Abstract:
An electronic device enclosure includes an enclosure, a bracket fixed to the enclosure and an air deflecting plate fixed to the bracket. The bracket has an opening large enough to allow storage devices to pass therethrough. The air deflecting plate includes two pivot members defined on an air deflecting plate top edge and two securing members defined on an air deflecting plate bottom edge. The pivot members are fixed to a top of the bracket. The securing members are elastically fixed to a bottom of the bracket. The air deflecting plate is fixed to the bracket to cover the opening, which deflects air from outside of the bracket and facilitates heat dissipation.

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The disclosure generally relates to electronic device enclosures, especially to an electronic device enclosure with air deflecting plate. 
         [0003]    2. Description of Related Art 
         [0004]    In some computers and servers, a fan module is placed on the central processing unit (CPU) to remove heat generated by the CPU and other electronic components, and another fan module is secured to a rear plate or a front plate of a computer or server chassis and aligned with the CPU. However, because the another fan module described above is aligned with the CPU, heat generated by a disk drive module, placed on the front panel of the computer far away from the CPU, may not be dissipated efficiently. 
         [0005]    Therefore there is a need for improvement in the art.

     DETAILED DESCRIPTION 
       [0016]    The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. 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. 
         [0017]    Referring to  FIGS. 1 and 2 , an electronic device enclosure includes an enclosure  10 , a bracket  20  for holding storage devices (not shown), an air deflecting plate  30 , an air guiding bracket  50  for guiding air and a fan receiving bracket  60  for fixing fans (not shown). The air deflecting plate  30  is fixed to the bracket  20 . The bracket  20 , the air guiding bracket  50  and the fan receiving bracket  60  are fixed to the enclosure  10 . 
         [0018]    The enclosure  10  includes a base panel  11 , two substantially parallel side panels  13  and  14  that are substantially perpendicular to the base panel  11 , and a rear panel  15  substantially perpendicular and connected to the side panels  13  and  14 . A separating plate  40  is fixed to the base panel  11 . A number of air outlets  151  are defined on the rear panel  15 . 
         [0019]    The bracket  20  is capable of being fixed between the separating plate  40  and side panel  13 . The bracket  20  includes a bottom panel  21 , a top panel  23  substantially parallel to the bottom panel  21 , a front panel  25  and a rear panel  27 . The bottom panel  21 , top panel  23 , front panel  25  and rear panel  27  cooperatively define an opening  80  for the storage devices to pass through and be received in the bracket  20 . The bottom panel  21  defines a number of separating panels  211  for fixing the storage devices therebetween. Each separating panel  211  defines a number of through holes (not labeled) for allowing air therethrough. A bottom panel  21  side edge defines two fixing slots  213 . The top panel  23  is substantially perpendicular and connected to the front panel  25  and rear panel  27 . A top panel  23  side edge defines two fixing members  231 . Each fixing member  231  defines a position hole  2311 . The front panel  25  defines a number of air inlets  251 . The rear panel  27  defines an air outlet  271 , which is in communication with the air guiding bracket  50 . 
         [0020]    Referring to  FIGS. 3 to 7 , an air deflecting plate  30  top edge defines two pivot members  311  that correspond the fixing members  231 . An air deflecting plate  30  bottom edge defines two securing members  312  that correspond the fixing slots  213 . The air deflecting plate  30  defines a number of air guiding panels  33 . Each pivot member  311  defines a pivot hole  3110  that correspond the position holes  2311 . Two fasteners  70  pass through the corresponding position holes  2311  and pivot holes  3110  to pivotally fix the air deflecting plate  30  onto the top panel  23 . Each securing member  312  includes an upright portion  3121 . An upright portion  3121  bottom edge extends horizontally to form a bottom wall  3122 . A bottom wall  3122  side edge extends diagonally to form an elastic supporting arm  3123 . A portion of the supporting arm  3123 , which is substantially adjacent with a distal end of the supporting arm  3123 , extends horizontally to form a blocking member  3124  that is substantially parallel to the bottom wall  3122 . A distance between the upright portion  3121  and the blocking member  3124  is greater than a length of the fixing slot  213  in a direction perpendicular to the bottom panel  21 , side edge. A thickness of the air deflecting plate  30  is greater than that of the upright portion  3121 . 
         [0021]    Each air guiding panel  33  is substantially blade shaped with a width that increases from top to bottom. The air guiding panel  33  is located between the number of separating panels  211 , to divide the bracket  20  into several separate areas and improve heat dissipation efficiency. In one embodiment, the air deflecting plate  30  defines three air guiding panels  33  to divide the bracket  20  into four areas. 
         [0022]    The air guiding bracket  50  and fan receiving bracket  60  are fixed to the base panel  11 . The air guiding bracket  50  is located on a back side of the bracket  20 . The bracket  60  is located on a back side of the air guiding bracket  50  and abuts the rear panel  15 . The air guiding bracket  50  and fan receiving bracket  60  are in communication with the number of air outlets  151  on the rear panel  15 . 
         [0023]    Referring to  FIGS. 4 and 5 , in assembly, the air deflecting plate  30  is put on one side of the bottom panel  21  and top panel  23 . The pivot members  311  abut the corresponding fixing members  231  to align the pivot holes  3110  and the corresponding position holes  2311 . Two fasteners  70  pass through the pivot holes  3110  and position holes  2311  to fix the air deflecting plate  30  top edge on the bracket  20 . The air deflecting plate  30  is capable of rotating around the fasteners  70 . 
         [0024]    Referring to  FIGS. 5 and 6 , the air deflecting plate  30  is rotated around the fasteners  70 . The supporting arm  3123  inserts in the fixing slot  213 , the fixing slot  213  abuts the supporting arm  3123  and the supporting arm  3123  is elastically distorted. Rotating the air deflecting plate  30  until the bottom panel  21  side edge abuts the upright portion  3121 . An air deflecting plate  30  bottom edge abuts the bottom panel  21  side edge. The supporting arm  3123  is elastically returned a little, and the blocking member  3124  abuts a fixing slot  213  side edge to fix the securing member  312  in the fixing slot  213 . 
         [0025]    Referring to  FIGS. 8 and 9 , the assembled bracket  20  and air deflecting plate  30  are fixed onto the base panel  11  between the side panels  13  and separating plate  40 . The front panel  25  is adjacent to a base panel  11  front edge. The air guiding bracket  50  is fixed at the back of the bracket  20 . The fan receiving bracket  60  is fixed between the air guiding bracket  50  and rear panel  15 . In use, the cool air outside the bracket  20  is sucked into the bracket  20  by the number of air inlets  251  by the fans fixed to the fan receiving bracket  60 . Most of the cool air is deflected by the air deflecting plate  30  and cannot leak out from the opening  80 . The cool air displaces the warm air heated by the storage devices held on the bracket  20 . The warm air is blown out of the bracket  20  through the air outlet  271  and blown into the air guiding bracket  50  by the fans fixed to the fan receiving bracket  60 . The warm air passing through the fan receiving bracket  60  can be propelled out of the enclosure  10  through the number of air outlets  151 . Therefore, a heat dissipation efficiency of the storage devices is improved.
