Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a computer server system, and more particularly to a server of the computer server system. 
     2. Description of Related Art 
     Computer server systems are commonly used to process and store data and information in networks in the art. Typically, a computer server system includes a cabinet and multiple servers mounted in the cabinet. Each of the servers includes an enclosure, a plurality of electronic components and fans accommodated in the enclosure. The fans are configured for cooling the heat generated by the electronic components during operation. 
     As information technology continues to rapidly progress, old servers are continually required to be updated with new ones, to enhance the processing capacity of the computer server system. In this situation, the fans in the old servers are discarded together with the fans installed therein whether they are competent or not in heat dissipating for the new servers because the new servers generally have an internal layout different from that of the old servers. Thus, it is a waste for the fans, and accordingly the cost for updating the servers is increased. 
     Accordingly, what is desired is a server of a computer server system which can overcome the above-described limitations.

     DETAILED DESCRIPTION 
     Reference will now be made to the drawing figures to describe the present computer server system in detail. 
     Referring to  FIG. 1 , a computer server system according an embodiment of the present disclosure is shown. The computer server system includes a cabinet  10 , and a plurality of servers  20  stacked in the cabinet  10 . 
     The cabinet  10  is a hollow metallic cuboid housing. In  FIG. 1 , a front plate (not shown) of the cabinet  10  is removed for clarity. An access port  11  is defined in front of the cabinet  10 . Each of the servers  20  is flat and inserted into the cabinet  10  through the access port  11 . The servers  20  are parallel to each other and stacked in the cabinet  10  bottom-to-top. Two ventilating holes  12  are defined in top of the cabinet  10 . Heat dissipation fans (not shown) can be configured to align with each of the ventilating holes  12  for accelerating air exchange between the inner side of the cabinet  10  and the outside of the cabinet  10 . 
     Referring to  FIG. 2 , the cabinet  10  is provided with a rack  13  mounted therein for mounting the servers  20 . The rack  13  includes two guiding members  14  located at rear of the cabinet  10 . The two guiding members  14  are located at two opposite sides of the servers  20  respectively, and are elongated and extending along a stacking direction of the servers  20 . 
     Referring to  FIG. 3 , each of the guiding members  14  includes an elongated guiding plate  141 , two flanges  143  respectively extending from two opposite sides of the guiding plate  141 , and two mounting edges  145  respectively extending from the two flanges  143 . A surface of the guiding plate  141  is parallel with the direction that the servers  20  are inserted into the cabinet  10 . In the embodiment, the guiding plates  141  attach to left and right plates (not labeled) of the cabinet  10 , respectively. Two rows of guiding slots  142  are respectively defined in the two opposite sides of the guiding plate  141  along the height direction of the guiding member  14 . The guiding slots  142  are arc-shaped, and extend gradually upwardly from two lateral sides of the guiding plate  141  towards a top of the guiding member  14 . The guiding slots  142  are evenly spaced from each other. In this embodiment, a distance between every two adjacent guiding slots  142  in the same row is three times as the height of a single server  20 . The two rows of guiding slots  142  are symmetrical with each other, whereby each of the two guiding members  14  can be mounted on the left plate or the right plate of the cabinet  10 . Each of the flanges  143  of the guiding member  14  defines a plurality of entrances  144 , corresponding to the guiding slots  142 . Each of the entrances  144  aligns with a corresponding guiding slot  142  of the guiding plate  141  and communicates with the corresponding guiding slot  142 . Each of the mounting edges  145  defines a plurality of mounting holes  146 , mounting the guiding member  14  in the cabinet  10 . 
     Referring to  FIG. 4 , each of the servers  20  includes an enclosure  21 , a circuit board  22  mounted in the enclosure  21 , and a plurality of electronic components  23  such as processors mounted on the circuit board  22 . The enclosure  21  includes a rectangular base plate  211 , left and right sidewalls  212  extending upwardly respectively from left and right on lateral sides of the base plate  211 , and front and rear sidewalls  213  extending upwardly respectively from front and rear on lateral sides of the base plate  211 . The front and rear sidewalls  213  define a plurality of ventilating holes  214 . A fan module  30  is provided outside the enclosure  21  and mounted to the rear sidewall  213  of the server  20 . 
     Referring to  FIG. 5 , the fan module  30  includes a rectangular tray  31 , three fans  32  mounted on the tray  31 , a mounting bracket  33  for mounting the tray  31  on the server  20 , two pivots  34 , and a plurality of fasteners  35 . 
