| 摘要: |
| 采用FLUENT软件,对不同环境温度和充放电倍率时,两种双口出风模式电动汽车动力舱自然进风散热进行研究,结果表明:电动汽车动力舱自然进风散热性能随着车速提高而改善,电池组最高温升曲线的斜率明显高于内部最大温差,表明高速气流更有利于电池组内部温度降低;不同环境温度和充放电倍率下,双口上出风口模式的电池组最高温升和内部最大温差均低于两边出风口模式,可见将两边出风口模式改为双口上出风口模式,电动汽车动力舱自然进风散热性能将得到改善． |

| Abstract: |
| By software FLUENT, the influence of different double-outlet mode of wind on the electric vehicle power cabin natural wind cooling performance with different environmental temperature and charge ＆ discharge rate is researched, and the results show that the heat dissipation performance of electric vehicle power cabin natural wind cooling is improved as the vehicle speed is increased, the heat dissipation performance of up-outlet mode of wind with two hole is better than both sides outlet mode in all fields of different environmental temperature and charge ＆ discharge rate. |
