BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to an adhesive air guiding device, and a motherboard with the adhesive air guiding device. 
         [0003]    2. Description of Related Art 
         [0004]    Typically, a fan is mounted in a computer chassis to direct air from outside into the chassis, for forming airflow in a direction to cool a plurality of electronic components on a motherboard mounted on the chassis. However, most of the electronic components each have a sidewall perpendicular to the direction of the airflow, which will block the airflow and affect heat dissipation of the electronic components.

     DETAILED DESCRIPTION 
       [0007]    Referring to  FIGS. 1 and 2 , an embodiment of a motherboard  10  is provided. The motherboard  10  is mounted in a computer chassis (not shown), and a fan  20  is arranged in the chassis adjacent to a front edge of the motherboard  10 . The fan  20  directs air from outside into the chassis to form airflow in a direction A towards the motherboard  10 . A plurality of electronic components  15 , such as connectors, are installed on the motherboard  10 . Each of the plurality of electronic components  15  includes a sidewall  17  perpendicularly facing the airflow direction A. 
         [0008]    A plurality of adhesive air guiding devices made of soft insulative fireresistant material are attached to the plurality of electronic components  15 . The plurality of adhesive air guiding devices include first adhesive air guiding devices  30  and second adhesive air guiding devices  40  having different shapes from the first adhesive air guiding devices  30 . Each of the first adhesive air guiding devices  30  is triangular-prism shaped, and includes a vertical adhesive surface  31 , a bottom surface  32  perpendicularly extending from a bottom of the adhesive surface  31 , and a slanted air guiding surface  33  connecting a top of the adhesive surface  31  and a front end of the bottom surface  32 . The adhesive surface  31  of each first adhesive air guiding device  30  has the same shape and size as the sidewall  17  of a corresponding electronic component  15 . Each of the second adhesive air guiding devices  40  is also triangular-prism shaped, and includes an rectangular adhesive surface  41 , a triangular bottom surface  42  perpendicularly extending from a bottom of the adhesive surface  41 , and two slanted air guiding surfaces  43  slanted extending from opposite sides of the adhesive surface  41  to connect to each other and perpendicular to the bottom surface  42 . The adhesive surface  41  of each second adhesive air guiding device  30  has the same shape and size as the sidewall  17  of a corresponding electronic component  15 . 
         [0009]    In assembly, the adhesive surfaces  31  and  41  of the first and second adhesive air guiding devices  30  and  40  are correspondingly stuck to the sidewalls  17  of the corresponding electronic components  15 , with the bottom surfaces  32  and  42  being supported on the motherboard  10 , and the air guiding surfaces  33  and  43  facing the airflow direction A. 
         [0010]    When the computer works, the airflow generated by the fan  20  flows towards the air guiding surfaces  33  and  43  in the direction A, and flows over the electronic components  15  along the air guiding surfaces  33  and  43 . In the process, the slanted air guiding surfaces  33  and  43  can guide the airflow, and reduce windage resistance, which will enhance heat dispersion of the motherboard  10 . 
         [0011]    In this embodiment, the first and second adhesive air guiding devices  30  and  40  are made of soft insulative fireresistant material. When there are some little electronic components, such as resistors or capacitors, near the plurality of electronic components  15 , the first and second adhesive air guiding devices  30  and  40  also can be assembled to the corresponding electronic components  15  with deformation. 
         [0012]    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 disclosure, the disclosure is illustrative only, and changes may be made in details, 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.
