The finite time thermodynamic analysis,the exergy method were employed to build the simulation model of the combined system of water cooled multi-spilit heat pipe system(MSHPS)used in data center.The results show that the IT servers should concentrate on arranging at the location below 1.3 m.The CDU has a heat transfer of about 74 J in a period of 6 s.And the optimum flow rate of the CDU is 0.82 kg/s.Then the free cooling time,part time free cooling and energy saving potential in major cities of China were analysised.The energy saving potential is from 61％to 25％.The results are of great significance for the operational control and practical application of other pipe-net systems.
