Title: Fire suppression apparatus and container data center including same

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a fire suppression apparatus and a container data center including the fire suppression apparatus. 
     2. Description of Related Art 
     When a container data center is on fire, users usually enter the container data center to put the fire out with a hand-held fire extinguisher. However, it is dangerous for the user to enter the container data center during a fire. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
       Many aspects of the present embodiments can be better understood with reference to the following drawing. The components in the drawing are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawing, all the views are schematic, and like reference numerals designate corresponding parts throughout. 
       The figure is a block diagram of an exemplary embodiment of a fire suppression apparatus. 
     
    
    
     DETAILED DESCRIPTION 
     The disclosure, including the accompanying drawing, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
     Referring to the figure, an exemplary embodiment of a fire suppression apparatus  100  includes at least one fire detector  10 , a controller  20 , a flame retardant gas source  30 , a valve  40 , and a nozzle  50 . The fire suppression apparatus  100  is mounted in a container data center. 
     The fire detector  10  may be an arcing detector, a temperature detector, or a smoke detector. The arcing detector detects arcing light when electric apparatus in the container data center is shorted. The temperature detector detects the temperature in the container data center and the rising rate of the temperature in the container data center. The smoke detector detects the smoke density in the container data center. 
     An input DI 1  of the controller  20  is connected to the fire detector  10 . An output DO 1  of the controller  20  is connected to a control terminal C of the valve  40 . 
     An input DI 2  of the valve  40  is connected to the flame retardant gas source  30 . An output DO 2  of the valve  40  is connected to the nozzle  50 . 
     The flame retardant gas source  30  stores flame-retardant gas, such as nitrogen, carbon dioxide, or heptafluoropropane. 
     The fire detector  10  sends out a detecting signal if the fire detector  10  detects that there is electrical arcing in the container data center, the temperature in the container data center is higher than a first predetermined value, the rising rate of the temperature in the container data center is higher than a second predetermined value, or the smoke density in the container data center is higher than a third predetermined value. 
     The controller  20  receives the detecting signal of the fire detector  10 , and sends a control signal to the valve  40  to control the valve  40  to connect the flame retardant gas source  30  to the nozzle  50 . The flame-retardant gas in the flame retardant gas source  30  flows into the container data center and suppresses the fire. 
     The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above everything. The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others of ordinary skill in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those of ordinary skills in the art to which the present disclosure pertains without departing from its spirit and scope. Accordingly, the scope of the present disclosure is defined by the appended claims rather than the foregoing description and the exemplary embodiments described therein.
