Data center and heat dissipating control system thereof

Abstract

A data center includes a portable container, a number of server systems, and a number of nozzles. The server systems are installed in the container. Two opposite sides of each server system are respectively a hot aisle and a cold aisle. The nozzles are arranged in the ground under the cold aisles to supply cold airflow. The nozzles of each cold aisle are arranged in a number of rows parallel to two adjacent server systems. Heights of the cold airflow from the nozzles of each cold aisle form a step mode from the two adjacent server systems to the middle of the corresponding cold aisle.

What is claimed is: 
     
         1 . A data center comprising:
 a portable container;   a plurality of server systems installed in the container, wherein two opposite sides of each of the plurality of server systems respectively has a hot aisle and a cold aisle; and   a plurality of nozzles arranged in the ground under the cold aisles to supply cold airflow to the cold aisles, wherein the nozzles of each of the cold aisles are arranged in a plurality of rows parallel to two corresponding adjacent server systems, heights of the cold airflow from the nozzles of each of the cold aisles form a step mode from the two adjacent server systems to the middle of the corresponding cold aisle.   
     
     
         2 . The data center of  claim 1 , wherein each of the plurality of nozzles is a hollow circular truncated cone, an upper opening of each of the plurality of nozzles is an airflow outlet and a lower opening of each of the plurality of nozzles is an airflow intake. 
     
     
         3 . The data center of  claim 2 , wherein a height h of the cold airflow from one of the plurality of nozzles is adjusted by the following formula: h=(V1*A1/A2) 2 /2g, where V1 is an initial speed of the cold airflow at the airflow outlet, A1 is an area of the airflow outlet, A2 is an area of the airflow intake, g is the acceleration of gravity. 
     
     
         4 . A heat dissipating control system used to dissipate heat for a server system, the heat dissipating control system comprising:
 a plurality of nozzles arranged in the ground of one side of the server system, to supply cold airflow to the side of the sever system;   wherein the plurality of nozzles are arranged in a plurality of rows parallel to the server system, heights of the cold airflow from the plurality of nozzles form a step mode from the server system.   
     
     
         5 . The heat dissipating control system of  claim 4 , wherein each of the plurality of nozzles is a hollow circular truncated cone, an upper opening of each of the plurality of nozzles is an airflow outlet and a lower opening of each of the plurality of nozzles is an airflow intake. 
     
     
         6 . The heat dissipating control system of  claim 5 , wherein a height h of the cold airflow from one of the plurality of nozzles is adjusted by the following formula: h=(V1*A1/A2) 2 /2g, where V1 is an initial speed of the cold airflow at the airflow outlet, A1 is an area of the airflow outlet, A2 is an area of the airflow intake, g is the acceleration of gravity.
