Heat dissipating system for data center

A heat dissipating system for a data center, the heat dissipating comprising:

• a return air area defining a return air damper and an air outlet;
• and
• an installation area defining an air inlet damper and an air outlet damper, the installation area comprising:
• a fan control unit configured to control heat dissipation from the electronic device in the data center;
• a humidity control unit configured to detect a humidity in the data center and controls the air inlet damper, the air outlet damper and the return air damper to open or close based on the humidity;
• and
• an electronic device;
• wherein outside air is configured to flow into the installation area through the air inlet damper, and warmed air generated by the data center is exhausted from out the data center through the air outlet damper;
• wherein in event that the humidity control unit detects that the humidity value in the installation area is greater than a standard value, the humidity control unit controls the return air damper to partly open, so that warmed air generated by the electronic device partly flows the return air area through the return air damper, the outside air and the warmed air from the return air area generated by the electronic device are mixed, the mixed air is configured to dissipate heat from the electronic device, whereby the humidity in the data center is reduced.
