Title: Enclosure with sheilding assembly

Description:
BACKGROUND 
     1. Technical Field 
     The disclosure generally relates to enclosures with shielding assembles for shielding pipe holes. 
     2. Description of Related Art 
     Electrical devices, such as computers, include enclosures for receiving electronic components. Some electronic components may generate heat, and the heat needs to be dissipated from the enclosure. Traditional heat dissipation includes heat sink and fans. To reach high heat dissipation effect, water-cooling device is used. Holes are needed in the enclosure for receiving water pipes for water-cooling enclosure. However, dust or water may enter the enclosure through misfit holes in size for pipes will affect the electronic device. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. 
         FIG. 1  is a partial exploded view of an enclosure in one embodiment. 
         FIG. 2  is an assembled, isometric view of a shielding assembly of  FIG. 1 . 
         FIG. 3  is an assembled view of the enclosure of  FIG. 1 . 
         FIG. 4  is an enlarged view of a circled portion IV of  FIG. 3 . 
         FIG. 5  is similar to  FIG. 4 , but the shielding assembly is open. 
     
    
    
     DETAILED DESCRIPTION 
     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. 
     Referring to  FIG. 1 , in one embodiment, an enclosure  10  includes a rear wall  11 , a rail assembly  14 , and a shielding assembly  20 . Two pipe holes  112  are defined in the rear wall  11  for receiving pipes. The pipes may include an input pipe  40  and an output pipe  50 . 
     Referring to  FIG. 4 , the input pipe  40  is connected to an input valve  41 , and output pipe  50  is connected to an output valve  51 . 
     The rail assembly  114  defines two sliding spaces each braced by two side flanges  113 . The rail assembly  114  is fixed on the rear wall  11  adjacent to the pipe holes  112 . 
     Referring to  FIG. 2 , the shielding assembly  20  includes a top shielding device  21  and a bottom shielding device  23 . The top shielding device  21  includes a top fixing member  211 , two top poles  213 , and two top shielding members  215 . The top fixing member  211  includes a top fixing panel  2112 , two pairs of top locating members  2113 , and two top nuts  2115 . The top fixing panel  2112  is substantially a sheet. The two pairs of top locating portions  2113  are located on the top fixing panel  2112 . Each pair of locating portions  2113  is spaced and aligned along a vertical direction. Each pair of top locating portions  2113  defines a through hole. Each of the top nuts  2115  has inner thread. The each top pole  213  is located on each top shielding board  215 . Each top pole  213  has outer thread to engage with each top nut  2115 . Each top shielding board  215  defines a cutout  2151 . The cutout  2151  is substantially a semicircle. 
     The bottom shielding device  23  has substantially the same structure to the top shielding device  21 . The bottom shielding device  23  includes a bottom fixing member  231 , two bottom poles  233 , and two bottom shielding members  235 . The bottom shielding device  23  includes a bottom fixing member  231 , two bottom poles  233 , and two bottom shielding members  235 . The bottom fixing member  231  includes a bottom fixing panel  2311 , two pairs of bottom locating members  2313 , and two top nuts  2315 . 
     Referring through  FIG. 3  to  FIG. 5 , in assembly, the input pipe  40  and the output pipe  50  extends through the pipe holes  112  of rear wall  11 . The rail assembly  14  is fixed on the rear wall  11 . The top fixing panel  2112  and the bottom fixing panel  2311  are fixed on the rear wall  11 . Each top shielding board  215  with the top pole  213  and each bottom shielding board  235  with the bottom pole  233  are engaged with the top fixing  211  and the bottom fixing member  231 , respectively. Take one top shielding board  215  for example, the top nut  2115  is located between the pair of top locating portions  2113 . The top pole  213  extends through the pair of locating portions  2113  and is engaged with the top nut  2115 . The top shielding board  215  is substantially parallel to the rear wall  11 . 
     In use, the top nut  2115  is rotated, the top pole  213  moves relative to the top nut  2115  and the shielding board  215  is lifted up or dropped down. The bottom nut  2315  is rotated, the bottom pole  233  moves relative to the bottom nut  2315 , and the shielding board  235  is lifted up or dropped down. Each top shielding board  215  and each bottom shielding board  235  are moved in the sliding space of the rail assembly  114  towards each other, along a direction substantially parallel to the rear wall  11  to shield the pipe holes  112  around the input pipe  40  and the output pipe  50 . 
     It is also understood, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred 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.
