         FIG. 2  is an isometric, assembled view of an enclosure of  FIG. 1 . 
         FIG. 3  is similar to  FIG. 2 , but viewed from a different aspect. 
     
    
    
     DETAILED DESCRIPTION 
     It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure. 
     The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
       FIG. 1  illustrates one embodiment of an enclosure  100  of an electronic device. The enclosure  100  includes a chassis  10 , a power supply unit  30  which is received in the chassis  10  and a cover plate (not shown). 
       FIGS. 1 and 2  illustrate that the chassis  10  includes a bottom plate  11 , a front plate  12 , a rear plate  13 , and two side plates  14 . The bottom plate  11 , the front plate  12 , the rear plate  13 , and the two side plates  14  cooperatively define a receiving space  15 . A board (not shown in FIGS.) is located on the bottom plate  11 . The board is equipped with a first heating element  21  and a second heating element (not shown in FIGS). A cooling fan  25  is located on the second heating element. In one embodiment, the first heating element  21  is a graphics card and the second heating element is a CPU. 
     The front plate  12  is connected with one end of the bottom plate  11  and is substantially perpendicular to the bottom plate  11 . The front plate  12  defines a plurality of air inlets  121 . The airflow can pass through the air inlets  121  to enter into the receiving space  15 . The front plate  12  is equipped with a plurality of third heating elements  123  and a plurality of fourth heating elements  124 . The airflow can take away the heat of the third heating elements  123  and the fourth heating elements  124 . In one embodiment, the third heating elements  123  are hard disks and the fourth heating elements  124  are CD-ROMs. 
     The rear plate  13  is connected with another end of the bottom plate  11  and is substantially perpendicular to the bottom plate  11 . One end of the rear plate  11  defines an opening  131 . Two side plates  14  are fixed on two sides of the bottom plate  11  and are substantially perpendicular to the bottom plate  11 , the front plate  12  and the rear plate  13 . 
       FIGS. 1 to 3  illustrate that the power supply unit  30  includes a power supply (not shown in FIGS.), a fixing bracket  40 , and a power supply fan  50  received in the fixing bracket  40 . The fixing bracket  40  includes a first plate  41 , a second plate  42 , a third plate  43 , a fourth plate (not shown in FIGS.), and two parallel fixing plates  44 . The first plate  41  and the second plate  42  are perpendicular to each other. The first plate  41  and the second plate  42  define a plurality of air vents  45 . The third plate  43  is supported on the rear plate  13 . The third plate  43  is substantially perpendicular to the second plate  42  and is substantially parallel to the first plate  41 . The third plate  43  defines a plurality of air outlets  431  and an interface  435 . The airflow can pass through the air outlets  431  to go out of the enclosure  100 . The interface  435  is used to connect the external power supply. The fourth plate is rested on one of the side plate  14 . One of the fixing plates  44  is fixed on the bottom plate  11  to fix the fixing bracket  40  on the chassis  10 . The power supply fan  50  is fixed on the third plate  43  and is aligned with the air outlets  431 . 
       FIGS. 2 and 3  illustrate when in assembly, the power supply and the power supply fan  50  are located in the fixing bracket  40 . The power supply fan  50  is fixed on the third plate  43  and is aligned with the air outlets  431 . Then, the power supply unit  30  is completely assembled. The power supply unit  30  is placed in the receiving space  15 . One of the fixing plates  44  is fixed on the bottom plate  11 . The third plate  43  is fixed on the rear plate  13  and the air outlets  431  are aligned with the opening  131 . The fourth plate is fixed on the side plate  14 . Thus, the power supply unit  30  is fixed in the chassis  10 . The cover plate is fixed on the chassis  10  and the enclosure  100  is completely assembled. 
     When the interface  435  is connected with the external power supply, the heating element within the enclosure  100 , the cooling fan  25 , and the power supply fan  50  are all working. The cold airflow passes through the air inlets  121  and enters into the receiving space  15 . The airflow will enter into the cooling fan  25  after taking away the heat of the first heating element  21 , the second heating element, the third heating element  123  and the fourth heating element  124 . Then, the airflow passes through the first plate  41  and the air vents  45  of the second plate to enter into the power supply unit  30 . The airflow goes out of the enclosure  100  from the air outlets  431  under the drive of the power supply fan  50 . Thus, the heat within the enclosure  100  is dissipated out of the enclosure  100 . 
     It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, 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 present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
