Title: Air conducting device

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to air conduction, and particularly to an air conducting device in a computer. 
     2. Description of Related Art 
     Air conducting devices are often used in computers coupled with fans for dissipating heat from electronic components. A computer often includes a plurality of different heat generating components, such as CPUs, memories, and others. An airduct covers the heat generating components, and a fan is installed on or near the inlet to generate airflow to dissipate heat from the heat generating components within the airduct. However, different heat generating components may work at different temperatures, such that one with higher temperature may elevate the overall temperature in the airduct and affect the other components therein. In this way, the temperature of the affected heat generating components may exceed the temperature limit, and may be thereby damaged. In addition, when fewer heat generating components are installed, generated airflow exceeds the cooling requirements, translating to wasted energy and hardware.

     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , an air conducting device  50  is configured to assist the removal of heat from a plurality of first heat generating components, such as memories  20  and a plurality of second heat generating components, such as central processing units (CPUs)  14  by directing airflow flowing therethrough. The memories  20  are installed in a plurality of parallel slots  12  of a motherboard  10 . The memories  20  are optionally installed in the slots  12 . The heat generating components  14  are installed on the motherboard  10  adjacent to the slots  12 . The CPUs  14  may create more heat than the memories  20 . 
     The air conducting device  50  includes a body, baffle  55 , and a plurality of tongues  572 . The body includes a top wall  51  and two parallel sidewalls  53  extending downwardly therefrom. The top wall  51  is parallel to the motherboard  10 . An airflow passageway is defined by the air conducting device  50  for directing the airflow therethrough. The baffle  55  is parallel to the sidewalls  53  and extends downward from the top wall  51  to divide the airflow passageway into a first passageway  57  and a second passageway  58 . The first passageway  57  is capable of receiving the memories  20  therein, and the second passageway  58  is capable of receiving the CPUs  14  therein. 
     The tongues  572  perpendicularly extend from the top wall  51  towards the slots  12  in the first passageway  57 . Each tongue  572  is rectangular. Each tongue  572  corresponds to each slot  12 . A distal end of each tongue  572  is flush with a top surface of each slot  12 . Each tongue  572  is placed adjacent to one end of each slot  12 . The tongue  572  has a width that is greater than the memories  20  configured to be located in the plurality of slots  12 . A guide channel  574  is defined between two adjacent tongues  572  for steadily directing the airflow to remove heat from the memories  20 . 
     Referring to  FIG. 2 , the air conducting device  50  is mounted on the motherboard  10  to dissipate heat from two memories  20  and two CPUs  14 . Each tongue  572  is positioned corresponding to the location of each slot  12 . As an example, two slots  12  here are not allocated with memories  20 . Airflow  100  moves into the airflow passageway. Part of the airflow travels through the guide channel  574  in the first passageway  57 , such that the airflow is regularly directed by the tongues  572  regardless of the number of unused memories  20 . When one or more memories  20  is added or removed, heat dissipation efficiency in the first passageway  57  remains unaffected. The other part of the airflow through the second passageway  58  dissipates heat from the CPUs  14 . Accordingly, the air conducting device experiences steady heat dissipation efficiency, with no affect from the number of components deployed or the individual operating temperatures thereof. 
     It is to be understood, however, 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
