N2 - In this study, servers are equipped with terminal baffles to optimize the thermal environment within data center and achieve energy conservation. The data center model is established by Airpak 3.0 packages based on an actual running data center. In the original model, the rack with the highest heat load (16.98 kW) is selected as the research object, while the exhaust airflow distribution of that rack is obtained. In order to optimize the exhaust airflow distribution, the optimization models with 8-cm baffles and six different baffle angles (0°, 15°, 30°, 45°, 60°, 75°) are established based on the original model. The results show that, although the use of 0° server baffles deteriorates the thermal environment, airflow distribution and cooling efficiency are improved to varying degrees when the inclination angle of the 8-cm baffles increases from 15 to 75°. The optimum thermal environment is achieved when the baffle angle is 45°. Under this circumstance, the maximum drop of rack hotspots reaches 2.5 °C.
