipation performance of radiator. With the differential control strategies introduced

a further optimization of the thermal management on the vehicle front end is conducted. The final results indicate that different matrix fan configurations have different effects on the heat dissipation performance of radiator

the matrix fan(N=6)is the optimal configuration due to the largest heat dissipation achieved. As the fans run in low-temperature region at higher speed

this matrix fan can decrease the hot air recirculation at idle and lower the average temperature in underhood

thus effectively improving the thermal environment of underhood. In the idle condition

when the rotation speed ratio α=3

the heat dissipation reaches 6.61 kW

which is improved by 1.71% compared with the uniform speed condition; and similarly

in the low-speed condition

when the rotation speed ratio α=1.8

the heat dissipation reaches 10.73 kW

which is improved by 1.2%. Moreover

the fans running in low-temperature region at higher speed also can suppress the flow separation in underhood and beneath the engine board

and decrease the flow resistance in underhood as the vehicle runs at a low speed.
