Analysis of Cooling Capacity of Backplane Air-cooled Rack

Backplane air conditioner cooling solves the heat dissipation problem inside a rack, which can reduce the waste of cooling capacity and significantly improve refrigeration efficiency. To explore the cooling capacity of a backplane air-cooled rack under different working conditions, a rack model was...

description Backplane air conditioner cooling solves the heat dissipation problem inside a rack, which can reduce the waste of cooling capacity and significantly improve refrigeration efficiency. To explore the cooling capacity of a backplane air-cooled rack under different working conditions, a rack model was established using CFD simulation software to simulate the thermal environment of the rack. The results showed that the air distribution inside the rack was good, and there was no mixing of cold and hot air. The server temperature decreased with an increase in the circulating air volumetric flow rate, and the decreasing trend saturated at higher flow rates. As the inlet air temperature increased, the server temperature increased linearly. When the inlet air temperature was 18, 20, 22, 24, and 26 °C, by changing the total circulating air volumetric flow rate changed within the range of 2 400–3 200 m3/h, the maximum load power range of a 42U rack was 11.7–15.0 kW, 11.2–14.5 kW, 10.8–14.0 kW, 10.3–13.4 kW and 9.8–12.7 kW.
