Title: Electronic device with heat dissipation function

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to an electronic device with heat dissipation function. 
     2. Description of Related Art 
     Heat sinks are often mounted on electronic elements to dissipate heat generated by these elements. However, the hot heat sink may heat up the air inside an electronic device receiving the elements, and the heated air cannot be cooled rapidly. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views. 
         FIG. 1  is an exploded, isometric view of an embodiment of an electronic device. 
         FIG. 2  is an assembled, isometric view of  FIG. 1 . 
         FIG. 3  is a cross-sectional view of  FIG. 2 , taken along the line III-III. 
     
    
    
     DETAILED DESCRIPTION 
     The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. 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. 
       FIG. 1  shows an embodiment of an electronic device  10 . The electronic device  10  includes a housing  12 , a circuit board  14  received in the housing  12 , and a cover  16 . 
     An element  140  and a hollow partition portion  142  receiving the element  140  are mounted on the circuit board  14 . The partition portion  142  is made of materials that can not conduct heat. 
     The housing  12  defines an opening  122  in a side opposite to the element  140 . 
     The cover  16  is capable of conducting heat and includes a block  162  integrally formed on an inner surface of the cover  16 . 
       FIGS. 2 and 3  show that in assembly, the cover  16  is mounted to the housing  12  covering the opening  122 . The block  162  enters the partition portion  142  and contacts the element  140 . A distal end of the partition portion  142  opposite to the circuit board  14  contacts the inner surface of the cover  16 . 
     Because the cover  16  is capable of conducting heat, the heat generated by the element  140  can be conducted to the cover  16  through the block  162 , to be dissipated rapidly. Because the element  140  is received in the partition portion  142 , heat generated by the element  140  will not diffuse to other inner parts of the housing  12 , and the heat generated by the element  140  will not heat up the air inside the electronic device  10 . 
     It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
