Flow distribution characteristic of parallel water-cooled heat sink applied in data center
To study the flow distribution characteristic of parallel water-cooled heatsinks applied in data center,the physical model is established.The optimal aperture ratio is discussed under different operating conditions,including volume flow rate,branch pipe spacing,and number of branch pipe.Simulation results show that,the increase of aperture ratio is conducive to the uniformity of flow distribution.The optimal aperture ratio is 3.2 when the total mass flow ranges from 1.5 to 7.5 L/min.Moreover,the branch pipe spacing also have the influence on the flow distribution.The uniformity of flow distribution became worse with the increase of mass flow.In addition,the optimal aperture ratio increases with the increase of number of branch pipes.With a branch pipe spacing of 150.0 mm and 5,10,and 15 branch pipes,the optimal aperture ratios are 3.2,5.0 and 6.0.A formula correlating the optimal aperture ratio with branch pipe spacing for practical engineering application is fitted.
