BACKGROUND 
     1. Technical Field 
     The disclosure generally relates to servers, particularly to a server including a guiding air flow structure for guiding air-flow to electronic components that may easily overheat. 
     2. Description of Related Art 
     Many electronic components in an electronic device generate heat when operating. Therefore, when designing an electronic device, cooling systems designed in to dissipate heat generated by the electronic components to prevent the electronic components from overheating. 
     Many cooling systems include fans configured to force air to flow past the electronic components which are cooled accordingly. However, when there are many electronic components in the electronic device, the fans cannot always uniformly direct the air flow to each electronic component for dissipating heat. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     Referring to  FIGS. 1 and 2 , a server  100  includes a chassis  10 , a cover  20 , and an inside plate  30 . The chassis  10  includes a motherboard  11 , a number of electronic components  12 ,  13 ,  14 , and a number of fans  123 . The electronic components  12 ,  13 ,  14  are mounted on the motherboard  11 . The fans  123  are mounted on one end of the motherboard  11  for dissipating heat. 
     In the exemplary embodiment, the first electronic component  12  is a power supply disposed on the motherboard  11 . The second electronic component  13  is a hard disk, and the third electronic component  14  is a memory. A first clearance  15  is defined between the first electronic component  12  and the second electronic component  13 . A second clearance  16  is defined between the first electronic component  12  and the third electronic component  14 . 
     Referring to  FIGS. 3 and 4 , the cover  20  includes a main plate  21  and two opposite sidewalls  22  extending from opposite sides of the main plate  21 . The cover  20  is used for covering the chassis  10 . The inside plate  30  is mounted on the main plate  21  of the cover  20  by adhesive. A first bock  24  and a second block  25  are formed on the inside plate  30  for being received in the first clearance  15  and the second clearance  16 . The first block  24  and the second block  25  each have a main face  24   a ,  25   a  and are made of a flexible insulating material, such as rubber. Thus, the first block  24  and the second block  25  can be deformedly pushed to be easily received in the first clearance  15  and the second clearance  16 . Additionally, the insulating characteristic of the first block  24  and the second block  25  may prevent the electronic components from short circuiting. The shape and the arrangement of the first block  24  and the second block  25  are similar to that of the first clearance  15  and the second clearance  16 . In this exemplary embodiment, the first block  24  and the second block  25  are rectangular strips. 
     To assemble the first block  24  and the second block  25  to the chassis  10 , as shown in  FIG. 3 , the inside plate  30  is firstly mounted on the cover  20  by adhesive. As shown in  FIGS. 1 ,  5 - 6 , the cover  20  with the inside plate  30  is positioned on the chassis  10 . The first block  24  is received in the first clearance  15 , and its main face  24   a  is spaced apart from the motherboard  11 . Thus, a first airflow passage  18  is defined between the first electronic component  12  and the second electronic component  13 . The second block  25  is received in the second clearance  16 , and its main face  25   a  is also spaced apart from the motherboard  11 . Thus, a second air flow passage  19  is defined between the first electronic component  12  and the third electronic component  14 . 
     In use, when the fans  123  are operating, the first block  24  and the second block  25  to direct airflow from the fans  123  to respectively enter the first airflow passage  18  and the second air flow passage  19 . The airflow in first air flow passage  18  and the second air flow passage  19  is further directed to the electronic components  12 ,  13  and  14  for dissipating heat. 
     During testing of a conventional server  100 , it was found that the first clearance  15  and the second clearance  16  easily get hot. However, with the current design of the first block  24  and the second block  25 , the airflow of the fans  123  can be more precisely directed to the predetermined airflow passages for dissipating heat. Thus, the air flow of the fans  123  can be effectively allocated to cool the various electronic components. 
     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 the 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.
