The underfloor air distribution (UFAD) system is widely used in the data center account for the potential of energy saving. However, the uneven distribution of airflow in the underfloor plenum will deteriorate the thermal environment of UFAD system and cause the uniform cooling for servers in the racks. To improve the cooling performance of UFAD system based data center, several kinds of underfloor vertical baffles (UVB) were designed and employed to guide airflow path. By using the computational fluid dynamics (CFD) model, the thermal environment of UFAD based data center had been significantly improved. The results show that the maximum temperature at the top of racks was reduced by about 8.5 °C by deploying the enclosed baffles. The average values of average inlet/outlet temperature were decreased by 4.15 and 3.03 °C, respectively, and the standard deviations of them were 8.8 and 19.3% of those in no-baffle model.
