BACKGROUND 
     1. Technical Field 
     The present disclosure relates to portable devices, and more particularly to a stand for a portable device. 
     2. Description of Related Art 
     Nowadays, portable devices, such as laptop computers, are popular. As the portable devices succumb to miniaturization and more functionality, the integrated circuits (ICs), such as CPUs, have become more complex. However, with this complexity more heat is produced and the compact internal spaces of the portable device are not enough to maintain sufficient airflow by conventional convection means. 
     Therefore, a heat dissipation device for a portable device is desired.

         FIG. 2  is an exploded isometric view of the laptop stand of  FIG. 1 . 
     
    
    
     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , a laptop stand  100  for a portable device, such as a laptop computer, in accordance with an exemplary embodiment includes two supporting members  110  and a heat dissipation device  130  detachably disposed between the two supporting members  110 . 
     Further referring to  FIG. 2 , the two supporting members  110  are substantially triangular, and parallel with each other. Each of the two supporting members  110  includes a sidewall  111 , an inclined wall  112 , a bottom wall  113 , and a rear wall  117 . The sidewall  111  is substantially triangular. The sidewall  111  may be a right-angled triangle. The inclined wall  112 , the bottom wall  113  and the rear wall  117  extend substantially perpendicularly from three laterals of the sidewall  111 . The inclined wall  112  inclines downwardly from the top end of the rear wall  117  to the front end of the bottom wall  113 , to form a supporting surface  1121  on a top of the inclined wall  112 , with a lower edge bending upwardly to form a stopping portion  114 . Therefore, the portable device (not shown) may be loaded on the supporting surface  1121  of the inclined wall  112  and prevented from sliding down the supporting surface  1121  by the stopping portions  114 . 
     Each of the two supporting members  110  further includes two mounting portions  115  which are located in a virtual plane parallel with the supporting surface  1121  of the inclined wall  112 . The four mounting portions  115  are disposed on opposite surfaces of the two sidewalls  111  correspondingly. Each mounting portion  115  defines a blind hole  116  in a top portion. Each mounting portion  115  defines a notch  118  communicating with the corresponding blind hole  116 . 
     The heat dissipation device  130  includes a substantially rectangular-shaped cover  131 , two fans  132  fixed in the cover  131 , and four fixing portions  134  extending from an outer surface of the cover  131  corresponding to the four mounting portions  115 . 
     A plurality of holes  1311  are defined in the cover  131  to allow sufficient airflow. Each of the four fixing portions  134  is substantially square-shaped. The four fixing portions  134  are located on opposite side surfaces of the cover  131  which face the two supporting members  110  correspondingly. The two fans  132  rotate in a plane parallel with the supporting surface  1121  of the inclined wall  112 , in order to accelerate the speed of the airflow, so as to dissipate the heat produced by the portable device supported on the supporting surface  1121 . 
     In assembly, the four fixing portions  134  are aligned corresponding to the four mounting portions  115 , and inserted into the blind hole  116  and the notch  118  from top to bottom, such that, the heat dissipation device  130  is assembled on the two supporting members  110 . In disassembly, the heat dissipation device  130  is lifted upwards relative to the four mounting portions  115  and disengages from the four mounting portions  115 , such that, the heat dissipation device  130  is disassembled from the two supporting members  110 , it is convenient for portability. 
     In use, the portable device is supported on the supporting surface  1121  of the inclined surfaces  112  of the two supporting members  110 . The heat dissipation device  130  is underneath the portable device without contacting with the portable device, when the fans  132  are actuated, heat produced by the notebook computer is dissipated, therefore, the internal circuit and component parts of the portable device are protected from damage. 
     In this embodiment, the mounting portions  115  are disposed on the supporting members  110 , and the fixing portions  134  are disposed on the heat dissipation device  130 . In other embodiments, the mounting portions  115  may be disposed on the heat dissipation device  130 , and the fixing portions  134  may be disposed on the supporting members  110 . 
     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 present disclosure, the present 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 present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
