【摘要】：以某雷达天线单元为研究对象,采用Icepak热仿真软件,研究了风腔厚度对强迫风冷系统散热性能的影响。结果表明:风腔厚度对风冷系统的散热性能有明显影响;保持风机型号和散热器结构不变,当风腔厚度过小时,风机的性能受到明显抑制;随着风腔厚度的增加,风机的性能会变好,发热元件的温度明显降低;当风腔厚度达到一定值后再继续增加时,风机的性能反而会下降,发热元件的温度也相应升高。在工程设计中,推荐此类风冷散热结构的风腔厚度取值不小于16mm,不大于40mm。
[Abstract]:Taking a radar antenna unit as the research object, the effect of the thickness of the air chamber on the heat dissipation performance of the forced air cooling system is studied by using the Icepak thermal simulation software.The results show that the thickness of the air chamber has a significant effect on the cooling performance of the air cooling system, while keeping the type of fan and the structure of the radiator unchanged, when the thickness of the air chamber is too small, the performance of the fan is obviously suppressed; with the increase of the thickness of the air chamber,The performance of the fan will become better and the temperature of the heating element will obviously decrease, and when the thickness of the air chamber reaches a certain value and then continues to increase, the performance of the fan will decrease and the temperature of the heating element will rise accordingly.In the engineering design, it is recommended that the thickness of the air chamber of this kind of air-cooled heat dissipation structure is not less than 16mm and not more than 40mm.
