摘要
以某厂房的液冷机散热系统为研究对象,针对室外机在夏季高温期间回风温度过高的问题,利用计算流体力学(CFD)技术研究室外机与墙体之间的气流分布,并模拟安装导流风管对液冷机回风温度分布的影响。结果表明:未安装导流风管时,由于墙体对排风射流的遮挡,形成了大面积的高温回流,致使风温度显著升高;安装导流风管后,热风通过风管排出,提高了排热风的扩散效果,避免了热风直接吹向墙体形成高温回流,从而获得了最佳的回风温度。
Taking the cooling system of a liquid cooling machine in a certain factory building as the research object,in order to address the problem of high return air temperature of outdoor units during high temperatures in summer,computational fluid dynamics technology is used to study the airflow distribution between the outdoor unit and the wall,and simulate the effect of installing guide air ducts on the return air temperature distribution of the liquid cooling machine.The research results show that when the diversion duct is not installed,due to the obstruction of the exhaust jet by the wall,a large area of high-temperature backflow is formed,resulting in a significant increase in the return air temperature;After installing the diversion duct,the hot air is discharged through the duct,which improves the diffusion effect of the exhaust hot air and avoids the direct blowing of hot air towards the wall to form high-temperature backflow,thus obtaining the optimal return air temperature.