     The tray  31  includes a rectangular mounting plate  311 , two connecting plates  312  extending perpendicularly from the two opposite shorter lateral sides of the mounting plate  311  and two flanges  313  extending perpendicularly from the two opposite longer lateral sides of the mounting plate  311 . The mounting plate  311 , the connecting plates  312  and the flanges  313  cooperatively define a receiving space (not shown), receiving the three fans  32 . The fans  32  are mounted on the mounting plate  311  and arranged in a row. The mounting plate  311  defines three ventilating holes  316  therein, corresponding to the three fans  32 , wherein each of the fans  32  aligns with a corresponding ventilating hole  316 . The mounting plate  311  further defines a plurality of threaded holes  314  around each of the ventilating holes  316  for the fasteners  35  to extend through to mount the fans  32  on the mounting plate  311 . A rib  317  is formed on the mounting plate  311  between every two adjacent ventilating holes  316 . Each of the ribs  317  is elongated and perpendicular to the two flanges  313  of the tray  31 . The flange  313  and the rib  317  can enhance the mechanical strength of the mounting plate  311 , whereby the tray  31  is capable of holding fans of a larger size. The two connecting plates  312  each define a through hole  315  at the end. A guiding pole  318  protrudes outwardly perpendicularly from a middle portion of each of the connecting plates  312 . 
     The mounting bracket  33  includes a mounting beam  331  and two supporting arms  332  connected at two opposite ends of the mounting beam  331 . The two supporting arms  332  are parallel to and face each other. A plurality of mounting ears are formed on the mounting beam  331  and the two supporting arms  332 , respectively. Each of the mounting ears  333  defines a mounting hole  334 . The rear sidewall  213  of the server  20  defines a plurality of threaded holes  215 , corresponding to the mounting holes  334  of the mounting ears  333  of the mounting bracket  33  for mounting the mounting bracket  33  on the rear sidewall  213  of the server  20 . Each of the two mounting arms  332  of the mounting bracket  33  defines a through hole  335 , corresponding to the through hole  315  of the connecting plate  312  of the tray  31 . The tray  31  is located between the two mounting arms  332 . The through holes  315  of the two connecting plates  312  of the tray respectively align with the through holes  335  of the mounting arms  332  of the mounting bracket  33  for the two pivots  34  to extend through, respectively. Whereby, the tray  31  is pivotally mounted to the mounting bracket  33  between the two mounting arms  332 . 
     In assembling the servers  20  into the cabinet  10  of the computer server system, the fan module  30  is adjusted to maintain the same plane with the corresponding server  20  as shown in  FIG. 4 , whereby the server  20  is inserted conveniently into the rack  13  of the cabinet  10  through the access port  11 . When the server  20  is inserted into the rack  13 , the fan module  30  enters the cabinet  10  from the access port  11  first, and the corresponding server  20  follows. As the fan module  30  approaches the two guiding members  14 , the two guiding poles  318  of the tray  31  respectively enter corresponding guiding slots  142  of the guiding members  14  from corresponding entrances  144  of the guiding members  14 . The server  20  is pushed further into the cabinet  10  of the computer server system. This causes the tray  31  of the fan module  30  to rotate upwardly along the corresponding guiding slots  142  of the guiding members  14  until the guiding poles  318  of the tray  31  reach a top end of the corresponding guiding slots  142 . In this state, the tray  31  of the fan module  30  is erected to be perpendicular to the enclosure  21  of the server  20  where the fan module  30  is mounted, as shown in  FIG. 2  and  FIG. 6 . Other servers  20  without fan module  30  if needed can be stacked above the server  20  with the fan module  30  until the other servers  20  exceeds the height of the tray  31  of the fan module  30  above the enclosure  21 . Whereby, multiple neighboring servers  20  can commonly share the fan module  30  in the computer server system. In this embodiment, the height of the tray  31  of the fan module  30  is three times the height of the single server  20 , so that the fan module  30  can be commonly shared by three neighboring servers  20  (referring to  FIG. 2 ). 
     In the present embodiment, the fan module  30  is disposed outside the server  20 . An internal layout of the server  20  is irrelevant to the installation of the fan module  30 . Thus, when the servers  20  are updated with new ones, the fan module  30  can continue to be used on new servers  20 , thereby saving money and reducing cost. Furthermore, since the fans  32  are mounted to the outside of the server  20 , fans with greater size can be used to provide a more powerful airflow. Also, if a single fan  32  of the fan module  30  is damaged, the damaged fan  32  can be easily substituted by a new one without opening the enclosure  21  of the server  20 . In addition, multiple neighboring servers  20  in the cabinet  10  can commonly share a single fan module  30 , thereby reducing the assembly process. 
     It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the embodiments. 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.
