Title: Container of cloud computing system

Description:
BACKGROUND  
     1. Technical Field 
     The disclosure generally relates to containers of containing cloud computing systems, particularly to such a container of a cloud computing system with a ventilation system. 
     2. Description of Related Art 
     A cloud computing system typically includes a container and servers positioned in the container. To cool the servers in the container, the container generally includes a ventilation system used to draw exterior cool air into the container through an airflow inlet, and hot air in the container is vented out via an airflow outlet of the ventilation system. However, after a long-term use, a lot of dust may be accumulated at the airflow inlet, which is an adverse affect for cooling effect in the container. 
     Therefore, there is room for improvement within the art. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary container of a cloud computing system. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment. 
       FIGURE is a schematic view of an embodiment of a container of a cloud computing system. 
     
    
    
     DETAILED DESCRIPTION 
     Referring to the FIGURE, a container  10  of a cloud computing system includes a housing  11 , a controlling device  14  and a fan assembly  15  mounted to the housing  11 . 
     The housing  11  includes a lower board  117 , an upper board  111  opposite to the lower board  117 , and a side board  112  connecting the lower board  117  and the upper board  111 . The lower board  117 , upper board  111  and side board  112  cooperatively form a chamber  12 , in which the controlling device  14  is received. An airflow outlet  113  is defined through the upper board  111  and communicates with the chamber  12 . A dust strainer  115  covers the airflow outlet  113  to prevent impurities, such as dust, from entering into the chamber  12 . A plurality of airflow inlets  114  are defined through the side board  112  and communicate with the chamber  12 . 
     The fan assembly  15  includes a plurality of fans  16  equal to the airflow inlets  114 . Each fan  16  is fixed in one of the airflow inlets  114 . A plurality of dust gauzes  116  cover the airflow inlets  114  to prevent impurities, such as dust, from entering into the chamber  12 . The fans  16  can rotate clockwise or counter-clockwise under a control of the controlling device  14 . When the fans  16  rotate clockwise, the fans assembly  15  draws exterior cool air into the chamber  12  through the airflow inlets  114  and force the exterior cool air to flow to electronic devices inside the chamber  12 , such as the controlling device  14 , which are cooled. Hot air in the chamber  12  then vents out of the chamber  12  via the airflow outlet  113 . When the fans  16  rotate counter-clockwise, the fans assembly  15  exhausts the air in the chamber  12  via the airflow inlets  114  to clear dust on the dust gauzes  116 . 
     One example of cooling the chamber  12  is taken below. After the fans  16  all rotate clockwise to draw exterior cool air into the chamber  12  via the airflow inlets  114  to cooling the chamber  12  for a first determined period (e.g., about 60 minutes), the fans  16  all rotate counter-clockwise to draw air in the chamber  12  out of the chamber  12  via the airflow inlets  114  for a second determined period (e.g., about 1 minute), the air from the chamber  12  blows to the dust gauzes  116 , and the dust accumulated on the dust gauzes  116  is cleared. 
     Another example of cooling the chamber  12  is taken below. After the fans  16  all rotate clockwise to draw exterior cool air into the chamber  12  to cooling the chamber  12  for the first determined period (e.g., about  60  minutes), at least one of the fans  16  rotates counter-clockwise to clear the dust on the dust gauze  116  corresponding to the at least one of the fans  16  for the second determined period (e.g., about 1 minute), simultaneously, the other fans  16  continue to rotate clockwise to cooling the chamber  12 . 
     It is to be understood, however, that even through numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
