Data center and heat dissipating system thereof

Abstract

A container data center includes a plurality of server systems installed in a container. Each server system includes a power distribution units (PDU) used to manage power and a heat dissipating system to dissipate heat. The heat dissipating system includes a fan and a fan controller connected to the PDU. The PDU detects output power of the corresponding server system and transforms the output power to a corresponding fan rotation speed control signal transmitted to the fan controller, the fan controller controls rotation speed of the fan according to the fan rotation speed control signal.

1 . A data center comprising:
 a portable container; and   a plurality of server systems installed in the container, wherein each of the plurality of server systems comprises a power distribution units (PDU) to manage power, and a heat dissipating system to dissipate heat;   wherein the heat dissipating system comprises a fan and a fan controller connected to the PDU, the PDU detects output power of the corresponding server system and transforms the output power to a corresponding fan rotation speed control signal to the fan controller, the fan controller controls rotation speed of the fan according to the fan rotation speed control signal.   
     
     
         2 . The data center of  claim 1 , wherein each of the plurality of server systems further comprises two racks and a plurality of servers arranged on the two racks. 
     
     
         3 . The data center of  claim 1 , wherein two fans of two adjacent server systems of the plurality of server systems are arranged on tops of the two adjacent server systems and blow down, two heat exchangers are respectively arranged on tops of the two adjacent server systems, the two heat exchangers cool hot air from two sides of the two adjacent server systems and the cooled air is blown into a space between the two adjacent server systems by the two fans. 
     
     
         4 . The data center of  claim 3 , wherein two heat insulation boards are arranged between the two heat exchangers and the two adjacent server systems, an opening is defined between the two heat insulation boards and located under the two fans, the two heat insulation boards insulate cooled air from heated air. 
     
     
         5 . The data center of  claim 3 , wherein the heat exchangers contain cold water. 
     
     
         6 . The data center of  claim 1 , wherein the fan rotation speed control signal is a pulse-width modulation signal. 
     
     
         7 . A heat dissipating system used to dissipate heat for a server system comprising a power distribution units (PDU) used to manage power, the heat dissipating system comprising:
 a fan; and   a fan controller connected to the PDU, the PDU detects output power of the corresponding server system and transforms the output power to a corresponding fan rotation speed control signal to the fan controller, the fan controller controls rotation speed of the fan according to the fan rotation speed control signal.   
     
     
         8 . The heat dissipating system of  claim 7 , wherein the fan rotation speed control signal is a pulse-width modulation signal.
