Indirect contact liquid cooling system: heat is exchanged with the coolant inside the server in the heat exchanger outside the server through an intermediary fluid (such as fluorinated liquid), and then the intermediary fluid is transferred to the external cooling system.

  • Fengliu structure
  • Heat dissipation up to 12kW
  • PUE≤1.2
  • Plug-in frame design
  • Hot and cold aisle isolation
  • The heat dissipation is as high as 15kW, which can quickly complete the construction of edge computer rooms and the transformation of old computer rooms. Annual OUE≤1.2, heat exchange increased by 10%.
